طراحی مدل استقرار مجدد آمبولانس‌های مکان‌یافته

Nowadays in all countries, public resources of health care may be inadequate to meet health care demands. Hence, the policy makers and providers of health care should provide citizens with most effective methods when available resources are limited. During the past decades, a large number of research efforts in the issue of health care and its applicable mathematical models have been considered by researchers and practitioners. In this regard, location and redeployment of ambulances is one of the main issues considered in which an attempt is made to maximally cover desired regions and service patients in emergency situations. This paper presents the issue of locating available ambulances with regards to demand pattern and redeploying the located ambulances. Toward this end, after locating the ambulances, a new mathematical model is developed with the aim of minimizing the expected value of total traveled distance by the ambulances. In addition, to shed light on the merit of proposed model, a set of numerical experiments is presented. By the end of the paper, the corresponding conclusions are presented.
