Abstract
This paper explores the stochastic optimal control problem in a closed-loop hybrid manufacturing-remanufacturing system, which faces random failures while managing greenhouse gas (GHG) emissions. The system consists of two machines—one for manufacturing and one for remanufacturing—producing a single product type. The performance is evaluated by minimizing the total cost, which includes inventory holding, shortage, manufacturing and remanufacturing costs, as well as penalties for exceeding GHG emission limits set by regulations. The goal is to identify optimal production control policies that minimize total costs over an infinite time horizon while adhering to environmental constraints. The study highlights the significance and practicality of incorporating environmental goals, such as GHG reduction and product reuse, into manufacturing system control to help preserve the environment.
In this article, we develop optimal control policies for manufacturing systems within a dynamic stochastic context, considering the greenhouse gas (GHG) emissions produced during the decision-making process. Our goal is to propose optimization models that focus on minimizing the total incurred cost, which includes costs related to the storage of finished products, shortages, production, maintenance, and GHG emissions exceeding regulatory limits.
