A robust optimization approach for the winner determination problem with uncertainty on shipment volumes and carriers’ capacity

A Robust Winner Determination Problem for Combinatorial Transportation Auctions under Uncertain Shipment Volumes

Combinatorial auctions are widely used for the procurement of transportation services. In these auctions, shippers act as auctioneers who need to outsource a number of transportation services to external carriers. Carriers compete by submitting bids on packages of shippers' requests. After receiving all carriers' bids, the shipper solves the well-known winner determination problem (WDP) in orde...

A Robust Optimization Methodology for Multi-objective Location-transportation Problem in Disaster Response Phase under Uncertainty

This paper presents a multi-objective model for location-transportation problem under uncertainty that has been developed to respond to crisis. In the proposed model, humanitarian aid distribution centers (HADC), the number and location of them, the amount of relief goods stored in distribution centers, the amount of relief goods sent to the disaster zone, the number of injured people transferr...

A Robust Optimization Approach for a p-Hub Covering Problem with Production Facilities, Time Horizons and Transporter

Hub location-allocation problems are currently a subject of keen interest in the research community. However, when this issue is considered in practice, significant difficulties such as traffic, commodity transportation and telecommunication tend to be overlooked. In this paper, a novel robust mathematical model for a p-hub covering problem, which tackles the intrinsic uncertainty of some param...

Robust Winners and Winner Determination Policies under Candidate Uncertainty

We consider voting situations in which some candidates may turn out to be unavailable. When determining availability is costly (e.g., in terms of money, time, or computation), voting prior to determining candidate availability and testing the winner’s availability after the vote may be beneficial. However, since few voting rules are robust to candidate deletion, winner determination requires a ...
