Abstract: To reduce the energy and material consumptions,carbon emissions of job shop by taking energy consumption during equipment operation as the main reason of carbon emission,the carbon emission characteristics of workpiece processing chain was described with improved Gantt chart based on concept of carbon flow rate.To optimize the carbon emission efficiency,the job-shop carbon emission was divided into equipment selection and operation sequence planning two stages,and a two stage low-carbon scheduling model was developed.Based on the developed model,the equipment energy efficiency was improved through optimizing the equipment-workpiece matching relation.Moreover,the comprehensive energy efficiency was enhanced by cutting waiting and idle running time of non-processing equipment.The feasibility of the developed optimized model was analyzed and verified though a certain job-shop manufacturing system.

Key words: job shop, carbon emission rate, carbon emission dynamic characteristic, optimization scheduling
