Fuzzy decision modeling for manufacturability evaluation under the concurrent engineering environment

A manufacturability evaluation decision model is formulated and analyzed based on fuzzy logic and multiple attribute decision-making under the concurrent engineering environment. Multiple criteria such as the goal space, the decision space, the function space, the development (i.e., product and process design) space, and activity space, are then applied under different analysis of decision-making methods. The fuzzy multiple attribute decision-making (FMADM), combined with activity-based costing (ABC) can be used in the activity decision space. And the fuzzy logic decision model can be applied in the goal decision space. The results of the study point out the importance of early decision making capability. An example of a high-pressure vessel is provided to demonstrate the proposed model for evaluating the manufacturability
