Application of the improved fuzzy comprehensive evaluation method in forming processing decision-making for the composite component

The original fuzzy comprehensive evaluation method can be improved and converted to the computer-operable decision-making algorithm which can solve the problem of making the forming processing decision for the aircraft composite component, and the evaluation result is more consistent with actual production. The membership degree calculation method was introduced to determine the evaluation matrix and it achieved the computer instead of manpower to complete determining the evaluation matrix. The increasing safety margin method for the scope of the evaluation was adopted to avoid the problem that dividing the evaluation scope boundaries is too absolute by the original fuzzy comprehensive evaluation method. The dynamic weight distribution method was combined with the ratio method to achieve the computer automatic weight distribution, and it ensured the effective allocation results to meet the user's actual preferences. By using the improved fuzzy comprehensive evaluation method as the core algorithm, the computer aided forming processing design system for the composite component was developed. The developed system was applied in the actual forming processing decision-making, and the decision result was conformed to the actual production. It indicates the feasibility and accuracy of the method in the application of the computer-aided forming processing decision-making.
