Study Of The Theory And The Application Of The Fourth Party Logistics

Recently, that the development of informationalization and economic globalization has expanded the space of logistic operation requires a new role who plays "an integrated management" between the traditional vendors, the manufacturers, and the third party logistics (3PL) service providers. The notion of the fourth party logistics (4PL) is the outcome of the integrated management style which is executed in the phase of the global logistical planning management. Studying on the fourth party logistics is helpful to instruct the reforming of industrial and the commercial corporations and the logistic corporations, integrating the logistic resources in our country and developing the logistic industry healthily.The thesis is to widely elaborate the theory about 4PL, deeply analyze the inner meaning of it and the difference between 4PL, 3PL, 2PL and 1PL, and bring forward the operational model of 4PL.Furtherly, the transportation model and assignment mode is constructed . Toward the transportation model, firstly under the consideration of time windows, the routing optimization is implemented by genetic algorithm. Then the model is developed into a linear programming transportation problem and can be computed easily. Toward the assignment problem, the third party logistics companies are selected by the matrix of "efficiency" which is used to evaluate the matching of the companies and jobs. According to the analysis of the situation of a China and the relationship of 4PL and the traditional logistical corporations the countermeasures on the development of the fourth logistics in our country is figured out by an analytic tool —SWOT. The last part is to give an empirical analysis about the fourth party logistics operation with the example of Annto Supply Chain Technology Co., Ltd.The following fruits and conclusions can be attained through the above jobs:1. As the organizer, the fourth party logistics should take on the responsibility of synthesizing logistics management and supply omni-directional and one-stop services.2. The relationship of 4PL and 3PL is symbiotic.3. Developing the fourth party logistics in our country, there is strength andopportunity, and the weakness and threat also exist. The government should exert the administrative function and take the effective measures and strategy.
