工业互联网环境下基于协作度的制造服务组合推荐方法6OA北大核心CSTPCD

Under industrial internet environment,a manufacturing task usually consists of multiple manufacturing services,each of which is not completed independently,and the effectiveness of their collaboration is one of the key factors for success of the service composition.Firstly,based on the number of historical service invocations in the industrial internet platform,the collabo-ration is defined;secondly,the service cost and time measures are improved based on the collaboration;finally,manufacturing service composition recommendation method based on collaboration is proposed and the Non-dominated Sorting Genetic AlgorithmⅡ(NSGA-Ⅱ)is used to recommend the manufacturing service composition scheme with service quality optimization for users.The practicality and effectiveness of this algorithm are verified by comparison with three heuristic algorithms.
