Description |
Risk Calc performs a what-if analysis using classical interval analysis and its generalisation, fuzzy arithmetic. Standard mathematical functions are supported. Allows: definition of variables, loops, conditionals and user defined functions to evaluate complex expressions. Analyses may include real numbers, intervals and fuzzy numbers. Fuzzy numbers may be defined as triangular or trapezoidal distributions, or drawn graphically with the mouse, or estimated automatically from empirical observations. The results are displayed graphically or numerically. Documentation includes tutorial on fuzzy numbers and possibility arithmetic. |
