Shop calendar subsystem

Reliability of Planning

Dates scheduled planning and production over your manufacturing horizon.
The MFG Shop Calendar subsystem eliminates problems by making it easy to define and specify an accurate shop work calendar. It relieves your scheduling headaches by giving you accurate lead time forecasting and realistic start dates. With this subsystem, you define your own calendar of working days. You can work with a planning horizon of three years or more, and you choose the time aggregates you prefer for collecting information and for producing a wide range of reports.

The Shop Calendar gives real control over your production timing.

Managing the timing of events in a manufacturing environment depends on knowledge of the shop's working days. For many companies, problems occur because production schedules were made without skipping non-working weekends, holidays, and vacations. The Shop Calendar subsystem eliminates these problems by making it easy to define and specify an accurate shop work calendar. This relieves you of scheduling headaches through accurate lead time forecasting, and realistic start dates.

User defined and maintained calendars.
You define your own calendar of shop days so that scheduling will always be accurate. If a calendar needs to be adjusted, adding or deleting working days only takes minutes. The system will then readjust schedules automatically.

User defined time aggregates.
It is often useful to aggregate information by time periods such as weeks, months, and quarters. With the Shop Calendar subsystem, it is easy to define the relationship between different periods of time. These time periods can be used extensively by other systems, such as the Master Scheduling and MRP subsystems. In addition, they are also used to generate useful reports. For example, a Purchase Order Commitment report could be viewed by month or quarter, based on the time aggregates specified in the Shop Calendar.

Planning horizons.
It is important to define a shop calendar far enough into the future to cover long-term production requirements. The Shop Calendar subsystem supports a three-year shop calendar, allowing a planning horizon of up to two years. This horizon can be extended even further if necessary.

Automatic data calculations.
Several calculations can be performed quickly and automatically by this subsystem. To determine the start date of a work order, for example, the subsystem uses the work order's due date and time. Since the lead time is expressed in terms of working shop days, the subsystem takes into account non-working weekends and holidays. The Shop Calendar subsystem calculates the start date of each manufacturing week within each fiscal year, and can also identify the day of the week of any given date. Because it distinguishes between working and non-working days, the subsystem helps avoid inadvertent scheduling of production during plant shutdowns and holidays.

Reports printed by Shop Calendar subsystem include:

  • Weekly Shop Calendar
  • Daily Shop Calendar
  • User-maintained Shop Calendar Data.

Full integration with other subsystems.
For easier updating, shop calendar maintenance is performed as a separate function. However, once updates are made, these are automatically reflected in related planning and scheduling functions. This is possible through unique shop day numbers which the system automatically defines.
