apintra® Production Control (ERP/PPS)

What are your expectations towards an ideal production planning and control system (PPS)? You need it to be flexible and react to changing production processes quickly. It must be versatile, offer easy correction options, and provide extensive information. Together with the apintra parts list processor with variant logic, the apintra production control and critical path analysis system combine all of these features – among many others.

Unique features: With the apintra production planning and control system, you can establish multi-level parts lists and divide them into key division and production sector. Some more distinctive features are our multiple variant systems and the use of formulae.

Total flexibility: Countless issues can force you to adapt your production process, as for example changes in demand, new variants, or a customer’s particular wishes. With the help of the critical path analysis method that is part of the apintra PPS, your production control system is ready to adapt to changes at any time. Easy correction options and a high variability make it even easier for you, and you can retrieve detailed information whenever you need it.

Carefully constructed additional features: You can tailor our PPS to your individual needs and choose from a variety of additional features, such as variant logic. The modules BDE, PZE, or MDE allow you to log your employees’ work time, operational or machine data. All modules are equipped with the necessary interfaces for further data processing in payroll accounting programs.

Recursive parts list processor: apintra® software includes a recursive feature to display parts list trees. The user can “travel” along the tree and edit specific positions along the way.

Duplicate variant: apintra offers two variant logics that run independently from each other. The duplicate is generated from a copied parts list, which is then adapted and modified accordingly.

Formulae variant: A recursive tree provides the possibility to store formulae for “quantity,” “length,” and “width.” These can be transformed to absolute values when the parts list is being processed.

The following list shows some selected features of apintra production control:

Integrated Critical Path Method

Critical path methods are all techniques used for the analysis, description, planning, steering, and controlling of processes. They are based on graph theory, as well as the time and resources used.

The critical path method that is integrated into apintra software does not make use of the commonly used NetChange procedure because it is just not precise enough for us. We want our system to react to changes in an optimal way, which is why we always recalculate the entire critical path.

We take the efficiency of materials and capacities into account to optimize our calculation system and refine its validity.

Depending on the requirements, the calculation process begins either with the starting procedures, based on which the earliest possible start date for subsequent processes are defined (forward planning) or with the last procedures (that do not have any successors) to define the latest possible finishing dates of each preceding process (backward planning). A combination of the two methods is based on the predefined start and end dates and allows for four additional features for every process:

  • Earliest start-time (from forward planning)
  • Earliest end-time (from forward planning and respective durations)
  • Latest end-time (from backward planning)
  • Latest start-time (from backward planning and respective durations)

Buffer Time:
Buffer time is the temporal leeway for the execution of a process and is also called time reserves. This leeway can be used by shifting the process and/or by extending the duration of a process.

Integrated BDE/PZE/MDE

The modules operational data logging, staff work time logging, and machine data logging provide all the tools you need to collect operational and work time data. Time recording is enabled on additional electronic devices, which are processed on the basis of the on-file work time models. Interfaces to your payroll accounting programs are, of course, also available. You can also define different work time models and functions for flextime and piecework accounting.

There are multiple tools to identify individual employees, depending on which type of recording you use: RFID, barcode, and chip cards. You may also add an optional access control extension.
The BDE module logs all of your company’s operational data. Times that belong to a specific production order are assigned to their initiator, including times used and “actual” costs. Reasons for disturbances, disruptions, and quantities are also logged. Evaluations can be based on production orders and capacity points. A capacity point’s efficiency is optimized automatically, and its data is processed in the critical path analysis. You can view work progress, order status, and all order-based performance at any time.

There is also an optional, fully automated MDE (machine data logging) tool you can add. Furthermore, our BDE/MDE modules can easily be paired with a graphic control station.
