Necessity of strict exceedance
Description
Determines value of necessity 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 signature
## 'PiecewiseLinearFuzzyNumber,PiecewiseLinearFuzzyNumber'
necessityStrictExceedance(e1, e2)
Arguments
e1 |
a PiecewiseLinearFuzzyNumber |
e2 |
a PiecewiseLinearFuzzyNumber |
Value
Returns a value from range [0,1] indicating the strict necessity of exceedance of e2 by e1.
