Abstract
The General Purpose Simulation System (GPSS) was used to model and perform a discrete-event simulation of a large textile finishing mill, producing a variety of woven and knit fabrics for sheeting and men's and women's apparel. This model was validated with actual mill operating data. Simulations were made to determine the effects of market demands, maintenance practices, quality control policies, and total production on equipment and manpower utilization, work-in-process, inventory, and total processing time. For this particular mill, the numbers of dye machines represented the primary bottleneck in increasing mill capacity, and the effect of adding more such machines on capacity was studied in further simulations.
