The main problem in disaster relief logistics, among others unpredictability of demand in terms of timing and location, suddenly-occurring demand in very large amounts and short lead times for a wide variety of supplies, high stakes associated with adequate and timely delivery, lack of resources such as supply, people, technology, transportation capacity, and budget. The role of decision support systems are needed to help decision maker’s better plan in humanitarian logistics operations. The aim of research is develop an inventory model in humanitarian logistics namely create a computer model as decision support system. The model proposed here aims to coordinate the transportation of commodities from major supply centres to distribution centres in affected areas. The goal is to minimize delay in providing prioritized commodity. System dynamics methodology was developed to assist with complex decision making in humanitarian logistics. Specifically, it was developed to study systems characterized by multiple feedback loops, uncertainty, and time lags. This paper has been introduced the usage of system dynamic methodology that has expanded to include social and environmental issues. As such, it is therefore an appropriate methodology to capture the complexity of these systems.
