| Summary: | The safety is considered one of the most critical
issues in the design of cyber-physical systems (CPS). The
Software Product-Line (SPL) and reusable software
components are suitable approaches for CPS, which are often
re-engineered from existing systems. Currently, the influence
of architecture in assurance of software safety is being
increasingly recognized. However, the safety-based
architectural design methods are limited in SPLs because of
the complexity and variabilities existing in SPL architectures.
A new statechart-based safety pattern and adaptation of our
previous SPL Architecture design method are presented in this
paper. Also the paper describes a simplified safety assessment
model which is used to evaluate the safety improvement in the
design of the SPLA after using the proposed safety design
pattern. Finally, to illustrate the effect of the design pattern in
the PLA design, a simplified automated Electromechanical
Braking System (EBS) product line is used as a running
example. The results show that there is a considerable
improvement in the system safety design after using the
proposed safety pattern. |
