A proposal has been submitted to replace a group of assembly workers, each working individually, with an assembly line. The following table gives the individual work elements. Element Te (min) Immediate predecessors 1 1.0 2 0.5 3 0.8 1,2 4 0.3 2 5 1.2 3 6 0.2 3,4 7 0.5 4 8 1.5 5,6,7 The demand rate for this job is 1600 units/week (assume 40 h/week) and the current number of operators required to meet this demand is eight using the individual manual workers. d) The initial cost to install the assembly line is $2,000,000. If the hourly rate for workers is $50.00/h, will the assembly line be justified using a 3-year service life? Assume 50 weeks/yr. Use a rate of return of 10%.
