3.1 Casualty Transportation and evacuation
Casualty transportation is one of the most critical actions in emergency logistics. Casualty transportation includes
evacuation and people flow from affected areas to medical centers.Most of the researchers focus on minimizing the
travel cost and travel time, as outlined in the Table I, II, and III.Minimization of travel time leads to improvement in
overall response and is sought for identifying the right path with minimum risk for transportation.
The objective functions that are used to optimize casualty transportation operations with the corresponding
constraints are depicted in Table 1, 2 and 3. Important and recurrent objective functions discussed in literature and
outlined in the table 1, 2 and 3.are:
Travel cost - Maintenance Cost, Idle time cost of vehicle and Travel distance cost.
Loading and Unloading Time – Loading and unloading time of resources to and from the vehicle.
Distance – Short path selection.
Travel time – Minimum travel time.
Evacuation time–Minimum evacuation time.
Distance – Selection of path based on shortest path.
Quantity– Unmet Demand and demand satisfaction, Total life saving, Number of emergency units needed
