Balancing the level of relief inventory is challenging since the balancing operation may lead to further imbalanced condition. We propose a spatial strategy to even out the inventory level through transshipment, and control the transshipment operations in the environment of low credible relief’s information. This information includes: number of evacuees, demand rate, logistic leadtime, etc. Here, we compared three strategy schemes: without lateral transshipment, with fully lateral transshipment, and partial transshipment. The first two strategies are representing selfish and altruistic behaviors, respectively. The later represents a moderate behavior between selfish and altruistic. In our model, each unit of inventory interacts and controls its action based on those strategies. To demonstrate applicability of our model, we used data of one volcanic eruption occurring in North Sumatra Indonesia on November 2013. The result revealed that the best performance, measured by total inventory cost and inventory’s health, was achieved by the partial transshipment with an updating method called dynamic support. With this strategy, the average inventory level increased about 50% and the frequency of transshipment operations reduced to 20%. These results, however, can be achieved only on low onset type of disaster events and sufficient number of logistic transporters is available. Based on the case study, we recommend a new way of relief inventory operations, thus the government and disaster relief organizations can get benefit from it.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Disaster response,Lateral trans shipments,Relief inventory,Spatial games,Volcanic eruptions[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Disaster response,Lateral transshipment,Relief inventory,Spatial game theory,Volcanic eruption[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
