Study On The Regional Third-party Steel Distribution System Based On Multi-agent Theory

Modern logistics process due to the cash flow, business flow, information flow between the asymmetry caused by the delay, because of the emergence of electronic commerce are well solved. In order to further speed up the modernization of logistics distribution of shipbuilding industry, taking yangzhou as an example is constructed to jiangdu ship agglomeration zone third party ship steel distribution system, the service object is mainly around the small and medium-sized shipbuilding enterprises, private shipyards steel suppliers and repairing yard, small and medium-sized shipping companies such as coordinate, the small and medium-sized steel pretreatment line of the shipbuilding enterprise forward, at the same time shipping enterprises of steel shear processing equipment investment costs have been reduced, steel supply enterprise product line extension, and ship manufacturing iron and steel enterprise get promote the exchange of information, ship steel transparency of supply chain management is enhanced.Agent technology as computer software in recent years, with the popular research object in the field of distributed artificial intelligence, Multi-Agent system with its high degree of openness, good collaborative, simple design, wide adaptability, easy to reconstruction and rapid reactive characteristics and is very suitable for Marine steel distribution steel distribution system to build a third party. This article first to the Marine steel distribution system, Agent technology, Multi-Agent system are introduced, using ant colony algorithm is a Marine steel distribution center in yangzhou distribution area of the planning, on the basis of the presented based on Multi-Agent of yangzhou third-party ship steel distribution system architecture, and expounds the implementation technology of Multi-Agent system platform,including the communication and cooperation mechanism between the Agent and the contract net protocol, JADE, JADE development platform to build the Agent class library, etc.Yangzhou a third-party ship steel distribution system construction, also need to consider the upstream steel products supplier of choice. When the number of steel suppliers is less and less evaluation index, can make use of the analytic hierarchy process to design the steel supplier selection system based on Multi-Agent the general structure, the evaluation index system and evaluation method. For steel mills are too many as the number of steel suppliers, choose the consultation process using multi Agent system modeling, combining the supplier evaluation and risk control of supply and demand under the optimal number of suppliers of decision problem, and considering the influence of policy makers to steel supplier selection.
