Research On Optimization Methods Of Reverse Logistics Value Chain

One of the most important functions of value chain theory is leading enterprises'field of vision from original strategic analysis to the basic layer of activities, and integrating resources from top to bottom so as to produce cooperation effect and share effect. Therefore, it is necessary to put basic layers'activities into value chain frame to be reviewed and demonstrated from the beginning of strategic analysis. Only value chain established by connecting strategic points and specific activities can make supply chain carry out its high efficiency. Logistics is the basic activity in operation courses, it also can be considered as an activity process in basic layers in enterprises. In environment project, how to embed reverse logistics into value chain systems so as to improve operation efficiency of reverse logistics and increase reusing rate of resources is a problem that obtains more and more attentions. Core enterprise in logistics value chain is taken as a research object; from the view point of core competence maintenance, basing on reverse logistics activities detailed analysis, a reverse logistics optimization theory structure is established and corresponding optimization method is studied. The main contents included in this paper are as follows.Through the analysis of present research on reverse logistics value chain concepet and optimization, a field direction worthy of deep research is introduced. The origin of logistics value chain theory is stated; the concept of reverse logistics value chain is put forward; according to purchaser drive mode, producer drive mode and"purchaser-producer"double drive mode, reverse logistics value chain is categorized; different competition advantages of different modes of reverse logistics value chain are analyzed; used productions recovery logistics and goods return from customers logistics value chain are described; correlative interest entities'actions are researched; optimization point recognition method, optimization driven, optimization strategy and optimization support system of reverse logistics value chain are studied so as to establish a foundation for subsequent research on reverse logistics value chain optimization methods.Frame optimization method of reverse logistics value chain is studied. According to different drive modes, used productions recovery logistics and goods return from customers logistics network are researched respectively. First, system characteristics of reverse logistics are analyzed; then, basic processes and main cause relationship of factors in two kinds of reverse logistics network are discussed; System Dynamic flow charts of reverse logistics value chain network which have the"social-economic-logistics"characters are established respectively, the influence factors in the charts are described. Through the simulation of key value points, the improvement method of processes and factors can be found, so as to optimize reverse logistics value chain.Extract method of reverse logistics value chain is studied. First, extract drive, extract form, and risk control problems of reverse logistics value chain are put forward; then, extract processes are analyzed qualitatively, network analysis chart is established, influence factors under diference drive modes are analyzed in detail so as to quantify decision-making process and help enterprises reform its value chain; in the same time, the input course of Super Decisions software used to simulate the decision-making process is introduced; finally, income harmonization problems between government and core company, core company and third-party logistics company are analyzed.Integration method of reverse logistics value chain is studied. Route and facility integration, information integration and resources integration are discussed. Robust Optimization method is used to establish a reverse logistics route and facility integration profit model under uncertain states aiming at the circumastance that used production recovery logisics and goods return logistics happen in the same time; environment influence factors are integrated to above model to carry out"cost-environment"multi-object decision-making; integration methods under other circumstances are also analyzed; then, information processes, information integration entities, and information management system function module are researched; finally, reverse logistics'resources characters are studied used resource economy theory, a conceptual model integrating interior and exterior resources is established. The research on integration method is helpful for integrating enterprises'value chain system, and can be used to optimize reverse logistics value chain.ADSL recovery logistics incident is taken as a case study to validate the theory and methods provided in this paper. First, Heilongjiang Communication Company ADSL recovery project background is introduced, its reverse logistics value chain and value-added distribution curve are described; then, 3 kinds of optimization strategies are discussed; finally, the specific optimization methods related to Heilongjiang Communication Company ADSL repair center actual situation are deeply researched.
