A Sustainable Fuzzy Economic Order Quantity Model with Carbon Tax Policy using Pascal Triangular Graded Mean for Pentagonal Fuzzy Numbers

Preservation of environment happens by focusing on sustainable measures taken by each and every business sectors in this modern world. Discussion about certain carbon policies by researchers helps to manage supply chain system under sustainable features. Carbon tax policy is one among them which helps firms to control carbon emission. In this process of controlling and in any case of EOQ system, ambiguous nature in any parameter arises at any instant creating a path way to rectify it. So this model studied a sustainable inventory model under fuzzy perspective as a step to face uncertainty for few parameters. So this model applies Pascal Triangular Graded mean defuzzification approach for pentagonal fuzzy numbers and founds the optimal solution. A Justification is given by using numerical analysis.
