The DYNWIP control policy is extended for the control of reentrant manufacturing systems. Based on the principles of inventory management, the DYNWIP policy utilizes real-time system information to match production with demand whilst effectively controlling inventory levels. The DYNWIP policy is generally formulated to be applied at all machines of a production line, but this increases the complexity and cost of implementation. Simulation studies show that the application of the policy at a few key machines of a reentrant system is sufficient to generate satisfactory performance. The studies also demonstrate that this new policy performs better than the established CONWIP [11] and WIPLOAD [2] control policies by providing higher service levels with lower work in process (WIP).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
