生产设备合作关系网络的建模与分析

区域产业集群中的生产资源能形成多样复杂的合作关系。探讨如何挖掘和利用这些关系来规划和控制集群内部元素的合作,以提供高效的云制造生产服务。采用广义社会合作网络模型描述集群中的制造合作关系,提出构建设备合作网络(FCN)的方法；面向不同的设备选择策略(随机、均衡、带偏好随机及带偏好均衡)设计FCN动态增长过程；基于网络规模、节点度分布、项目度分布和平均最短距离等指标对一个FCN实例的统计特性展开分析,指出均衡策略具有比随机策略更大的网络规模,而随机策略具有较明显的无标度和小世界特性；进而提出基于设备动态加权和子任务集中处理的设备选择优化策略。

Modeling and Analysis on Facilities Collaboration Network

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.
