Research Of Modeling And Optimizing For Logistics Networks Based On One Product

Logistics network is one of advanced forms of transportation. In the face of limited natural resources and disposal capacity, logistics network can realize efficiently the synthetical goal of optimal utilization of natural resources and reduction of the cost. The research of logistics network is a useful task. It can reduce the cost of the companies. It can optimize the whole resources. The purpose of the thesis is to study network models and arithmetic. At last it proves the thesis right with the examples. The thesis finishes the framework of logistics network after studying the basic theories. It summarizes the methods and theories of logistics network and analyses the intension, class and models. And then, it constructs the models of the supplier and distributors in the view of static condition. It evaluates the logistics network with Analytic Network Process(ANP) models. The models of the thesis have significant theory value for solving the problem of the cost, dispatch and evaluation and so on.Through this thesis, it can tell the following result and conclusion:(1)It summarizes the studying conditions and differences at home and abroad and points out the trend of logistics network. It analyses the intension, class and summarizes the models of logistics network and genetic algorithm.(2) It analyses the whole factors in the purpose of minimization of the whole cost. It finishes the models of the supplier and distributors. At the beginning, it analyses the logistic network and gets the members and structure and the models according to the process of logistic network. Then it put forward the problems of models and solves the hypothesis of the models and the material parameter. At last the example validates the model of bi-level programming with genetic algorithm.(3) It studies the model of logistic network in the dynamic condition. First, it analyses the uncertainty problems and the origin of the network. Then it summarizes the methods of expectation model, stochastic programming and blur programming to resolve the uncertainty of logistic network. At last the example validates the dynamic model with certainty figures.(4) It studies the performance evaluation model of logistic network to queue all of logistic network. It bases on the evaluating index and Analytic Network Process(ANP).The purpose of the model is to queue all of networks and improve the problems.The innovative point of this thesis is that it summarizes the working models and evaluation models. The thesis solves the bi-level programming model in the view of the supplier and distributors. And then it solves dynamic programming models in the dynamic condition. At last it solves the evaluation models in the view of qualitative analysis and quantitatively determine. It also proves the thesis right with the examples to assure the effectiveness and value.
