Household Electrical Appliance Enterprises Reverse Logistics Network Planning

With the people's attention to the product quality and the environmental protection consciousness enhancement, the reverse logistics start to cause continuously attention of people. More and more scholars research the origin, the concept, the classification of the reverse logistics. Since western countries such as Europe and America begin to study reverse logistics from 90's of last century, only then this question was introduced to logistics management systemically and scientifically, and has yielded certain theory results and actual benefits.Under the premise that many industries enter meager profit time, for seeking new profit point of growth, more and more enterprises hope to protect environment, control production cost, increase profit, promote the quality of customer service, and then enhance competitive ability of enterprises, through implementing reverse logistics effectively.Reverse logistics of discarded and used household appliances, also named as the recycling of waste electric appliances, refers to the activity of collecting, transporting and storing discarded and used household appliances so as to achieve the goal of recycle using of regional resources and reduce treatment. Establish old appliance reverse logistics network is fit the sustainable development request, the enterprise make good progress on the service level, further reduce costs, and excavation profit fountainhead.Firstly, under the introduction of the background which reverse logistics comes into being and the present situation that the domestic and foreign research, this article introduces the related theory about reverse logistics. In the chapter 2, introduce the relate concepts, the origin, the classification of the reverse logistics. and the current situation of worn out electrical appliances. In chapter 3, introduce the construction of worn out electrical appliances reversion logistics network model. Than analysis the environment, the characters and the classification of worn out electrical appliances reversion logistics network. Secondly, in the chapters 4, to study the old appliance reverse logistics recycling network design. Based on the statements mentioned above, a MILP (Mix Integer Linear Programming) model is given to optimize the logistics system, and the locations of various facilities are decided. Finally, in the chapters 5, an example that considers the logistics system of a refrigerator company in an area is taken to demonstrate the model presented in the dissertation, than use Iinggo8.0 soft to resolve the model.
