Abstract: Focusing on cloud manufacturing-oriented job shops,the protective capacity of machines for self-manufacturing and cloud service capacity of machines for cloud service capacity were studied  under different disturbed production environment.The chang law of  throughput of manufacturing system with the increase of machine capacity was analyzed.The concepts of capacity slack rate of activation and available scheduling capacity were presented,and a capacity partition model of machinese in cloud manufacturing-oriented job shops was established.The capacity utilization of non-bottlenecks was increased gradually to find a curve showing the relation between non-bottleneck slack rate and production system performance under different production conditions through setting different non-bottleneck capacity slack rates and disturbance levels.A capacity partition method of non-bottleneck based on clustering algorithm was put forward.The productive capacity,protective capacity and cloud service capacity of each non-bottleneck machine under different disturbance were determined,which provided a decision-making basis of capacity partition and utilization for self-manufacturing and cloud manufacturing of enterprises.
