Modeling and solving the problemof locating bi-objective allocation inhumanitarian logistics with regard tourban infrastructure
Crises are the inevitable realities of human life; which is an accident that occurs naturally or suddenly orincreasingly by human and to address it, there is a need for urgent and fundamental measures. When thecrisis occurs, pre-determined storage locations will play an important role in relief; therefore, the selection ofsuitable places for warehouses is one of our main goals in this research. In this research, a bi-objective linearprograming model with integer variables is developed. The proposed model attempt to minimize total costalong with maximizing the minimum weight of open shelter areas while deciding on the location of shelter areas,the assigned population points to each open shelter area and controls the utilization of open shelter areas.In order to solve proposed model, some of well-known multi-objective, exact methods include a weightedsum method, LP-metric method, and goal programing approach are employed. Finally, the best open shelterareas with considering the minimum cost is obtained, which these results can be useful for crisis organizations.
