Multi-grade Fuzzy Comprehensive Evaluation of BOT Projects Service Quality Based on Fuzzy Entropy Weight Coefficient Method

In order to solve the issue concerning the lack of reliable and complete evaluation for BOT (build-operate-transfer) project service quality supervision, a reasonable service quality index system and an effective evaluation method are discussed in this paper. Based on experts interview and literature review, a BOT project service quality index system will be proposed including 3 standards, 9 indexes and 19 indicators. In the construction of our evaluation model, multi-grade fuzzy comprehensive evaluation method is employed as a main evaluation method. Expert subjective weight and entropy method are combined to construct the fuzzy entropy weight coefficient method in order to determine the weight of the index. As a result, BOT projects service quality evaluation model will be proposed and a case of Shajiao B power plant will be provided to illustrate it.
