云制造环境下企业制造资源共享的演化博弈分析

云制造服务平台为在不同时空上获取制造资源提供了一个良好的工作环境,它实现了产品全生命周期的协同制造、管理和创新。在明确云制造环境下企业制造资源共享模式的基础上,构建了考虑两方行为的制造资源共享的演化博弈模型,分别在博弈群体处于均匀混合和非均匀混合两种状态下,找出了模型的均衡点并对其稳定性进行分析。引入系统动力学的方法,建立制造资源共享的演化博弈SD仿真模型,对比分析不同参数变化对演化结果的影响。研究结果表明,企业群体初始共享比例、升级设备成本、信息化改善收益和技术流失风险对博弈双方的策略演化结果具有显著的影响,促进企业联盟中的信息互通与资源共享,须从上述方面着手管理并持续改进。

The Evolutionary Game Analysis of the Sharing of Manufacturing Resource in the Environment of Cloud Manufacturing

The service platform of cloud manufacturing, which provides an efficient operating environment for acquiring the manufacturing resources from different time or space, promotes the collaborative manufacturing, management and innovation in the whole life-cycle of products. Based on the sharing mode of enterprises’ manufacturing resources in the environment of cloud manufacturing, the evolutionary game model of manufacturing resource-sharing to reveal the behaviors between two types of enterprise is constructed; the equilibrium in model and local stability are analyzed in the state of uniform mixed and non-uniform mixed populations. By using the method of system dynamics, the evolutionary game SD model is built, and a contrastive analysis of evolutionary results affected by diverse parametric variations is performed. The research results show that the evolutionary trends are significantly influenced by the initial sharing proportion in enterprise group, the cost of upgrading equipment, the profits of informational improvement and the risk of technological loss. To facilitate the information interaction and resource sharing in enterprise alliance, much advanced management and continuous improvement need to be done in line with the above aspects.
