Enhancing Model-Based Engineering of Product Lines by Adding Functional Safety
نویسندگان
چکیده
Today’s industrial product lines in the automotive and construction equipment domain face the challenge to show functional safety standard compliance and argue for the absence of failures for all derived product variants. The product line approaches are not sufficient to support practitioners to trace safety-related characteristics through development. We aim to provide aid in creating a safety case for a certain configuration in a product line such that overall less effort is necessary for each configuration. In this paper we 1) discuss the impact of functional safety on product line development, 2) describe a model-based approach to capture safety-related characteristics during concept phase for product lines and 3) discuss the usefulness of our proposal.

Design of a New IPFC-Based Damping Neurocontrol for Enhancing Stability of a Power System Using Particle Swarm Optimization
The interline power flow controller (IPFC) is a concept of the FACTS controller for series compensation which can inject a voltage with controllable magnitude and phase angle among multi lines. This paper proposes a novel IPFC-Based Damping Neuro-control scheme using PSO for damping oscillations in a power system to improve power system stability. The addition of a supplementary controll...
متن کاملSafety analysis of software product lines using state - based modeling q
The difficulty of managing variations and their potential interactions across an entire product line currently hinders safety analysis in safety-critical, software product lines. The work described here contributes to a solution by integrating product-line safety analysis with model-based development. This approach provides a structured way to construct state-based models of a product line havi...

متن کاملProduct Line Analysis and the System Safety Process
Product lines (groups of highly similar products) have recently received a great deal of attention in the software engineering community, and especially in organisations that develop products that contain embedded software. The product-line concept provides a constrained production environment that facilitates change and reuse between members of the product line. The reported successes of the l...
متن کاملVROOM & cC: a Method to Build Safety Cases for ISO 26262-compliant Product Lines
ISO 26262 is a functional safety standard that targets the automotive domain. This standard focuses on single system certification and does not contain guidelines to certify product lines. Thus, to be ISO 26262-compliant, for each product of a product line, a company must provide almost from scratch all the work products required by the standard, including a safety case. Current product lines e...
