Question

Hello,

Need to see the solution. How they got these numbers.

Roy Creasey Enterprises, a machine shop, is planning to move to a new larger location. The new building will be 60 feet long by 40 feet wide. Creasey envisions the building as having six distinct production areas, roughly equal in size. He feels strongly about safety and intends to have marked pathways throughout the building to facilitate the movement of people and materials. See the following building schematic Room 1 Room 4 Room 2 Room 5 Room 3 Room 6 His foreman has completed a month-long study of the number of loads of material that have moved from one process to another in the current building. This information is contained in the flow matrix on the left below. Finally, Creasey also developed a matrix to indicate distances between the work areas shown in the building schematic, shown on the right below. 1 2 20 From TQMaterials Welding Drills Lathes Grinders Benders Materials 0 100 55 0 0 55 Welding 25 0 0 45 0 0 Drills 25 0 0 0 50 0 Lathes 0 30 0 20 0 Grinders 55 0 70 0 0 Benders 5 0 15 0 0 1 2 3 4 5 6 3 4 5 6 40 20 40 60 20 40 20 40 60 40 20 20 40 20 Based on the flows shown in the matrix, it is likely that the processes Material and Welding are in rooms next to each other as they have the highest number of moves between each other. Based on the flows shown in the matrix, it is likely that the processes Drills and Grinders are in rooms next to each other as they have the second highest number of moves between each other. One of the layouts that could be designed is: Room 1 = Benders Room 4 = Drills Room 2 = Materials Room 5 = Grinders Room 3 = Welding Room 6 = Lathes The cumulative distance based on the overall movement of material between processes for this layout = 12,600 feet (enter your response as a whole number).

Answer 1

Based on the flows shown in the matrix, it is likely that the processes Material and Welding are in rooms next to each other as they have the highest number of moves between each other.

(Moves between Material and Welding = 100+25 = 125)

.

Based on the flows shown in the matrix, it is likely that the processes Drills and Grinders are in rooms next to each other as they have the second highest number of moves between each other.

(Moves between Drills and Grinders = 50+70 = 120)

.

The cumulative distance baased on the overall movement of material between processes for this layout

= Movement between Benders and Materials x Distance between Benders and Materials

+ Movement between Benders and Welding x Distance between Benders and Welding

+ Movement between Benders and Drills x Distance between Benders and Drills

+ Movement between Benders and Grinders x Distance between Benders and Grinders

+ Movement between Benders and Lathes x Distance between Benders and Lathes

+ Movement between Materials and Welding x Distance between Materials and Welding

+ Movement between Materials and Drills x Distance between Materials and Drills

+ Movement between Materials and Grinders x Distance between Materials and Grinders

+ Movement between Materials and Lathes x Distance between Materials and Lathes

+ Movement between Welding and Drills x Distance between Welding and Drills

+ Movement between Welding and Grinders x Distance between Welding and Grinders

+ Movement between Welding and Lathes x Distance between Welding and Lathes

+ Movement between Drills and Grinders x Distance between Drills and Grinders

+ Movement between Drills and Lathes x Distance between Drills and Lathes

+ Movement between Grinders and Lathes x Distance between Grinders and Lathes

= (55+5)*20 + (0+0)*40 + (15+0)*20 + (0+0)*40 +(0+0)*60 + (100+25)*20 + (55+25)*40 + (0+55)*20 + (0+0)*40 + (0+0)60 + (0+0)*40 + (45+30)*20 + (50+70)*20 + (0+0)*40 + (20+0)*20

= 12,600 feet
