A MODEL FOR DESIGNING A BLOOD SUPPLY CHAIN NETWORK TO EARTHQUAKE DISASTERS (CASE STUDY: TEHRAN CITY)

Abstract

One of the most devastating events is earthquake. Along with planning for supply and the proper distribution of relief goods including food and cloths, one of the most vital issues is to relieve to injured people who are in need of blood. In this research, we design a blood supply chain when the earthquake takes place, should the need arises by people requesting the blood units. Based on this need, a multi-level multi-objective mathematical model is designed during several periods based on minimizing the cost of the blood supply chain network and maximizing the reliability of the selectable paths for blood transportation. This model determines the optimal number and locations for establishing the facilities as well as determining the allocation of blood to various facilities, and, on the other hand, optimal routes for blood transportation among facilities. The mathematical model presented is validated by data acquired from implemented model of Tehran city.
