The location and locationrouting problem for the refugee camp network design
(Elsevier Ltd, 202101)The refugee crisis is one of the major challenges of modern society. The influxes of refugees are usually sudden and the refugees are in sheer need of services such as health care, education and safety. Planning public ... 
Humanitarian facility location under uncertainty: Critical review and future prospects
(Elsevier, 20210108)This paper provides a comprehensive review of the research done on facility location problems under uncertainty in a humanitarian context. The major goal is to summarize and help structuring this topic, which has increasingly ... 
Perspectives on modeling hub location problems
(Elsevier, 20201002)The aim of this paper is to provide insights for better modeling hub location problems to help create a road map for future hub location research. We first present a taxonomy to provide a framework for the broad array of ... 
Minimizing energy and cost in rangelimited drone deliveries with speed optimization
(Elsevier, 20210206)This paper introduces the Energy Minimizing and Range Constrained Drone Delivery Problem (ERDDP) in which drones are used to make deliveries to a number of customers and the drones themselves are transported by traditional ... 
The impact on heart rate and blood pressure following exposure to ultrafine particles from cooking using an electric stove
(Elsevier, 20200802)Cooking is a major source of indoor particulate matter (PM), especially ultrafine particles (UFPs). Longterm exposure to fine and ultrafine particles (UFPs) has been associated with adverse human health effects. Toxicological ... 
Exact and heuristic solution approaches for the airport gate assignment problem
(Elsevier, 20210130)In this study, we consider an airport gate assignment problem that assigns a set of aircraft to a set of gates. The aircraft that cannot be assigned to any gate are directed to an apron. We aim to make aircraftgate ... 
Ecodesign of ecolabels with coarse grades
(Elsevier, 20200203)We consider a thirdparty ecolabel certifier that aims to reduce the total environmental impact of production on nontarget resources and the total consumption rate of target resources. With these objectives the certifier ... 
On guarding real terrains: The terrain guarding and the blocking path problems
(Elsevier Ltd, 202107)Locating a minimum number of guards on a terrain such that every point on the terrain is guarded by at least one of the guards is known as the Terrain Guarding Problem (TGP). In this paper, a realistic example of the terrain ... 
Portfolio optimization with two quasiconvex risk measures
(Scientific and Technical Research Council of Turkey  TUBITAK,Turkiye Bilimsel ve Teknik Arastirma Kurumu, 20210326)We study a static portfolio optimization problem with two risk measures: a principle risk measure in the objective function and a secondary risk measure whose value is controlled in the constraints. This problem is of ... 
An exact algorithm for biobjective integer programming problems
(Elsevier Ltd, 202108)We propose an exact algorithm for solving biobjective integer programming problems, which arise in various applications of operations research. The algorithm is based on solving PascolettiSerafini scalarizations to search ... 
Hub location, routing, and route dimensioning: strategic and tactical intermodal transportation hub network design
(Institute for Operations Research and the Management Sciences (INFORMS), 202110)We propose a novel hub location model that jointly eliminates some of the traditional assumptions on the structure of the network and on the discount as a result of economies of scale in an effort to better reflect realworld ... 
The effect of economiesofscale on the performance of lotsizing heuristics in rolling horizon basis
(Taylor & Francis, 20200226)In this article, we consider the production planning problem in the presence of (dis)economiesofscale in production costs on a rolling horizon basis with a fixed forecast horizon. We propose variants of three wellknown ... 
Delegation of stocking decisions under asymmetric demand information
(Institute for Operations Research and the Management Sciences (INFORMS), 202101)Problem definition: We consider the incentive design problem of a retailer that delegates stocking decisions to its store managers who are privately informed about local demand. Academic/practical relevance: Shortages ... 
A branchandbound algorithm for team formation on social networks
(Institute for Operations Research and the Management Sciences (INFORMS), 2021)The team formation problem (TFP) aims to construct a capable team that can communicate and collaborate effectively. The cost of communication is quantified using the proximity of the potential members in a social network. ... 
An iterative vertex enumeration method for objective space based vector optimization algorithms
(EDP Sciences, 20210302)An application area of vertex enumeration problem (VEP) is the usage within objective space based linear/convex vector optimization algorithms whose aim is to generate (an approximation of) the Pareto frontier. In such ... 
Certainty equivalent and utility indifference pricing for incomplete preferences via convex vector optimization
(Springer, 202103)For incomplete preference relations that are represented by multiple priors and/or multiple—possibly multivariate—utility functions, we define a certainty equivalent as well as the utility indifference price bounds as ... 
Trading off health and financial protection benefits with multiobjective optimization
(John Wiley & Sons Ltd., 20201018)Countries which are introducing a system of Universal health coverage have to make a number of key tradeoffs, of which one is the tradeoff between the level of coverage and the degree to which patients are exposed to ... 
Detection and identification of changes of hidden Markov chains : asymptotic theory
(Springer Netherlands, 20211006)This paper revisits a unified framework of sequential changepoint detection and hypothesis testing modeled using hidden Markov chains and develops its asymptotic theory. Given a sequence of observations whose distributions ... 
Performance comparison of feature selection and extraction methods with random instance selection
(Elsevier Ltd, 20211001)In pattern recognition, irrelevant and redundant features together with a large number of noisy instances in the underlying dataset decrease performance of trained models and make the training process considerably slower, ... 
Covering vehicle routing problem: application for mobile child friendly spaces for refugees
(Springer, 202102)The world is facing a largescale refugee crisis because of the ongoing war in Syria, and it is important to improve refugees’ life conditions from a humanitarian point of view. In order to analyse the living conditions ...
