Quality model based on ISO/IEC 9126 for internal quality of MATLAB/Simulink/Stateflow models

In a model-based approach, models are considered as the prime artefacts for the software specification, design and implementation. Quality assurance for program codes has been discussed a lot, however equivalent methods for model quality assessment remain rareness. Assessing quality is of particular importance for technical models (e.g. MATLAB/Simulink/Stateflow models), since they are often used for production code generation. Our main contribution is a quality model based on ISO/IEC 9126, which defines the internal model quality as well as measures for the assessments. Our quality model shall not only show improvement potentials in model, but also provide evidence about quality evolution of a model.
