An Approximation Algorithm for the -level Uncapacitated Facility Location Problem with Penalties
The -level Uncapacitated Facility Location (UFL) problem is a generalization of the UFL and the -median problems. A significant shortcoming of the classical UFL problem is that often a few very distant customers, known as outliers, can leave an undesirable effect on the final solution. This deficiency is considered in a new variant called UFL with outliers, in which, in contrast to the other pr...
متن کاملApproximation algorithms for Capacitated Facility Location Problem with Penalties
In this paper, we address the problem of capacitated facility location problem with penalties (CapFLPP) paid per unit of unserved demand. In case of uncapacitated FLP with penalties demands of a client are either entirely met or are entirely rejected and penalty is paid. In the uncapacitated case, there is no reason to serve a client partially. Whereas, in case of CapFLPP, it may be beneficial ...

متن کاملAn approximation algorithm for a facility location problem with stochastic demands and inventories
In this article we propose, for any > 0, a 2(1 + )-approximation algorithm for a facility location problem with stochastic demands. This problem can be described as follows. There are a number of locations, where facilities may be opened and a number of demand points, where requests for items arise at random. The requests are sent to open facilities. At the open facilities, inventory is kept su...
متن کاملAn Approximation Algorithm for a Facility Location Problem with Inventories and Stochastic Demands
In this article we propose, for any > 0, a 2(1+ )-approximation algorithm for a facility location problem with stochastic demands. At open facilities, inventory is kept such that arriving requests find a zero inventory with (at most) some pre-specified probability. The incurred costs are the expected transportation costs from the demand points to the facilities, the operating costs of the facil...
