Stochastic linear quadratic control problem of switching systems with constraints
(Springer International Publishing Ag, 2016)This paper is devoted to the optimal control problem for stochastic linear switching systems with a quadratic cost functional. A necessary and sufficient condition of optimality for mentioned linear control systems under ... -
Fuzzy multi-objective decision model for calibration supplier selection problem
(Pergamon-Elsevier Science LTD, 2016)Quality products and competitively priced services are crucial in today's global markets. To provide quality at an acceptable price, companies seek out not only raw material and product suppliers but also calibration ... -
A Representation Theorem for Bishop-Phelps Cones
(Yokohama Publishers, 2017)The paper presents a theorem for representation a given cone as a Bishop-Phelps cone in normed spaces and studies interior and separation properties for Bishop-Phelps cones. The representation theorem is formulated in the ... -
The appropriateness of today's airport security measures in safeguarding airline passengers
(Palgrave Macmillan LTD, 2017)The aim of this study is to find out whether the user anxiety created by today's airport security measures changes depending on some individual user characteristics. To this end, 904 passengers were surveyed in the sterile ... -
Six Sigma experience as a stochastic process
(Taylor & Francis Inc, 2017)This study empirically investigates the states of Six Sigma from a stochastic point of view. By the means of an advanced survey, 97 respondents are asked to rate the effect of Six Sigma on different performance categories, ... -

(2017)Dünya'da her yıl milyonlarca insan iş kazaları nedeniyle yaralanmakta, yaşamını yitirmekte ya da işle ilgili meslek hastalığına yakalanmaktadır. İş kazalarının, meslek hastalıklarının ve olay sonucu ortaya çıkan maliyetlerin ... -
Coordinated pricing and inventory decisions for perishable products
(Springer, 2017)We investigate the problem of jointly determining the optimal pricing and inventory replenishment strategy for a deterministic perishable inventory system in which demand is time and price dependent. The inventory is also ... -
Coordinated dispatching and acquisition fee decisions for a collection center in a reverse supply chain
(Pergamon-Elsevier Science LTD, 2017)Collection, centers play an important role for sustainable development in closed-loop supply chains by managing the collection activities of end-of-life (EOL) products and presenting them back to the economy. In this study, ... -
A coradiant based scalarization to characterize approximate solutions of vector optimization problems with variable ordering structures
(Elsevier Science BV, 2017)This paper investigates some properties of approximate efficiency in variable ordering structures where the variable ordering structure is given by a special set valued map. We characterize epsilon-minimal and epsilon- ... -
Coradiant sets and -efficiency in multiobjective optimization
(Springer, 2017)This paper studies -efficiency in multiobjective optimization by using the so-called coradiant sets. Motivated by the nonlinear separation property for cones, a similar separation property for coradiant sets is investigated. ... -
