Developing growing hierarchical structures for decision making

A new systematic and flexible method for developing hierarchical decision-making models BELDEK, ULAŞ; Leblebicioğlu, Mehmet Kemal (2015-01-01) The common practice in multilevel decision-making (DM) systems is to achieve the final decision by going through a finite number of DM levels. In this study, a new multilevel DM model is proposed. This model is called the hierarchical DM (HDM) model and it is supposed to provide a flexible way of interaction and information flow between the consecutive levels that allows policy changes in DM procedures if necessary. In the model, in the early levels, there are primary agents that perform DM tasks. As the le...
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 hierarchical decision support system for workforce planning in medical equipment maintenance services Cihangir, Çiğdem; Bayındır, Zeynep Pelin; Tan, Tarkan; Department of Industrial Engineering (2010) In this thesis, we propose a hierarchical level decision support system for workforce planning in medical equipment maintenance services. In strategic level, customer clusters and the total number of field engineers is determined via a mixed integer programming and simulation. In MIP, we aim to find the minimum number of field engineers. Afterwards, we analyze service measures such as response time via simulation. In tactical level, quarterly training program for the field engineers is determined via mixed ...
Development of a decision support system for employee scheduling problem in hospitality sector: a case study in a Turkish firm Ünsal, Emre Ber; Karakaya, Gülşah; Department of Business Administration (2019) Employee scheduling problems arise in many environments where a group of employees works together. This study deals with the employee scheduling problem in hospitality sector where the employees are supposed to greet and communicate with the guests in the events. The content of the problem is assigning different skilled employees to the events which have different complexity and difficulty levels. We propose a solution method which aims to create better employee schedules in terms of cost and quality of the...
