Methods, devices and systems for splitting an integrated manufacturing and distribution plan for use by separate manufacturing and distribution execution systems
A consolidated plan splitting methodology sends distribution orders to a distribution execution system and planned production to a manufacturing execution system. Instructions from the planning system involving only movements of inventory within the distribution s system (e.g., warehouse to warehouse transfers) are passed directly to the distribution execution system. Instructions from the planning system involving movements of inventory where either the source or destination is in the manufacturing system causes a splitter located between the planning system and the distribution and manufacturing execution systems to carry out a decisional process wherein the movement of inventory is broken down into a selected number of distinct intermediate legs. Control of inventory balances is passed between the distribution and manufacturing execution systems as appropriate as the inventory moves from one execution system to another.
