Research On Mechanism Of Coordination In Based-on Multi-Agent Supply Chain

With the globalization of the market, the Supply chain (SC) is facing with more and more challenges and opportunities. Supply chain management (SCM) has been one of the top interests in the field of academia. One of the most important parts of SCM is coordination, which plays the leading role on the operation of SC. Study on coordination in SCM is of great significance in theory and practice. This thesis introduces the theory and technology of multi-agent system into SCM. Special interest is concentrated on the two grades of inventory model including a supplier and a distributor and the mechanism of coordination of task allocation. The main contents of this thesis are as follows: Firstly, the characteristics of SC and multi-agent theory and technology are explained. The possibility of combination multi-agent with SC is described. The architecture of SCM based on multi-agent is also presented. Secondly,a mathematic model is used according to the two grades of inventory problem including a supplier and a distributor. The optimal solution and Nash equilibrium solution of this model is compared. As a result, the coordination mechanism of based-on contract is put forward and illustrated. Thirdly, the characteristics of the task allocation in SC are emphasized. The problems of the task allocation are also described formally. The task allocation is implemented by means of negotiation. The protocol and the algorithms of negotiation are presented, which proves to be effective on cooperation and solving conflicts. At last, the prototypic system of transport task allocation based on negotiation among multi-agent is developed based on JADE, which implements transport task allocation from supplier to distributor in the two grades of providing and delivering model.
