DECISIONS ON RELIABILITY LEVEL AND SAFETY FACTOR FOR STRUCTURAL DESIGN

Reliability - based Structural Design

Reliability based structural design

According to ISO 2394, structures shall be designed, constructed and maintained in such a way that they are suited for their use during the design working life in an economic way. To fulfil this requirement one needs insight into the risk and reliability under expected and non-expected actions. A key role in this respect is played by the structural reliability analysis (SRA). In this paper the ...

From Safety Integrity Level to Assured Reliability and Resilience Level for Compositional Safety Critical Systems

Safety engineering standards define rigorous and controllable processes for system development. Nevertheless, safety standards differences from distinct domains are non-negligible. We focus in particular on the aviation, automotive and railway standards, all related to the transportation market. We argue that the Safety Integrity Levels are not sufficient to be used as a top level requirement f...

Bi-level Model for Reliability based Maintenance and Job Scheduling

Many defects in manufacturing system are caused by human resources that show the significance of the human resources in manufacturing systems. Most manufacturers attempt to investigate the human resources in order to improve the work conditions and reduce the human error by providing a proper work-rest schedule. On the other hand, manufacturer deal with machine scheduling based on demand and wo...

Managing Architectural Design Decisions for Safety-Critical Software Systems

In this paper, we propose a negative scenario framework along with a mitigation action model as the linkage between safety quality attribute and architecture definition. The scenario framework provides an effective means of formulating safety concerns. The mitigation action model facilitates exploitation and codification of existing safety-critical system design knowledge. Finally, we present a...
