An efficient production scheduling based on queuing theory in systems with synchronous part transfer during a demand response event

摘要

Due to increased energy costs, manufacturing sectors are investigating viable options to optimize production while minimizing energy costs. Demand response provides one such option to tackle the problems. The objective of this paper is to propose a solution for synchronous part transfer to have higher production rate under demand response available power constraint. To attain our objectives, we first model a synchronous part transfer line using queuing theory to characterize temporal behaviors such as arrival and departure of parts, and utilization of stations (or machines). Then, we propose an efficient scheduling algorithm that provides an optimal schedule taking into account the available power. We also provide illustrating examples and analytical and simulation results to show the performance of the proposed algorithm.
