Optimizing Designs to Improve the Blockage Behavior of Emergency Networks

摘要

For transport networks, communication networks, and especially emergency evacuation networks, moving objects tend to be not very obedient to any law. Each flow is stochastic and uncontrollable. We may fail to reach a maximum flow and get an undesired maximal flow, which is called a saturated flow. This reflects on how inefficiently the network is utilized. Therefore it is important to consider the values of the saturated flows in the process of designing the network. In this paper a model for optimizing designs is proposed to improve the blockage behavior of originally designed networks. Three network examples are chosen to illustrate the optimization procedure. Results show the rationality and feasibility of optimization designs.
