Hubs facilitate aggregation of connection, and switching points of material and people flow
to reduce costs as well as environmental pollution. Hub Location Problem (HLP) is a …

Hubs are critical components of transportation and distribution systems, and hub networks
play a special role in freight and passenger transportation services worldwide. This paper …

Nowadays, designing a reliable hub network has become a critical issue in the process of
transporting goods from an origin to a destination. Due to intentional disasters, both location …

This paper proposes a multi-objective mixed-integer linear programming to model a cold
chain with complementary operations on a hierarchical hub network. Central hubs are linked …

Flexible job shop scheduling problem is one of the most important topics in production
management and is one of the most complex topics in combinatorial optimization. This …

Water shortage has become a significant challenge in many regions, affecting sectors such
as agriculture, energy, industry, and the economy. Based on this subject matter and …

Hub networks are the foundation of many transportation and distribution systems, and real-
world hub networks often transport freight or passengers of different service classes. This …

In this paper, we study the bi-criteria p-hub median and dispersion problem, that arises in
the design of hub networks where the dispersion of hubs is desired to mitigate the risk of …

ABSTRACT p-Hub location-allocation problem is one of the most interesting subjects in the
location theory. Hubs act as switching points to reduce the transportation cost. In this study …

Hub facilities are centralized locations that consolidate and distribute the commodities in
transportation networks. In many real world applications, transport service providers may …
