Real time location and asset tracking
Automotive manufacturers seem to be at the forefront of implementing Industry 4.0 and 'Industrial Internet of Things’-initiatives. The aim is to track and measure goods throughout the whole manufacturing process, from goods inwards to final dispatch (read more about asset tracking RFID software). This makes the complete production process more visible, efficient, and ultimately more profitable. In many manufacturing plants, the development of making the workflow more visible is already implemented or in progress.

There are, however, some areas in the process, where assets, materials and even finished vehicles are not visible in the digital world. This applies especially to the production process of vehicles, where assets do not follow a predetermined path. For example, once a vehicle leaves the manufacturing line and enters the finishing area, it can be moved freely around the production site. The challenge is to know the location of each vehicle at any given time and subsequently avoid production delays. To meet these challenges, Real Time Locating Systems can help you make unguided processes highly visible and integrate them into the digital landscape. The system enables your company to monitor, track, and localise assets more effectively, such as vehicles, and helps improve processes your organisation is currently struggling with.
