Vietnam is currently among the top-five textile and apparel exporters, and the industry is considered quite attractive to foreign investors. Nevertheless, the global textile and garment industry is experiencing important changes. The three main producing regions in the world are China, Southwest Asia (India, Pakistan, Bangladesh, and Turkey), and ASEAN. In order to maintain its positioning and to establish stable and sustainable Vietnam textile and apparel development, there must be radical changes. Due to this necessity, the authors conducted this study by using grey forecasting to predict and reflect the condition of businesses in the period of 2017-2020, together with combining a DEA model to help businesses select the most appropriate strategic partner in the supply chain in order to achieve economic goals and promote the strength of the businesses partaking in the association. Besides, this helps businesses exploit market opportunities and take advantage of the capabilities of the textile and apparel industry.
Semiconductor industry grows rapidly in recent years. It has an impact on the economies all over the world. For the mass production requirement, the wafer size starts to be increased from 300 to 450 mm. The technician cannot handle a large number of wafers since the size and weight of the wafers are increased. The automated material handling system has become the basic requirements of the wafer factory, and it is important to provide on-time delivery service and shorten cycle time to meet customer demand for different priority products. Hence, this study proposed an effective conveyor dispatching rule, which can reduce the handling delay of hot lots and detect the dispatching of lots with different priorities. The simulation experiments were conducted by building a 450-mm manufacturing environment and compared the nearest job first with conveyor dispatching rule. The results are sound. The conveyor dispatching rule can reduce 97.57% of the total average delivery variable time of hot lots and 0.28% of normal lots. This study proves that conveyor dispatching rule can efficiently improve productivity and reduce the cycle time of hot lots in every load configuration.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
