Abstract

The design of assembly lines for production operation is deemed crucial to ensure optimal productivity and minimal work in progress. A case study involving investigation of manufacturing assembly line is to be considered for computer based modeling using WITNESS. The objective of this project is to model a manufacturing assembly line for 3 pin power plug using WITNESS and to conduct a sensitivity analysis that would improve the production capability and output rate. The scope of the project is to conduct the corresponding time study for manufacturing assembly line of 3 pin power plug assembly including setup time and operation time. To conduct a simulation project using WITNESS, there are several phases that to be concerned. The phases are established objectives, scope and level of model details, data collection, structuring the model, building the model, testing the model, experimentation, documentation, presentation of result and implementation. The simulation result for manual assembly shows that the number of finished product is 1332 pieces of 3 pin power plug in per day. The total time taken for manual assembly for a 3 pin power plug is 43.2 sec (including handling time and insertion time). The throughput time is 0.72 per minute. The time taken to insert the part by using single station with one arm is 22 second while using two arms it's just required 9 seconds. The throughput time for single station with one arm robot is 0.46 minute per pieces and for two arms is 0.25 minute per pieces. The result from simulation shows great increased on the number of part produces when we introduce automated assembly. In single station with one arm robot, 2085 pieces produces in daily. The production of the plug increased double if compared with manual assembly. While the double arm robot can produces 3839 pieces of power plug daily. From the result, it shows that the single station system with two robot arm yield the best results. It can be concluded that WITNESS is among one of the powerful tools to do a simulation for assembly lines. Therefore further exploration on how to use the software should be enhanced in order to fully utilize the benefit and capability of the simulation
