In production/inventory control systems, the goal of the controller is to generate sophisticated decisions by controlling the order rate and inventory level. This paper aims at modeling a dynamic-stochastic production/inventory control system under two sources of variability (uncertainty) including uncertainties on demand rate and frustrating rate. The study deals with obtaining a robust optimal design of a Proportional-Integral-Derivative (PID) controller in in the stochastic control system. For this purpose, a new robust simulation-optimization method in the class of computational intelligence is proposed. To cope with the unknown distribution of uncertainty, the crossing weighted uncertainty scenarios are combined with the proposed method. Within this study, a new sequential robust efficient global optimization is proposed to make a trade-off between optimal and robustness terms in final optimization results. Finally, a numerical case with simulation experiments is conducted to demonstrate the advantages of the proposed policy in terms of optimal result, robustness, and computational cost.

The research aimed to evaluate the impact of operations management practices (OM) on the competitive advantage of Saudi Arabian Small and medium-sized enterprises (SMEs). It further aimed to analyse the mediating role of supply chain management practices (SCM). The research design of the study was quantitative, and primary data was gathered using a close-ended survey questionnaire. In this research, 383 participants were recruited belonging to different industries. The analysis was conducted on SmartPLS with SEM as the primary technique. The results revealed that operations management practices significantly helped in gaining competitive advantage, and supply chain management practices mediated the relationship partially. However, this research was limited to SMEs of Saudi Arabia, therefore, it can be improved in the future with the inclusion of other factors and considering other countries as well. Precisely, it is recommended that the SMEs should focus on leveraging their core competencies or identify an area which can give them a definite competitive advantage and further ensures that customer needs are translated on the product planning.

The objective of this article is to assess the impact of supply chain relationship quality on supply chain performance and financial performance through environment uncertainty of high-tech agricultural enterprises in Vietnam. The study conducted data analysis based on 198 agricultural firms applying high technology in high-tech agricultural group and in all of Vietnam. The results show that, agricultural enterprises applying high technology with supply chain relationship quality had a strong positive impact on supply chain performance and supply chain flexibility.

Livestock sector including pig is developing in Vietnam, which plays a crucial role in the economic structure of Vietnam and meets the demand of Vietnamese. The study was involved 120 pig farmers, 3 retailers, 3 wholesalers, 12 middlemen, 3 slaughterhouses, 12 sellers, 3 processors, and 12 consumers in three districts who were chosen as respondents in the value chain. The study was implemented to determine the value chain and benefit distribution of pig industry in Tra Vinh province. Snowball sampling and purposive method were used in this study. The results show that there were three channels of pig in Tra Vinh province during the context of African Swine Fever (ASF). There were three value chains which were found out in the value chain of pig industry. Middlemen played an important role in the value chain. Both of three passed through slaughterhouse as their slaughtering service. The shortest value chain is from farmer – middlemen-cum-seller – consumer. Farmers contributed a high value-added share in the value chain. It could be concluded that in Tra Vinh province, the longer value chain, the higher price the consumer takes. We suggested that the improvement of the number of pig and stabilization of the value chain of pig industry are the current mission and the strategy to be implemented.

The objective of this paper is to assess the impact of supply chain quality integration on green supply chain management, environment performance and financial performance. The data was analyzed on 568 Vietnamese tourism businesses. Results were analyzed using SPSS 22 and Smart PLS 3.6 software. The results show that supply chain quality integration had a positive impact on green supply chain management and financial performance. Green supply chain management also had a positive impact on environment performance and financial performance. Green supply chain management also played a full mediating role in the relationship between supply chain quality integration and financial performance. However, neither size nor institutional pressure played any moderating role in the relationship between green supply chain management and financial performance and environment performance.

The geographical constrain of small islands associated with fisheries commodities, is due to the lack of insufficient infrastructure and socio-economy characteristics, in addition to the nature of fisheries commodities where the durability and inconsistency of quality and quantity of the particular region become very vulnerable to uncertainty of supply chain. This study aims to formulate a strategy to mitigate the existing effect of uncertainty supply chain in Southeast Maluku Regency. The data mining approach with naïve bayes was used to determine the clusters of areas with high to low interdependency in villages and sub-districts. In addition, the House of Risk (HOR) was used to identify the cause of risks and provided the most effective and efficient alternative strategy to mitigate the uncertainty of the fisheries' supply chain sector. Data were collected from 28 villages to obtain 322 datasets by using the purposive sampling technique and expert assessment method for the data mining process, and HOR, respectively. The result show that the village location, resources, and fishermen's ability to sell and buy their gear were the main determinant factors of interdependency. Furthermore, there were, at least, three clusters of interdependencies with the integration of a web-based system to help spread information to fishermen and aquaculture farmers. In conclusion, policymakers need to be more adaptable to the use of information technology to efficiently improve the welfare and performance of coastal communities, aside from constantly enhancing the region's infrastructure.

The study aims to explore supply chain innovation in retail trading of Small and Medium Enterprises (SMEs) in different regions of Abu Dhabi by considering the contribution of supply chain integration, supply chain orientation, and competition capability, along with the mediating role of intelligent information systems. Online questionnaires were used to collect the relevant information from managerial employees at target firms. A total of 357 responses were considered suitable for the purpose of the study. All the constructs were internally and externally estimated to be reliable and valid based on factor loading values, Cronbach’s alpha, composite reliability, average variance extracted, and discriminant validity. Supply chain integration, orientation, and competition capability were considered as the key contributors to supply chain innovation. However, in the case of supply chain orientation towards intelligent information systems and of intelligent information systems towards supply chain innovation, the association was weak. Intelligent information systems had a weak relationship with competition capability, supply chain integration, orientation, and innovation. The results have real-world implications for management and policymakers of retail trade SMEs in Abu Dhabi. Using the results and conclusions, upper management can shape corporate policy to improve supply chain integration, supply chain orientation, and competition capability, resulting in supply chain innovation in retail trading SMEs.

This study aims to explore the role of personal value and broaden knowledge of perceive value and performance in business-to-business markets. A sample of 189 distributors was surveyed to test the theoretical model. The study focuses on paint and coating industries. Data was analyzed with partial least squares structural equation modeling (PLS-SEM) method. The hypothesized relationship that personal value drives information sharing, logistic performance, information support, and product quality, which is based on existing literature in channel behavior and relationship marketing, did not fit well with our data. Some drivers did not have significant effect on distributors’ perceived value. Finally, the distributors’s perceived value is a determinant of business performance. The paper also systematically addresses the antecedents of customer perceived value and performance from the perspective of distributors. The results of this study suggest that manufacturers should invest more effort in personal value with their key distributors to enhance the value of the relationships with those distributors. The managerial implications of the findings are considered, and the limitations along with future research directions in B2B channel relationship are discussed.
