Exact Method and Iterative Approach to Solve a Case Study of the National Social Security Fund

Without a doubt, healthcare is currently one of the main social and economic problem in the world and one of the most important problems treated we have healthcare facility location which is our interest in this study. Given the growth of the population in Tunisia, we need to increase the number of the health-care facilities over the next years. Actually, we are interested to the case of the specific pharmacy of the National Social Security Fund policlinic of Tunisia (NSSF). The specific pharmacy is charged of providing specific treatments for serious diseases requiring long-term care such as: Chemotherapy, Osteoporosis and the Parkinson. This pharmacy is a separate pharmacy in the NSSF’ policlinics which is available only in 3 policlinics. From this, we can notice that they are not well located and we can imagine congestion and the waste of time, so we can conclude that they are not able to cover all regions. In this paper, we hope to solve this situation by engaging a set of other pharmacies of the 24 Tunisian cities to deliver these drugs. More precisely, if the city is scheduled in the tour, so it's request will be served directly. If it isn't the case and the city isn't along the tour, it will be covered by another visited city.
