This paper shows how to develop a practical finite-capacity planning system for a fabrication factory by expanding an existing Capacity-filtering
algorithm that provides fundamental planning operations under capacity constraints. To achieve this, we represent the fabrication factory’s modeling
requirements and how to logically implement them in accordance with the Capacity-filtering algorithm. As a case study, we developed a Capacity-filtering simulator targeting a TFT-LCD fabrication factory, and the success of the performance evaluation is presented.
