| Abstract: |
| Location and allocation analysis is one of the most GIS useful analysis, especially in allocating demands to facilities. One of these facilities is the fire stations, which the correct locations and optimal demand allocations to those have very importance. Each facility has a specific capacity that should be considered in locating the facilities and allocating the demand to those. In recent years, the use of unified models in solving allocation problems is very common because these models can solve a variety of problems, but in most of these models, the capacity criterion for facilities is not considered. The present study tries to investigate the location-allocation problem of fire station with the aid of two Tabu and Genetic algorithms with the objective of maximizing the coverage using the VAOMP model, taking into account the capacity criterion and regardless of it. The results of using two algorithms in problem solving show that the Genetic algorithm produces the better quality solutions over a shorter time. Also, considering the capacity criterion that brings the problem closer to real-world space, in the study area, 59,640 demands will not be covered by any station within a 5 minute radius and will be highly vulnerable to potential hazards. Also, by adding 3 stations to the existing stations and re-allocating, the average of allocated demands with the help of Genetic was 93.39% and 92.74% for the Tabu algorithm. So it is necessary to consider the capacity of the facilities for optimal services. |
