A Model-Based Approach for Real-Time Systems Architecture Exploration

Abstract : Hardware/software based solutions play significant role in many domains like automotive or avionics. Complexity of such real-time distributed systems is substantial. Their design and implementation is a long-term and complex process. Reasonable approach is to create a framework that defines a set of viewpoints according to which the system can be specified and analysed. This paper presents a concept of a framework based on the SysML and MARTE languages. It provides the ability to guide the design by first, introducing the views and viewpoints which structure the overall design model and secondly by supporting certain design decisions such as allocation of functional entities onto hardware nodes or definition of a replication strategy for safety critical functions. These decisions have a high influence on non-functional properties related to system performance, cost and safety. Presented solution for the automated guidance is based on the evolutionary algorithms which prove to be efficient in solving complex problems.
