Reliability based topology optimization design of the network system: A case study on a sewage treatment system

The network topological optimization, developing the scheme of pipelined connections needs to find the best layout of all links in the urban sewage system, makes the whole system cost-effective with the satisfaction of some special criteria. In this paper, the application of constraints based on some priori knowledge, including the requirement to link the components in network systems, reduces the solution space of the optimization substantially, unlike most literatures focus on improving the efficiency of optimization algorithms through the modification of the algorithm itself. In order to evaluate it, the network topological optimization of a sewage system, serving two different cities, is investigated. Performance of the solution based on the application of priori knowledge is validated through the sewage system. It indicates that the application of priori knowledge can be efficient for the solution.
