Abstract
Generally, relief inventory models assume uniform or normally distributed demand pattern and planning horizon for those models is unbounded. However, relief demand becomes zero after certain period. This study formulates a relief inventory model for a limited relief operation period. Secondary hub collects relief from primary hub and then distributes those relief items to local distribution center. A large stock of relief items in a secondary hub is not rational and may causes shortage in other affected areas. Therefore, inventory replenishment strategy is proposed for different types of demand distributions by changing parameter values. It is found that the system cost for all parameter values is stable. The order quantity in each replenishment cycle varies and has a certain pattern. A sensitivity analysis for several parameters are also presented.
