Multi-Period Closed-Loop Supply Chain Network Equilibrium Model With Uncertainty Demand Under The Electronic

Supply chain network equilibrium problem is study how to adjust the company's making decision so that it can get the maximizing profit in a fierce competition environment.Accor ding to the relevant literature that have reading studying and summarizing of the framework about the problem.In this paper,we study two kind of a problem.One of that is multi-period closed-loop supply chain network equilibrium model with uncertainty demand under the electronic commerce,and another is base on this model,consider how the manufacturer's and recycler's credibility to affect the supply chain network,then build a new model about two enterprise commitment period of delivery supply chain network.It will show that this paper's research has theoretical and practical significance for the enterprise descion.Firstly,the first part of this paper is to introduce a background and significance of the research,then summarizes current research of the supply chain network equilibrium model,and analyzes the main ideas and methodology of existing supply chain network equilibrium models.After that,in the second chapter,we introduce the relevant theoretical knowledge about this paper which is the basis for the next study of this kind of problem.Secondly,the main part of the paper is to study multi-period closed-loop supply chain network equilibrium model with uncertainty demand under the electronic commerce,in this type supply network model which we study in many times,the producers and retailers can sell goods through the network to demand market,while the recycler only recovery material from market and use to remanufacturing,we analyzes the behavior of four levels in supply chain network which the producers,retailers,demand market and recycler,and establish those four level's maximization benefit model.Basic on existing theory that to equivalent the model in variational inequalities and solved,then give a numerical examples by using the modified projection algorithm calculation.The results show established model is reasonable.Finally,we establish the supply chain model about promised delivery,to punishment the enterprise if they miss delivery time,and study a problem that maximizing the profit model of manufacturers and recycler with trading restrictions.According to the constraints that have given,establish a proper mathematical model,through equivalent theory to solve the variational inequality and give\ an economic explanation about the model.Then construct three specific examples,in which one of those cases,improve the manufacture's production efficiency and this producer traded with retailers before trading period,another examples study one of the manufacture has more low product cost.As a result the manufacturer producing more commodity,and have greater benefits from this situation,also these result validate the model establish is reasonable.In the end of this paper,we summarize the work that we have done and a directing of future research.Combine with the contents of previous literature research,to point out Personal views.
