Abstract: There exist complex collaboration relations among production resources in regional enterprise cluster.To achieve efficient cloud manufacturing services,this paper explored how to mine and utilize these relations for controlling the collaboration behaviors.It described the collaboration relations based on generalized social collaboration network,and proposed the method for building Facility Collaboration Network (FCN).It further designed the dynamic growth process of FCN for different facility selection strategies (random,balanced,random with preference and balanced with preference).Based on the metrics such as network scale,degree distribution and average shortest distance,it analyzed the statistical characteristics of an instance of FCN,and stated that balanced strategies possess larger network scale,while random strategies exhibit obvious scale-free and small-world characteristics.At last,it proposed strategies (dynamic weighing of facilities and concentrative processing of successive subtasks) for employing facilities efficiently.
