Multi-column Process Chart
Let us consider five different parts (#1, #2, #3, #4, #5) which travel from R (receiving) to S(Shipping) departments by following different routes. Between receiving and shipping, there are machines located at A, B, C, D, E and F. Our job is to find a layout which will reduce the travel time and increase the efficiency. We can make improvements by rearranging the flow.
|
Part Number |
Route |
|
1 |
R A B D C F S |
|
2 |
R B D C A S |
|
3 |
R E F B A C D S |
|
4 |
R F A C D S |
|
5 |
R C A D S |

Let us rearrange the layout. In the previous layout R-F; A-S; B-F; R-E were the routes that produced high number of steps, thus causing longer travel distances. We are going to rearrange the layout and make R-F; A-S; B-F; R-E routes shorter. Since we had C-D and A-C repeated four times we are going to keep C-D and A-C as close as possible. Our new layout is given below:
