Probability and risk management

摘要

Risk analysis and risk management for large infrastructure projects using probabilistic methods offer greatrnadvantages for clients and owners. The software developed by the authors,rncombines tools for risk analysis with methods for comprehensive administration and documentation of changes and updates of risks over the various stages from project development to project execution. The most valuable information it provides is the value at risk at any level and stage. Combined with a cost estimate considering uncertainties related to quantities and costs, it provides the owner with a solid basis for budgeting, risk management and cost control.rnThe actual version of RIAAT (Risk Administration and Analysis Tool) contains basic elements to assess the time extension related with risks. Efforts will be made to develop this into an additional module/plug-in linked with RIAAT.
