Improve the Performance of the Fuzzy Priority Queue in Baghdad Teaching Hospital

Abstract

This research included the creation of membership functions for the standards of performance in the queue system for three priorities, as both access rates and service rate are fuzzy numbers. The DSW (Dong, Shah and Wong) algorithm was used which is based on the α-cuts approach and the extension principle of (zadeh) for fuzzy sets. The DSW algorithm in turn included ambiguous values as upper and lower limits for each of the system performance metrics by using mathematical parametric programming.The study summarizes a set of findings and conclusions because of the many problems for patients waiting at the Baghdad Teaching Hospital / Department of internal medicine. System performance metrics were found through the DSW algorithm for model (FM/FMi/1):(∞ / FCFS-Priority ordering) according to the order of priority.
