Integrated optimal production and energy control of a single machine and single product-type manufacturing system

Reduction of energy consumption has attracted much attention of the researchers and practitioners in the field of sustainable manufacturing. However, the issue of integrated optimal production and energy control for sustainable manufacturing systems has not yet been investigated sufficiently. In this paper, we study such a problem for a single machine and single product-type manufacturing system, with the objective of minimizing the sum of production cost and energy consumption cost. To solve this problem, a Markov decision process model is developed, based on which, we obtain the integrated optimal production and energy control policy by the policy iteration method. Furthermore, we reveal the structural characteristics of optimal control policy and analyze the influence of system parameters on it by comparing different cases.
