Below is a list of the industry briefings offered at the CPS Summer School.
Buildings are responsible for 40% of energy consumption and 36% of EU CO2 emissions, proving that high energy performance of building infrastructures is key to achieving climate and energy objectives. Significant savings can be achieved using strategies such as user profiling based on data gathered using Internet of Things technologies to control equipment distributed in a building. For example, peak shaving strategies can yield savings in infrastructure required to provide peak power, and improved reliability of energy supply. In order to gain confidence in overall operation, it is necessary to integrate discipline-specific models (e.g., software, thermal, electrical). Building automation systems have a wide range of interconnected functions, including the management of energy consumption and maintenance of comfort through the control of heating ventilation and air conditioning (HVAC) in the internal environment. As buildings tend to become increasingly complex, through demands for sustainability and economy increase, model-based systems engineering approaches need to be in place to efficiently analyse the building Cyber-physical system. In this talk we are going to explore current building information systems model-based approached and present the advances of these methods through the INTO-CPS technology. Our purpose is to show how building cyber-physical systems can be re-designed and analysed through a multi-disciplinary toolchain of FMI-based co-simulation approach showcasing the INTO-CPS project outcome in the specific domain.

AGROINTELLI is a partner in the INTO-CPS project because we see the potential in the integrated tool chain to enable reduction of the development time. In addition, the cost of physical prototypes by modelling and co-simulation of all systems (electrical, software, hydraulic, mechanical, etc.) of the final intended physical product may be reduced, compared to current development practise. As time to marked is absolutely essential to us and a fundament for our competitiveness we see great potential in these tools.
AGROINTELLI will present how the modelling is done by integrating a series of simulation and modelling tools to create a tool chain, allowing for powerful analysis of the complete cyber physical system/prototype as part of our development of agricultural robots for the next generation arable farming.

Electric Vehicles are on the way to provide emission free private transport. One of the main drawbacks is the limited range of electric vehicles. The main goal of the automotive case study in INTO-CPS is to create a tool for range prediction of such vehicles. Thereby, the INTO-CPS toolchain supports the development of a route planning and monitoring assistant, as to find the optimal route and speed profile for a given route. Based on the prediction, we develop a controller which supports the driver in handling electric vehicles in a fast but energy efficient way and is able to react to unforeseen traffic or weather conditions.
TWT will present its experiences with setting up co-simulations based on the INTO-CPS framework. These simulations combine data obtained from the internet with detailed physical modelling of electric vehicles and FMUs created on the basis of a large number of tools. Finally, these simulations constitute the basis for testing the developed devices and concepts in a HiL setup and a driving simulator.

INTO-CPS is a H2020 R&D project that is developing a tool-chain and methods supporting continuous and discrete models. We present an application to railway where a light rail line is modelled (equipment and train). It is first equipped with a central interlocking then with a distributed interlocking for which we have obtained a Hardware in the Loop co-simulation, the source code being automatically generated from the models.
Speaker: Julien Ouy, ClearSy
We describe the iPP4CPPS experiment, funded under the CPSE Labs initiative with the UK and Germany South Design Centres. In this experiment we are applying multi-modelling and co-simulation techniques to the design of cyber-physical production systems. As output from the experiment we will evaluate the INTO-CPS technology and produce a physical demonstrator.

Co-simulation is a particularly promising approach for interoperable modular development of CPS. However, the integration and coupling of subsystems still represents an important challenge and requires faithful consideration. This contribution discusses integration challenges and highlights current developments along an experiment and standardization attempts.
Speaker: Martin Benedikt, Virtual Vehicle
In the CPSBudi (Multidisciplinary design of Cyber-Physical Systems for smart energy control in Buildings and Districts) experiment we are developing a co-simulation infrastructure for the smart and energy-efficient buildings domain. For developing this co-simulation infrastructure multi-disciplinary design and simulation tools for cyber-physical systems (Overture and Crescendo) are being integrated with domain-specific modelling and simulation tools such as Building Information Modelling (BIM) and EnergyPlus simulator. This way it will be possible to perform proper modelling and design of control systems as well as proper modelling and simulation of domain-specific aspects.

Cyber-Physical Systems (CPSs) can be found in a wide range of areas and domains (e.g., railway, aerospace or medical). To support clients’ customization, many companies are adopting product line engineering methodologies to develop CPSs. As a result, variability of the systems increases, leading the CPSs to be configurable into thousands or even millions of configurations. These methods, despite bringing many advantages, they make challenging to test the CPSs. These is, to a large extent, caused by the fact that not every single configuration can be tested. In this talk we will present the methodologies and tools we developed to efficiently test CPS product lines. Specifically, search-based software engineering methods were adopted to automatically generate, select and prioritize test cases for CPS product lines. The tool Simulink was employed to execute the test cases. The empirical results suggest that the proposed methods significantly outperform the baseline algorithms.

Engineering complex Cyber-Physical Systems such as embedded control systems for emission reduction from large marine engines, it can be worthwhile to develop models using different tools for different purposes of the physical and cyber aspects that can be used to validate different properties. However, it is non-trivial to be able to combine such different models of different constituent elements. In order to reduce the need for expensive tests with the real system it is an advantage to be able to combine such heterogeneous models in a joint co-simulation in order to reduce the overall costs of validation. A case-study demonstrates how that can be achieved for a commercial system developed by MAN Diesel \& Turbo, using a newly developed tool chain based on FMI and INTO-CPS supporting different operating systems. The generality of the suggested approach also enables future usages incorporating constituent models supplied by sub-suppliers protecting their Intellectual Property.
