Supply chain management is an important competitive strategies used by modern enterprises. Effective design and management of supply chains assists in the production and delivery of a variety of products at low costs, high quality, and short lead times. Recently, data envelopment analysis DEA has been extended to examine the efficiency of supply chain operations. Due to the existence of intermediate measures, the usual procedure of adjusting the inputs or outputs, as in the standard DEA approach, does not necessarily yield a frontier projection. The current paper\r\ndevelops a DEA model for measuring the performance of suppliers and manufacturers in supply chain operations. Additive efficiency decomposition for suppliers and manufacturers in supply chain operations is proposed....
This study was aimed at establishing the validity of the measures and metrics for automobile green supply chain performance measurement. The study involved statistical tests using 16 measures and 72 corresponding metrics. These statistical tests include exploratory factor analysis to investigate the construct validity of the measures and their metrics, a confirmatory factor analysis to test the model fitness and a multiple regression analysis to test the criterion validity of the measures. From the results obtained, the validity of the measures and their corresponding metrics has been established. The paper culminated with recommendations for further studies....
This paper proposes a framework that seeks to denote the relationship and promote a better alignment between the evolution of supply chain strategies and technologies. In the supply chain strategy, the focal shift in strategy has been from lean supply chain to a combination of lean and agile supply chain, whereas in supply chain technology the focal shift has been from individual and dyadic to global, inter-organisational systems. Examples of these systems include Vendor-Managed Inventory and Web-based Electronic Data Interchange. These systems increase visibility of information within the supply network and require a high level of trust between the trading partners. Since most inter-organisational systems are developed by IT vendors, the concepts of visibility and trust must be understood by these vendors and translated into the systems they develop. The proposed framework emphasizes the focus on fit and alignment between progress in supply chain strategies and IT strategies that would potentially enable agility as well as trust and visibility within the supply network....
Sustainability is a major subject of interest in the field of business and environmental management. Many previous studies have emphasized the trade-off between economic activities and their negative effects on the environment. Moreover, previous studies have focused principally on manufacturing enterprises; however, only a few studies conducted thus far have concerned themselves with the\r\nlogistics sector. This study fills these gaps by testing the causal relationship between proactive green management and the sustainable performance of logistics enterprises in Korea. Additionally, as compared with previous literature that discusses the partial relationship between environmental variables and firm performance, this study synthesizes the factors of green awareness and green\r\nstrategy that may affect green logistics management, based on a total systematic structural equation model (SEM). SEM has advantages in examining the causal relationship between green logistics practice and business performance. Our results demonstrate the positive impact of green awareness and green logistics practice on logistics performance, whereas the influence of green strategy on\r\nlogistics performance is apparently not significant....
The purchasing function of a firm directly affects its competitive ability. Purchasing managers need to periodically evaluate the performance of suppliers in order to retain those who meet their requirements. There are various criteria for supplier selection and evaluation. This report provides a guideline for establishing supplier selection criteria for purchasing activities of University Procurement Department in accordance with some purchasing topics. The analytic hierarchy process (AHP) decision making process functions in terms of the multi-criteria analysis for cost, flexibility, quality, delivery, and variety. The present report provides an accurate and easy classification in supplier attributes that have been prioritized in the model....
