| Abstract | To remain the competitive, it is impmtant to have the ability to respond quickly and effectively to customer's demand. The system for responding to customer order requests is known as available-to-promise (ATP) system. In an assemble-to-order (A TO), configure-to-order (CTO) and make-to-order (MTO) environment, the last step of putting together a final (customized) product is postponed until a customer-requested configuration can be actually confirmed. For ATP system in A TO/MTO/CTO environment, some researcher proposes an advance ATP system (AA TP) that consists of an integration of push-based planning ATP with pull-based execution ATP to dynamically guide the allocation and reallocation of resources. In this study, the main objective is to develop AA TP system for effectively responding to customer requirement under variability and uncertainties demand in an A TO/MTO/CTO environment. The general AA TP system can be divided into two parts: 1) sales and marketing 2) production planning. For sales and marketing section, ATP checking procedure for responding to customer was developed as a fast procedure. For such case that ATP quantity is not sufficient, a procedure was developed as a decision-making tool that is connected to real-time production planning. For production planning section, the system was developed in two parts: 1) for general pre-allocation base on demand forecast data and 2) for supporting actual customer order in real-time. Dynamic simulation was used to investigate and evaluated the performance of an ATP system. The models are tested and verified before using it in the experiments to generate statistics for the performance measure of the interest. General conclusions regarding conditions are drawn based on the detailed analysis and comparison of the output results. |
