PT. Indomobil Suzuki International Plant Tambun II is a company who move in four wheel otomotive industry. Process production in painting shop has classified as flowshop type. Section painting is a place for painting white body, to produces car’s body colour and then assembled in assembling shop. Schedule system in painting shop is pari–wari matrix system which based on balanced process time without notices colour groups. It can causes colour change continually at top coat’s painting process. More and more colour change, can causes more setup time because flussing colour, which can be happened if some product admits colour change differently with previous product. The frequency change color also can increases butsu defect if there is overspray, and can decreases quality of painting shop. Because of that, schedule criteria which available for that problem is minimize flowtime and setup time.Schedule method which observer use is Stinson Heuristic which hang on to setup time. To facilitate utility of schedule method, observer also uses software Visual Basic 6.0 to make program application. Result from this method is decrease total setup time at july 14th 1.08 hour, july 15th 1.2 hour, july 16th 1.16 hour, july 17th 1.05 hour, and july 18th 0.97 hour. From comparison of pari–wari matrix system and proposal of stinson heuristic which selected is stinson heuristic method because it has minimum total setup time on third week at july 2008.Furthermore, observer does simulation with software Promodel 4.22 at production system in painting shop to increase performance with utility criteria, flow time, the amount of WIP, output number. It has four alternative of proposal, first proposal of simulation using first production layout and schedule method has produced flowtime 14.68 hours, WIP 235 units and output 47 units. Second proposal of simulation not using storage IC and schedule method has produced flowtime 14.6 hours, WIP 232 units, and output 49 units. Third proposal of simulation using production layout and gathering process of UDC and PVC and schedule method has produced flowtime 14.62 hours, WIP 230 units, and output 49 units. Fourth proposal of simulation gathering second proposal and third proposal and schedule method has produced flowtime 14.55 hours, WIP 228 units, and output 51 units. Based on comparison of four simulations, which selected is fourth proposal because it has large utility, minimum WIP number, minimum flow time, and large ouput number so it can increase performance in painting shop.
