High-volume, multistage continuous production flow through a re-entrant factory is modeled through a conservation law for a continuous-density variable on a continuous-production line augmented by a state equation for the speed of the production along the production line. The resulting nonlinear, nonlocal hyperbolic conservation law allows fast and accurate(More)
Model Predictive Control (MPC) is shown to provide a robust, flexible framework to stabilize inventories yet still meet customer demand with minimal safety stock. The translation of available information in the supply chain problem into MPC variables is demonstrated with a two-node supply chain example. A six-node, two-product, three-echelon demand network(More)
On the other hand, the company is a supplier satisfying demand signals from downstream customers. In this role, the manufacturing company warehouses and transports (perhaps relying on subcontractors) a variety of products to a range of geographically disperse consumers. These include other manufactures and their subcontractors, distributors, and end users,(More)
Centralized strategies based on Model Predictive Control (MPC) are applied to inventory management problems associated with semiconductor supply chains. Specifically, two benchmark problems of relevance to semiconductor manufacturing are examined. The first is a single product, two node problem consisting of a Fab/Sort and an Assembly/Test facility(More)
Model Predictive Control (MPC) is presented as a tactical decision module for supply chain management in semiconductor manufacturing. A representative problem which includes distinguishing features of semiconductor manufacturing supply chains, such as material reconfiguration and stochastic product splits, is examined. Fluid analogies are used to model the(More)
Supply chains in semiconductor manufacturing are characterized by integrating dynamics, nonlinearity and high levels of stochasticity. In this paper, we present a novel Model Predictive Control (MPC) algorithm for Supply Chain Management (SCM) in semiconductor manufacturing. A Type II filter is designed to attenuate the integrating noise such as that(More)
