Abstract
This paper addresses the X-factor modeling needs in fab capacity and release rate planning for differentiated manufacturing service provision. A priority X-Factor constrained planning problem is first formulated that describes the relation among profit, release rates of individual priorities, and capacity utilization. Modeling priority X-factors is key to the formulation. We deign a novel M/G/1:PR queue approximation-based network modeling methodology to capture in a scalable way how operation priority, production flow variations, and capacity utilizations may affect individual PXFs of overall fab and tool groups. Numerical studies demonstrate the potential applications of our PXF models.
