INTRANAV VIRTUAL Manufacturing Solution
Virtual Process Solution
Digital Twin controls industrial manufacturing complexity: automating manual manufacturing steps with production line virtualization from INTRANAV.
With an ever-increasing range of model variants to be produced, the question arises as to how the high complexity of production, especially in variant production, can be monitored, time-consuming and error-prone scanning processes dispensed with, and all quality standards continuously maintained. The key to success is the combination of process virtualization with real-time indoor track & trace data and digitized workflows that automate previous manual processes in manufacturing to a high degree. For production to flow smoothly, pre-assembly and main assembly must be synchronized, otherwise specified order time windows cannot be met and production delays occur. Plausibility checks prior to main assembly must be reliable and automatic, as incorrect assembly can lead to considerable time and cost expenditures as well as safety risks. INTRANAV provides valuable real-time location data for process optimization and automation to optimize your production processes as well as material supply and flow. With INTRANAV, documentation and traceability of your processes is available at the push of a button via reports. With the new automated processes and workflows through highly accurate real-time location data, you are able to avoid bottlenecks, shortages, errors and significantly reduce search times.

INTRANAV VIRTUAL Manufacturing Solution:
Real-time data-driven process automation
This is how VIRTUAL Manufacturing works with INTRANAV!
Order Matching with RTLS – Generation of the Digital Twin
Before a single component runs through the assembly, an order matching (systemic marrying) of the INTRANAV.RTLS TAG with the component in the SAP system must take place, so that the material flow can be tracked during the entire production process and automation processes can be triggered to the correct component. With the INTRANAV.APP “Order Matching”, an initial scan step in the Start Zone/Paring Zone systemically marries the corresponding production order (FAUF) with the TAG located on the rack. In addition, further manufacturing accompanying documents can be stored virtually in the system, enabling digital, paperless handling throughout the entire manufacturing process. This ensures process reliability throughout the entire assembly process, thus eliminating the possibility of production information being lost or accidentally mixed up.
Real-time location along the production line
By equipping INTRANAV.RTLS on the production line, the workers receive (±) 10 cm accurate real-time location information of all assembly steps as well as of the boxes, containers, load carriers and racks located on the assembly line, which are manually moved from cycle to cycle. This real-time information is digitized in INTRANAV.IO and sent to the SAP PP (Production Planning and Control) system via an interface. The entire production flow is completely transparent and can be tracked in real time as a Digital Twin.
Workers can thus see in real time: which components and which material are in the respective cycle, where material replenishment may be required, whether the production steps are running synchronously or whether there are time deviations, or even to what extent delays are to be expected in individual sections.
In the event of KPI deviations, production managers are notified immediately by alerts so that they can initiate appropriate intervention measures.
Automatic (scan-free) cycle feedback on the production line: INTRANAV transmits real-time data to SAP ERP
INTRANAV controls the production line by automatic feedback after each started and completed production cycle. The tracked racks on which the production pieces are located are manually pushed from cycle to cycle, each time passing through a virtual zone, whereby the cycle sequence is automatically posted as “completed” in SAP PP, so that the next cycle is informed in real-time about the status and can start with the next step. Automatic cycle feedback ensures quality standards and eliminates manual scanning within the line. Booking errors are thus eliminated so that no process step is omitted. This saves time for the workers, as manual scanning is no longer necessary. Late or early posting due to manual scanning can have critical consequences for the production line, such as excess material at the tightly scheduled storage/assembly area or idle time, which in turn leads to inefficiencies in the entire supply chain process flow. With the link to SAP PP (Production Planning and Control) and SAP EWM (Extended Warehouse Management), information can be provided at higher levels, triggering follow-up order and information processes.
Elimination of scanning and booking steps
By means of virtual zones, which are individually defined for each cycle via the INTRANAV.IO platform, manual scanning and booking processes are replaced by auto-bookings (auto-ID). The information is transferred to the SAP PP system via the interface. Time-consuming manual processes carried out by workers, such as scanning the barcode of the machine card in order to book operations or material, are automated on a cycle-by-cycle basis with INTRANAV. This reduces incorrect bookings and speeds up the production process, as the workers can now spend more time on value-added work.
INTRANAV Auto-ID alone enables automatic material postings, cycle-related operation postings, plausibility checks.
Sequence monitoring: Automatic (scanner-less) plausibility check of the components
The real-time location data is collected within the production line using INTRANAV.RTLS TAGs, which are installed on the assembly carts. These each contain corresponding ID group addresses to tell the system which TAG is responsible for which assembly area. Thus, for the assembly trolleys (racks) of “Product A”, there is a separate numerical group for the pre-assembly of the “engine”, for example, as well as for the assembly trolleys in the main assembly line. Analogously, this also applies to production line B. Thus, each INTRANAV.RTLS TAG has its own, area-internal address. This means that the assembly units are digitally networked and can track the production orders paperlessly in all assembly branches.
With the INTRANAV.APP “Assembly Check” the final plausibility check takes place whether the components may be assembled with each other. In two geofences, it is checked whether the individual component fits to the corresponding assembly before it goes on to the main assembly. This involves a systemic comparison in SAP. A monitor shows whether the components fit together or not.
This important component check ensures that only matching components and groups are assembled together. This avoids particularly time-consuming and costly rework, and ensures the ongoing quality and correctness of the processing of all further production steps. Process assembly errors are avoided.
The basis for the plausibility of pre-assembly and main assembly synchronism of cycles, cycle-related picking (large components), generation of transport orders, cycle-related option display are implemented by INTRANAV.
Automatic (scanner-less) order transfer when changing the rack
At a defined point in the assembly process, a rack change must be carried out for production-specific reasons. An event trigger triggers the release for the rack change via two geofences. The components are transported from one rack to a new rack. Since the racks are equipped with the INTRANAV.RTLS TAGs, an automatic transfer of the information of the FAUF from the old rack to the new rack must also take place here. The INTRANAV.APP “Rack Change” ensures the automatic transfer of the FAUF from the old to the new rack. No scanning process is necessary. The TAG of the old rack is automatically reset so that new information can be written to it. The INTRANAV.APP “Rack Change” displays “Rack change confirmed” via a monitor as soon as this process has been successfully completed.
This process step ensures seamless transition of information transfer and secures further production tracking. Manual, erroneous and time-consuming scan-based handling is no longer necessary, and the dangers that arise from paper accompanying slips, such as the risk of confusion or loss, are completely eliminated with INTRANAV.
Cycle-related automation triggers
INTRANAV.IO can be used to set up additional geofences and triggers to call up production order-related information (options), as well as to start additional setup processes for fixtures, e.g. by means of a programmable logic controller (PLC).
This includes for example:
– Checklist call at Q-gates
– Option display of worker information
