Q2. Assume that you will buy an equipment for your project. You must consider two criteria- cost and performance to evaluate two suppliers for selecting one of them. There are three members (i.e., experts) in your purchasing team. The global weight of each member and their evaluations for the suppliers based on cost and performance are as follows: Member Global weight of the Supplier 1 Cost Performance Supplier 2 Cost Performance member Member 1 0.25 1 2 3 4. Member 2 Member 3 0.40 3 2 5 3 0.35 4 5 3 2 Note: The evaluation follows a linguistic scale with a corresponding numerical number from 1 to 5, i.e., very low=1, low-2, medium-3, high =4, and very high= 5, following the fuzzy table below. Fuzzy Triangular numbers and corresponding definitions: Defuzzified number range 0.70 to
