Integrated Simulation Study Of Supply Chain Operation Law In The E-Commerce Environment

The theoretical studies of e-commerce have been more mature,currently, the most studies of many scholars are the issues of e-commerce in the application course of actual business or industry.In recent years, the advance of related technology has promoted the development of mobile commerce, many scholars begin to turn their focus study to the mobile commerce application areas.Whether in e-commerce or mobile commerce,the traditional study methods are mostly theoretical and empirical analysis methods, they only did a certain degree of qualitative analysis to issues. This paper will combine e-commerce with product supply chain and value chain, use integrated simulation method, based on the related theories and research at home and abroad, from the qualitative and quantitative perspectives, study supply chain operating law in the e-commerce.Firstly, use agent simulation to study the issue of supply chain operating performance. Construct a product supply chain,it is the abstraction of complex supply chain network structure in the real world,node businesses use minimum and maximum inventory strategy, establish and implement agent models for nodes in supply chain.Simulate and study the inventory levels,average inventory costs, order or producing quantity and cost,shortage cost and the purchase waiting time of customers of businesses each day, use the average cost of supply chain and customer waiting time as the indicators to evaluate the supply chain operating performance.In addition,through an optimized simulation experiment, investigate the specific inventory strategy of business in the case of supply chain cost minimized, provide a reference of business inventory management in the real life.Secondly, this paper uses integrated simulation method to study the impact of product demand evolution in e-commerce on the supply chain operating.By analyzing summarize the key factors of product demand evolution,use system dynamics to construct causal diagram, system flow diagram and dynamic equations,from the aspects of qualitative and quantitative to describe the evolution phenomenon of user demands.The supply chain has two cases which are decided by manufacturer provides Internet sales or not,model agent models of nodes in supply chain.The simulation experiments investigate the effect of some effect factors to product demand evolution and supply chain operating indicators.The above study is about supply chain operational issues affected by product flow, however,value stream also exists in supply chain,its emergence always accompanies with logistics,so the fourth chapter in this paper study the value stream in the value chain,design a product value chain,design agent and implement agent models of nodes in value chain.Use discrete event method simulates the constant updating phenomenon of products. Use system dynamics method to built product demand evolution model, and integrate it with the agent and discrete event models. Simulation experiments investigate the effect of parameters in the model to value changes in the value chain.Finally, the paper makes a summary,points out the encountered problems in the study, and the future improving direction.
