İnsani yardım lojistiğinde model yaklaşımı: bir İstanbul depremi sonrası sıcak yemek dağıtımı

In today's world, disasters occurring around the world in different types are still the most important factor disrupting the continuity in the development of our community. Disasters, while reasoning loss of lives, affect the human life both on the economic level and life standards in negative manner. Our country stated at a risky place for earthquakes especially for the most probable Istanbul earthquake. The earthquakes occurred in recent years, and the actions taken after all, ensured to raise situational awareness on the issues like developing new models to improve the resilience in the community, enhancing the capacity building actions, taking the precautions for mitigating the disruptive affects of disasters. In this study, for improving the functionalities of Turkish Disaster Response Plan, which enlarges the area on developing new models on preparedness and response, enables to perform capacity building actions. A MDSDLRP (Multi Depot Split Delivery Location Routing Problem) model with capacitated depots with homogeneous fleet type and without fixed facility location costs with the minimization of longest travel time objective proposed for the hot meal delivery aftermath of an earthquake. Considering the interdependency of the three sub-problems (location-assignment-routing) a Two Step Heuristic Approach including split and merge clustering with iterative boundary and genetic algorithm is used to solve the problem. The case study includes the real disaster assembly areas and the expected demand of those regions regarding the scenario based percentage of affected people for the European side of Istanbul.
