Three Alternative design cars are identified with many criteria to choose according to it, the criteria include; weight, repair, fuel consumption, price and Expected life. Using Score (0 The same, += better, -worse), If you know that: - %3D The current car (Baseline) is heavy weight, very easy to repair, medium fuel consumption, reasonably price and the expected life is 5 years. The First Car Alternative is cheap, difficult to repair, Heavy weight, less fuel consumption, and the expected life is 6 years. The Second Car Alternative is lightweight, expensive, the expected life is 8 years, more fuel consumption, easy to repair. The Third Car Alternative is cheap, the expected life is 4 years, difficult to repair, more consumption fuel, and heavy weight.
