Determining medical aid distribution route using multi-objective optimization

The distribution of medical aid during disasters should be executed optimally and equally to the victims. The focus of the medical aid distribution cannot be only one objective but should be several objectives that might be conflicting. This research creates a distribution route for Merapi eruption case using multiple-objectives; to minimize travel distance, travel time, and considering priorities for the shelters with higher demand. The results are compared with the single objective model which minimizes travel distance as the objective. The travel distance generated for Cluster 1 is 55.9 km, Cluster 2 is 47.1 km, Cluster 3 is 35.9 km, Cluster 4 is 52.8 km, and Cluster 5 is 79.8 km. In comparison to the single objective model, the 12,03% distance increment is statistically not significant whereas the 21,16% demand fulfillment level increment is statistically significant. Hence, multi-objectives model works better than the single-objective model.
