Abstract


, Logistics has become the focus of attention to improve the competitiveness of the manufacturing sector to reduce the cost of growing demand. Fourth Party Logistics is in this context. Fourth party logistics research is still in the exploratory stage, in its definition, the concept of the mode of operation and other aspects have not yet unified understanding, and argument. This article by a fully integrated fourth party logistics research results have been combined with the actual project - \In this paper, a fourth party logistics information system structure based on Multi-Agent structure, and analysis of the basic functions of which each agent. Therefore, the fourth party logistics suppliers in the whole system is the core and key a fourth party logistics decision support system framework and analysis of the key issues - the design and optimization of logistics solutions. For this key issue, the paper established a \The logistics optimization process. Due to the presence of the customer needs (ie constraints), we designed a double traversal process to simplify the logistics network established, aimed at reducing the next step to optimize the amount of computation. Logistics solutions for the optimization problem, described as \And designed a \Although A ~~ * algorithm essentially does not solve the \performance. The final step in the optimization 3PL evaluation and selection of suppliers, and the Analytic Hierarchy Process (AHP) and data envelopment analysis (DEA) are two commonly used method of vendor assessment. In this paper, the advantages of each of these two methods, design AHP / DEA method to select 3PL suppliers, and a simple example is given. The paper analyzed at the end of the fourth party logistics optimization module in the need to pay attention to the specific implementation issues, mainly two aspects of logistics information collection and sorting and optimization module technology. Finally, some of the problems encountered in the study, and put forward a few suggestions for improvement.
