Since to calculate weighted sum analysis we need to have ratings for how well that option satisfies particular criterion so we will take ratings as: outstanding 10 very good 9 good 7 adequate 5 marginal 3 poor 1 none 0 “ratings taken from Bary Boehm’s software engineering economics ,chapter 15 page 235 fig 15-2” For weighted sum approach sum of weights has to be 100 so we will take weights 15 for energy savings and safety ,5 for accountings and savings analysis and 10 for rest thus total weight is 6*10 + 2*15 + 2* 5= 100 criterion Energy inc weighted rating Micro con weighted ratings Econetics ratings Steady state energy savings 10*15=150 8*15=120 12*15=180 Controls 5*10=50 9*10=90 3*10=30 Ease of Operations 5*10=50 7*10=70 5*10=50 Diagnostics 5*10=50 7*10=70 1*10=10 Availability 0.990*10=9.9 0.995*10=9.95 0.975*10=9.75 Growth/update Capability 5*10=50 7*10=70 5*10=50 Safety features 9*15=135 7*15=105 5*15=75 Accounting system 7*5=35 7*5=35 9*5=45 Vendor reliability 9*10=90 7*10=70 5*10=50 Saving analysis pkg 7*5=35 0*5=0 0*5=0 total 654.9 639.95 499.75
