This paper deals with a fixed order review inventory model with an unknown distribution pattern of transportation lead time, in which lateral transshipment between two shelter points are allowed. This assumption is appropriate after occurrences of any disaster events. Each shelter point will classify their stock level into three categories, which is high, medium, and low. In case of a shortage at some location, another location will supply some amount of their stock with certain probability. This action raises a risk of causing a shortage for themselves if not carefully managed. We model balancing problem under such a condition where the distribution pattern of delivery time is unknown and number of transportation vehicle is limited. The simulation results show that mutual support system resulted in better performance measured by the number of shortage shelter points. Our approach is relatively simple and applicable in a situation with high uncertainties.
