A biobjective method for sample allocation in stratified sampling
(Elsevier, 2007-03-01)
The two main and contradicting criteria guiding sampling design are accuracy of estimators and sampling costs. In stratified random sampling, the sample size must be allocated to strata in order to optimize both objectives. ...

Exact procedures for solving the discrete ordered median problem
(Elsevier, 2006-11)
The Discrete Ordered Median Problem (DOMP) generalizes classical discrete location problems, such as the N-median, N-center and Uncapacitated Facility Location problems. It was introduced by Nickel [S. Nickel. Discrete ...

Dynamically second-preferred p-center problem
(Elsevier, 2023)
This paper deals with the Dynamically Second-preferred p-center Problem (DSpP). In this problem, cus- tomers’ preferences and subsets of sites that each customer is willing to accept as service centers are taken into ...

When centers can fail : A close second opportunity
(Elsevier, 2015)
This paper presents the p-next center problem, which aims to locate p out of n centers so as to minimize the maximum cost of allocating customers to backup centers. In this problem it is assumed that centers can fail and ...
