Contracting under uncertain capacity
(Inderscience publishers, 2010)In this paper, we develop a two-stage supply-chain in which a supplier with uncertain capacity sells to a retailer facing a Newsvendor problem. We analyze the centralized system where both partners take their decisions ... -
The periodic vehicle routing problem with driver consistency
(Elsevier, 2018)The Periodic Vehicle Routing Problem is a generalization of the classical capacitated vehicle routing problem in which routes are determined for a planning horizon of several days. Each customer has an associated set of ... -
On explicit solutions of a two-echelon supply chain coordination game
(Springer Verlag, 2018)A contracting game under asymmetric information specific to two-echelon supply chain coordination between a retailer of unknown type and a supplier is studied. When the parameter which is private information to the retailer ... -
Benders decomposition algorithms for two variants of the single allocation hub location problem
(Springer New York LLC, 2018)The hub location problem (HLP) is a special type of the facility location problem with numerous applications in the airline industry, postal services, and computer and telecommunications networks. This paper addresses two ... -
The venue management problem: setting staffing levels, shifts and shift schedules at concession stands
(Springer New York LLC, 2018)The aim of this research is to determine staffing requirements as well as shift scheduling, with the objective of maximizing the expected contribution from the venue. We specifically consider theaters where demand at ... -
Tractability of convex vector optimization problems in the sense of polyhedral approximations
(Springer New York LLC, 2018)There are different solution concepts for convex vector optimization problems (CVOPs) and a recent one, which is motivated from a set optimization point of view, consists of finitely many efficient solutions that generate ... -
Robust trading mechanisms over 0/1 polytopes
(Springer New York LLC, 2018)The problem of designing a trade mechanism (for an indivisible good) between a seller and a buyer is studied in the setting of discrete valuations of both parties using tools of finite-dimensional optimization. A robust ... -
Bilateral trade in discrete type spaces by linear and convex optimization with application to supply chain coordination
(INSA Lyon, 2018)We consider the bilateral trade of an object between a seller and a buyer through an intermediary who aims to maximize his expected gains as in Myerson and Satterthwaite [1], in a Bayes-Nash equilibrium framework where the ... -
On robust portfolio and naïve diversification: mixing ambiguous and unambiguous assets
(Springer New York LLC, 2018)Effect of the availability of a riskless asset on the performance of naïve diversification strategies has been a controversial issue. Defining an investment environment containing both ambiguous and unambiguous assets, we ... -
Mechanistic modeling of micro milling including tool run-out
(Gazi Üniversitesi Mühendislik-Mimarlik, 2018)Micro milling is widely used in precision manufacturing industry to produce micro components made from difficult-to-cut materials. High material removal rate and ability to create good surface quality are the major advantages. ... -
Robust auction design under multiple priors by linear and integer programming
(Springer New York LLC, 2018)It is commonly assumed in the optimal auction design literature that valuations of buyers are independently drawn from a unique distribution. In this paper we study auctions under ambiguity, that is, in an environment where ... -
Shelter location and evacuation route assignment under uncertainty: a benders decomposition approach
(INFORMS Inst.for Operations Res.and the Management Sciences, 2018)Shelters are safe facilities that protect a population from possible damaging effects of a disaster. For that reason, shelter location and traffic assignment decisions should be considered simultaneously for an efficient ... -
Technical note-a conic integer optimization approach to the constrained assortment problem under the mixed multinomial logit model
(INFORMS The Institute for Operations Research and the Management Sciences, 2018)We consider the constrained assortment optimization problem under the mixed multinomial logit model. Even moderately sized instances of this problem are challenging to solve directly using standard mixed-integer linear ... -
Mixing challenges for SiO2/polystyrene nanocomposites
(SAGE Publications, 2018)Morphology of a nanocomposite, which has indisputable effects on its properties, is determined by its dynamic and thermodynamic conditions. While physical properties of the components of a nanocomposite as well as the ... -
Evaluation of NO2 column variations over the atmosphere of Kazakhstan using satellite data
(SPIE, 2018)Tropospheric NO2 concentrations obtained from the measurements of the Ozone Monitoring Instrument on board the NASA Aura satellite from 2005 to 2016 were studied to identify major NO2 emission hot spots, trends, and seasonal ... -
Organ transplantation logistics: a case for Turkey
(Springer Verlag, 2018)Logistics is one of the key elements of organ transplantation operations. In this study, maximizing the potential compatible donor-recipient matches within the cold ischemia time bounds (duration that an organ can survive ... -
Influence of diamond tool chamfer angle on surface integrity in ultra-precision turning of singe crystal silicon
(Springer, 2018)Ultra precision diamond machining enables the economical production of freeform optics on infrared materials such as silicon. To produce optics with acceptable surface integrity, it is important to have a good understanding ... -
Combinatorial multi-armed bandit problem with probabilistically triggered arms: a case with bounded regret
(Institute of Electrical and Electronics Engineers, 2018)In this paper, we study the combinatorial multi-armed bandit problem (CMAB) with probabilistically triggered arms (PTAs). Under the assumption that the arm triggering probabilities (ATPs) are positive for all arms, we prove ... -
Post-disaster assessment routing problem
(Elsevier, 2018)In this study, we propose a post-disaster assessment strategy as part of response operations in which effective and fast relief routing are of utmost importance. In particular, the road segments and the population points ...
