The developed FCMRP system has two\r\nmain stages. The first stage is to allocate operations to the first and\r\nsecond priority work centers and also determine the sequence of the\r\noperations on each work center. The second stage is to determine the\r\noptimal start time of each operation by using a linear programming\r\nmodel. Real data from a factory is used to analyze and evaluate the\r\neffectiveness of the proposed FCMRP system and also to guarantee a\r\npractical solution to the user. There are five performance measures,\r\nnamely, the total tardiness, the number of tardy orders, the total\r\nearliness, the number of early orders, and the average flow-time. The\r\nproposed FCMRP system offers an adjustable solution which is a\r\ncompromised solution among the conflicting performance measures.\r\nThe user can adjust the weight of each performance measure to\r\nobtain the desired performance. The result shows that the combination\r\nof FCMRP NP3 and EDD outperforms other combinations\r\nin term of overall performance index. The calculation time for the\r\nproposed FCMRP system is about 10 minutes which is practical for\r\nthe planners of the factory.","references":null,"publisher":"World Academy of Science, Engineering and Technology","index":"Open Science Index 46, 2010"}
