For solving the large-scale job shop scheduling problems considering flexible routings with the characteristics of process planning and scheduling optimization, a hierarchical coordination optimization model based on analytical target cascading is proposed in this paper, which is divided into three sub-layers. The process planning layer is for optimal processing routes of all jobs, and multiple manufacturing...
Cutter is an important component part of the flexible manufacturing system, so the selection of cutters would have direct effect on the machining efficiency and production cost to the whole system. In this paper, a mathematical model for cutter allocation of CNC machining center in FMS is presented, in which the optimization objective is to minimize the total cost of production. Furthermore, the factors...
For solving service-oriented manufacturing system configuration problems, stackelberg model consist of objective functions which is based on game theory is put forward. The production costs of core enterprises serve as the leader's goal while follower's goal is supplier's profit. To obtain solution of the stackelberg model effectively, double-layer GA algorithm is designed. Apart from that, a numerical...
There are secrets and business of successful software companies explained by Hoch in 2000 and Cusumano in 2004, but there existed none cases from China. This occurred maybe the Chinese software companies are in infancy and the survey is challenge in China. However, the software industry plays an important role in innovation and pushing the economical transformation in China economics. So, in this...
