Hierarchical Modeling Approach for Relief Logistics Nework Design

Indonesia has been stricken by so many disasters in the last decade. To name a few of the major disasters that happened in Indonesia are the Tsunami in Aceh in 2004, earthquake in Yogyakarta in 2006 and the recent earthquakes in southern Java and Western Sumatra provinces in 2009. One of the critical success factors in successful disaster management is effective logistics management. The objective of relief (humanitarian) logistics is to rapidly provide the appropriate emergency supplies to people affected by the disasters and to minimize human suffering and death. Logistics is also very important because it accounts for eighty percent of relief operations. This research is concerned with the development of hierarchical models to design relief logistics network for a country as geographically disperse as Indonesia archipelago. The modeling approach consists of two stages, namely pre-disaster and post-disaster stages, and developed according to Indonesia’s administration structure. This paper focuses on modeling for the response stage, which consists of a multi-period maximal covering location problem (MCLP) model to determine distribution points at the affected areas (village level facility), and a facility location-allocation model to decide the facility locations at the district level. The model is applied to analyze relief logistics network during the flood in Jakarta in the year of 2007
