Design of complex mechanical equipment and scheme of manufacturing need a comprehensive consideration of constraints, and it embodies multiple layers, complexity, multiple types and uncertainty. This paper analyzes the question of scheme optimization for complex mechanical equipment and proposes a method of manufacturing scheme optimization for complex mechanical equipment based on multi -attribute fuzzy information measurement model. This method functions to build an indicator system of optimization scheme for manufacturing complex mechanical equipment. Three models are designed to evaluate all optimization indicators the system, namely model for computation of fuzzy interval indicator’s information quantity, model for computation of qualitative indicator information quantity and model for computation of fuzzy indicator’s information quantity with degree of membership. Weights are given to information quantity optimization indicators in different layers get total complex mechanical equipment scheme choose optimal strategy based on design manufacture.
