This paper investigates the optimal locations of health service facilities during the Hajj, a major temporary city event in Mina, Saudi Arabia, attended by millions of pilgrims. Given the logistical challenges and historical accident risks during this dense gathering, effective placement of...

Background: This paper introduces an enhanced multi-period p-mobile hub location model that accounts for critical factors such as service time, flow processing delays, and congestion impacts at capacity-constrained hubs. As (urban) transportation networks evolve, mobile hubs play an increasingly...

Background: Brazil is one of the largest consumers of fertilizers and is highly dependent on the international market to meet its demand for agricultural production inputs. The complexity of the fertilizer supply chain motivated us to carry out this study on redesigning the fertilizer logistics...

Startups, understood as new forms of innovative and fast-growth ventures, are emerging in traditional industries, creating intense competition and displacing former leaders. Our study focuses on location theory embedded in institutional and resource context and its application to startups in the...

We investigate a facility location problem with modular capacity under demand uncertainty arising at Hydro-Québec, the largest public utility in Canada. We propose a mathematical model to locate the facilities, determine the capacity levels, and compute the number of service teams needed in...

We study the reliable (uncapacitated) facility location (RFL) problem in a data-driven environment where historical observations of random demands and disruptions are available. Owing to the combinatorial optimization nature of the RFL problem and the mixed-binary randomness of parameters...

HighlightsWe consider the problems of optimal location of rescue service facilities (humanitarian or medical aid) and zoning the territory simultaneously with placing centers in case of emergencies or natural disasters.The proposed mathematical models are discrete-continuous problems of multiple...

Background: Possible solutions to overcome the many challenges of home delivery are collection and delivery points (CDPs). In addition to commercial facilities, the role of CDPs can also be played by users' households, providing a crowd storage service. Key decisions regarding CDPs relate to...

Hotelling's model, commonly referred to as the "linear city" model, is perhaps the most widely-used model of competition in differentiated products. However, pure-strategy Nash equilibria in prices do not exist unless the firms are located either sufficiently far apart from each other or at the...
