Orders, BOM items, operations, work places and their capacities are the central elements of residue-free scheduling in the control centre.
The ams.leitstand consists of the above interactive planning table:
1. Jobs table, BOM items and operations
All shared jobs are initially read into the planning, the selection rules in the control centre are configurable. Orders can be loaded regardless of ams.erp. Tabular orders, BOM items, operations can be invoked. The information displayed via XML is freely designable. To find similar jobs to findyou can use the search function. As a full-text or detailed search, the search result is highlighted.
2. Timeline and history
The planning board is set up as a bar chart, where the time axis is horizontal and the sequence of jobs is displayed vertically. In each line, the assignment of a job with all of its operations is represented by colored bars. A scaling of the time axis can be easily and continuously adjustable at the push buttons.
3. Work places
The vertical jobs are displayed in a hierarchy in the form of resource types or groups in a tree structure. Substructures can be shown and hide as needed. Per workstation you can set in the ams.leitstand whether the termination at all, should be done with infinite capacity or with real capacity. About the level of performance, the availability and productivity in the planning is incorporated. Residence or cycle time allows fine adjustment of planning data without adjustments to the work plans you have to make in ams.erp.
4. Available capacity
The available capacity range is determined from the shift model in ams.erp from the work places and is represented by the planning board:
5. Pass of an order with BOM items and operations
If an order is selected in the table, you can see in the bar chart by the representation of the timing of all of its operations at a glance. All operations of the selected job will be surrounded by black borders, all other operations can also be hidden. The left red line in the planning board represents the current time, it pushes every minute right ahead. Since the planning is done without leaving a residue, operations not started automatically were pushed ahead; launched operations are starting "nibbled" from the default time accordingly. Only when operations were reported as completed, they disappear from the planning board and the freed capacity can be re-occupied.
6. Punctuality and delay traffic light visualization
Complaints from customers due to late deliveries can be avoided if we recognize them early and react appropriately. This helps the delay visualization in the form of a user-defined traffic light principle for the deviations from the confirmed delivery date. Late operations are highlighted and presented the schedule variances in calendar days. For planners, this means that the most critical jobs can be found at the top and must be handled accordingly.
7. Detailed planning and visualizing the impact of rescheduling
Planning algorithms that enable automatic optimization of logistic objectives as well as the manual rescheduling with immediate analysis of the impact on all orders. In the last case, for example, Operations are pushed horizontally along the time axis as well as to another work place. In order to recognize resulting impact of rescheduling made in the control centre immediately, these are with red (down by x days) and green (improvement by x days) arrows marked. So is immediately apparent which jobs are as hard hit when re-planning or what-if simulations. Throughout the planning, the dependencies of the job networks and structures should be considered and applied. Dynamic or static bottlenecks are visualized on the time intervals of operations.
Further planning and optimization functions:
With the help of the UnDo function the last rescheduling in the control centre can be made undone. The function is directly from the console menu at any time easily accessible.
Manually fixing and frozen zone
Are jobs already scheduled and should never rescheduled under no circumstances (eg if a customer already shifted delivery date has been communicated), these can be disabled via the freeze function. Furthermore, a solid frozen zone can be configured in the planning board.
Simulation of different capacity scenarios
Often the question arises whether it is useful to have an additional shift that important jobs can be delivered on time. In ams.leitstand such situations can be simulated directly on request. For this, the shift patterns and model during the planning session can be overridden. The newly created capacity offer is shown in the planning board immediately and can be considered in the manual and automated planning. Thus, effects are visible on all orders.
The availability of materials
The availability of materials or intermediates, are taken from ams.erp and scheduled as the earliest start date. By writing back the planned start / end dates from the production planning to ams the loop is completly closed.
The initial scheduling is done in ams.leitstand either forward (as-soon-as-possible) or reverse (just-in-time). In the planning board, however, the termination per job can be changed: you can, among other things, fast start with a pre-production and then put the parts into stock and then just-in-time schedule the final assembly.
Virtual machine groups and alternative jobs
Work places can be assigned to multiple skills. This allows planning alternative machines or virtual machines groups are mapped, without having to make changes to work plans.
Operation and daily comments
About comments you can place important informations directly to the operations. These can be, for example, special features are noted and filed apparent, even for colleagues. Comments are quickly and intuitively accessible via the context menu in the process. If a comment has been saved to a task, you can see it with a littel icon on the job.
If you move the mouse, for example, on an operation, relevant information is displayed. This representation can be configured via XML due to the customers requirements.
