Research on Evaluation Model of Virtual Training System for Certain Type Power Supply Vehicle
Yue Lu · Jisuanji fangzhen · 2015
Evaluation model is studied for the virtual training system of certain type power supply vehicle,and it is important to judge the operators' operation effectively. The lack of objectivity on assignment of criteria weights may lead to unreasonable evaluation result. To solve this problem,a group decision entropy-fuzzy distance is put forward.The criteria weights are obtained by calculating the expert weights using the decision data of experts. And to decrease fuzziness and randomness of the evaluation,the cloud model is used to obtain the membership degrees of criteria. At last,combined with fuzzy comprehensive evaluation,the cloud-fuzzy comprehensive evaluation model is established and verified through example. The result accords with the actual operation and level of operators and demonstrates the feasibility of the evaluation model.
