SYSTEM AND METHOD FOR EVALUATING PERFORMANCE OF INFRASTRUCTURE

摘要

Disclosed herein are a system and method for evaluating the performance of infrastructure, in which a condition rating according to a result of a survey targeting experts is expressed as a sequentially distributed probability distribution function using a fuzzy membership function and a comprehensive performance measure score is more accurately expressed as a probability distribution function, thereby accurately evaluating a comprehensive performance measure rating. Also, a utility value is derived using a utility function and usable and functional evaluation measures for each facility of the infrastructure are collected, thereby comprehensively determining subjective performance evaluation measures of the infrastructure.

1. A system for evaluating the performance of infrastructure which comprises roads, railways, harbors, dams, bridges, airports, rivers, water supplies, and fishing ports, the system comprising:
a comprehensive facility performance measure setting unit (110) which selects a comprehensive performance measure for each facility, which is defined according to customer value items preset for each facility of the infrastructure; a facility performance measure setting unit (120) which defines a facility performance measure which quantitatively indicates the comprehensive facility performance measure for each facility of the infrastructure using a fuzzy membership function according to properties of the comprehensive facility performance measure; a facility performance measure utility function determination unit (130) which determines a utility function for each facility performance measure corresponding to an effect value selectively given within a range from 0% to 100% utilizing an expert survey through normalization using a utility theory; a facility performance measure weight determination unit (140) which assigns a weight for each facility performance measure using an analytic hierarchy process (AHP); a facility performance measure evaluation unit (150) which evaluates the facility performance measure utilizing an on-site survey or a check result; a facility performance measure utility function determination unit (160) which determines a utility value for each facility performance measure using the determined facility performance measure utility function and the assigned weight; a facility comprehensive performance measure score calculation unit (170) which calculates a facility comprehensive performance measure score for each facility of the infrastructure; a facility comprehensive performance measure evaluation result analysis unit (180) which analyzes an evaluation result by analyzing an effect of the facility performance measure on the facility comprehensive performance measure score; and an infrastructure performance evaluation unit (190) which performs a comprehensive performance evaluation for each facility of the infrastructure, wherein the facility performance measure setting unit (120) expresses a condition rating according to a result of the expert survey using the fuzzy membership function as a sequentially distributed probability distribution function, and corresponding thereto, the facility comprehensive performance measure is expressed as a probability distribution function in the form of a fuzzy membership function.
