Abstract—The burgeoning technology of manufacturing grid provides the impossibility to share manufacturing resource over Web. Taking sharing the cost equipments as the objective, CNC resources grid is a sub category of manufacturing grid, which is facing with the difficulty of scheduling optimization. This research is divided into three parts. First, the elementary model for CNC grid is proposed and some assumptions are given, based which the differences between the CNC grid schedule and traditional schedule are detailed. Second, the selection strategy and algorithm are proposed based on the analysis of the CNC nodes features. Finally, a schedule system for CNC grid is developed and the contrastive experiences are done, which demonstrate the advantages of the novel tactics and algorithm, and the scope of application of the novel methodology.

Index Terms—manufacturing grid, resource sharing, networked manufacturing, constraint satisfaction problem, schedule optimization.
