Flow Interception Location Problem of Multi-phase and Multi-demand with Changed Network

Abstract

This paper focus on multi-phase and multi-demand location problem, the information of demand and path is different on different time. The decision maker must close some facilities and open some new facilities to match the new demand. Based on the above problem, we refer the multi-phase bi-objective flow interception location model, the decision maker locate the facilities to match different condition, to get the objective of maximized benefit and minimized cost. We design the multiobjective evolutionary algorithm to solve the model.
