Multi-objective group decision method for crowdsourcing product modeling design scheme in cloud environment

Aiming at the decision problems in the manufacturing process of crowdsourcing product modeling design schemes in the cloud environment, a multi-objective group decision method was proposed from the perspective of industrial design. The characteristics of the crowdsourcing product modeling design and manufacturing process in the cloud environment were analyzed, by taking the existing crowdsourcing product modeling design schemes as the research object. The evaluation objectives that need to be considered in the process of group decision was analyzed according to the characteristics of the schemes. The evaluation objectives and objective weights were calculated by using the analytic hierarchy process, and the multi-objective evaluation system for the crowdsourcing design was established. The multi-objective group decision-making problem was transformed into multi-objective optimization problem. The multi-objective group decision model for the crowdsourcing product modeling design was constructed based on the evaluation system. The optimization method was used to solve the model, and the crowdsourcing design scheme which was closest to the idealized scheme was obtained. The decision problem of crowdsourcing product modeling design scheme for the medical analgesic pump was taken as an example, and results show that the proposed method can effectively solve the group selection and decision-making problem of crowdsourcing product modeling design scheme in the manufacturing process.
