Location Allocation of Earthquake Relief Centers in Yazd City Based on Whale Optimization Algorithm

Despite the fact that many governments try to set rules guarantee having resistant buildings, there are vulnerable structures in world. Hence, establishing earthquake relief centers is an important issue order control effect of earthquake. Iran a country middle east which severely against Yazd central city Iran. Since no such study for city, this considered study.  The parcels' layer GIS map has been used as input problem. location allocation problem with huge complexity and cannot be solved polynomial time, Whale Optimization Algorithm (WOA) solve or WOA particle based heuristic algorithm suitable solving hard problems. main contributions research modifying function designing new method creating whales. In reduce time reaching reasonable solution innovative whale generating been  designed.  results show average distance each parcel from its center 1541 meters standard deviation 114
