Project Portfolio Risk Response Selection Using Bayesian Belief Networks

Risk identification, impact assessment, and response planning constitute three building blocks of project risk management. Correspondingly, three types of interactions could be envisioned between risks, between impacts of several risks on a portfolio component, and between several responses. While the interdependency of risks is a well-recognized issue, the other two types of interactions remai...

Developing an Integrated Simulation Model of Bayesian-networks to Estimate the Completion Cost of a Project under Risk: Case Study on Phase 13 of South Pars Gas Field Development Projects

Objective: The aim of this paper is to propose a new approach to assess the aggregated impact of risks on the completion cost of a construction project. Such an aggregated impact includes the main impacts of risks as well as the impacts of interactions caused by dependencies among them. Methods: In this study, Monte Carlo simulation and Bayesian Networks methods are combined to present a frame...

Improved prediction in Extreme Programming Projects using Bayesian Networks

-Causal models (Bayesian networks) have been used with some success to provide software managers with improved risk assessment and quality assurance methods. It is possible to provide more intuitive and accurate predictions of key project attributes such as effort and defects because they take account of causal (process) factors. To date these methods have largely been restricted to projects us...

Risk Analysis of Operating Room Using the Fuzzy Bayesian Network Model

To enhance Patient’s safety, we need effective methods for risk management. This work aims to propose an integrated approach to risk management for a hospital system. To improve patient’s safety, we should develop flexible methods where different aspects of risk and type of information are taken into consideration. This paper proposes a fuzzy Bayesian network to model and analyze risk in the op...

An Investigation of the Use of BBNs for Project Management

Dynamic models such as Bayesian Networks are of late becoming increasingly popular among the Software Engineering research community. Such models take into account the causal relationship between the variables of a domain, and therefore may provide better solutions to many of the problems in this area. This paper concerns the use of Bayesian Belief Networks (BBNs) in project management. Creatio...
