IEC 61508 is the mother of all standards for functional safety. Many standards including ISO 13849, ISO 26262 or IEC 61511 are derived from IEC 61508. These standards are relatively complex but they need to be used in practice, no matter how complex the hardware and software components of a system.
The Functional Safety Forum (7-9 July 2015) addresses different topics from the perspective of application providers and the automotive industry to provide answers to the most important questions. You can listen to interesting lectures about hardware and software components, tools and resources, and certification. You can learn more about the practical use of secure systems in production and in the automobile industry.
Questions you might run into at Functional Safety Forum 2015 are the following:
- Must every device meet the highest safety requirements?
- What are the different security levels and what are the differences between them?
- What standards are relevant?
- How to ensure the safety of a system?
- How do the development processes of companies meet the requirements of the standards?
- What qualities should software tools have?
- What evidence must be provided and who can certify?
- Do certificates protect from legal consequences?
- What role does data play in functional safety?
With the aim to provide a comprehensive picture of the functional safety, the forum will provide clearly structured information for developers of hardware and software components as well as for integrators and end users of functional safe systems.
We invite you to a great speech about Safety-related development with the help of STPA and codeBeamer
Speaker: Monika Reif, Institute of Applied Mathematics and Physics, Zurich University of Applied Sciences
What you can learn (Abstract of the speech of Monika Reif):
There are more and more regulations and industries where safety standards are to be applied. It increases the demands of manufacturers and their suppliers to reduce potential security risks.The various functional safety standards (IEC6150, ISO26262, EN 50 129, etc.) require the verification of the system or component used during the development and to meet the requirements of the functional safety. To detect whether a system design meets the safety requirements, various methods are used.
We are going to introduce a new method. We are going to show how to analyze potential hazards of system design with the new method called STPA (Systems-Theoretic Analysis Process). The method is based on the idea of systems theory and was developed at MIT.
While traditional methods have emerged from reliability engineering and they focus on avoiding component failure, the STPA has been developed to investigate errors caused by the interaction of component failure. On the other hand, events are analyzed that are the result of the interaction of intact components or unsafe interactions. This method has been successfully used in various industries such as Automotive, Defense, Medical as well as Aerospace.
We are going to introduce a way to apply this method within a reasonable amount of time. In this new approach, the hierarchical control structure can be derived from a SysML diagram in order to perform the analysis. To ensure traceability and consistency between all safety-related work products is often the difficulty of the safety-related system development. The continuous traceability of the products exists and the proof is possible but each request should be validated and any intolerable risks should be minimized. We should be compliant with requirements for change management, which must be done in addition to an analysis of the impact of changes on safety-related functions and the documentation of the changes.
We are going to introduce you company Intland Software and codeBeamer ALM that ensures compliance of requirements for the safety-oriented development process up to ASIL-D or SIL3 and that provides several interfaces for the integration of existing work products.
