Risk assessment is carried out to understand uncertainties and estimate how they may affect a project. Although there are various studies on alternative methods to quantify risk in projects, limited research exists about how the results are utilized to make sense of project risk by the decision-makers. Probabilistic methods such as Monte Carlo Simulation involve an additional complication as probability is an abstract concept and hard to interpret. We argue that blurred risk pictures as well as lack of familiarity of the users with the concept of probability may lead to misleading interpretations during risk assessments. The aim of this paper is to present the underlying theoretical ideas behind a planned empirical research project with the goal to explore how results of probabilistic risk assessment can be represented in a way that help decision-makers to understand risk in a project and develop visuals that can be used by the decision-makers to see the entire risk picture. Within the study we plan to analyze data from a case study on a mega tunnel project carried out in Turkey, hypothesizing that interactive visualizations may help the user to understand the inputs, outputs and assumptions in quantitative risk models, and help risk managers to understand how project outcomes may change with changes in the risk picture. We hope that the outcomes of the empirical research will allow us to develop better visuals for users to understand the potential scenarios in a project, probability, variation and model uncertainty.

Learning from risks: A tool for post-project risk assessment
Dikmen Toker, İrem; Birgönül, Mustafa Talat; Aouad, G. (2008-12-01)
Risk management (RM) comprises of risk identification, risk analysis, response planning, monitoring and action planning tasks that are carried out throughout the life cycle of a project in order to ensure that project objectives are met. Although the methodological aspects of RM are well-defined, the philosophical background is rather vague. In this paper, a learning-based approach is proposed. In order to implement this approach in practice, a tool has been developed to facilitate construction of a lessons...
Project Cost Benefit and Risk Analysis using Bayesian Networks
Yet, Barbaros; Fenton, Norman; Neil, Martin; Luedeling, Eike; Shepherd, Keith (null; 2015-07-16)
Uncertainty and risks are common elements of all major projects. Yet such uncertainty is rarely effectively calculated when analysing project costs and benefits. This paper presents a Bayesian network (BN) modelling framework to calculate the costs, benefits, and return on investment of a project over a specified time period, allowing for changing circumstances and trade-offs. The framework uses hybrid and dynamic BNs containing both discrete and continuous variables over multiple time stages. The BN calcul...
Identifying and managing risk in mega-projects: the case of automotive test center project in Turkey
Ayvazoğlu, Buğra; Akın Ateş, Melek.; Department of Business Administration (2019)
The issue of risk assessment in projects has attracted considerable attention in both practice and the literature. Although the number of studies investigating large-scale engineering projects (construction, rail system projects, power plants, etc.) has been increasing, majority of them focus on private sector. In this thesis, it is specifically focused on a current, mega-project where both governmental and private organizations participate, namely the Automotive Test Center Project carried out in Turkey. T...
Using Post-Project Reviews for Risk Assessment of Construction Projects
Shokouhi, Pegah; Birgönül, Mustafa Talat; Dikmen Toker, İrem; Department of Civil Engineering (2022-8-26)
Risk management (RM) is about identifying risk factors, analyzing their impacts on project success, and developing management strategies to mitigate them. Learning from previous projects to make better predictions in forthcoming projects is critical for the success of RM activities. Many construction companies conduct post-project reviews (PPRs) to record lessons learned (LL) from projects. However, if these reports do not contain the necessary risk-related information and are not prepared and stored ...
ASSESSMENT OF SUPPLIER RISK FOR COPPER PROCUREMENT
Buzdogan-Lindenmayr, Ezgi; Kara, Guray; Kestel, Sevtap Ayşe (2019-01-01)
Procurement risk management (PRM) requires a good understanding and assessment of all potential risks. As the procurement industry mostly functions globally and the supply-demand chain forms a dependency structure among all interested parties, the quantification of risks related to the suppliers gain importance. This study presents a systematic PRM to evaluate and quantify the risks of a commodity associated to its suppliers. The probabilistic set up using total probability theorem on the information collec...
