The flowchart begins at the top with a box labeled “Construct the matrix of compiling the alternatives versus criteria for the given”, and a downward arrow leads to the next labeled “Choose the Linguistic variables for the importance weight of each criterion Linguistic variables for the ratings”. A downward arrow arises from this box and points to the following rectangular box labeled “Enter the ratings proposed by the decision Makers for various alternatives with regard to criteria : the importance weight of the criteria assigned by Decision Maker and develop a fuzzy decision matrix and fuzzy weights of their alternatives”, and a downward arrow leads to the next box. The next box is labeled “Construct the fuzzy normalized and fuzzy weighted normalized decision matrix”, and a downward arrow leads to the following rectangular box labeled “Identify the set of positive and negative ideal solutions. Select the fuzzy positive ideal solution (F P I S) and fuzzy negative ideal solution (F N I S)”. A downward arrow then leads to a rectangular box containing the text “Calculate similarly degree of each candidate to F P I S and F N I S”. Another downward arrow points to a rectangular box labeled “Calculate Closeness Coefficient (C C i)”, and a downward arrow then leads to the next rectangular box labeled “Rank the preference order of each alternative”. A downward arrow points from this box to a diamond-shaped decision box that reads “Does the highest ranking option fit with Best practicable and economical option”. From this decision box, the left branch labeled “No” loops back upward and points to the downward arrow arising from “Construct the matrix of compiling the alternatives versus criteria for the given”. The downward branch from the diamond box labeled “Yes” leads downward to an oval labeled “stop”.Flow diagram of Fz–Ts methodology. Source – Authors’ own work
