Study On Scheduling Model&Algorithm Over A Pallet Poling System

With the development of the world economy and people’s living standards improve, the logistics industry has become a very important service industry, the state and the government also attaches considerable importance to the development of the logistics industry. In order to promote the development of the logistics industry, the relevant responsible departments had developed a series of guidelines and policies. Through these, not only the logistics industry has been rapid development, and also played a positive role in promoting the upgrading of industrial structure, and also to enhance the competitive strength of the country’s economic and international competitiveness, and to make China’s logistics industry to keep up with the international pace.Tray as an important appliance in the field of logistics is more and more concern and attention from all walks of life. The right way to use the tray, and can effectively improve the utilization of the tray and shorten the time of operation of the logistics, the logistics process smoother. But the actual use of the tray, tray recycling difficult, serious waste of resources, circuitous transportation repeated transport and multiple loading and unloading are quite common and serious. In order to quickly solve the above problems, it is proposed Pallet Systems, pointed out that it can be good to solve these problems encountered in real life, and to improve the operational efficiency of the tray. Other countries and regions are represented by the United Pallet system established in the country or in the region, and create a special tray shared enterprise, these enterprises in China accounted for a huge share of the market, Pallet system for China’s development provide guidance role, pallet system business to be able to be mature development.The paper study on Tray, tray shared systems, scheduling theory and genetic algorithm theory analysis Pallet system scheduling model focuses on the optimization problem. The purpose of this study is to find the optimal Pallet system scheduling program or strategy to solve the various problems faced by the actual tray operation, Pallet system to improve operational efficiency, reduce the cost of scheduling Pallet.Firstly, by reading a lot of books information, combing the theoretical knowledge of the tray, tray, shared systems and genetic algorithms, as the theoretical basis of this study, reading a lot of literature, research and analysis of the research results of other scholars andreview of the analysis of related research, this study provides references and foreshadowing the role, which creatively put forward the thesis research questions.Secondly, in Chapter3, to establish a system tray under the auspices of the shared service center model, Chapter4considered Pallet system model re-distribution case. Vehicle constraints and transport distance of two factors considered in the establishment of the above mixed integer programming model, In the solution of the model, designed genetic algorithm for this problem, and discuss the application of genetic algorithms algorithms specific solution to solve the problem. Encoding algorithm using a binary encoding of the decision variables, the initial population of200randomly generated selection strategy roulette selection method, set the termination conditions, and ultimately reached the optimal solution.In order to verify the validity of this problem, designed a numerical example. In the part of numerical analysis, analysised the effect of the amount of vehicle car, transport capacity, inventory capacity, handling capacity scheduling decisions.
