Evaluation on Industrial Design Scheme of Iron Roughneck Based on TFN-AHP Entropy Weight Method
In order to solve the problems in the evaluation on industrial design scheme of iron roughneck such as strong comprehensiveness,subjectivity and multiple influencing factors,an iron roughneck scheme evaluation model based on the combination of triangular fuzzy number analytical hierarchy process(TFN-AHP)and entropy weight method was proposed.In the model,under the framework of analytical hierarchy process(AHP),based on expert opinions,an evaluation indicator system for industrial design scheme of iron roughneck was built,with the system consisting of 4 Grade-1 indicators and 12 Grade-2 indicators.Then,taking the fuzzy decision matrix as the evaluation information carrier,the triangular fuzzy number(TFN)was introduced to optimize the problem that traditional analytical hierarchy process cannot accurately characterize the evaluation information with fuzzy uncer-tainty characteristics.The objective method,i.e.,the entropy weight method,was used for combination assig-ning to determine the comprehensive weight.Finally,this model was applied in the evaluation of actual iron rough-neck design scheme,the evaluation results were compared with those obtained from relevant traditional methods,and further optimization design was conducted for the selected scheme.The research results effectively assist enter-prises in making decisions regarding industrial design scheme of iron roughneck.
