Function Effects Post-Evaluation for Substation Construction Project Based on Multi-Level Extension Assessment Method

Abstract

This paper established a multi-level extension model for function effects post-evaluation of substation construction project, the model not only reduces the influence of subjective factors on the evaluation results, but also can determines the key factors which affect the quality of the evaluation results and overall developing trend of the project and provides some suggestions for the project late operation. Taking into account the fact that the element of the judgment matrix formed by traditional AHP is a certain value and may lead to a big difference from the judgment matrix formed by the different group of experts, thus reduces the credibility of the evaluation results; In order to overcome the problem, this paper introduces the concept of interval number, the maximum and minimum of judgment matrix elements relative importance comparison are used as the upper and lower limits of interval number respectively. Interval number are used as the elements of judgment matrix to make the evaluation result more rational. At the end, a practical 220kV substation construction project is taken as an example to verify the validity and rationality of the established model.

A Survey on Post-Evaluation Indicator System for Multi-Energy Infrastructure Investments

“…Thus, both the characteristics of the current point and the evaluation of future development need to be considered in the sustainability postevaluation indicator system to ensure continuous evaluation [11], [18], [27]. The internal conditions reflect the financial operational level, the advanced nature of technique level, the level of management system, enterprise competitiveness, primary energy ratio (PER), relative energy saving rate (RESR) and security [11], [34], [56], [61]. The external conditions, considering the impact of economic development social environment and other external factors, are to enhance the ability of a project to maintain a high service level and operating ability, and improve the comprehensiveness and accuracy of the evaluation results [24], [29], [32].…”
