基于SQP法的泵站建筑物模糊安全综合评价及界面开发
SQP method-based fuzzy comprehensive safety assessment on pumping station structure and its interface development
摘要
Abstract
Aiming at the problem of that the calculation precision is less accurate,which is caused by the separation of both the weight calculation in the analytic hierarchy process (AHP) and the consistency of the judgment matrix at present,a SQP method-based algorithm is put forward herein.Meanwhile,for the problem of that the number of the indexes in the safety assessment of the structure of pumping station is much more,and then the calculation is complicated and errors are prone to occur,the whole safety assessment process is designed into a visualized interface on the basis of MATLAB GUI.The weight calculation is integrated with the judgment matrix consistency test,thus forms a nonlinear optimization problem,which is then solved with SQP method.The calculation process is encapsulated into an interface with MQATLAB GUI by integrating the fuzzy comprehensive assessment model together based on the proposed algorithm for the SQP weight calculation.By taking the safety assessment made on a pumping station structure of the Large I type of the East Route of the South-to-North Water Transfer Project as the study case,the weight values of all the indexes of the pumping station are calculated with the SQP algorithm.The calculation result shows that the precision of the algorithm is high with a fast convergence speed.The safety assessment can be simply and quickly completed through applying the developed interface to this pumping station,from which the result is more coincided with that of the actual status.The study result can provide reference for the similar structures,such as pumping station,etc.关键词
