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 ... 
On Khachiyan's algorithm for the computation of minimumvolume enclosing ellipsoids
(Elsevier, 2007)Given A {colon equals} { a1, ..., am } ⊂ Rd whose affine hull is Rd, we study the problems of computing an approximate rounding of the convex hull of A and an approximation to the minimumvolume enclosing ellipsoid of A. ... 
On multicriteria chanceconstrained capacitated singlesource discrete facility location problems
(Elsevier, 2018)This work aims at investigating multicriteria modeling frameworks for discrete stochastic facility location problems with single sourcing. We assume that demand is stochastic and also that a service level is imposed. This ... 
On Newton's method for Huber's robust Mestimation problems in linear regression
(Springer Netherlands, 1998)The Newton method of Madsen and Nielsen (1990) for computing Huber's robust Mestimate in linear regression is considered. The original method was proved to converge finitely for full rank problems under some additional ... 
On pricing of perishable assets with menu costs
(Elsevier, 200910)We consider dynamic pricing of perishable assets in the presence of pricesensitive renewal demand processes. Unlike the existing works in the literature, we explicitly incorporate nonnegligible price change costs which ... 
On pseudo symmetric monomial curves
(Taylor & Francis, 20171215)We study monomial curves, toric ideals and monomial algebras associated to 4generated pseudo symmetric numerical semigroups. Namely, we determine indispensable binomials of these toric ideals, give a characterization ... 
On robust meanvariance portfolios
(Taylor and Francis, 2016)We derive closedform portfolio rules for robust mean–variance portfolio optimization where the return vector is uncertain or the mean return vector is subject to estimation errors, both uncertainties being confined to an ... 
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 ... 
On robust solutions to linear least squares problems affected by data uncertainty and implementation errors with application to stochastic signal modeling
(Elsevier, 2004)Engineering design problems, especially in signal and image processing, give rise to linear least squares problems arising from discretization of some inverse problem. The associated data are typically subject to error in ... 
On semidefinite bounds for maximization of a nonconvex quadratic objective over the ℓ1 unit ball
(E D P Sciences, 2006)We consider the nonconvex quadratic maximization problem subject to the ℓ1 unit ball constraint. The nature of the l1 norm structure makes this problem extremely hard to analyze, and as a consequence, the same difficulties ... 
On separating cover inequalities for the multidimensional knapsack problem
(Elsevier, 200706)We propose a simple and a quite efficient separation procedure to identify cover inequalities for the multidimensional knapsack problem. It is based on the solution of a conventional integer programming model. Solving ... 
On testing independence with right truncated data
(Elsevier, 199712)Inference with bivariate data gained considerable interest recently, See eg.[1],[10],[12]. All of these studies howrver consider estimation of the bivariate distribution function under various bivariate censoring models. ... 
On the accuracy of uniform polyhedral approximations of the copositive cone
(Taylor & Francis, 2012)We consider linear optimization problems over the cone of copositive matrices. Such conic optimization problems, called copositive programs, arise from the reformulation of a wide variety of difficult optimization problems. ... 
On the consistency of a twosample matching test
(Taylor & Francis, 1996)Let {X k} and {Y k}, 1 ≤ k ≤n be the order statistics of independent random samples from continuous distribution function F and G respectively. To test the null hypothesis H 0 : G = F, known, against the alternative H 1 : ... 
On the distribution of throughput of transfer lines
(Palgrave Macmillan, 2000)Transfer lines simply characterise the interrelationship of manufacturing stages with their buffers and they are used to model the key features of such manufacturing environments with simplifying assumptions. There is a ... 
On the Hajek projection for truncated and censored data
(Scientific Publishers, 1993)Large sample properties of the productlimit estimators for truncated or censored data are usually achieved via the empirical cumulative hazard function estimators. Hajek projection of the empirical cumulative hazard ... 
On the minimum volume covering ellipsoid of ellipsoids
(Society for Industrial and Applied Mathematics, 2006)Let S denote the convex hull of m fulldimensional ellipsoids in ℝn. Given ε > 0 and δ > 0, we study the problems of computing a (1 + ε)approximation to the minimum volume covering ellipsoid of S and a (1 + δ)nrounding ... 
On the modeling of CO2 EUA and CER prices of EUETS for the 2008–2012 period
(John Wiley and Sons, 2016)Increased consumption of fossil fuels in industrial production has led to a significant elevation in the emission of greenhouse gases and to global warming. The most effective international action against global warming ... 
On the optimality of the greedy solutions of the general knapsack problems
(Taylor & Francis, 1992)In this paper we submit a unified discussion of some closely related results which were achieved independently in number theory and integer programming, and we partially generalize them. In the unified discussion we treat ...
