Question

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 2 Room Room 4 Room 5 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. Jrom Ty Materials Welding Drills Lathes Grinders Benders 20 0 20 40 60 Materials 1000 55 20 40 20 40 Welding 25 60 40 20 Drills 20 55 20 40 Lathes 20 20 120 Grinders 55 Benders 15 25 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 highest number of moves between each other. Based on the flows shown in the matrix, it is likely that the processes Materials and Welding 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 2 Materials Room 3 Welding Room 4 Drills Room 5 Grinders Room 6-Lathes The cumulative distance based on the overal movement of material between processes for this layout feet (enter your response as a whole number.

Explanation / Answer

We need to reorganise the tables as per the new layout as below

Cumulative distance = Sumproduct of the above two tables = 11800 feet
