FuzzyNumbers (version 0.4-6)

possibilityExceedance: Possibility of exceedance

Description

Determines value of possibility of \(e1>=e2\), the result is from range [0,1]. Value 0 indicates no fulfilment of the operator and 1 indicates complete fulfilment.

Usage

# S4 method for PiecewiseLinearFuzzyNumber,PiecewiseLinearFuzzyNumber
possibilityExceedance(e1, e2)

Arguments

e1

a PiecewiseLinearFuzzyNumber

e2

a PiecewiseLinearFuzzyNumber

Value

Returns a value from range [0,1] indicating the possibility of exceedance of e2 by e1.
