material transfer systems goldratt's theory of constraints -

This applies to his logistics system and another reference is described as "crossing the continent of the conveyor belt", but the continuous flow in his plant achieves the same purpose at the manufacturing level.This, as well as the relatively low inventory in the chemical process industry, suggests that by looking for ways to eliminate changes in processing and material transfer time, it is likely to go beyond the theory of constraints.

No manufacturing process can work faster than the slowest operation, constraint, or capabilityRestrict resources.This goes on to project management where none of the projects can be completed faster than the events on the critical path.The impact of manufacturing includes longer cycle times and more inventory, both of which make it more difficult to meet customer needs.

Constraints or capacity-Constraint resources (CCR) limit the throughput of the manufacturing process, just as the critical path defines the shortest time for project completion.
Changes in processing and material transfer time reduce throughput because the time lost under constraints can never be recovered. Favorable changes do not offset adverse changes.
