The project managers multi-attribute utility function is: u(x1,x2)=0,8u(x1)+0,6u(x2)-0,4u(x1)u(x2). Please use the multi-attribute utility function to determine the utilities of the different outcomes in the decision tree. Please find utility of a project which overruns by 2 weeks and costs 70 000 PLN we proceed as follows. From the single-attribute functions we know that: u(2 weeks overrun)=0.6 and u(70000 PLN cost)=0.86. Therefore: u(2 weeks overrun, 70000 PLN cost)=
