In order to counter the growing complexity of modern products in vehicle, machine or plant construction, these products are increasingly broken down into subsystems or modules. The virtual development of the overall system (including modeling, simulation and optimization) is currently typically carried out by one person in a solitary work process. This leads among other things to the following problems: Since common software products do not allow synchronous collaboration, the complex and error-prone task of modeling is a burden for individuals and can lead to inefficient communication and redundant workflows. The simulation of the overall model usually also only takes place at one location, which inevitably leads to confidentiality problems when models are passed on between the companies involved. In addition, data exchange is usually not standardized and is often solved ad hoc and inefficiently. The motivation of DisMoSim is derived from this: The decentralized reality of today's development processes from modeling to simulation to optimization and verification of cyber-physical systems is to be mapped in this project and supported with new tools.

The goal is the design, prototypical implementation and evaluation of new digital tools and algorithms to support collaborative development at different locations. In the area of ​​3D modeling, new operating and visualization concepts support more effective and efficient teamwork in and between companies. Multi-touch and pen-based inputs on large displays or mobile devices allow seamless group work at the same location ("co-located") or in distributed teams ("remote"). Know-how protection in model and data exchange between OEM and supplier is ensured by new algorithms for coupled simulation of the subsystems. The adaptation of standardized web technologies guarantees a uniform and efficient data transfer. The achievement of all these goals is underpinned by a concrete test scenario. The distributed modeling, simulation, control and optimization is demonstrated on an entire vehicle.

DisMoSim creates an infrastructure that enables the Upper Austria University of Applied Sciences to support Austrian industrial partners in subsequent projects to implement the “Industry 4.0” vision, particularly in the areas of vehicle, machine and plant engineering. The findings will be incorporated into existing and new cross-faculty courses on the topic of “Modeling and simulation of cyber-physical systems”.


The project is funded in the COIN Cooperation & Innovation program by the Federal Ministry of Economics, Family and Youth and the Federal Ministry of Transport, Innovation and Technology with a budget of EUR 392,472.
