Research on Emergency Material Storage Facility Location Problem of Guangdong Province

In this paper, the problem of emergency facility location is studied. Adopting the location method of generalized maximal covering model, the study describes the coverage level of emergency facility as a piecewise function decreasing with distance. The study analyzes and quantifies influential factors for the location of emergency material storage facility, such as affected population, economic importance, and total mileage density. Based on setting weights on each factor, a mathematical model for emergency facility location problem is proposed, with the shortest distance from emergency facility to its coverage area as the objective function. Therefore, the coverage level of the selected emergency facility can be maximized with the discussed constraints. Finally, the operational research software helps to calculate the model and realizes the optimal solution of the emergency facility location and its coverage area in Guangdong Province. This model provides an effective analysis method for emergency facilities location problem.
