A calculation method for solving fuzzy arithmetic equations with triangular norms

The authors apply a previously developed calculation method using a digital representation to obtain an approximate solution to a fuzzy arithmetic equation. A t-norm and a phi -operator which is defined in connection with a given t-norm are summarized. Nonstandard operations based on the inf- phi co...

Description
Summary:The authors apply a previously developed calculation method using a digital representation to obtain an approximate solution to a fuzzy arithmetic equation. A t-norm and a phi -operator which is defined in connection with a given t-norm are summarized. Nonstandard operations based on the inf- phi convolution are discussed as a solution for the fuzzy arithmetic equation. Formulas involving the solution of the equations as well as the classifications of t-norms and phi -operators that are necessary for applying the formulas are presented. Some numerical examples are included.< >
