Abstract:
Because of the lack of human ability to predict the occurrence of earthquake, the volume of demand caused by this natural and unexpected disaster is very high for relief and rescue operations and relief centers that provide urban needs in normal circumstances, often are unable in response to the created demand at the right time. Hence preparedness for occurrence of this natural disaster is essential.
In crtical situation after the occurrence of earthquake, all government and aid organizations such as Red Crescent and the army distribute and send relief commodities to respond to the demand that is created in the crisis-hit region. In this situation, the government seeks to reduce the amount of unsatisfied demand and also aid organizations want to minimize the travel time. To deal with the considering problem, the bi-level model with government in upper level and aid organizations in lower level is used. Also to reduce response time and lack of maintenance of inventory in this situation, the cross-docking technique has been used for aid organization.
The proposed model is multi-period and has been modeled in two phases. In the first phase, the survived population is allocated to the temporary sites to determine the demand of each commodity and in the second phase bi-level modeling is done to distribute the relief commodities. The following is an uncertain scenario-based model has been developed based on the basic model. In this study, Fuzzy Goal Programing approach is used to solve the two-level models.
Finally, the two-phase two-level model in deterministic and undeterministic circumstances is used to investigate the propable earthquake of Msshhad in region 9 and also investigating the cross-docking system for Red Crescent in this situation and the result are presented.
