Risk analysis - a technique to identify and assess factors that may jeopardize the success of a project or achieving a goal. This technique also helps to define preventive measures to reduce the probability of these factors from occurring and identify countermeasures to successfully deal with these constraints when they develop to avert possible negative effects on the competitiveness of the company, source: http://en.wikipedia.org/wiki/Risk_analysis_%28Business%29, viewed June 16, 2009

Sensitivity analysis is the study of how the variation (uncertainty) in the output of a model can be apportioned, qualitatively or quantitatively, to different sources of variation in the input of a model,  source: http://en.wikipedia.org/wiki/Sensitivity_analysis

Uncertainty analysis is closely related to sensitivity analysis. It is used to examin the reliability of model predictions, by taking into consideration various sources of uncertainty.

Operational research is an interdisciplinary branch of applied mathematics and formal science that uses methods such as mathematical modeling, statistics, and algorithms to arrive at optimal or near optimal solutions to complex problems. It is typically concerned with optimizing the maxima (profit, assembly line performance, crop yield, bandwidth, etc) or minima (loss, risk, etc.) of some objective function. Operations research helps management achieve its goals using scientific methods, source: http://en.wikipedia.org/wiki/Operational_Analysis, viewed June 16, 2009
