A study of resource constraint project scheduling problem for energy saving

摘要

In terms of energy consumption, the environment surrounding the manufacturing industries has become considerably strict. As a framework containing many production scheduling problems in manufacturing industries, a great deal of researches on the resource-constrained project scheduling problem (RCPSP) has been performed. We have proposed a RCPSP formulation called RCPSP/π;RC, which can deal with realistic energy constraints such as power restriction during peak hours, contract demand, and energy consumption during the setup operations. In this paper, we evaluate RCPSP/π;RC through computational experiments. The proposed method is compared with two heuristic rules. Results of computational experiments show the effectiveness of the proposed method.
