Study On Key Factors Of Product Update Process In Supply Chain

With the development of science and technology, globalization of market competition and diversification of needs, product updates faster and faster and product life cycle is getting shorter. Manufacturing enterprises must constantly update their products to meet market demand. Moreover their product must be good quality and cheap. So they will not be eliminated in the fierce market competition. However, they on their own strength are very difficult to achieve, they must work together with their suppliers, customers, so much as the entire supply chain. Competition is no longer competition between enterprises, but between supply chains.In the existing literature on product supply chain management, research is mostly on new product development, but lack of on the product update, old products and new products in alternate stage. This dissertation is focus on some problems of supply chain management when product update. Four aspects are studied in the thesis.1. The key factors of product update is studied in supply chain at first. Based on product life cycle and supply chain theory, driving factors product update are analysed. Product update process is defined and key factors of product update are studied systemically. Multi-dimension and Multi-hiberarchy model is built on product update. And the measure method of product update degree is given.2. Reconfiguration of manufacturing resource in product update process is studied. Two phase classification method of update product parts is put forward. And supplier selection strategy and process model are studied when manufacture enterprise in the especial phase of product update. Muti-hiberarchy fuzzy evaluation and selection method is given.3. End-Of-Life spare parts procurement decision-making is studied. When the regular production of the product is over, its components and parts has been discontinued but customer service still has to be guaranteed for quite a long time, enterprise must store spare parts through last buy. Last buy model is established based on newsboy model. Enterprise may acquire spare parts through remanufacturing spare parts from used products. The model of optimal combination of last buy and remanufacturing spare parts is set up through Dynamic Programming procedure.4. Integrative analysis and simulation of multi-factors of product update is studied. Simulation model is constructed by use of System Dynamics and relevant simulation software.W company is a diesel motor manufacturer, whose product update from the European II emission standard to Europe III emission standard. Based on the background, applied research is done and the result is analyzed.At last, the reach result and the direction in the future are concluded and prospected.
