چکیده مقاله
Quick response to the urgent relief needs in metropolis is vital to alleviate the disaster impacts in the affected areas In disaster situations, many people call emergency services simultaneously, but the number of emergency vehicles are not sufficient to visit all the victims immediately This paper studies ambulance fleet management to minimize the total service completion time among all patients in disaster response phase Since, the victim’s condition get worse and become life threatening over the time, semi soft time window constraint is incorporated to reflect penalties on late arrivals In order to utilize the ambulances efficiently, we subdivide the patients to three groups based on their severity of injuries and allocate the ambulances to the patients according to vehicle capabilities In the following, the problem is implemented by the GAMS software and various numerical instances are generated to evaluate the proposed model Finally, a sensitivity analysis is presented to assess the relationship between the problem structures and optimal solutions
