Deprem Sonrası Toplanma Alanlarına İçilebilir Su Dağııtım Problemi

Amaç: Çalışmanın amacı, belirlenen bir bölgede toplanma alanlarına en son varış süresini en aza indirmektir. Ele alınan bu problem için yeni matematiksel model önerilmiştir. Bölgede, deprem sonucu oluşabilecek dört farklı senaryo dikkate alınarak her bir senaryo altında içme suyu dağıtımı için en uygun plan oluşturulmuştur.Yöntem: Çalışmada, araç rotalama problemi ele alınmıştır. Araç rotalama probleminin çözümünde genellikle optimizasyon teknikleri kullanılmaktadır. Optimizasyon, belirli koşullar kısıtlar altında karar vericinin amacına yönelik, “en iyiyi aramak” olarak ifade edilmektedir. Böylece, araç rotalama problemi için “en uygun rotayı bulma” ifadesi kullanılabilmektedir. Bu çalışmada, optimizasyon tekniklerinden biri olan matematiksel modelleme yaklaşımı kullanılarak, karar vericiler için toplanma alanlarına en son varış süresini en aza indirmeyi sağlayan en iyi rota önerilmiştir.Bulgular: Çalışma kapsamında, deprem sonrası oluşabilecek farklı hasar düzeyleri, Sakarya için farklı senaryolarda incelenmiştir. Deprem sonrası meydana The latest arrival times to assembly areas increase as the damage that may occur after the earthquake increases. The arrival times to the assembly areas are also different according to scenarios, because the optimum routes change for these scenarios.Conclusion: In this study, the drinking water distribution problem to assembly area is handled. The proposed mathematical model is run for different scenarios and the latest arrival times for each assembly area are determined. The optimum routes obtained are compared for these scenarios. It has aimed that, the proposed method will be used by organizations’ aims to improve their disaster strategies

Drinking Water Distribution Problem for Assembly Areas Post-Earthquake

Objective: The objective of the study is to minimize the latest arrival time to assembly areas in a determined region. The novel mathematical model is proposed for this problem handled. In the region, taking into account the four different scenarios that may occur as a result of the earthquake, the most suitable plan for drinking water distribution is created under each scenario.Methods: The problem addressed in the study is analyzed as a vehicle routing problem. Optimization techniques are generally used in solving the vehicle routing problem. Optimization can be expressed as “searching the best” regarding the purpose of the decision maker under certain conditions constraints . Thus, the phrase “finding the most suitable route” can be used for the vehicle routing problem. In this study, using the mathematical modeling approach, which is one of the optimization techniques, the best route that provides minimizing the latest arrival time to the assembly areas is proposed for decision makers.Results: Within the scope of the study, different damage levels that may occur after the earthquake are examined in the different scenarios for Sakarya, Turkey. The latest arrival times to assembly areas increase as the damage that may occur after the earthquake increases. The arrival times to the assembly areas are also different according to scenarios, because the optimum routes change for these scenarios.Conclusion: In this study, the drinking water distribution problem to assembly area is handled. The proposed mathematical model is run for different scenarios and the latest arrival times for each assembly area are determined. The optimum routes obtained are compared for these scenarios. It has aimed that, the proposed method will be used by organizations’ aims to improve their disaster strategies
