John, who works at Swatch, has decided to use the weighted attribute method to compare three systems for manufacturing a watchband. The vice president and he assistant VP have evaluated each of three attributes in terms of importance to them, and John has placed an evaluation from $0$ to $100$ on each alternative for the three attributes. John's ratings for each alternative are as follows:

$\backslash$table$[[$Importance Score,Vp$,$AssistantVP,Attribute,Alternative$],[\backslash$table$[[$Economic return $>$ MARR$],[$High throughput$],[$Low scrap rate$]],\backslash$table$[[20],[80],[100]],100,1,2,3],[$Economic return $>$ MARR,$50,70,100],[20,$High throughput,$100,60,30],[,$Low scrap rate,,$40,50]]$

a$)$ Use the weights above $($in the table$)$ to evaluate the alternatives.

b$)$ Are the results the same for both persons' weights? Why?
