In decision making problems that contain multiple and conflicting objectives, it is not an easy and straightforward task to determine the most preferred solution of a decision maker. In this study, an interactive method is proposed to converge to the most preferred solution of the decision maker. The proposed method elicits preference information from the decision maker in consecutive iterations and reduces the solution space accordingly. The decision maker evaluates a limited number of solutions in each iteration and makes decisions that impose low cognitive burden. These decisions are modeled by a weighted L alpha function, a preference function that is flexible and compatible with behavior of real decision makers. To enhance the efficiency of the proposed method, the solutions presented for evaluation in each iteration are determined with the help of a filtering approach. Data from annual university rankings of Times Higher Education is used to assess the performance of the proposed method. Experiments are carried out with three different university sets evaluated with respect to five criteria. The results show that the proposed method successfully converges to the most preferred solution.

A parallel between regret theory and outranking methods for multicriteria decision making under imprecise information Ozerol, Gul; Karasakal, Esra (Springer Science and Business Media LLC, 2008-08-01) Incorporation of the behavioral issues of the decision maker (DM) is among the aspects that each Multicriteria Decision Making (MCDM) method implicitly or explicitly takes into account. As postulated by regret theory, the feelings of regret and rejoice are among the behavioral issues associated with the entire decision making process. Within the context of MCDM, the DM may feel regret, when the chosen alternative is compared with another one having at least one better criterion value. PROMETHEE II is a wide...
An Interactive partitioning approach for multiobjective decision making under a general monotone utility function Karasakal, Esra (2013-09-01) We develop an interactive partitioning approach for solving the multiobjective decision making problem of a decision maker (DM) who has an implicit general monotone utility function. The approach reduces feasible solution space using the DM's preferences. Hypothetical solutions called partition ideals (PIs) that dominate portions of the efficient frontier are generated and those that are inferior to a feasible solution are used to eliminate the dominated regions. We investigate the issues in representation ...
A decision support framework for project sponsors in the planning stage of build-operate-transfer (BOT) projects Dikmen Toker, İrem; Birgönül, Mustafa Talat (2000-10-01) Every decision-making problem is oriented towards the selection of the correct strategies for achieving objectives, and depends on the assumptions associated with different scenarios. Project planning in a buildoperate-transfer (BOT) project is a complicated decision-making problem because the model has a complex financial and organizational structure which is influenced also by the socio-economic environment in a country. A decision support framework is reported, as used in the planning stage of a hydropow...
Mapping Uncertainty for Risk and Opportunity Assessment in Projects Qazi, Abroon; Dikmen Toker, İrem; Birgönül, Mustafa Talat (Informa UK Limited, 2019-01-01) Risk management is deemed as a critical process toward achieving the objectives of any project. A number of tools and techniques have been developed to help project managers reduce the risk involved in complex projects as risk is generally perceived as a negative event. However, uncertainty, which may lead to risk events may well result in opportunities. With the main aim of managing both risk and opportunity within an interdependent setting of interacting project uncertainties, we present a new thinking, c...
A unifying grid approach for solving potential flows applicable to structured and unstructured grid configurations Cete, A. Ruhsen; Yuekselen, M. Adil; Kaynak, Uenver (Elsevier BV, 2008-01-01) In this study, an efficient numerical method is proposed for unifying the structured and unstructured grid approaches for solving the potential flows. The new method, named as the "alternating cell directions implicit - ACDI", solves for the structured and unstructured grid configurations equally well. The new method in effect applies a line implicit method similar to the Line Gauss Seidel scheme for complex unstructured grids including mixed type quadrilateral and triangle cells. To this end, designated al...
