Order control and feedback are used to identify and correct production both short- and long-term problems that arise in the PAC system.
The process can be started when the following prerequisites are met:
There are several tools in M3 that can be used to identify and correct production problems.
The following section describes the activities in this process.
Identify and Prioritize production problems
This activity involves identifying problems and putting them in order of priority. The priority can be based on many factors, such as urgency, the orders’ effect on costs, or whether they are customer or internal orders.
In any PAC system, the following basic problems can occur:
The following tools can help to identify problems regardless of reason.
For more details, refer to the following documents
Correcting the identified problems requires prioritization for short-term resolution. This evaluation includes determining what the alternatives are and whether they are sufficient.
The actions to be taken should first be possible within the production limits. If not, planning changes (such as new need date, delete order, reducing load or order quantity) may be necessary.
The following short-term solutions can be used for either problem type.
Higher-level planning changes can include changing the need date, deleting the order, reducing expected load, or reducing order quantities.
As an example, a short-term solution can be to implement an extra shift (overtime) for a week to improve the immediate situation.
Each problem requiring a long-term solution must be evaluated to determine why this problem occurred and how it is possible to prevent it from recurring. Long-term solutions often require closer cooperation and planning in the various affected functions.
Feedback of information to the planning system is necessary to fully inform personnel of the current production status. For further details, see Monitoring Production.
As an example, if a problem recurs several times, it may require a more long-term solution such as purchasing more machines to increase capacity. This kind of solution cannot usually be implemented immediately, but requires considerable review before anything can be done.
