Mechanism design studies how to design mechanisms that result in good outcomes even when agents strategically report their preferences. In traditional settings, it is assumed that a mechanism can enforce payments to give an incentive for agents to act honestly. In many Internet application domains, however, introducing monetary transfers is impossible or undesirable. Also, in such highly anonym...

Most companies operate to maximize profits and increase their market shares in competitive environments. Since the proper location of facilities conditions profits, facility problem (CFLP) has been extensively applied literature. This generally falls within class NP-hard problems, which are difficult solve. Therefore, choosing a solution method optimize is key factor. Even though CFLPs have con...

Choosing locations to provide service under various constraints and objectives is an essential logistic activity in several contexts. Manufacturers choose locations for facilities and sales depots, government agencies choose locations for fire stations and other service installations, politicians choose ideological positions in the space of political agendas, etc. The field of location theory i...

This paper studies a reliable facility location problem with facility protection that aims to hedge against random facility disruptions by both strategically protecting some facilities and using backup facilities for the demands. An Integer Programming model is proposed for this problem, in which the failure probabilities of facilities are site-specific. A solution approach combining Lagrangian...

— We treat a discrete uncapacitated facility location problem where the installation cost per facility is a gênerai nonlinear function of the number of established facilities. Assuming a convexity proper ty, Mirchandani and Jagannathan developed a heur is tic solution procedure for this problem. Hère, we show how to modify their algorithm in order to get and prove exact solutions and, at the sa...

Background and objective: The location of facilities is of great importance in healthcare and is of interest to researchers due to its importance. In this regard, a large proportion of classic location-allocation models concentrate on solving problems in an exclusive environment (non-competitive), but this assumption is rarely true in reality. Methods: At...

Under study is the problem of locating facilities when two competing companies successively open their facilities. Each client chooses an open facility according to his own preferences and return interests to the leader firm or to the follower firm. The problem is to locate the leader firm so as to realize the maximum profit (gain) subject to the responses of the follower company and the availa...
