x3 4 Question 1. Assume the bank evaluation problem can be described as follows. Suppose the criteria of evaluating banks can be represented by investment income (xl) in million, number of customers (x2), brand image (x3), and branch numbers (x4). Let the five banks and the corresponding evaluation ratings be described as follow: bank x1 x2 x4 A 2,500 160,000 10 B 2,300 100,000 3,000 150,000 D 3,100 200,000 8 2,800 145,000 Weights 0.4 0.35 0.15 0.1 a.
