Decision support for multi-attribute auctions
Karakaya, Gülşah; Köksalan, Murat; Department of Industrial Engineering (2013)
In this study, we address multi-attribute, multi-item auction problems. In multi-attribute auctions there are additional attributes to the price and the comparison of bids is not straightforward. In multi-item auctions which are also known as combinatorial auctions, it is not so trivial to determine the winning bidders. We develop an auction decision support system (ADSS) that supports sellers to bid on multiple items. We demonstrate our approach in a multi-attribute, multi-item reverse auction setting. The...
Decision support system for Warfarin therapy management using Bayesian networks
Yet, Barbaros; Raharjo, Hendry; Lifvergren, Svante; Marsh, William; Bergman, Bo (2013-05-01)
Warfarin therapy is known as a complex process because of the variation in the patients' response. Failure to deal with such variation may lead to death as a result of thrombosis or bleeding. The possible sources of variation such as concomitant illnesses and drug interactions have to be investigated by the clinician in order to deal with the variation. This paper describes a decision support system (DSS) using Bayesian networks for assisting clinicians to make better decisions in Warfarin therapy managemen...
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 ...
A Life cycle costing based decision support tool for cost-optimal energy efficient design and/or refurbishments
Emekci, Şeyda; Tanyer, Ali Murat; Department of Architecture (2018)
In construction sector, deciding on building investment / refurbishments can be a complex process because it involves multiple criteria and generally conflicting objectives. For this reason, in the early phase, it is necessary to carry out an analysis that can enhance the predictability of these decisions taken, determine the optimum points of conflicting decisions and at the same time increase the social, environmental and economic sustainability. In the analysis, the total cost incurred building life cycl...
Decision Support Tool for the Quantification of Fault Rates in Construction Fall Accidents
Birgönül, Mustafa Talat; Dikmen Toker, İrem (null; 2005-09-09)
After the occurrence of construction work accidents, expert witness reports received with the aim of quantifying fault rates among parties, play an important role on the court's final decision. However, conflicting fault rates assigned by different expert witness groups for the similar cases are quite common practice, leading to unnecessary and iterative objections raised by the related parties until a consensus among reports has been reached. This unfavourable situation mainly originates due to subjectivit...
