Research on service capacity of production line based on complex weighted network

Production line is a complicated system which comprises many various interacting elements. A complex weighted network model is presented to describe and analyze service capacity of production line in this paper. Manufacturing units are regarded as vertices to denote various resources, such as equipments and workers. The production processes could create directed edges and network topological structure. Network model assigns weight to represent the times of process relationships between vertices. Some feature parameters are defined to characterize the complex statistical properties and uncover the service status of production line. Some important vertices and edges are obtained through analyzing topological properties of complex weight network. Then corresponding controlling strategies are suggested to maintain service capacity of the whole production line. Finally an actual production line as an example is analyzed in this paper to exhibit method and approach of complex weight network of production line.
