How to use fixed batch times
Change overs schedule
This example shows the routine of a set-up operator in charge of changeovers of 3 presses. After the change over on the press 1, he/she goes to the press 2 in order to realize the change over, then does the same on the press 3. At the end of the cycle, he/she comes back to the press 1, the batch has just ended and he/she can do the next change over.
This method is used to optimize the number of set-up operators working on multiple production lines. If the batch time of one production line is equal to the sum of the changeover times of all the other lines you will be able to have your set-up operators switch smoothly from one line to another in order to proceed to their changeovers.
In the real life, you need to include a safety time in order to secure this process.
For all equipments managed by the same set-up team:
Batch time of an equipment > sum of change overs of all other equipments
