Question
Using the following data, complete an AHP. What navigation system minimizes the navigation error? A cargo aircraft is being designed to operate in different parts of the world where external navigation aids vary in quality. The manufacturer has identified five areas where the aircraft is likely to fly and the likelihood that the aircraft will be in each area. The aircraft will be in Areas 1-5 with the frequency given in the following table. The table also gives the five navigation systems under consideration, N_1, N_2, N_3, N_4, and N_5.The manufacturer has estimated the typical navigation errors to be expected in each area and these are shown in the table. Navigation errors are in nautical miles (nm). Small navigation errors are good; large navigation errors are not good. Which system(s) will maximize the probability of achieving a navigation error of 0.10 nm or less? What is the probability of achieving this navigation error? Which choice would be made by using the most probable future criterion?Explanation / Answer
a) After calculating the navigation error of all the systems in each area, N4 system has the least error. hence ans is N4
b) probability is 3/5 because the total no. of areas are 5 and in N4 system out of 5 navigation error three are less than 10nm.
