摘　　要：针对多品种混流生产线的产能规划问题,通过建立混流生产线的有向加权网络模型,直观地描述各个工位之间的工艺关系。以混流生产线的稳定性为前提,根据网络的拓扑性能,判断网络的运行状态,寻找关键节点并规划其能力冗余和资源配置,以避免偶然失效带来的整个生产线的灾难性后果。以真实生产线为实例,根据网络所表现出的小世界特性,通过对具有较高节点度的工位进行负荷控制,完成了生产线的产能规划。Facing to capacity planning for mixed production line which is a complicated problem,a directed weighted network was constructed to describe the complex processing relationships among working stations.Anyway the stability of mixed production line is the most important problem for capacity planning.Therefore the whole status and the key vertices should be obtained by means of topological characteristics of network architecture.And then the capacity redundancy and resources configuration will be planned in order to avoid the catastrophic failure of the whole production line due to accidental disable of vertices.Finally,an actual production was introduced as an example.According to the small-world property shown in the network,the capacity is planned through controlling the working load of those vertices with high degree.
