Fuzzy Comprehensive Evaluation of Machining Process Planning for Green Manufacturing

Given the variety of planning schemes and the elements that influence green manufacturing, a multi-level assessment index system based on five features is developed: machining time, cost of manufacturing, processing quality, resource consumption, and environmental conservation. After that, a fuzzy evaluation approach based on the Hierarchical Entropy Weight is constructed for evaluating process planning schemes. Using modified fuzzy operation principles, the full assessment of multi-process planning schemes is done, and the optimal one is finally determined. Finally, planning plans for vehicle parts are employed in order to validate their feasibility and efficacy of this approach. The results indicate that it is closer in accordance with the actual production and may give the most cost-effective and ecologically friendly processing scheme.
