An Efficient Imperialism Competitive Algorithm for a Reliable Hub Covering Location Problem

Abstract

Abstract-Hubs are critical elements that benefit networks by switching, distributing and concentrating flows. A hub location problem is common in a lot of industries, such as transportation networks, telecommunication networks, postal delivery networks and express shipment. Furthermore, a transportation network plays a vital role in each country. Nonetheless, during a day many factors such as traffic incidence, natural disasters cause some degradation in the transportation network. As a result, in this paper, we study a reliable hub covering location problem in a degradable transportation network to minimize the total transportation cost. For achieving near-optimal solutions for a real-sized problem an imperialism competitive algorithm (ICA) is proposed. Also the effectiveness of the proposed ICA is shown by some computational experiments. At last, conclusion is provided.

A multi-objective three-level hierarchical hub location-queue problem with congestion and reliability under uncertainty: A case study

“…This Constraint considers a high limit for this route from the network. The time it takes for the flow to go from the source to the destination node is the subject of constraints (30) to (32). Constraint (33) guarantees that there is no loop between ground hub and airport hub.…”

“…In hierarchical problems and systems, decisions are made about the location of interacting facilities in a multi-layered configuration with different service levels and the The research on hierarchical hub location that researchers have conducted is listed in Table 1, along with the differences between the current study and earlier research. Some research projects have been completed, though, regarding uncertainty [16][17][18][19][20][21][22][23][24][25][26][27][28]. Numerous research studies have been conducted on solution techniques to date [29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46].…”
