Optimal bundle formation and pricing of two products with limited stock
(2009)In this study, we consider the stochastic modeling of a retail firm that sells two types of perishable products in a single period not only as independent items but also as a bundle. Our emphasis is on understanding the ... 
Optimal control of a twostage stochastic hybrid manufacturing system with Poisson arrivals and exponential service times
(IEEE, 2005)Extending earli'er work on singlestage stochastic hybrid system models, we consider a twostage stochastic hybrid system where the job arrivals are represented through a Poisson process, and the service times required to ... 
Optimal control of singlestage hybrid systems with poisson arrivals and deterministic service times
(IEEE, 2005)We tackle an optimal control problem for a singlestage hybrid system with Poisson arrivals and deterministic service times. In our setting, not only that the optimization problem is nonconvex and nondifferentiable, but ... 
Optimal hybrid control of a twostage manufacturing system
(IEEE, 2006)We consider a twostage serial hybrid system for which the arrival times are known and the service times are controllable. We derive some optimal sample path characteristics, in particular, we show that no buffering is ... 
Optimal multiperiod consumption and investment with shortsale constraints
(Elsevier, 201403)This article examines agents’ consumptioninvestment problem in a multiperiod pure exchange economy where agents are constrained with the shortsale of statedependent risky contingent claims. In equilibrum, agents ... 
Optimal oblivious routing under linear and ellipsoidal uncertainty
(Springer, 2008)In telecommunication networks, a common measure is the maximum congestion (i.e., utilization) on edge capacity. As traffic demands are often known with a degree of uncertainty, network management techniques must take into ... 
Optimal order quantity and pricing decisions in singleperiod inventory systems
(1991)In this paper, we consider simultaneous pricing and procurement decisions associated with a oneperiod pure inventory model under deterministic or probabilistic demand. We investigate the necessary and sufficient conditions ... 
Optimal pickup point location on material handling networks
(1989)The optimal location of a pickup point on a material handling network is considered. The pickup point is defined as the material exchange point between the material handling system (MHS) and a station. The problem is defined ... 
Optimal stopping problems for asset management
(2012)An asset manager invests the savings of some investors in a portfolio of defaultable bonds. The manager pays the investors coupons at a constant rate and receives a management fee proportional to the value of the portfolio. ... 
Optimal streaming of a single job in a twostage flow shop
(Elsevier, 19981001)Lot streaming is moving some portion of a process batch ahead to begin a downstream operation. The problem to be considered in this paper is the following: a single job consisting of U units is to be processed on two ... 
Optimization of a flow shop system of initially controllable machines
(IEEEInstitute of Electrical and Electronics Engineers, 20081222)We consider an optimization problem for deterministic flow shop systems of traditional machines with service costs penalizing small service times. A regular completiontime cost is also included so as to complete jobs ... 
Optimization of hybrid energy systems with pumped hydro storage: a case study for Turkey
(Gazi Üniversitesi MühendislikMimarlık, 2019)There is a need for energy models that include renewable energy sources to reduce the role of fossil fuels in electricity generation. However, renewable energy sources are intermittent and cannot be predicted precisely. ... 
Optimization of schedule robustness and stability under random machine breakdowns and processing time variability
(Taylor & Francis, 2010)In practice, scheduling systems are subject to considerable uncertainty in highly dynamic operating environments. The ability to cope with uncertainty in the scheduling process is becoming an increasingly important issue. ... 
Optimization of schedule stability and efficiency under processing time variability and random machine breakdowns in a job shop environment
(John Wiley & Sons15206750 (online), 2012)The ability to cope with uncertainty in dynamic scheduling environments is becoming an increasingly important issue. In such environments, any disruption in the production schedule will translate into a disturbance of the ... 
Optimization of transportation requirements in the deployment of military units
(Elsevier, 2007)We study the deployment planning problem (DPP) that may roughly be defined as the problem of the planning of the physical movement of military units, stationed at geographically dispersed locations, from their home bases ... 
An ordering (enumerative) algorithm for nonlinear 01 programming
(Kluwer Academic Publishers, 1994)In this paper, a new algorithm to solve a general 01 programming problem with linear objective function is developed. Computational experiences are carried out on problems where the constraints are inequalities on ... 
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 donorrecipient matches within the cold ischemia time bounds (duration that an organ can survive ... 
OSPF routing with optimal oblivious performance ratio under polyhedral demand uncertainty
(Springer, 2010)We study the best OSPF style routing problem in telecommunication networks, where weight management is employed to get a routing configuration with the minimum oblivious ratio. We consider polyhedral demand uncertainty: ... 
Overdetermined systems of linear equations
(Springer, 2009) 
An overview of design and operational issues of kanban systems
(Taylor & Francis, 1999)We present a literature review and classification of techniques to determine both the design parameters and kanban sequences for justintime manufacturing systems. We summarize the model structures, decision variables, ...
