Buffering against uncertainty in high-tech supply chains.
Winter Simulation Conference(2015)
摘要
In this paper we discuss the results of extensive research on supply chain modelling and analysis in high-tech supply chains. We distinguish between the forecast-driven and the customer-order-driven part of the supply chain. For each part we present a generic model that captures real-life complexity of high-tech supply chains. With each model comes a class of operational control policies that coordinate work order release across the supply chain. We discuss the empirical research that shows the validity of the models proposed and the associated class of control policies. We discuss the mathematical tractability of near-optimal control policies based on the fact that optimal control policies within the class of policies proposed satisfy generalized Newsvendor equations. We discuss optimal positioning of quantity and time buffers and issues for further research.
