An Architecture Modeling Method for Supporting Reliability-based Risk Analysis of Ship Command and Control Systems

摘要

Architectural level reliability-based risk analysis is important for finding risky components during the early stage of developing Ship Command and Control Systems (SCCSs). Therefore, an Architecture Modeling Method (AMM) for supporting reliability-based risk analysis of SCCSs is needed. In previous studies, a generic framework was proposed to derive AMMs for large-scale software-intensive systems. The framework has been applied to derive an AMM (named as SAMM) for supporting architecture description during the development process of SCCSs. In this study, based on the framework, an AMM is defined to support reliability-based risk analysis of SCCSs by extending SAMM, named as SAMM4RRA. SAMM4RRA contains one architecture viewpoint and 11 models and an UML/SysML-based architecture description language. An industrial application of SAMM4RRA, along with the subsequent application of the derived SAMM4RRA architecture model (i.e., a deployed SCCS prototype) was conducted to evaluate SAMM4RRA. Results show that SAMM4RRA meets all the requirements for describing the architecture of SCCSs with the purpose of supporting reliability-based risk analysis.
