Risk Simulation Modeling of Engineering Cost Based on MATLAB/SIMULINK

摘要

Based on MATLAB/SIMULINK, the paper has proposed cost risk simulation models separately in accordance with the circumstances of correlation and independence between the influential factors of cost risk. The mean, variance and the risk level under the above-mentioned two circumstances have also been compared with a case study. Also the sensitivity analysis of cost risk has been probed into. The result indicates that the model which takes into account correlation is more objective, and the model which ignores the circumstance of correlation normally under-timates the risk level of project cost.
