EFFECTIVE INSPECTION OF SPARSELY LOCATED WATER SUPPLY FACILITIES WITH VARIOUS INSPECTION PERIODS

Abstract

Sparsely located small water supply facilities are regularly inspected by maintenance patrols. Effective patrol strategy for facilities with different inspection periods, namely, every day, every two days and every 4 days, were investigated. An optimization model was formulated in which the patrol days for all facilities and optimal patrol root for each day should be determined with the objective of minimizing total patrol time. Use of automatic analyzers was also examined in order to reduce inspection cost. Case study was carried out and the developed method was verified.
