Abstract: Throgugh expounding the structure and optimization goal of an enterprise value chain,the paper analyzes the necessity of using fuzzy programming model for value chain optimization,sets up the fuzzy linear programmer model of an enterprise value chain optimization.Finally it gives a numerical value calculating example and outcome analysis as an example of saloon enterprises.The utility of this method is proved in terms of aplying research in an enterprise value chain optimization.

Key words: fuzzy linear programming, value chain optimization, uncertainty, core competitive advantage, customer value
