摘要
基于产品保证理论,提出产品保证网络的内涵,分析了产品保证网络的无标度和动态性现象;根据网络演化规则建立模型,通过推导和仿真分析发现:产品保证网络服从无标度分布。其研究结论表明:在产品保证网络中,少数核心企业与其他大量企业具有责任担保关系,在网络中扮演着至关重要的角色,对产品保证以及网络的稳定性和健康发展具有重要影响。
The concept of product warranty network is proposed based on product warranty theory.The paper analyzes the scale-free and the dynamic phenomenon of product warranty network,and establishes an evolving model based on the evolutionary rules of the network.The derivation and simulation demonstrate that product warranty network follows the scale-free distribution.The conclusion shows that in the product warranty network,a few core enterprises has assuring relationships with others,and these core enterprises play a critical role in the network and directly affects the stability and healthy development of the network.
