Study on Extensional Evaluation of Excavation Engineering Project Management Performance on OWA Operator

In order to evaluate the performance of excavation engineering project effectively and discuss the scientific performance evaluation method of engineering project management, this paper built index system of foundation pit engineering project management performance evaluation, and on this basis, OWA method was used to empower the evaluation index for improving the objectivity of the evaluation results, and through the calculation of various evaluation indexes about the correlation of evaluation grades and characteristic values of evaluation grades by the matter element analysis method, this paper converted multi-objective evaluation into single objective evaluation, and evaluated the performance of excavation engineering project from the perspective of quantitative aspect, and the example analysis was used to verify that the evaluation of the performance of excavation engineering project is feasible and practical by the OWA operator and matter element analysis method.
