Adopting smart supply chain and smart technologies to improve operational performance in manufacturing industry

The manufacturing industry plays a crucial role in the economy of many countries, but there is a lack of expertise in implementing smart supply chains and smart technologies. This study aims to investigate the relationship between smart supply chains, smart technologies, and operational performance in the manufacturing industry. A survey questionnaire was conducted among registered manufacturing industries, and the results were analyzed using Smart PLS to test 10 hypotheses. Four hypotheses were supported out of 119 responses received through simple random sampling. The study suggests implementing instrumented supply chains using smart technologies can enhance operational performance. The findings provide valuable insights for policymakers, academics, and industry practitioners to improve the competitiveness of the manufacturing industry. This research emphasizes the importance of smart supply chains and smart technologies in achieving operational excellence, and further studies are necessary to address the identified limitations and contribute to a deeper understanding of the role of smart technologies in the supply chain’s digitalization.


Introduction
The objective of managing the supply chain is to deliver the right amount of products to customers at the right time and under suitable conditions, and at a lower cost.The supply chain can be complicated and unpredictable, resulting in supply-demand imbalances such as excess inventory, stock-outs, and missed deadlines.These issues have been a subject of interest in business administration research.To address these challenges, the "smart supply chain" concept as emerged. 1 A Smart Supply Chain is a modern networked commercial framework different from localized models and focuses on systematic supply chain implementations.It involves using statistics to manage complexity and risk, from planning to decision-making.However, companies must know the sources and costs associated with using statistics.Misuse can result in excessive risk and costs for the company. 2 highlight the importance of companies being aware of these issues.
Smart technology is a non-living technology that uses AI technology, algorithms, and big data analysis to provide cognitive awareness to objects.Over the years, the Internet of Things (IoT), big data, blockchain, and artificial intelligence have been recognized as smart technologies that can bring new innovations to traditional supply chain processes. 3hese technologies can enhance the efficiency and competitiveness of Industry 4.0 and manufacturing by connecting all resources within industrial organizations and the supply chain, 4 which is a significant contemporary debate in legal and moral philosophy. 5According to the researchers, technology is essential for the success of an industry, and it can be achieved by efficiently using technology for transmitting processed goods to and from the organization.To improve operational performance in the manufacturing industry, this study will concentrate on the smart supply chain, which includes interconnected, instrumented, intelligent, and smart technologies. 6he research problem revolves around the uncertain link between smart supply chains and information system flexibility, 7 leading to a lack of understanding among management and workers on using smart technologies in the supply chain. 8This issue is supported by, 8 who found that organizations face challenges in understanding how to effectively utilize smart technologies in their supply chain operations.Moreover, the manufacturing industry in Malaysia faces specific challenges in deciding whether to invest in smart supply chains and smart technology due to their high cost. 9This highlights the practical concerns and financial implications associated with adopting smart technology in the supply chain. 10further emphasize the difficulty of integrating smart technologies into existing supply chain systems, providing empirical evidence to support the claim that integration challenges hinder the adoption of smart supply chains in the industry.
Furthermore, the impact of smart supply chains and smart technology on small and medium-sized enterprises (SMEs) and their operational performance remains unclear. 11,12This demonstrates the need for research specifically focused on the effects of smart technology implementation on the performance of SMEs, considering their unique operational contexts and resource constraints.The effectiveness of digital transformation in improving cooperation within the supply chain has been identified as an area requiring further research. 13This highlights the importance of investigating how smart technologies can enhance collaboration and information sharing among supply chain partners to improve overall efficiency and responsiveness. 14Additionally, there is a need for more research on optimizing material flow in the supply chain through the implementation of smart technology. 15,16argue that understanding how smart technology can enhance material flow management is crucial for achieving improved supply chain performance, emphasizing the practical relevance of this research problem in current business applications.
Despite estimates of the benefits of smart technology, there is a lack of theoretical evidence on how it can improve operational performance. 17This highlights the gap in knowledge regarding the underlying mechanisms through which smart technology impacts operational performance, necessitating further investigation to provide a theoretical basis for its potential benefits.Moreover, there is a lack of conceptual models and practical implementation, despite various studies exploring the potential of smart supply chains and technology. 8This underscores the need to develop comprehensive conceptual frameworks and practical guidelines that can guide organizations in successfully implementing and utilizing smart technology within their supply chains 18. Addressing these gaps in the literature will contribute to a better understanding of the role and potential benefits of smart technology in the context of smart supply chains.
Based on the above discussions, this study has two research questions; what is the impact of smart supply chain (specifically, instrumented supply chain, interconnected supply chain, and intelligent supply chain) and smart technologies on the operational performance in the manufacturing industry?Do smart technologies mediate the relationship between smart supply chains and operational performance in the manufacturing industry?Therefore, to answer the research questions, the study aims to investigate the impact of smart supply chain and smart technologies on the operational performance in Malaysia manufacturing industry and further examine the mediating effect of smart technologies in the relationship between smart supply chain and operational performance in the manufacturing industry.
This study establishes a strong connection between these factors and aims to achieve operational excellence and enhance the organization's environmental skills in information processing.The research provides theoretical knowledge and practical examples that contribute to existing knowledge by demonstrating the correlation between smart supply chains, smart technology, and operational performance.It focuses on three indicators of the smart supply chain: interconnected supply chain, intelligent supply chain, and instrumented supply chain.By understanding these indicators, companies can make targeted investments or utilize them to enhance operational performance with the help of smart supply chains.The study also reviews recent research on how smart technology leads to smart supply chain decisions in the manufacturing industry, offering practical insights for organizations looking to invest in or leverage smart technologies to strengthen the smart supply chain, optimize inventory management, aid capacity planning decisions, and improve overall operational performance.

Literature review
This study examines the theory of operational performance in the manufacturing industry.According to, 18 previous research has suggested that enhancing the level of smart technology could enhance the performance of the manufacturing supply chain.However, not all technological advancements can ensure operational performance in the manufacturing industry.Furthermore, many businesses may lack the necessary skills to improve their smart technology capabilities, resulting in a less clear overall impact of smart supply chain techniques on operational performance in the manufacturing industry. 19

Operational performances in manufacturing industry
There has been a decline in the manufacturing industry's relative contribution to the country's economy since the late 1990s due to its export-oriented nature.This has resulted in a decrease in the country's global economic participation.However, as per the Department of Statistics report in 2021, the manufacturing industry experienced growth in various sub-sectors like transport equipment, non-metallic mineral products, basic metal and fabricated metal products, and electrical and electronics products.The high-capacity utilization rate in sub-sectors such as petroleum, chemical, rubber, and plastic goods also contributed to the industry's success. 20This success is reflected in the considerable increase in exports and IPI for several important trade partners of Malaysia. 21

Smart supply chain
As the supply chain becomes more complex, companies are investing in creating a segmented system that integrates physical capacity with digital infrastructure, called a supply chain structure, with innovations such as smart containers, warehouses, ports, shelves, and manufacturing.Managing these systems and obtaining the actionable intelligence required for smart supply chain management (SSCM) has become essential, particularly in the context of Industry 4.0. 22However, there is some concern among warehouse workers about job security as these smart technologies may potentially replace their jobs. 23Companies that educate their employees on the benefits of technology and implement practices with experienced staff can have a more secure future.When combined with the Internet of Things (IoT), these systems can generate large amounts of data that can be used to improve operations through demand forecasting, reducing common problems, and identifying optimal solutions.Data collected by IoT sensors can be analyzed by artificial intelligence (AI) for better decisionmaking. 24strumented supply chain.According to, 25 the instrumented supply chain is a type of supply chain that will move quickly towards a scenario where researchers have realtime visibility to everything, and effectively utilizing this information will become a vital competitive advantage.An instrumented supply chain strategy includes more visibility and performance management, supply chain optimization and transparency, and customer demand sensors and simulators.The ultimate objective of supply chain sustainability is efficient instrument utilization, where sensors, meters, actuators, GPSs, and other devices and systems will gradually generate supply-chain data.Visibility in the supply chain will increase as shipping containers, cars, products, and components report on themselves, eliminating the need for labor-intensive tracking and monitoring.Plans, commitments, sources of supply, pipeline inventories, and customer needs will all be displayed in real-time dashboards on yet-to-be-conceived devices. 26terconnected supply chain.This study will adopt the classification of "interconnected supply chain" proposed by, 25 which describes it as a more intelligent value chain that involves increased engagement not only with customers, suppliers, and IT systems but also with the items involved in the production process.Such interconnectedness would encourage greater collaboration and provide a more comprehensive view of the supply chain.While little empirical evidence supports the claim that global supply chains can be coordinated and integrated to maintain high performance, organizations are still pursuing this objective. 27Some researchers have found that global partners collaborate in horizontal business flows and share information vertically, resulting in cost savings in information processing and leakage.These ecosystems are complex and pose operational risks, reconciliation challenges, and potential fraud and security issues.Many leaders are using blockchain technology to safeguard the authenticity and security of goods as they move across regional and global borders.
Intelligent supply chain.According to, 25 an intelligent supply chain is a system that will explore various limitations and options to assist executives in evaluating trade-offs and simulate different courses of action.It can learn and make decisions independently, without human intervention, and adapt to disruptions by rearranging its networks.It can also access tangible assets such as manufacturing infrastructure, fulfillment centers, and transportation fleets on demand through virtual exchanges.In addition, it will be used for making real-time decisions and predicting future events. 28o achieve intelligent supply chain management, companies must adopt cutting-edge technology such as artificial intelligence (AI), machine learning (ML), predictive analytics, unified commerce, and big data to optimize the supply chain and gain a competitive advantage. 29

Smart technologies
According to, 30 smart technologies such as Industrial IoT, big data analysis, and cloud are key enablers of the manufacturing transformation.These technologies encompass a range of features incorporated into devices that enable them to be intelligent. 31The present study examines the mediating role of smart technologies in enhancing operational performance within smart supply chains in the manufacturing industry. 32Smart devices have sensors that gather data, analyze and infer, communicate with other smart devices, and act accordingly.To accomplish this, they require a certain level of computational power, one or more actuators, and communication capabilities.Amazon's Echo home assistant devices are an example of such a service provider.

Underpinning theories
This study utilized the Resource-Based View (RBV) theory to provide a theoretical framework to examine the smart supply chain's role in enhancing organizations' performance through smart technology. 33The RBV theory emphasizes that a company's resources and capabilities are valuable, rare, and difficult to imitate and are the key sources of sustainable competitive advantage.The study under discussion examines the evolution of the smart supply chain theory from individual machine automation to IoT-enabled interconnected systems. 34The rapid development of technologies such as cloud computing, blockchain, and IoT has led to agile and flexible smart supply chains. 35Smart technology is crucial to mediating smart supply chains and operational performance. 30However, existing studies on big data have mainly focused on technical debates, and research on smart technologies and smart supply chain management should improve operational performance. 35Figure 1 illustrates the conceptual framework of this study.

A more intelligent supply chain has the potential to learn and make decisions without human involvement autonomously and can restructure its networks when disruptions occur. 30Advanced analytics and next-generation optimization software are utilized by organizations and firms to improve their supply chain outcomes and decisionmaking, according to. 48As a result, the intelligent supply chain is regarded as a renaissance in sustainability performance and an efficient tool for achieving optimal performance.The new supply chain aims to create a largescale intelligent infrastructure that integrates data, information, physical things, goods, and business operations by utilizing advancements in semiconductors, computer science, and other engineering technologies. 49Intelligent supply chain factories can leverage global teams, intelligent analytics, and dynamic systems to fulfill orders throughout the value chain. 48Using simulation analysis, an intelligent supply chain can help manage capital investment and emergency management and analyze flexibility aspects such as customer requirements, prices, time, and quality. 50Therefore, one of the significant areas of research in supply chain management is how companies can handle interruptions and create backup plans to manage them effectively. 51The above statements lead to the below hypothesis H3: There is a positive effect of an intelligent supply chain on operational performance.
According to, 30 smart technologies such as sensors, RFID tags, GPSs, and other equipment are expected to generate supply-chain data that people have traditionally created.Mutual support for hardware sensor technologies and software is necessary to collect, regulate, and process the vast amount of data available. 52Logistics software development has evolved rapidly, leading to a more complex supply chain management process that centers on anticipating requests, forming profitable partnerships, and improving operational effectiveness. 53According to, 8 organizations integrating various technological advancements are better positioned to exploit their features and achieve higher benefits and production levels.Smart supply chains have emerged due to the rapid development of technologies such as the Internet of Things, big data, artificial intelligence, and blockchain.These technologies have significantly changed the management of production, transportation, distribution, and marketing operations by supply chain participants, resulting in reduced transaction and operation costs. 54Additionally, technological solutions in the form of an integrated social channel have enabled effective management of partner relationships and shared strategic knowledge across organizational boundaries, leading to improved procurement, supplier management, and service quality.The above statements lead to the below hypothesis H4: There is a positive effect of the instrumented supply chain on smart technologies.Supply chains equipped with monitoring devices will engage at unprecedented levels with not only customers, suppliers, and IT systems but also with the products traveling through the supply chain, resulting in enhanced collaboration and a more comprehensive understanding of the supply chain.IT advances have enabled the integration of information flows, improving collaboration throughout the supply chain.Smart technology offers enormous possibilities for integrating software and material across different platforms, infrastructures, and production systems. 55have identified the impact of an interconnected supply chain on sustainability performance management.One key aspect of smart supply chains is the interconnected supply chain, which integrates systems up and down the supply chain.The idea of interconnectedness is reinforced by the transformative impact of integrative technologies like Big Data and Internet-of-Things on supply chain architecture. 56The above statements lead to the below hypothesis: H5: There is a positive effect of an interconnected supply chain on smart technologies.
Businesses use the term intelligent supply chain to describe the use of advanced analytics and optimization technologies to improve supply chain performance and decision-making. 57Smart technologies, which enable programmable, communicable, memorizable, and associative devices, require businesses to build a flexible structure for optimal information flow, leading to greater adaptiveness 8.An intelligent supply chain allows real-time communication with many supplier partners and benefits all supply network partners by reducing costs and improving planning and execution.Smart technologies can facilitate the adoption of sustainable supply chain practices.To achieve smart growth using sophisticated information technologies, smart supply chains and service operations are integrated into contexts. 58esides, the goal of a smart supply chain (SSC) is to establish a smart and interconnected system by utilizing cutting-edge technologies, mainly emerging ICT, to link the operations of different supply chain partners, including suppliers, manufacturers, maintenance, repair, and operations (MRO) providers, and transporters. 59Suggested that the intelligent supply chain involves simulating supply chain events and is supported by technologies that allow the creation of various scenarios in advance based on future situations, leading to more efficient and effective supply chain management and the ability to assess and mitigate risks proactively.The above statements lead to the below hypothesis: H6: There is a positive effect of intelligent supply chains on smart technologies.
Adopting smart supply chain practices can enhance operational performance, leading to optimized production and benefits across manufacturing industry infrastructure and production systems. 60Implementing smart technologies can improve data collection, enabling the industry to respond to operational challenges and ultimately improving supply chain efficiency.However, these advancements can pose challenges for organizations that struggle to keep up.Vendor Managed Inventory (VMI) is a technique sellers use to improve supply chain processes, offering benefits to various stakeholders 29 .Explain that smart technologies refer to physical objects or entities enhanced with digital qualities.This concept is sometimes referred to as digitized artifacts.These technologies possess fundamental attributes such as programmability, addressability, sensitivity, communicability, memorability, and associability, allowing corporate interconnection and insights. 61Digital transformation enables external collaboration in the digital supply chain and supports internal collaboration within organizations.For example, it facilitates collaborative planning and execution of business processes through exchanging information and digitizing processes. 54The above statements lead to the below hypothesis: H7: Smart technologies positively affect operational performance.
This study aims to examine how smart technology can act as a mediator between instrumented supply chains and operational performance.Smart technology is considered an application in manufacturing and service supply chains, which can enhance the company's competitiveness by improving industrial operational efficiency and performance. 38Integrating smart technology with the instrumented supply chain enables real-time monitoring of all operational activities through devices installed in the system, reducing holding and shortfall costs.Adopting RFID technology can lead to greater profits than the conventional approach. 5,18Furthermore, the adoption of Smart Supply Chain technology has the potential to replace current CPFR procedures in the logistics system and establish provenance along the production process.This technology facilitates efficient coordination and communication between all trading parties, creating a framework for strong networks between diverse partners. 48Digital transformation can enhance customer service and external cooperation activities in the digital supply chain by collecting vast amounts of data from various sources. 62This allows customers and end-users to become experts on product and service offerings.Therefore, this study will explore the mediation of smart technologies between Instrumented supply chain and operational performance.The above statements lead to the below hypothesis: H8: Smart technologies mediate the relationship between instrumented supply chain and operational performance.
Smart technologies have made the supply chain highly interconnected, and any disruption or compromise to these technologies can result in expensive consequences.The smart supply chain is characterized by high levels of contact with customers, suppliers, and IT systems and encompasses all entities, assets, IT systems, and goods that flow through it.Modern information and communication technologies connect the supply chain to the production environment and enhance operational performance.This study aims to increase the total profit of the smart supply chain by reducing the unreliability among supply chain participants, which researchers have found to be a drawback of this management approach. 26According to, 43 highly interconnected supply systems are vulnerable to risks.The characteristics of such systems include integration, intelligence, adaptiveness, and self-optimization.The smart supply chain is a dynamic process that involves vertical and horizontal integration, technology development, and business innovation, as stated by. 18Smart supply chain technologies can facilitate real-time communication between upstream and downstream supply chain participants, which can be integrated into supply, production, and distribution processes to reduce channel costs and increase operational efficiency. 33ompromise or disruption to smart technology in the interconnected supply chain can result in costly repercussions, similar to physical disruptions in operational performance.The above statements lead to the below hypothesis: H9: Smart technologies mediate the relationship between interconnected supply chains and operational performance.
According to, 8 supply chain operational performance results from successfully coordinating traditional business activities related to manufacturing finished goods.The intelligent supply chain raises environmental and social responsibility concerns, which can prevent financial losses and enhance operational efficiency.The impact of new technologies such as big data, the Internet of Things, cyber-physical systems, blockchains, and 3D printing on Industry 4.0's smart supply chains is examined using a systematic review of academic and professional literature.Besides, 42,31 suggest that effective coordination of traditional business activities within and across the company, which involves converting raw materials into finished goods, leads to supply chain operational performance.However, smart supply chains pose significant environmental and social responsibility challenges, which must be addressed to prevent significant financial losses and improve operational efficiency. 63The above statements lead to the below hypothesis: H10Smart technologies mediate the relationship between intelligent supply chains and operational performance.

Research methodology
The study employed quantitative methodologies, which involved collecting and analyzing numerical data by distributing close-ended questionnaires.The questions were adapted from past research, and respondents can answer the questionnaire using a six-point and seven-point Likert scale.The questionnaire consisted of two sections (A and B), with section A gathering personal information such as gender, age, education level, designation, and work experience.Section B required respondents to indicate their level of agreement with each survey item on a Likert scale ranging from 1 (strongly disagreed) to 6 (strongly agreed) and 1 (strongly disagreed) to 7 (strongly agreed).The purpose of section A was to gather general information about the participants.In contrast, Section B covered operational performance, the role of smart technology, and the smart supply chain.
The pretesting process in survey research involves testing survey questions and questionnaires on target population members to ensure reliability and validity before distribution. 44In this study, the survey instrument is pretested by three academics and practitioners to confirm its content validity.A pilot study used a convenient sampling technique with 30 samples to test the adequacy of research instruments and assess questionnaire feasibility.According to the Federation of Malaysian Manufacturers (2022), Malaysia has 3300 manufacturing companies.As 11 suggested, the minimum sample size is determined using G*Power to be 119 respondents.Simple random sampling is the chosen technique to distribute the questionnaire to the manufacturing industry, with the unit of analysis being an organization.Furthermore, this study collects quantitative data using a modified questionnaire distributed through an online survey.The researcher will follow up every 2 weeks to ensure the target number of respondents is reached within the 4 month data collection period.Microsoft Excel is used for descriptive analysis, and Smart-PLS 4.0 software is used for Partial Least Square Structural Equation Modelling (PLS-SEM) analysis, including testing for reliability, validity, discriminant validity, and hypotheses testing.

Results
Table 1

Measurement model assessment
The study utilized Partial Least Square Structural Equation Modelling (PLS-SEM) to analyze and obtain results.The measurement model's convergent and discriminant validity were evaluated using Smart-PLS Version 4.0, where an acceptable outer loading value should exceed 0.50 (Hair  et al., 2019).Any factor loading less than 0.50 should be removed, but none was found in this research.The final model (shown in Figure 2) includes the independent variable, SSC, comprising three indicators: ICSC (5 items), INSC (3 items), and ITSC (3 items).The mediating dependent variable, ST, has six items, and the dependent variable, OP, has seven items.The concept of convergent validity is a subset of construct validity. 28It demonstrates the correlation between two measures that are supposed to measure the same construct.We use all the devices that can be uniquely identified 5.076 1.070 ST 3  We use all the devices aware of and respond to environmental changes 5.176 1.179 ST 4  We use all the devices that can send and receive messages 5.420 1.226 ST 5 We use standardized communication protocols 5.588 1.118 ST 6  We use all devices that identify with other devices, places, or people  recommended value of 0.50.Additionally, all CR values fell between 0.724 and 0.960, which exceeded 0.7, indicating the reliability of all constructs.Discriminant validity aims to check for the high correlation between constructs in a model and avoid multicollinearity issues in latent variable research.It ensures that non-overlapping components in the research remain distinct.The Heterotrait-Monotrait (HTMT) correlation ratio should not exceed 0.90; f it does, the Fornell and Lacker criterion must be used instead. 28Since the HTMT results did not meet the minimum requirements, the Fornell and Lacker criterion will be used and reported in Table 3 of this research.The result shows that the extent to which the correlation between different constructs is lower than the correlation between items measuring the same construct.Therefore, it means the results are reliable and that they are accurately measuring the constructs of interest.

Structural model assessment
Ten direct hypotheses are tested using Smart-PLS four and evaluated with the bootstrapping method, generating new samples to assess statistical accuracy.The bootstrapping method utilizes a replacement technique to create hypothetical samples for testing estimated values Soumyaa Rawat, 2021).Acceptance of hypotheses is based on a p-value less than 0.05 (<0.05) and a t-value greater than 1.645 (>1.645).Table 4 displays the results of directional hypotheses.INSC has a significant positive impact on OP at (t-value = 0.11 and p-value 0).H2 predicts a positive relationship between ICSC and OP, but the result shows insignificance at (t-value = 0.16 and p-value = 0.334).ITSC has an insignificant impact at tvalue = 0.033 and p-value 0.345.As a result, H1 is supported, while H2 and H3 are not.Additionally, H4 predicts a positive impact of ICSC on ST (t-value = 0.11 and p-value = 0.14).H5 predicts a positive impact of  INSC on ST, resulting in t-value = 0.12 and p-value = 0. ITSC also positively affects ST, with a result of t-value = 0.033 and p-value = 0. Therefore, H4 is not supported, and H5 and H6 are supported.Lastly, H7 predicts a positive impact of ST on OP, with a result of (t-value = 0.11 and p-value = 0.137), but the hypothesis is insignificant.Table 5 presents the results for the proposed hypotheses.H8 suggests a positive mediating effect of ST between INSC and OP (t-value = 1.044 and p-value = 0.148).H9 proposes a positive relationship between ICSC and ST, leading to OP with a t-value of 0.611 and a p-value of 0.271.Finally, H10 predicts that ST mediates the relationship between ITSC and OP, with a t-value of 1.072 and a p-value of 0.142.Therefore, H8 is supported, while H9 and H10 are not supported.
The measure of the model's predictive accuracy is the Coefficient of Determination, R 2, which shows the variance in the dependent variable explained by the associated independent variables.A higher R 2 value indicates a better prediction in the PLS path model.Three rules of thumb are used to interpret the R 2 values, where values of 0.75, 0.50, and 0.25 represent the independent variable's strong, moderate, and weak contributions toward the dependent variable.In this study, the standardized estimate of the structural model indicates that the R 2 value of ST is strong at 0.84, while OP is at a moderate to weak level of 0.409.Besides, Table 4 shows the effect size, also known as F 2 , which measures the influence of the exogenous construct on the endogenous construct.Cohen (1988) proposed that F 2 values above 0.35 indicate a large effect, values of 0.15 indicate a medium effect and values of 0.02 indicate a small effect.As shown in the table, two hypotheses, H5 and H6, have a large effect on the F 2 value (1.517 and 1.32, respectively), while the remaining five have a small effect (H1, H2, H3, H4, and H7).Furthermore, to evaluate the predictive accuracy of the R 2 value, the Q 2 value, which is calculated through blindfolding, is significant.According to Hair (2017), a Q 2 value greater than 0 for the reflective endogenous variable indicates the acceptability of the predictive path model.As indicated in Table 6, the Q 2 values for ST and OP are 0.816

Discussion
This study aimed to investigate the relationship between smart supply chain (SSC), smart technologies (ST), and operational performance (OP) in the Malaysian manufacturing industry.
The study identified Interconnected supply chain (ICSC), instrumented supply chain (INSC), and Intelligent Supply Chain (ITSC) as indicators of SSC.The results showed that INSC positively impacts OP (H1 supported).This finding is consistent with the previous research of, 10,5 who suggested that sensor-based technology could improve cost calculation accuracy.However, ICSC did not positively affect OP (H2 not supported), contrary to the study by, 44 which may be due to the potential threats to IT security.The study also found that ITSC did not positively affect OP (H3 not supported), possibly because of the significant financial resources and extensive research needed for its implementation.The extent of the effect of the relationship between smart supply chains and information system flexibility is still unknown. 8he study did not find evidence supporting the hypothesis that intelligent supply chain systems positively affect smart technologies (H4 not supported).However, the study's findings suggest that the lack of Information-sharing standards may be responsible for this discrepancy with previous research.While previous research has shown the potential for integrating technology such as big data and the Internet of Things into supply chain design, 31 there is little practical research to support the use of smart technologies to assist intelligent supply chain systems on a large scale in Malaysia's manufacturing industry.The study did find that intelligent supply chain systems positively affect smart technologies and that this integration can help ensure traceability throughout the supply chain while reducing risks (H5 supported).Additionally, the study found a direct connection between intelligent supply chain systems and smart technologies (H6 supported), suggesting that advanced technology may be necessary to support a flexible structure that optimizes information flow and increases adaptability. 49he study discovered that smart technologies do not positively impact operational performance (H7 not supported), which was not the expected outcome.The data mostly came from small companies that do not use smart technologies, resulting in inaccurate records.However, the study found that INSC has a positive effect on operational performances when mediated by smart technologies (H8 supported), which aligns with the findings of. 39,44This suggests that INSC can improve industrial efficiency and performance, enhancing a company's competitiveness.The study also found that smart technologies do not mediate the relationship between interconnected supply chains and operational performance (H9 not supported), consistent with 19 research.Smart technology is vulnerable to disruption or compromise in the interconnected supply chain, resulting in costly repercussions throughout the supply chain, much like disruptions in physical processes.
The current study found that the mediating effect of ST on the relationship between ITSC and OP was not supported (H10 not supported).Although these results differ from some published studies 23,37,55 they are consistent with focusing on the operational performance of smart supply chain execution functions.These results may be due to the numerous unexplored benefits of digitalization in supply chains.However, the disruptive nature of organizational transitions may cause delays in the implementation of ITSC and the mediating role of ST on operational performance, which is a concern for the manufacturing industry.
Overall, implementing smart supply chains and technologies can bring numerous benefits to enterprises, such as increased efficiency, improved visibility, and enhanced decisionmaking.However, managers often face several challenges and practical limitations when attempting to implement these advanced systems.Firstly, the cost and return on investment (ROI) considerations involved in infrastructure, software, hardware, and skilled personnel can be significant and require careful evaluation.Besides, integrating new technologies with existing legacy systems is complex and time-consuming, necessitating strategies to ensure a smooth transition without disrupting daily operations.Furthermore, effective data management and security protocols are crucial to handle the vast amounts of data generated by smart supply chains and protect sensitive information.In addition, skill gaps and workforce training become important for organizations to bridge the knowledge divide and ensure employees can leverage emerging technologies effectively.The most critical is overcoming organizational resistance to change, as employees may fear job displacement or be unfamiliar with new systems, requiring clear communication, training, and support.From another perspective, collaborating with suppliers and partners can be challenging due to differing technological capabilities, necessitating effective communication and alignment of objectives.Lastly, scalability and flexibility should be considered to accommodate future growth and changing business environments, with managers selecting scalable solutions and adaptable systems.Therefore, addressing these challenges and practical limitations requires careful planning, strategic decision-making, and proactive management.Managers must assess their organization's specific needs, conduct thorough feasibility studies, and develop comprehensive implementation strategies to integrate smart supply chain technologies into their enterprises successfully.
Last but not least, one of the advanced technology, artificial intelligence (AI), has had a significant and transformative impact on supply chain management.It enables more accurate demand forecasting by analyzing historical data and market trends, optimizing inventory levels, and improving customer satisfaction.AI algorithms optimize inventory in real-time, reducing carrying costs while ensuring adequate stock availability.In warehouse and logistics operations, AI automates tasks, improves efficiency, and reduces errors.AI-powered technologies enhance supply chain visibility and transparency, enabling real-time tracking, traceability, and risk management.Besides, predictive maintenance algorithms predict equipment failures, minimizing downtime and optimizing asset utilization.AI also supports risk management by analyzing diverse data sources and providing early warnings and mitigation strategies.Lastly, AI-powered analytics facilitate enhanced decision-making, providing valuable insights and recommendations for strategic planning and operational improvements.In summary, AI enables organizations to achieve greater efficiency, visibility, agility, and competitiveness in today's dynamic business landscape.

In conclusion, this study investigates how smart supply chains and smart technologies impact the operational performance of the manufacturing industry in Malaysia.Out of the 10 hypotheses examined, four were deemed significant, while six were not.The study suggests that to improve operational performance, it is crucial for the industry to prioritize the implementation of a smart supply chain that integrates interconnected and intelligent supply chains alongside smart technologies.It was observed that among the three indicators of a smart supply chain, only the instrumented supply chain is commonly employed in day-to-day operations.However, the goal is to raise awareness and encourage more businesses to adopt smart supply chains in order to enhance their operations.Understanding these indicators enables companies to make targeted investments or leverage them to boost operational performance through the adoption of smart supply chains.From a practical perspective, the study examines recent research on how smart technology influences decisionmaking within smart supply chains in the manufacturing industry.This knowledge can assist other organizations in making investments or learning how to utilize smart technologies to strengthen their smart supply chains effectively, address issues such as buffer stock and underutilized inventories, support capacity planning decisions, and ultimately enhance operational performance.Future research endeavors could delve into the development of smart supply chains for the manufacturing industry, explore the economic value of their applications, and investigate industry practices.

Limitation and recommendation
This study provides valuable insights for both theoretical and practical implications, but it also has limitations.The main limitation is that the survey questionnaire did not receive responses from medium and large manufacturing companies, which may have led to some deviation in the final research results.Future research could gather additional data sources from more established manufacturing industries to address this.The turnover of organizational structures or staff also posed a challenge in collecting data.To increase the response rate in future research, regular follow-ups could be advised.The researcher suggests that FMM should collect and update contact details to facilitate communication with the company person in charge.
