A mobile robot is serving two cells located at either sides of the AGV (Automated Guided Vehicle) track, as shown by the figure below. There are three machines placed in each cell. Given the from-to chart in the table below, we want to find the best machine arrangements for both cells. Rearrangement is limited only to machines within each cell. Assume that P/D point (pick up/drop off) of each machine is located at the midpoint of the machine edge along the AGV track. The length of departments B and E are twice as other departments.

1) How many layout combinations are possible to propose?

2) In your flow-between chart, what is the flow between A and D? 70

3) In your flow-between chart, what is the flow between B and E? 85

4) What is the distance score of ABC-EFD layout alternative?

5) What is the distance score of ACB-FED layout alternative?

6) What is the distance score of BAC-EDF layout alternative?

7) After exhausting all the layout combinations and calculating their distance scores, what is the best layout? (follow my logic of stating layouts in questions above)

8) What is the distance score of the best layout?
