An architect plans to build a house, and he has 3 plots of land to build it on, plot A, plot B and plot C. The architect is concerned with 2 aspects of these plots, the location and the type of soil. The architect thinks that the type of soil is 2 times more important than the location, he also thinks that the soil of plot A is 2 times better than that of B, that of B 2 times better than that of C, and that of A 3.5 times better than that of C. The architect thinks that the location of plot C is 2 times better than that of B, that of B is 3 times better than that of A, and that of C is 6 times better than that of A. Using analytic hierarchy processes to determine the tables that express the preferences of the architect.
