Abstract: The energy consumption of machining workshop includes not only the direct electrical energy of machine tools consumed in the machining process but also the indirect energy consumption resulting from the use of auxiliary resources such as tool,coolant.Due to the viable alternative of process routes and processing resources for processing tasks in the flexible job shop,the scheduling schemes are highly flexible and have great potential for energy saving.Therefore,a flexible job shop scheduling optimization model for generalized energy which considered the direct electrical energy and indirect energy consumption was proposed.The direct electrical energy and indirect energy of flexible job shop scheduling was analyzed and then the flexible job shop scheduling multi-objective optimization model was established to minimize generalized energy consumption and makespan.The model was solved based on Multi-objective Simulated Annealing algorithm (MOSA).Through the comparative analysis of practical cases,the validity of the proposed model was verified.
