A Three-Stage Mixed Integer Model Proposal in Disaster Logistics

Öz

The number of people who died because of disasters in the world and Turkey is increasing day by day. Some of the people who died die during the disaster, and some of them die due to inadequacies after the disaster. For this reason, it has become an important issue to plan the actions before and after the disaster Regarding this issue, researchers have focused on disaster logistics in recent years. The stages of disaster logistics are pre-disaster preparedness, disaster response process and post-response logistics activities. In this study, a 3-stage mixed integer mathematical model is proposed to transport people in crisis areas to shelters and health centers after disasters, as well as to provide the necessary needs and health supplies to people through warehouses from suppliers. This mathematical model was tested with a small data set and the results were shared.

Afet Lojistiğinde Üç Aşamalı Karma Tamsayılı Bir Model Önerisi

Öz

Dünyada ve Türkiye’de afet nedeniyle hayatını kaybeden insanların sayısı günden güne artmaktadır. Ölen insanların bir kısmı afet esnasında bir kısmı ise afet sonrasındaki yetersizlikler sebebiyle hayatını kaybetmektedir. Bu sebeple afet öncesinde yapılan ve sonrasında yapılacak işlemlerin önceden planlanması önemli bir konu haline gelmiştir. Bu konu ile ilgili olarak araştırmacılar son yıllarda afet lojistiği üzerinde durmaktadırlar. Afet lojistiğinin aşamaları afet öncesi hazırlık, afet müdahale süreci ve müdahale sonrası lojistik faaliyetler şeklindedir. Bu çalışmada afet sonrasında kriz alanındaki insanların barınaklara ve sağlık merkezlerine taşınması, aynı zamanda tedarikçilerden depolar vasıtasıyla barınaklarda bulunan insanlara zaruri ihtiyaçlarını sağlık merkezinde bulunan insanlara ise zaruri ihtiyaçlarını ve sağlık malzemelerini taşınmasını sağlamak üzere üç aşamalı karma tamsayılı bir matematiksel model önerilmiştir. Bu matematiksel model küçük bir veri seti ile test edilerek sonuçları paylaşılmıştır.
