چکیده

In this paper we formalize and initiate the study of heterogeneous k-facility location without money, a problem akin to the classical k-facility location problem but encompassing a richer model and featuring multi-parameter agents. In particular, we consider truthful mechanisms without money for the problem in which heterogeneous (i.e. serving different purposes) facilities have to be located and agents are only interested in some of them. We study the approximation factor that can be achieved by truthful mechanisms in this setting and present some bounds which make a surprising parallel with our knowledge of truthfulness for the classical single-dimensional facility location problem.

Heterogeneous Facility Location without Money: (Doctoral Consortium)

The facility location problem is arguably the prototypical problem in the mechanism design without money’s research agenda. Motivated by the intrinsic limitations of the classical model on both (i) adequately modelling several real life scenarios and (ii) admitting truthful mechanisms having good approximation ratio, we introduce and study a novel, more realistic model of facility location, whe...

Truthful Mechanisms without Money for Non-Utilitarian Heterogeneous Facility Location

In this paper, we consider the facility location problem under a novel model recently proposed in the literature, which combines the no-money constraint (i.e. the impossibility to employ monetary transfers between the mechanism and the agents) with the presence of heterogeneous facilities, i.e. facilities serving different purposes. Agents thus have a significantly different cost model w.r.t. t...

Heterogeneous facility location without money

The study of the facility location problem in the presence of self-interested agents has recently emerged as the benchmark problem in the research on mechanism design without money. In the setting studied in the literature so far, agents are single-parameter in that their type is a single number encoding their position on a real line. We here initiate a more realistic model for several real-lif...

A Multi-objective Hierarchical Location-allocation Model for the Healthcare Network Design Considering a Referral System

This paper presents a multi-objective and multi-service location-allocation model with capacity planning to design a healthcare facilities network through considering a referral system. Therefore, a mixed integer nonlinear programming (MINLP) model containing two objective functions is proposed. The first objective function is  relates to minimization of total opening cost, minimization of tota...

Heuristic Methods Based on MINLP Formulation for Reliable Capacitated Facility Location Problems

This paper addresses a reliable facility location problem with considering facility capacity constraints. In reliable facility location problem some facilities may become unavailable from time to time. If a facility fails, its clients should refer to other facilities by paying the cost of retransfer to these facilities. Hence, the fail of facilities leads to disruptions in facility location dec...
