Timely supply of vital materials to disaster hit areas plays a critical role in emergency relief. The problem involves warehouse selection, fleet routing, and scheduling so as to meet demand in the strict time window. The problem is NP-hard, in general, and extremely difficult to solve. The congestion caused by heavy traffic further aggravates the problem.(More)
Supplying emergent materials for a disaster area in time plays a vital role in emergency response. Supply location selection and routing problem including warehouse selection and fleets scheduling and routing to guarantee to meet the demand in the required time window considered in this paper is a new and difficult problem and is proved to be NP-hard.

The supply location selection and routing (SLSR) problem integrates warehouse selection, and fleet routing and scheduling to optimize the supply chain and guarantee timely material delivery for disaster areas. Demand uncertainties are the inherent nature of the emergency material supply. In this paper, the SLSR problem is studied in considering uncertain(More)
