The answer to every question is not always available to 100% certainty, which can have a profound effect on the analyses. To capture the implications of uncertainty, PortBlue allows users to indicate their level of certainty for every input into a module. Module outputs reflect those certainty levels. At every branch on a decision tree, PortBlue captures and conveys the effect of interim decision uncertainty on overall module certainty, helping you understand the possible implications of compounded uncertainty through the module results.

Uncertainty

PortBlue allows you to indicate your Certainty in the answers to questions on a percentage scale (0% to 100% certain). These certainty levels are captured and conveyed as superscripts in corresponding calculations.
