Abstract: To comply with the need of competition in the era of knowledge-dominated 21st century, appears advanced manufacturing model of virtual enterprises in manufacture industry,which makes the study on virtual enterprise as one of hot topics in academy.At present,the study on partners selection of virtual enterprises focuses in the selection as constructing virtual enterprise,it is a tacit selection,which is unfit for the "agile" characteristic of virtual enterprises.Because of the intangibleness,spillover,non-terrain of knowledge and competitive collaboration among partners,intellectual assets conflict will happen in virtual enterprise inevitably,which give rise to the dynamic iteration of partners in virtual enterprise.Therefore,based on the minds of Simulated Annealing Algorithm,the article designs an algorithm to resolve dynamic selection for the members in dynamic alliance,the algorithm solves the question how to select and eliminate the members in virtual enterprise well,the case indicates that the algorithm is fit to the operation in fact.Of course,when applying simulated annealing algorithm,there some new problems which should be studied further.

Key words: virtual enterprise, intellectual assets conflict, simulated annealing algorithm
