Rapid Distribution of Medical Supplies

Incorporating Socio-Economic Factors in Maximizing Two-Dimensional Demand Coverage and Minimizing Distance to Uncovered Demand: A Dual-Objective MCLP Approach for Fire Station Location Selection

“…Despite these advancements, the model's provision for secondary service options in the event of unforeseen circumstances was non-existent. This prompted Dessouky et al [13] to introduce a layered approach to coverage. They put forth a multi-tiered objective function (Equation ( 4)), which seeks to minimize the cumulative distances between demand points and their respective facilities, adjusting for the priority level of each layer and the population density at each point.…”

Multi-period vaccine allocation model in a pandemic: A case study of COVID-19 in Australia

“…In allocating vaccine, factors such as stage of pandemic in geographical regions should be taken into account. Dessouky et al (2013) To optimize the facility location and vehicle routing decisions in large-scale disaster relief Mathematical modeling Population size, distance, number of facilities and vehicle, vehicle capacity Stationary It is shown how the proposed model is considered in an anthrax emergency. Matrajt et al (2013) To optimize vaccine distribution in a group of cities Mathematical model Illness attack rate, recovery rate, fraction of symptomatic, contact rates, vaccine efficacies, probability of transmission unknown The results indicate that the optimal allocation strategy changes depend on the status of the pandemic.…”

A decision support system for prioritised COVID-19 two-dosage vaccination allocation and distribution

“…Owing to short supply and huge demand commonly for vaccines as well as time-space constraints, most studies on pandemic vaccine supply chains focus on prioritising allocation of vaccines to the neediest in the populace as discussed previously. Nevertheless, rapid distribution of medical supplies plays a crucial role in the effectiveness and efficiency of disaster response, hence the overall performance of the healthcare system ( Al Theeb and Murray, 2017 , Dessouky et al, 2013 ). Therefore, upon determination of the priority groups for vaccination, delivery of vaccine to the targeted groups becomes primarily an assignment problem ( Gamchi et al, 2020 ).…”

“… Özdamar and Demir (2012) To develop transportation plans of the last mile delivery and pick-up problem in large-scale disaster relief A hierarchical cluster and route procedure (HOGCR) for coordinating vehicle routing in large-scale post-disaster distribution and evacuation activities Operational logistics plans are devised based on estimates of deliveries and evacuations necessary information such as population is known with certainty The proposed optimisation approach can obtain in 15 min CPU time solutions within a percentage deviation of less than 12% from a strong lower bound for large-scale relief networks. Dessouky et al (2013) To help design an efficient pharmaceutical supply chain with strategic locations to place warehouses and inventories and optimal routes for distribution vehicles Mathematical models to solve facility location and vehicle routing problems in the context of a response to a large-scale emergency The plans need to be flexible enough to accommodate contingencies of daily operations. They must consider the stochastic nature of the problem, such as uncertain demand, traffic conditions, etc.…”
