Towards an ISO 26262-compliant OSLC-based Tool Chain Enabling Continuous Self-Assessment

摘要

Manufacturers of road vehicles have to comply with the functional standard ISO 26262. This standard requires the creation of a safety case, which compiles all the work products of the life-cycle in a traceable manner. The creation of a safety case is extremely time-consuming. Its creation is needed for the purpose of self-assessment in order to manage the liability risk. To speed up such creation, semi-automatic generation represents an interesting solution. OSLC (Open Services for Lifecycle Collaboration) is a recently introduced standard aimed at enabling life cycles tools interoperability via production/consumption of resources. OSLC defines a set of domains, each of which focuses on a single and generic phase of the life-cycle. To create an ISO 26262- compliant tool chain, such domains need to be extended and or replaced. In this paper, we present the first step towards the extension of such domains. First we establish the guidelines to define an ISO 26262-compliant OSLC-based knowledge domain, aimed at enabling the production and consumption of resources related to verification work products. Then, we propose our domain and we instantiate it to represent the verification-related resources of a real system. Finally, we discuss how this domain has been validated and how it can be used for continuous self-assessment.
