A New Idea to Evaluate Networking Problem and MCGDM Problem in Parametric Interval Valued Pythagorean Arena

In this article, the concept of parametric interval valued Pythagorean number (PIVPN) has been introduced, which is an extended version (PN). Here, a new score and accuracy function have innovated in PIVPN environment along with De-Pythagorean value concept. The tool techniques fruitfully applied to two realistic problems, namely networking critical path model (CPM) problem multicriteria group decision making (MCGDM) problem. order solve MCGDM problem, we prepared Parametric Interval Weighted Arithmetic Mean Operator (PIVPWAMO) Geometric (PIVPWGMO) operator environment. Finally, sensitivity analysis industrious comprehensive numerical simulations performed identify reliability, efficiency, usefulness novel work. shown that PIVPNs are more well-organized representation grip real-life they can handle inconsistent conditions better compatible way comparison other existing methods.
