Abstract

The conception and design of Resource Constrained Embedded Systems (RCES) is an inherently complex endeavor. Non-functional requirements from security and dependability are exacerbate this complexity. Model-Driven Engineering (MDE) is a promising approach for the design of trusted systems, as it bridges the gap between design issues and implementation concerns. The purpose of process models is to document and communicate processes, as well as reuse them. Thus, processes can be better taught and executed. However, most useful metamodels are activity-oriented, and the required concepts of safety lifecycle, such as validation, cannot be easily modeled. In this paper, the authors propose a safety-oriented process metamodel that extends exiting framework to support all safety control requirements. A new safety lifecycle development processes technique has been built to ease its use in a building process of system/ software applications with safety support. As a proof of concept, the feasibility of the approach has been evaluated with an example. The example is an engineering process for building industry control systems with safety requirements for software and hardware resources. A prototype implementation of the approach is provided and applied to the example of industry control systems in the railway domain.
