Alternate second order conic programming reformulations for hub location with capacity selection under demand uncertainty
Dhyani, Sneha; Jayaswal, Sachin; Sinha, Ankur; Vidyarthi, Navneet (Indian Institute of Management Ahmedabad, 2018)In this paper, we study the single allocation hub location problem with capacity selection in the presence of congestion at hubs. Accounting for congestion at hubs leads to a non-linear mixed integer program, for which ... -
Capacitated multiple allocation hub location with service level constraints for multiple consignment classes
Jayaswal, Sachin; Vidyarthi, Navneet (IIM Ahmedabad, 2013-11)Hub-and-spoke systems have wide applications ranging in airline transportation, freight transportation, urban traffic, postal delivery, telecommunications and distribution in supply chains. These systems are usually ... -
An efficient solution approach for combinatorial bandwidth packing problem with queuing delays
Jayaswal, Sachin; Vidyarthi, Navneet; Das, Sagnik (Indian Institute of Management Ahmedabad, 2014)The Combinatorial bandwidth packing problem (CBPP), arising in a telecommunication network with limited bandwidth, is defined as: given a set of request, each with its potential revenue and consisting of calls with their ... -
Efficient solution of a class of location-allocation problems with stochastic demand and congestion

Hub interdiction & hub protection problems: Model formulations & exact solution methods
Ramamoorthy, Prasanna; Jayaswal, Sachin; Sinha, Ankur; Vidyarthi, Navneet (Indian Institute of Management Ahmedabad, 2016-10-25)In this paper, we present computationally effcient formulations for the hub interdiction and hub protection problems, which are bi-level and tri-level mixed integer linear programs, respec- tively. In the hub interdiction ...
