Decision support system approach for cut-and-fill mining

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 ...
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...
Recommendation generation for performance improvement by using cross-organizational process mining Yılmaz, Onur; Yarman Vural, Fatoş Tunay; Department of Computer Engineering (2015) Process mining is a relatively young and developing research area with the main idea of discovering, monitoring and improving processes by extracting information from the event logs. With the increase of cloud computing and shared infrastructures, event logs of multiple organizations are available for analysis where cross-organizational process mining stands with the opportunity for organizations learning from each other. The approach proposed in this study mines process models of organizations and calculat...
