【Abstract】 An fuzzy optimization model is established for the flow shop with multiple processors scheduling problem. The presented approach replaces the uncertain parameters with extend expected interval numbers, and establishes approximate boundaries for uncertain parameters during the optimization process. A crisp multi-object programming model is presented. Effects of the variation of decision ratio and uncertainty control constraints are also concerned. Numerical experiment shows efficiency and robustness of the new algorithm.更多还原
