• Towards Safety Case Integration with Hazard Analysis for Medical Devices

  Publikacja

  • A. Wardziński
  • A. Jarzębowicz

  - Rok 2016

  Safety case is one of system safety lifecycle products and should be consistent with other lifecycle products like hazard analysis results. In this paper we present a method of safety case integration with hazard tables based on the use of parametrized argument patterns. We describe a hazard table metamodel, a safety argument pattern and a mechanism of pattern instantiation using a linking table which represents references to system...

• Uniform Model Interface for Assurance Case Integration with System Models

  Publikacja

  • A. Wardziński
  • P. Jones

  - Rok 2017

  Assurance cases are developed and maintained in parallel with corresponding system models and therefore need to reference each other. Managing the correctness and consistency of interrelated safety argument and system models is essential for system dependability and is a nontrivial task. The model interface presented in this paper enables a uniform process of establishing and managing assurance case references to various types...

• Support for argument structures review and assessment

  Publikacja

  • Ł. Cyra
  • J. Górski

  - RELIABILITY ENGINEERING & SYSTEM SAFETY - Rok 2011

  Argument structures are commonly used to develop and present cases for safety, security and for other properties of systems. Such structures tend to grow excessively, which causes problems with their review and assessment. Two issues are of particular interest: (1) systematic and explicit assessment of the compelling power of an argument, and (2) communication of the result of such an assessment to relevant recipients. The paper...

• Extending GQM by argument structures

  Publikacja

  • Ł. Cyra
  • J. Górski

  - Rok 2007

  Effective metrics definition methods are of particular importance, as measurement mechanisms are indispensable in virtually any engineering discipline. The paper describes how the well known Goal-Question-Metric (GQM) method of systematic metrics derivation from measurement goals can be extended by applying argument structures. The proposed approach is called Goal-Argument-Metric (GAM). We briefly introduce general ideas of GQM...

  - Rok 2012

  Structured arguments based on evidence are used in many domains, including systems engineering, quality assurance and standards conformance. Development, maintenance and assessment of such arguments is addressed by TRUST-IT methodology outlined in this paper. The effective usage of TRUST-IT requires an adequate tool support. We present a platform of software services, called NOR-STA, available in the Internet, supporting key activities...

• Using argument structures to create a measurement plan

  Publikacja

  • Ł. Cyra
  • J. Górski

  - POLISH JOURNAL OF ENVIRONMENTAL STUDIES - Rok 2007

  While planning an experiment the same question always arises: What are the goals of the experiment and which measurements are needed to demonstrate that the goals have been achieved? Deciding about the extent of raw data to be collected, the metrics to be constructed on those data and the interpretation of the metrics with respect to the assumed goals is by no means a trivial task. In this paper we show how a well known Gal-Question-Metrics...

  The dataset represents the results of an example of functional safety analysis systems is presented below. It is based on a control system, which consists of some basic components like sensors, programmable logic controllers and valves. It is a part of petrochemical critical installations. The communication between sensor logic controllers and actuators...

• Road safety analysis in Poland using time-series modelling techniques

  Publikacja

  • J. Żukowska

  - Journal of Polish Safety and Reliability Association, Summer Safety and Reliability Seminars - Rok 2013

  A number of international studies argue that there is a correlation between the number of traffic fatalities and the degree of public activity. The studies use the unemployment rate to support that argument. As unemployment grows miles travelled fall, a factor known to affect road safety. This relationship seems to be true for Poland, as well. The model presented in the paper is intended to prove it. It is a structural time-series local...
