Supply chain network design (SCND) is a key strategic decision in supply chain
management (SCM). One particular area of SCND is concerned with disruption risk …

The main issue in p-hub median problem is locating hub facilities and allocating spokes to
those hubs in order to minimize the total transportation cost. However hub facilities may fail …

This paper investigates the design of reliable supply networks to make them resilient to
unpredictable disruptions. We develop an optimization model that incorporates several …

Hub location problem (HLP) is one of the strategic problems encountered in designing
transportation and telecommunication networks. Regardless of the considered objective in …

The hub location problem has been widely used in analyzing hub-and-spoke systems. The
basic assumption is that a large number of demands exist to travel from origins to …

Facility systems may be vulnerable to a disaster, whether caused by intention, an accident,
or by an act of nature. When disrupting events do occur, services may be degraded or even …

Supply chains, as vital systems to the well-being of countries and economies, require
systematic approaches to reduce their vulnerability. In this paper, we propose a non linear …

This research proposes a spatial optimization problem over a multi-modal transportation
network, termed the q-Ad-hoc hub location problem (AHLP), to utilize alternative hubs in an …

Abstract The Multiple Knapsack Assignment Problem (MKAP) has been solved successfully
using heuristics, but important special cases have not yet been dealt with. Motivated by an …

With respect to a traditional point-to-point (PP) network, a hub-and-spoke (HS) network not
only uses a smaller number of links/paths but also utilizes the scale economy advantage on …
