Multi-objective Location Model Research and Application in the City Emergency Logistics based on Different Product Materials

摘要

We build up a multi-objective location model of emergency logistics center location, The model combined the construction cost of emergency logistics center with the point of shortest distance from the emergency needs of the logistics center to the limited demand, so that meet the different deployment strategies. We get satisfactory results in the practical by using parametric programming method for solving multi-objective model and verifying for the analysis of examples of this multi-objective decision. The model take into account the cost, efficiency and fairness, combined with the traditional model of coverage (covering model, gravity model and the P-median model). To meet the city's emergency different deployment strategy, the multi-objective location model solve and verify by the parametric programming method and some examples.
