Multi-Period Vehicle Routing & Replenishment Problem of Neighbourhood Disaster Stations for Pre-Disaster Humanitarian Relief Logistics

Routing disaster relief vehicles in a humanitarian supply chain

Background and objectives: The decision to allocate the optimal route for ambulances affects the success of disaster response and the safety of victims. In this paper, a multi-objective optimization model is proposed to determine the route of vehicles in response to humanitarian relief supplies.  Method: Two objective functions are formulated to improve efficiency and effectiveness. The first g...

A time-dependent vehicle routing problem for disaster response phase in multi-graph-based network

Logistics planning in disaster response phase involves dispatching commodities such as medical materials, personnel, food, etc. to affected areas as soon as possible to accelerate the relief operations. Since transportation vehicles in disaster situations can be considered as scarce resources, thus, the efficient usage of them is substantially important. In this study, we provide a dynamic vehi...

Multi-objective routing and scheduling for relief distribution with split delivery in post-disaster response

Following the occurrence of unexpected events and natural disasters, a highly important relief operation is the transferring of relief commodities from the distribution centers (CDs) to shelters. In this paper, a three-level network consisting of depot of vehicles, distribution centers and shelters has been considered for routing and scheduling of relief vehicles through introducing a multi-obj...

Multicriteria Cost Assessment and Logistics Modeling for Military Humanitarian Assistance and Disaster Relief Aerial Delivery Operations

Balancing pre-disaster preparedness and post-disaster relief

Challenges associated with resource allocation to mitigate and recover from natural and man-made disasters inspire new theoretical questions for decision making in the intertwined natural and human world. Disaster loss is determined not only by post-disaster relief but also the pre-disaster mitigation and preparedness. To examine the decision making process at ex ante and ex post disaster stage...
