Abstract [en]

Cyber-Physical Systems (CPS) have evolved continuously over the past decades with increasing functional and technical complexity. As a consequence, the development typically involves more complex interactions of designers and stakeholders compared to the past. We are in particular investigating a framework for model-driven and tool-integration for developing the complex system, such as aircraft, aero engines and automotive vehicles. Normally, such complex system can be divided into different parts with associated engineering tasks allocated to different work groups or companies. These groups often use specific domain-specific simulator tools to assist the specification, analysis and synthesis tasks. For example, when a whole vehicle is designed, the overall system behavior and other properties depend on the characteristics of its subsystems and components being composed. It is therefore important for system developers to conduct early system integration and thereby to understand the system behaviors and analyze system performance in the initial design phases. In current industrial practices, different CAD and CAE tools are used for the development of CPS subsystems and components, such as for requirement analysis, high level design, detailed level design, implementation, testing, etc. Since the subsystem designers often use their own tools to build models, it is a challenge for the system developers to integrate those detailed models and to predict the whole system performance. This calls for a complete integration framework for different models and tools while taking the process management perspective into consideration.

This paper describes an initial version of a framework for co-simulation and tool-integration in regard to the methodology and technical roadmap. Co-simulation is supposed as a simulation and analysis approach to verify the system requirements. With co-simulation we refer to an approach integrating subsystem models in order to predict the whole complex system performance. The framework is inspired by the SPIT model, [1]. In the framework, a formal system description is provided to share information among various stakeholders, including project managers, system engineers, modelers, system designers and simulation testers. The content of system information being described and integrated includes requirements, parameter setting, interface contracts, and tool specific information for co-simulation. Also, parameters related to optimized simulation behaviors can be added.
