Takt-Based Scheduling
Use
For it to be possible to switch to the change mode of the sequence schedule, all the orders in the planning horizon of the navigation tree must have the order quantity 1 and be takt-scheduled.
Using takt-based scheduling, you can split up all the orders with a lot size greater than one in the stipulated planning horizon into orders with the lot size one. In the process, each order is scheduled at a certain position in the shift. The number of positions in a shift, is calculated using the takt time and the time available. An individual position cannot be interrupted.
All orders that have not yet been transferred to production and all fixed and non-fixed orders for whichthere is no more free capacity in the planning horizon are planned infinitely. That is to say, they are scheduled at the first position beyond the planning horizon and all have the same start dates/times.
Features
You can execute takt-based scheduling interactively directly in the sequence schedule by choosing
Takt-Based Scheduling
.
The advantage of takt-based scheduling in the sequence schedule is that you can choose whether the orders that cannot be scheduled in the planning horizon are to be scheduled infinitely or deallocated.
Activities
Takt-based scheduling comprises the following steps:
Splitting of orders into lot size 1
The planned orders with a lot size greater than one are deleted and the system creates new ones with the lot size one.
Creation of an order sequence
The system attempts to arrange the orders in the sequence previously determined through the optimization process. In doing so, however, it takes into account the status of the activity (such as scheduled, released, conformed) and the time of scheduling, so that the sequence of the orders is liable to change again.
Takt-precise scheduling
Each order is scheduled in just one takt and receives an exact position as a result.
