PPC Sequencer for detailed planning
The basis for efficient and transparent production is a detailed and feasible production plan. In detailed planning, which is normally used in the short-term horizon, the relevant target variables are as follows:
- Just-in-time manufacturing
- Cost saving by optimising the order sequences for minimum setup or by creating campaigns
- Optimum workload on the resources
Detailed planning encompasses the aspects of the optimal sequencing of operations or orders and the detailed production capacity levelling within a short-term horizon.
The PPC Sequencer supports the day-to-day work of the planner:
- in the search of a gap for an operation/order on permitted resources (with graphical and tabular scheduling board)
- in the scheduling and rescheduling of operation/order sequences for setup optimisation
- in the summary of similar products for a joint production (creation of campaigns)
- in the rescheduling of operations, e.g. due to machine failures or staff shortages
Benefits
- Consideration of dependent operations/orders (multi-level possible as well)
- Setup optimisation: Calculation of dynamic setup transitions (dependent on the sequence) using a setup matrix
- No violation of the requirement dates considering the complete, multi-level production network
- Combination of automatic and manual planning
- Numerous planning strategies with flexible parameters that can be combined to represent the following scenarios:
- Minimised setup times with the additional consideration of due dates
Detailed planning overview: graphical planning board
Detailed planning can be carried out completely in the background or online using the corresponding function code in the PPC Sequencer.
Manual planning is possible as well. In this case, the responsible is assisted by the tool for an optimal realization of his or her decisions:
- Drag-and-drop
- Overview of all gaps, graphical and tabular
- Display of setup times for available alternatives
- Simulation possibilities
- Indicators, such as the range of coverage or buffer to the due date
An advantage of the PPC Sequencer is the combination of automatic and manual detailed planning. The automatic scheduling offers a proposal for the planning allocation with all its consequences (derived indicators, exceptions). Afterwards, it is possible to fine-tune the results manually.
