“…Mobasher, Ekici, and Özener (2015) coordinated appointment and pick-up times at blood donation sites to maximize platelet production. Elalouf, Hovav, Tsadikovich, and Yedidsion (2015) improved the structure of a three-echelon blood sample collection chain, which includes clinics, centrifuge centers, and a centralized testing laboratory. ¸S ahinyazan, Kara, and Taner (2015) developed a vehicle routing for a mobile blood donation system, with the primary objective of increasing blood collection levels.…”

“…In the healthcare domain, facility location studies typically focus on two types of health situations non-emergency and emergency. Non-emergency facility locations problems focus on locating optimal sites for primary care facilities, such as hospitals, clinics [ 23 , 24 , 25 ], blood banks [ 26 , 27 , 28 ], medical laboratories [ 29 ], mobile health units [ 30 ], and rehabilitation centers [ 31 ], as well as determining their capacities and allocation required resources. Locating emergency facilities is a more complex and challenging task that requires dealing with critical, urgent, and unpredictable situations.…”

The correct distribution of service facilities can help keep fixed and overhead costs low while increasing accessibility. When an appropriate location is chosen, public-sector facilities, such as COVID-19 centers, can save lives faster and provide high-quality service to the community at a low cost. The purpose of the research is to highlight the issues related to the location of COVID-19 vaccine centers in the city of Jeddah, Saudi Arabia. In particular, this paper aims to analyze the accessibility of COVID-19 vaccine centers in Jeddah city using maximal coverage location problems with and without constraint on the number and capacity of facilities. A maximal coverage model is first used to analyze the COVID-19 vaccination coverage of Jeddah districts with no restriction on the facility capacity. Then, a maximize capacitated coverage method is utilized to assess the centers’ distribution and demand coverage with capacity constraints. Finally, the minimize facilities model is used to identify the most optimal location required to satisfy all demand points with the least number of facilities. The optimization approaches consider the objective function of minimizing the overall transportation time and travel distance to reduce wastage on the service rate provided to the patients. The optimization model is applied to a real-world case study in the context of the COVID-19 vaccination center in Jeddah. The results of this study provide valuable information that can help decision-makers locate and relocate COVID-19 centers more effectively under different constraints conditions.

“…Also, Hovav and Tsadikovich [32] proposed a facility location inventory problem to reduce the cost of the influenza vaccination program. Elalouf et al [33] to reduce operating costs by repairing and maintaining blood sample collection chain have developed a model for facility location problem solving and proposed the dynamic programming (DP) algorithm and fully polynomial time approximation scheme (FPTAS) algorithm to solve it. Chaiwuttisak et al [34] proposed a binary integer programming model for locationallocation problem in two-level based on goals of improving blood supply while reducing transport costs.…”

Medicine unreliability problem is taken into consideration as one of the most important issues in health supply chain management. This research is associated with the development of a multiobjective optimization problem for the selection of suppliers and distributors. To achieve the purposes, the optimal quota allocation is determined with respect to disruption of suppliers in a five-echelon supply chain network and consideration of the distributor centers as a hub location-allocation mode. The objective of the optimization model is involved in simultaneous minimization of transactions costs dealing with suppliers, expected purchasing costs from suppliers, expected percentages of delayed and returned products in each distributor, as well as transportation cost in each echelon and fixed cost for distributor centers, and finally maximization of the expected scores for suppliers and high priority of product customers. The optimization problem is formulated as a mixed-integer nonlinear programming model. The proposed optimization model is utilized to investigate a numerical case study for asthma-specific medicines. The analyzing procedure is conducted based on the collected real data from Cobel Darou pharmaceutical company in 2019. Furthermore, a fuzzy multichoice goal programming model is considered to solve the proposed optimization model by R optimization solver. The numerical results confirmed the authenticity of the model.
