A model for planning locations of temporary distribution facilities for emergency response

• We propose a location-allocation model for emergency response planning.
• We consider dynamic selection of temporary relief facilities.
• Allowing transfer of excess resources to next period makes relief supply more effective.
• Increasing distribution periods in a response planning horizon can meet demand better.
• Locations of relief facilities in the distribution periods affect the total cost.

We propose a network flow model for dynamic selection of temporary distribution facilities and allocation of resources for emergency response planning. The model analyzes the transfer of excess resources between temporary facilities operating in different time periods in order to reduce deprivation. Numerical analysis shows that the location of temporary facilities is determined by the demand and supply points. This work contributes to the emergency response planning that requires a quick response for the supply of relief materials immediately after a disaster hits a particular area.
