| The construction of Pingwei ultra-supercritical coal-fired generating units (Pingwei 5#) is the only UHV transmission lines for 1000MW of power projects in Anhui and it has significant influences on the power development in China. The constructions of this power plants is different from general construction work due to high cost, high risks and so on. Meanwhile, there is a large number of new materials and new technologies used in this project, which can lead to the difficulties in safe construction, so how to carry out the work safely is very important for the constructions of this power plants,In this paper, a method named Fuzzy Comprehensive Evaluation (FCE) which combines Analytic Hierarchy Process (AHP) with Fuzzy mathematics is presented based on referring to domestic and international literatures, then the FCE is used to assess the safety management of the construction of Pingwei 5#. Firstly, after survey on site and the analyses of a number of factors effected on safety management for Pingwei 5# construction project, the comprehensive evaluation index is selected to set up an evaluation system. Secondly, according to AHP theory, this paper build the different levels of evaluation judgment matrix, then determine the weight of various indicators and check the consistency of matrix. Next, based on the fuzzy mathematics, fuzzy relation matrix determined by experts scoring and comprehensive evaluation results calculated by the fuzzy algorithm. Finally, combined with matching applied computing program, this evaluation method can obtain an fuzzy comprehensive evaluation results about Pingwei 5# unit construction.The fuzzy comprehensive evaluation model constructed by this paper can improve the safety management of construction projects and have some directive impacts for the same constructions. |
