Measurement Technique to Evaluate Model- Based Tools for Safety Critical Embedded Systems

Abstract

Model-based systems engineering is a state of art engineering process being adopted by industry all over the world to develop a safe, reliable, maintainable and available system. Industry standards like IEC 61508, EN50128 and RTCA DO-178C recognize the capabilities of the model-based approach for an effective engineering process performance. There are number of model-based tools available in the market and the selection of an appropriate tool is very critical for the success of the project. Hence there should be benchmark to select the appropriate tool for the project. This paper provides a measurement technique for evaluating model-based tools based on the tool features like its applicability, portability, scalability, and compatibility, conformance to standards, versioning and reporting to name a few. The effectiveness of the techniques proposed is evaluated for a proven system as a case study. The outcome provides the metrics for the selection of appropriate tool for an application and probable combination of tools that can be used in various phases of the life cycle. The proposed technique helps in selection of the most appropriate tool for a particular application based on the project schedule, budget and safety requirements resulting into an effective process.
