Abstract: Today, variability in different domains of manufacturing systems like demand, leads to unreliable customer services, unbalanced shop loads and manufacturing lead times. In order to meet demand variability and incorporate the changes of variability, hence improving the high levels of system performance, it becomes necessary to study the different parameters of variability. This helps to improve several criteria like machine utilisation, labour output, bottleneck detection and reduction, etc. in turn meeting the quality parameters in terms of quality, cost and delivery time. This paper considers a job shop to examine the effects of variability conditions on various factors. Simulation is adapted as tool and results indicate that shop performance measures are affected by demand variability parameters. Automobile service centre is considered as the job shop for studying the effects of demand variability.

Keywords: job shop system; simulation; demand variability; automobile service centre; ASC.
