AbstractA simulation model of a proposed commercial laundry facility at a cleaning company is built using the simulation package PCMODEL. This model graphically represents the proposed system and is used to determine its operating characteristics, e.g. the average queue lengths, product flows and machine utilization. Data used for the simulation are obtained through informal time studies and from files of historical production data. Based on the results of the simulation, it is observed that the proposed system shows no bottlenecks and the machine utilization is at an acceptable level. This project provides a good learning experience of applying simulation to study operation problems in the service industry.
