A decision support tool for conceptual site model development at contaminated sites
Büyüker, Beril; Ünlü, Kahraman; Department of Environmental Engineering (2009)
A conceptual site model (CSM) is simply a description of the environmental conditions at a contaminated site and surrounding area, which provides all interested parties with a vision of the site. CSM mainly identifies the source-pathway‐ receptor linkage to guide for effective site characterization, risk assessment and remedial investigations. Development of CSM is complicated because it is ‘case specific’ and there is no single route to follow during decision making concerning the contaminated site. Moreov...
A Fuzzy delay assessment tool for construction projects
Ghaziani, Aydin; Dikmen Toker, İrem; Birgönül, M Talat; Department of Civil Engineering (2012)
It is a known fact that construction projects do not often complete on time due to several reasons related with the unexpected changes in the project conditions, external factors or performance of project participants. Since construction projects are unique and limited information is available at the beginning of the projects, prediction of delays is a difficult task. However, if the delays can be assessed at the early stages, their impacts might be minimized, some of the delays can even be eliminated. This...
A decision support tool for feasibility assessment of hydro electrical power plant projects
Ercan, Noyan; Birgönül, Mustafa Talat; Dikmen Toker, İrem; Department of Civil Engineering (2011)
The objective of this thesis is to develop a decision support tool to assess the feasibility of a hydro electrical power plant (HEPP) investment option by estimating its profitability under various scenarios. The decision support tool may help the decision makers to understand critical parameters that affect the internal rate of return (IRR) of a HEPP investment, create realistic scenarios by assigning different values to these parameters and monitor profitability under various scenarios. The information an...
A case-based decision support tool for bid mark-up estimation of international construction projects
Dikmen Toker, İrem; Birgönül, Mustafa Talat (2007-11-01)
The bid mark-up estimation is an unstructured decision problem that is usually solved by intuition. The aim of this paper is to present a decision support tool so that bid mark-up values may be estimated in a more systematic way. For this purpose, various factors that may affect the level of risk, opportunity and competition in a project option have been identified. Using the 95 cases obtained from the Turkish contractors working in international markets, a case-based reasoning model (CBR) has been develope...
A knowledge-based risk mapping tool for cost estimation of international construction projects
Yildiz, Acelya Ecem; Dikmen Toker, İrem; Birgönül, Mustafa Talat; Ercoskun, Kerem; Alten, Selcuk (Elsevier BV, 2014-07-01)
Effective risk assessment and management is critical for success in international construction projects. This paper proposes a knowledge-based risk mapping tool for systematically assessing risk-related variables that may lead to cost overrun in international markets. The tool uses an ontology that relates risk and vulnerability to cost overrun [1] and a novel risk-vulnerability assessment methodology [2] to estimate potential risk paths that may emerge in international construction projects. The tool has b...
