Part 2 Problem 1: Trade-Off Analysis (20 points) As System engineer, you have asked to help in the selection of a power generator a company plans to ra buy for power backup (in case of power outage), and you decide to apply the Trade-off method to help make the decision about which option to buy. There are 4 options to consider and their specifications (attributes) are provided in the table 1 below: Table 1: Raw Attribute Scores Power Power Fuel Consumption CO2 emissions Price Generator (KW) (l/h) Kg CO2/h ($) Option 1 180 475 56000 Option 2 505 65000 Option 3 462 52000 Option 4 690 205 495 67000 650 200 675 635 165 Note: Report Scores/Results with two decimal places. The weights of the attributes are provided below in Table 2: Table 2: Attributes weights Attributes Weights Power 0.30 Fuel Consumption 0.25 CO2 Emissions 0.15 Price 0.30 1. Use the linear Value function and calculate the Options values based on the raw attributes provided in Table 1.
