Combine cost and time satisfaction into a multi-objective programming for integrated logistics system

This paper focuses on the optimization of location inventory routing problem (LIRP) taking the retailers' customer time satisfaction degree into account. Based on the model of LIRP, a multi-objective programming model of LIRP which accounting to customer time satisfaction degree is built. Then an improved genetic algorithm is introduced to solve the model. Finally, a set of computational experiments are conducted, the results show that the model is suitable and the method is available.
