Abstract. The operative management of jobs in semiconductor fabrication plants (FABs) is highly challenging due to the complexity and scale of their processes. Inefficiencies in a FAB can disrupt the entire supply chain, increase production costs, and cause financial losses for downstream industries. This paper focuses on the Process Capacity Planning problem by proposing a novel approach that integrates with existing practices at ST. The method combines a Mixed Integer Linear Programming Model (MILP) with the FAB’s Digital Twin (DT), enhancing the robustness and adaptability of the MILP-generated solution. Numerical validation is conducted on instances derived from the industrial case.
