The uncertainty surrounding the total cost and according to the Tiwari and AL 1987 model and ba sed on its own membership functions. Finally, we have used the LINGO software to solve this mathematical model and the optimal solution is obtainedotherMathematica l model, decision making, fuzzy g oalpro gramm ing , membership functions , decisionThesis
