An initial solution has been given to the following process layout problem. Each department is 40m long and 20m wide as shown in the figure below. The distance to move horizontally from one department to the next (center to center) is 40m, and the vertical distance between departments (center to center) is 20m. Initial Layout: 40 m D Flow Matrix (Daily) Department A 30 20 B 15 10 D 15 20m 1 A B D Departmen Olo 20 25 Using the flows given above and rectilinear distances as a measurement of costs, which of these four layouts is best to minimize transportation costs? D B Ob) D B. A c) B D Od) B A D
