Activity Relationship Chart (REL Chart)
Activity Relationship Chart
Facility-layout tool rating how important it is for pairs of departments or functions to be located near each other.
Examples
- 01When planning a new plant, the industrial engineer uses an Activity Relationship Chart to rate that welding and painting must be close, while welding and the canteen must not be.
- 02The project team validates the REL Chart ratings in a workshop with logistics, quality and maintenance before drawing the first layout.
- 03Comparing two layouts against the Activity Relationship Chart shows that option B places all 'absolutely necessary' pairs next to each other.
