| Abstract | This study proposes an Available to Promise (ATP) system to satisfy the customers and requirements effectively. The proposed ATP system (PATP) attempts to reach specific decisions such as to accept or reject an order and to determine order quantity and order due date considering resources allocations. The P ATP system is developed for multiple products with multiple processes, parallel machines and real time response. The PA TP system applies the (ollowing rules in making decisions. First Come First Serve (FCFS) rule is applied to allocate finished good resources, linear programming model is used for the allocation of components resources and modified Giffler & Thompson algorithm is used to allocate machines resources. The PA TP was compared with an existing pull based ATP model known as Real Time Order Promising and Scheduling (RTPS) system to evaluate performance of PATP system. The inventory allocation procedures of PATP system and RTPS system do not affect the performance of ATP systems since one order at a-time with FCFS are applied in this study. Therefore, the performance of the ATP system only depends machine allocation. Modified Giffler & Thompson algorithm was compared with scheduling algorithm of RTPS system called RTP algorithm. Two cases with different customer decision requirements are used as basis for the test problems. First case is concerned with the case when customers always accept the factory due date and second case is when the customers always reject the orders beyond customer due date Test problems were executed to observe the effect of the algorithms and to compare the· performance of the algorithms. The performance of modified Giffler & Thompson and RTP algorithms are measured by mean tardiness and number of lost order. The result shows that PATP provides significantly better result compared with RTPS system in terms of mean tardiness and number of lost order. |
