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. ... -
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 ... -
Comparison of Some Scalarization Methods in Multiobjective Optimization: Comparison of Scalarization Methods
(Malaysian Mathematical Sciences Soc, 2019)The paper presents an analysis, characterizations and comparison of six commonly used scalarization methods in multiobjective optimization. The properties of these methods are investigated with respect to the basic ... -
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- ... -
A generalization of a theorem of Arrow, Barankin and Blackwell to a nonconvex case
(Taylor & Francis LTD, 2016)The paper presents a generalization of a known density theorem of Arrow, Barankin, and Blackwell for properly efficient points defined as support points of sets with respect to monotonically increasing sublinear functions. ... -
Heuristic algorithms for the single allocation <bold>p</bold>-hub center problem with routing considerations
(Springer, 2019)Given a network with n nodes, the p-hub center problem locates p hubs and allocates the remaining non-hub nodes to the hubs in such a way that the maximum distance (or time) between all pairs of nodes is minimized. Commonly, ... -
Single allocation p-hub median location and routing problem with simultaneous pick-up and delivery
(Pergamon-Elsevier Science LTD, 2017)We introduce the single allocation p-hub median location and routing problem with simultaneous pick-up and delivery based on observations from real life hub networks. The aim of our problem is to minimize the cost of ... -
U-Type Assembly Line Balancing With Ergonomic Factors for Balance Stability
(Gazi University, Fac Engineering Architecture, 2012)In this paper, we present a new mathematical model of U-type assembly line balancing problem based on the performance factors of the operators, the amount of energy used and incompatibility between the tasks. Many researchers ... -
Research determining issues on the administrative success of security services at civil airports in Turkey
(Palgrave Macmillan LTD, 2018)The aim of this study is to identify problems affecting the managerial success of airport security services in Turkey and to develop solutions for these problems. Semi-structured interviews were conducted with a total of ... -
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 ... -
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 ... -
Evaluating the Packing Process in Food Industry Using Fuzzy X ~ and S ~ Control Charts
(Atlantis Press, 2011)The fuzzy set theory addresses the development of concepts and techniques for dealing with uncertainty or impression conditions. If the collected data from a process include vagueness due to human subjectively or measurement ... -
Construction of a fuzzy QFD failure matrix using a fuzzy multiple-objective decision model
(Taylor & Francis LTD, 2010)Global competition has forced companies to consider increasing quality and decreasing all costs, including quality costs. When constructing the quality plan for both the incoming raw materials and the manufacturing process, ... -
The effect of inspection error on quality and producer losses: the case of nominal-the-best type quality characteristic and rework
(Inderscience Enterprises LTD, 2013)In this study, the effect of inspection error (IE) on quality and producer losses is investigated for a nominal-the-best type quality characteristic determined by a manufacturing process centre with a separate rework unit. ... -
Numerical optimization of a fin-tube gas to liquid heat exchanger
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2012)The influence of plate fin, fin tube and protrusion parameters on heat transfer and pressure drop characteristics of a finned tube gas to liquid heat exchanger is examined in this study. The optimization of plate fin, fin ... -
Effective use of quality function deployment and Kansei engineering for product planning with sensory customer requirements: A plain yogurt case
