PPC Production Control for Shop Floor
Therefore, a complete separation of planning and execution is not mandatory.
In general, features for planning and execution are strictly separated. In many scenarios, this is dictated by a separation of the responsibilities. But it can be useful to carry out both activities on the same or on a similar platform.
The module “PPC Production Control” is particularly attractive for customers who are concerned with the issue and looking for synergies between planning and execution solutions:
It is easier to find and edit the correct order to be confirmed with a tool that offers a transparent overview of the planning situation (e.g. the exact sequence of scheduled orders on a production line). This is particularly useful when planned values are also used for the confirmation, for instance in backflushing. If the planned figures accurately reflect the reality then actual activities can be equated with planned activities to spare the high costs of entering every deviation in detail.
- Implementation of time event and activity confirmations
- Booking of scrap and material consumption
- Visualisation of occurred confirmations
- Projection of the impact of confirmations on yet open, dispatched operations
During material staging:
The material staging can be regarded as the final step of planning. Despite a feasible sequence in the detailed planning with component availability checked on stock, shortfalls in the material supply to the production site can still occur during execution. Making such cases transparent and drawing consequences for planning (in this case the change of the order sequence) is vital for sustaining a production without unnecessary delays.
An important aspect is the easy handling of the module: the staging of a material is triggered from the planning representation (order sequence) through a simple click or with a few intuitive steps. The user benefits as well from easy accessible information about existing control loops that specify the supply location and type.
The material staging by kanban control according to the just-in-time/just-in-sequence principle is effectively performed with the PPC Production Control.
- Determination of component availability in production: production storage locations and bins, production supply areas (PSAs)
- Finding of control cycles for the replenishment of component stocks according to the kanban or JIT/JIS principle
- Initiation of stock transfer for the material staging in order to produce the planned operation sequences without undue delay
- Documentation of occurred material staging
During rescheduling in the short-term horizon:
- in tabular form with traffic lights
- in graphical form on the timeline with colour control for exceptions
Key figures are determined dynamically. For example, the range of available components for capital binding stocks in production is recalculated with a change of sequence. In the comparison of planned and actual data, the effects of plan variations for activities of the orders as yet to be performed are established.
Due to the increased transparency, exceptional situations are easily recognised and actions can be easily triggered (graphically or in tabular form):
- Rescheduling to other resources/machines, e.g. in case of machine failure
- Change of sequence to avoid set-up times
- Deallocation (undispatch) of operations with problems
- History and analysis of executed rescheduling
The following points can be clarified with the help of the PPC Production Control:
- Which orders are scheduled next on which production lines/work centres?
- What is the work progress of the orders and which confirmations have been booked?
- Are the orders up to now included in the production plan or have there been variations that influence further production (e.g. the orders already processed had excessive scrap or delays)?
- Has the material staging occurred yet
- If not: Which components must be transferred and how will they be provided?
- Are problems during the material staging expected (e.g. stock too low, components at wrong storage location)?
