At present, the process and management of global market expansion are more and more differentiated, in order to shorten the product life cycle, reduce the quantity and reduce the delivery time of customers. Supply chain business processes, functional units and integrated management components are the same elements in all supply chains, which determine their management and structure.

Lambert and the others. (1998) Germany & amp# 64257; The management of night elf is "an integrated key business process, from products, services and information provided by users, through original suppliers, to customers and other stakeholders".

It is not only independent modeling and processing, but also enjoys the information among suppliers, suppliers, customers, suppliers and customers. Focusing on improving external integration is called "Vokurka, Rumas". This goal is to optimize the management of the whole chain, not through personal ef &；; # 64257 spot; Efficiency is maximized, but the whole system, in which there is a balanced distribution of risks among the participants of the system.

Research on supply chain management; # 64257; Ganesha is divided into three viewpoints: competitive strategy, centralized strategy with face value of 64257 rm and; ef & amp# 64257; Scientific operation. Ganeshan believes that the whole supply chain of global behavior can only use dynamic evaluation method. Based on helicopter dynamics, modeling and simulation are suggested as concrete tools for supply chain to cope with unpredictable market changes.

It is easy to understand that information and 64258 wedding vows play a vital role in the supply chain, because every step of the design and management functions, they are in&; # 64258; All supply chain self-service business processes. Change production capacity, rapid response, denomination 64258; Flexibility, denomination 64257; The ability of genes and the ability to create new genes are summarized as important competitions. According to Zhang Dexiong (1999), the production and logistics system of (2000) model helicopter is an important research field, because data and 64258 wedding vows seem to be the bottleneck of the whole supply chain, especially in the development of e-commerce.

Regarding the structure of this model, Brooks and Klimt (1996) relate the complexity of the model and calculate the complexity sum of some component connections. Recently, the submission selection process of general guidelines has been formulated. Under special circumstances, some authors, such as Pidd( 1996) and Brooks and Klimt (2000), have studied the modeling method.
