Kanalizasyon Sistemlerinde Rehabilitasyonda Öncelikli Bölgelerin PROMETHEE ve MAUT Yöntemleri ile Belirlenmesi

Abstract

Depending on factors such as physical, environmental, hydraulic, and operation in sewage systems, malfunctions such as damage, clogging, collapse, rebound occur and operating conditions deteriorate. The high frequency of these failures causes an increase in system operating costs and local pipe replacement, maintenance and repair costs and decreases the service quality. Therefore, it is important to determine the priority of rehabilitation by considering the factors that may cause failures and structural damages in the sewage systems. In this study, multiple criteria decision-making methods were applied to determine the priority of rehabilitation in sewage systems. For this purpose, weights of factors were calculated using the ENTROPI method based on the field data of 26 factors determined by conducting detailed literature research. Priority areas in rehabilitation were determined according to PROMETHE-2 and MAUT method using factor weights and field data of factors. The weight coefficients calculated with the ENTROPI method were found to be compatible and significant with the natural structure of the problem under study. Using the factor weights and the field data of the factors, it can be said that the priority regions determined according to the PROMETHE-2 and MAUT method, especially the first 5 regions, are generally compatible and show similarity.
