An initial solution has been given to the following workcenter layout problem. Each location is 180 feet long and 90 feet wide as shown on the following figure. Use the centers of departments for distances and measure distance using metropolitan- rectilinear distance. DEPARTMENT A B C D 0 15 30 60 B 0 15 10 DEPARTMENT 020 D 0 180' 180' 180 90' | A | B C 90' | D |90 Given the flows described and a cost of $4 per unit per foot, compute the total cost for the layout?
