Newsboy inventory problem [reprint]
(John Wiley & Sons, 2010)A definition and classical formulation of the newsboy inventory model as a profit maximization problem is provided. The structure of the optimal stocking policy is given. Alternative formulations of meanvariance, downside ... 
Newsvendor competition under asymmetric cost information
(Elsevier B.V., 2018)We study the newsboy duopoly problem under asymmetric cost information. We extend the Lippman and McCardle (1997) of competitive newsboy to the case where the two firms are privately informed about their unit costs. The ... 
Newton's method for linear inequality systems
(Elsevier, 1998)We describe a modified Newton type algorithm for the solution of linear inequality systems in the sense of minimizing the ℓ2 norm of infeasibilities. Finite termination is proved, and numerical results are given. © 1998 ... 
Noncooperative joint replenishment under asymmetric information
(Elsevier, 2013)We consider jointly replenishing n exante identical firms that operate under an EOQ like setting using a noncooperative game under asymmetric information. In this game, each firm, upon being privately informed about its ... 
Nonidentical parallel CNC machine scheduling
(Taylor & Francis, 2003)In this study, we solve the nonidentical parallel CNC machine scheduling problem. We have two objectives: minimizing the manufacturing cost (comprising machining, nonmachining and tooling costs) and minimizing the total ... 
Nonlinear pricing by convex duality
(Elsevier, 2015)We consider the pricing problem of a riskneutral monopolist who produces (at a cost) and offers an infinitely divisible good to a single potential buyer that can be of a finite number of (single dimensional) types. The ... 
Nonparametric estimation of hazard functions and their derivatives under truncation model
(Kluwer Academic Publishers, 1993)Nonparametric kernel estimators for hazard functions and their derivatives are considered under the random left truncation model. The estimator is of the form of sum of identically distributed but dependent random variables. ... 
A note on "continuous review perishable inventory systems: models and heuristics"
(2003)In a recent paper, Lian and Liu (2001) consider a continuous review perishable inventory model with renewal arrivals, batch demands and zero lead times. However, the main analytical result they provide holds only for some ... 
A note on a polynomial time solvable case of the quadratic assignment problem
(Elsevier, 2006)We identify a class of instances of the KoopmansBeckmann form of the Quadratic Assignment Problem that are solvable in polynomial time. This class is characterized by a path structure in the flow data and a grid structure ... 
A note on robust 01 optimization with uncertain cost coefficients
(Springer, 2004)Based on the recent approach of Bertsimas and Sim (2004, 2003) to robust optimization in the presence of data uncertainty, we prove an easily computable and simple bound on the probability that the robust solution gives ... 
Note on the backroom effect in retail operations
(WileyBlackwell, 2015)Eroglu et al. (2013) study a retailer with limited shelf capacity and a backroom. They study a continuous review (r, q) ordering policy with a known order quantity, q. Assuming that backorders can be satisfied from the ... 
A note on the withincell layout problem based on operation sequences
(Taylor & Francis, 1996)The existing studies in the literature usually ignore the withincell layout problem while forming part families and manufacturing cells. A new approach is proposed to solve the partfamily and machinecell formation problem ... 
A novel optimization algorithm for video placement and routing
(Institute of Electrical and Electronics Engineers, 2006)In this paper, we propose a novel optimization algorithm for the solution of the video placement and routing problem based on Lagrangean relaxation and decomposition. The main contribution can be stated as the use of integer ... 
A novel technique for a linear system of equations applied to channel equalization
(IEEE, 2009)In many inverse problems of signal processing the problem reduces to a linear system of equations. Accurate and robust estimation of the solution with errors in both measurement vector and coefficient matrix is a challenging ... 
OM forum: innovative online platforms: research opportunities
(INFORMS: Institute for Operations Research and the Management Sciences, 2020)Economic growth in many countries is increasingly driven by successful startups that operate as online platforms. These success stories have motivated us to define and classify various online platforms according to their ... 
On closedform solutions of a resource allocation problem in parallel funding of R & D projects
(Elsevier, 2000)In order to reduce the risk of complete failure, research managers often adopt a parallel strategy by simultaneously funding several R&D activities and several research teams within each activity. The parallel strategy ... 
On connected Boolean functions
(Elsevier, 1999)A Boolean function is called (co)connected if the subgraph of the Boolean hypercube induced by its (false) true points is connected; it is called strongly connected if it is both connected and coconnected. The concept ... 
On envyfree perfect matching
(Elsevier, 2019)Consider a situation in which individuals –the buyers –have different valuations for the products of a given set. An envyfree assignment of product items to buyers requires that the items obtained by every buyer be ... 
On explicit solutions of a twoechelon supply chain coordination game
(Springer Verlag, 2018)A contracting game under asymmetric information specific to twoechelon supply chain coordination between a retailer of unknown type and a supplier is studied. When the parameter which is private information to the retailer ... 
On extracting maximum stable sets in perfect graphs using Lovász's theta function
(Springer, 2006)We study the maximum stable set problem. For a given graph, we establish several transformations among feasible solutions of different formulations of Lovász's theta function. We propose reductions from feasible solutions ...
