A bi-criteria approach to scheduling in the face of uncertainty: Considering robustness and stability simultaneously
Selcuk, Gören; Sabuncuoĝlu, Ihsan (Nova Science Publishers, Inc., 2014)It is possible to scrutinize impacts of uncertainty on schedules from two different perspectives. The flrst one has to do with the fact that schedules are required to main- tain high performance in the face of uncertainty. ... -
Computation of polarized metrized graph invariants by using discrete laplacian matrix

Contraction Formulas for the Kirchhoff and Wiener Indices
Cinkir, Zubeyir (UNIV KRAGUJEVAC, FAC SCIENCEPO BOX 60, RADOJA DOMANOVICA 12, KRAGUJEVAC 34000, SERBIA, 2016)We relate the Kirchhoff index with some other metrized graph invariants. We establish several contraction formulas for the Kirchhoff index. We use these contraction formulas and certain edge densities to give new upper and ... -
Disutility Entropy in Multi-attribute Utility Analysis
Sutcu, Muhammed (PERGAMON-ELSEVIER SCIENCE LTD, 2022)In this paper, we present an alternative formulation of utility entropy called disutility entropy. Previous entropy measurements in the literature use utility density function in maximum entropy formulations. Also, in ... -
Effective resistances and Kirchhoff index of ladder graphs
Cinkir, Zubeyir (SPRINGERONE NEW YORK PLAZA, SUITE 4600 , NEW YORK, NY 10004, UNITED STATES, 2016)We explicitly compute the effective resistances between any two vertices of a ladder graph by using circuit reductions. Using our findings, we obtain explicit formulas for Kirchhoff index of a ladder graph. Comparing our ... -
Families of Metrized Graphs with Small Tau Constants
Cinkir, Zubeyir (SPRINGER BASEL AGPICASSOPLATZ 4, BASEL 4052, SWITZERLAND, 2016)Baker and Rumely's tau lower bound conjecture claims that if the tau constant of a metrized graph is divided by its total length, this ratio must be bounded below by a positive constant for all metrized graphs. We construct ... -
A Framework to Incorporate Decision-Maker Preferences Into Simulation Optimization to Support Collaborative Design
Goren, Selcuk; Baccouche, Ahlem; Pierreval, Henri (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC445 HOES LANE, PISCATAWAY, NJ 08855-4141, 2017)In this paper, we are concerned with the use of simulation optimization to handle collaborative design problems where more than one decision-maker is involved. We assume that the designers cannot enumerate all their ... -
