Applied Research Of Extension Mathematical Approach In The Supply Chain Management

With the development of network technology and economy globalization, large and medium sized enterprises establish dynamic alliance between their suppliers and distributors worldwide. In this operation environment, the supply chain management model, supplier evaluation and enterprise reorganizing to solve.The creation in this paper is we use the ideology of extensics on the the analysis of hiberarchy, it lead to the more clear logic and more precise framework, then through the definition of extension space and the present of association function, we finish the test of consistency of extension interval number judgement matrix of AHP., then build the perfect Exntension AHP structure. It is also used into a supplier evaluating index system of Supply Chain Management (SCM), and we obtain satisfied improvements. In the meanwhile, we also use the ideology of extenics into enterprise reorganizing, then instruct this strategy which solve the problem of resource's comparatively overplus and comparatively shortage.In the end of the paper we get the conclusion, extension mathematics prepare basic theory for ambivalent problem which may appear in AHP, then it also build a bridge between impersonal world where there are inconsistent problems andmathematics.
