1. A Jeep manufacturer uses a special control device in each Jeep he produces. Four alternative methods A, B, C, D can be used to detect and avoid a faulty device. To detect the fault, the devices should go through four testing machines M1, M2, M3, and M4. The corresponding payoffs are shown in table below: M M3 M4 20*a 100+b 50+2*a M2 A -150 B 400 0 200 0 -50*b 200 0 100 D 0 300 + a + b 300 0 Calculate the loss table of the above payoff table. Suggest a decision for him as per the minimax regret criteria. (15 marks)
