action Engineering & Management Department 9.4. Judy Grim is looking for a new computer system for her small business. She has determined that the most important overall factors are hardware, software, and vendor support. Furthermore, Judy has narrowed down her alteratives to three possible computer systems. She has labeled these SYSTEM-1, SYSTEM-2, and SYSTEM-3. Judy decided to use the analytical hierarchy process (AHP) to carry out the selection. In carrying out the AHP process, Judy needs to determine the factor weights of the three systems over software. In comparing the three systems, Judy determined that system-1 is very extremely to strongly preferred over system-2. At the same time, system-lis strongly to very strongly preferred over system-3. In comparing system-2 to system-3, Judy decided that system-3 is more important. System-3 is moderately to strongly preferred to system-2. With the given pairwise comparisons: - (5 marks) Construct a pairwise comparison matrix and then compute the factors for system-1. system-2. and system-3 over software. b. You have your doubts as a decision maker that Judy was not consistent in comparing between the three systems. Hence, compute the consistency ratio to make sure that her responses are consistent. To compute the consistency ratio, you have to go through the whole process, that is weighted sum vector, consistency vector, consistency index, lambda and the consistency ratio. Notes:- 1.
