| Popis: | This paper proposes a capacity planning system CPS to determine the capacity of machines and kits in integrated circuit final test plants. CPS applies the concept of workload levelling and infinite capacity planning on dual resources. CPS consists of four modules: Work-in-Process WIP-Pulling Module WPM, Lot Release Module LRM, Workload Accumulation Module WAM and Workload Balance Module WBM. The WPM pulls WIP from the end of the process route to meet the master production schedule MPS. If WIP cannot meet the MPS requirement, LRM is executed. WAM simultaneously accumulates the workload to conduct an IC final test machine and kit on a daily basis. WBM levels the loading of machines and kits by adjusting the lot starting time with the use of these resources. CPS is developed in Microsoft Visual Basic, and industrial data are used to test its performance. The experimental design includes four factors: workload balance heuristics, MPS variation, MPS variation frequency and product mix. The simulation results are analysed by using descriptive statistics and ANOVA. The results show that CPS is effective and efficient in balancing the workload of resources, including machines and kits. |
