“…As an extended version of FLP, capacitated facility location problems (CFLP) reflect the restricted capacity of establishing facilities (Chauhan et al 2019). Since drones can distribute goods in vaster areas and cover more people in a shorter time (Vizvári et al 2019), many FLP studies have focused on determining the best locations of drones' launching and/or refueling facilities. Location problems are classified into the center, median and covering models (Golabi et al 2018).…”

Considering the recent lockdowns and travel bans due to COVID-19, novel tourism strategies are necessary to face the increasing need for innovative products and services and to ensure long-term sustainable growth. This study looks into the potential use of drones in providing online virtual tours of open-space tourist attractions. To do so, a novel mixed-integer linear mathematical model is developed to optimally determine the number and location of required facilities and the number of drones assigned to each center. The model is applied to a case study of Rome by selecting six historic sites as the tourist attractions and considering several candidate locations for establishing the facilities. The results of different potential scenarios imply that the project is profitable, even if the demand for virtual tours is low.

A világ számos nagyvárosa földrengésveszélyes övezetben fekszik. Ebben a dolgozatban ennek megfelelően egy nagyvárosban működő katasztrófaelhárítási rendszert tárgyalok. A városban valamilyen katasztrófát vagy katasztrófákat várunk, például földrengést és azt követő cunamit. A rendszer a katasztrófa után azonnal, autmatikusan működésbe lép. Természetesen egyes funkciókat emberek látnak el, de a cél az, hogy minél többet automata rendszerek. A segélycsomagok kiszállítása forgószárnyú drónokkal történik. Ugyancsak drónok végzik a felderítés, járőrözés és kisebb, egyéni segélycsomagok kiszállítását. A dolgozat tárgyalja a rendszer elveit, ideáltipikus működését, a nyújtott szolgáltatásokat, a felhasználható járműveket, egyéb műszaki kérdéseket és a pénzügyi vonatkozásokat.

“…Response refers to the use of emergency procedures and resources defined in emergency plans to save lives, the environment, properties, etc. The response, which needs an organization with many functions, must start immediately after the sudden event of the disaster with the available capacities (Vizvári et al , 2019). Recovery is the long-term action taken to restore normalcy and stabilize the community after the immediate impact of the disaster has passed (Whybark, 2015).…”

Purpose The total capacity of ambulances in metropolitan cities is often less than the post-disaster demand, especially in the case of disasters such as earthquakes. However, because earthquakes are a rare occurrence in these cities, it is unreasonable to maintain the ambulance capacity at a higher level than usual. Therefore, the effective use of ambulances is critical in saving human lives during such disasters. Thus, this paper aims to provide a method for determining how to transport the maximum number of disaster victims to hospitals on time. Design/methodology/approach The transportation-related disaster management problem is complex and dynamic. The practical solution needs decomposition and a fast algorithm for determining the next mission of a vehicle. The suggested method is a synthesis of mathematical modeling, scheduling theory, heuristic methods and the Voronoi diagram of geometry. This study presents new elements for the treatment, including new mathematical theorems and algorithms. In the proposed method, each hospital is responsible for a region determined by the Voronoi diagram. The region may change if a hospital becomes full. The ambulance vehicles work for hospitals. For every patient, there is an estimated deadline by which the person must reach the hospital to survive. The second part of the concept is the way of scheduling the vehicles. The objective is to transport the maximum number of patients on time. In terms of scheduling theory, this is a problem whose objective function is to minimize the sum of the unit penalties. Findings The Voronoi diagram can be effectively used for decomposing the complex problem. The mathematical model of transportation to one hospital is the P‖ΣUj problem of scheduling theory. This study provides a new mathematical theorem to describe the structure of an algorithm that provides the optimal solution. This study introduces the notion of the partial oracle. This algorithmic tool helps to elaborate heuristic methods, which provide approximations to the precise method. The realization of the partial oracle with constructive elements and elements proves the nonexistence of any solution. This paper contains case studies of three hospitals in Tehran. The results are close to the best possible results that can be achieved. However, obtaining the optimal solution requires a long CPU time, even in the nondynamic case, because the problem P‖ΣUj is NP-complete. Research limitations/implications This research suggests good approximation because of the complexity of the problem. Researchers are encouraged to test the proposed propositions further. In addition, the problem in the dynamic environment needs more attention. Practical implications If a large-scale earthquake can be expected in a city, the city authorities should have a central control system of ambulances. This study presents a simple and efficient method for the post-disaster transport problem and decision-making. The security of the city can be improved by purchasing ambulances and using the proposed method to boost the effectiveness of post-disaster relief. Social implications The population will be safer and more secure if the recommended measures are realized. The measures are important for any city situated in a region where the outbreak of a major earthquake is possible at any moment. Originality/value This paper fulfills an identified need to study the operations related to the transport of seriously injured people using emergency vehicles in the post-disaster period in an efficient way.
