An automated nD model creation on BIM models

Miroslav Vycital, Cenek Jarský
2020 Organization, Technology and Management in Construction: An International Journal  
AbstractThe construction technology (CONTEC) method was originally developed for automated CONTEC planning and project management based on the data in the form of a budget or bill of quantities.  ...  This article outlines a new approach in an automated creation of the discrete nD building information modeling (BIM) models by using data from the BIM model and their processing by existing CONTEC method  ...  Acknowledgment This work was financially supported by SGS17/165/ OHK1/3T/11 "Modeling of industrial robotic brick system."  ...

A Methodology for Automating Assurance Case Generation [article]

Shreyas Ramakrishna, Charles Hartsell, Abhishek Dubey, Partha Pal, Gabor Karsai
2020 arXiv   pre-print
To improve the current state of practice, we introduce a structured ACG tool which uses system design artifacts, accumulated evidence, and developer expertise to construct a safety case and evaluate it  ...  The certification processes for these systems are stringent and require robust safety assurance arguments and substantial evidence backing.  ...  ACKNOWLEDGEMENTS This work was supported in part by DARPA's Assured Autonomy project and Air Force Research Laboratory.  ...

Generation and Verification of Executable Assurance Case by Model-based Engineering

Fang Yan
2021 2021 IEEE International Symposium on Software Reliability Engineering Workshops (ISSREW)  
Assurance Cases (ACs) are used for justifying system confidence in important properties including safety, reliability, etc. Their manual generation is time-consuming and prone to errors.  ...  Thus, in this PhD, the Model-based Engineering (MBE) techniques are exploited for an automatic process for executable ACs. The first aim is to generate AC models automatically from system artefacts.  ...  But the system design data are not required to be models thus the method does not support the generation from system design models using model query. For FM verification of AC claims, Diskin et al.  ...

Formalism in Safety Cases [chapter]

John Rushby
2009 Making Systems Safer  
Suitable formalisms could allow the arguments of a safety case to be checked mechanically. We examine some of the issues in doing so.  ...  I am grateful to Robin Bloomfield and his colleagues at Adelard and City University for exposing me to some of these topics and sharing their own ongoing investigations.  ...  On the other hand, standards tend to be slow-moving and conservative, and can be a barrier to innovation in both system design and in methods for assurance.  ...
