The location problem of emergency materials in uncertain environment
AbstractThe hazards and unpredictability of emergencies have made people pay
more and more attention to emergency response. A reasonable reserve of
emergency materials can play an important role in post-disaster rescue.
This paper uses the uncertain comprehensive evaluation method to grade
the emergency materials, and establishes a location model for the
uncertain emergency materials.The location of the reserve point is
determined by maximizing the rescue satisfaction, the maximum number of
service demand points under the maximum coverage, and pursuing the
minimum sum of the distance from the demand point to the reserve point.
Based on the uncertainty theory, the uncertain emergency materials
location model is converted into an equivalent deterministic emergency
materials location model, and the model is solved by a tabu search
algorithm. Finally, a numerical experiment is given to illustrate the
idea of the uncertain model.
