Model-based dependability analysis : state-of-the-art, challenges and future outlook

Abstract: Over the past two decades, the study of model-based dependability analysis has gathered significant research interest. Different approaches have been developed to automate and address various limitations of classical dependability techniques to contend with the increasing complexity and challenges of modern safety-critical system. Two leading paradigms have emerged, one which constructs predictive system failure models from component failure models compositionally using the topology of the system. The other utilizes design models - typically state automata - to explore system behaviour through fault injection. This paper reviews a number of prominent techniques under these two paradigms, and provides an insight into their working mechanism, applicability, strengths and challenges, as well as recent developments within these fields. We also discuss the emerging trends on integrated approaches and advanced analysis capabilities. Lastly, we outline the future outlook for model-based dependability analysis

DECODER - DEveloper COmpanion for Documented and annotatEd code Reference

Software is everywhere and the productivity of Software Engineers has increased radically with the advent of new specifications, design and programming paradigms and languages. The main objective of the DECODER project is to introduce radical solutions to increase productivity by increasing the abstraction level, at specification stage, using requirements engineering techniques to integrate more complete specifications into the development process, and formal methods to reduce the time and efforts for integration testing. DECODER project will develop a methodology and tools to improve the productivity of the software development process for medium-criticality applications in the domains of IoT, Cloud Computing, and Operating Systems by combining Natural Language Processing techniques, modelling techniques and Formal Methods. A radical improvement is expected from the management and transformation of informal data into material (herein called knowledge ) that can be assimilated by any party involved in a development process. The project expects an average benefit of 20% in terms of efforts on several use cases belonging to the beforehand mentioned domains and will provide recommendations on how to generalize the approach to other medium-critical domains.This work has been developed with the financial support of the European Union’s Horizon 2020 research and innovation programme under grant agreement No. 824231 and the Spanish State Research Agency under the project TIN2017-84094-R and co-financed with ERDF.Torres Bosch, MV.; Gil Pascual, M.; Pelechano Ferragud, V.

A NASA-wide approach toward cost-effective, high-quality software through reuse

NASA Langley Research Center sponsored the second Workshop on NASA Research in Software Reuse on May 5-6, 1992 at the Research Triangle Park, North Carolina. The workshop was hosted by the Research Triangle Institute. Participants came from the three NASA centers, four NASA contractor companies, two research institutes and the Air Force's Rome Laboratory. The purpose of the workshop was to exchange information on software reuse tool development, particularly with respect to tool needs, requirements, and effectiveness. The participants presented the software reuse activities and tools being developed and used by their individual centers and programs. These programs address a wide range of reuse issues. The group also developed a mission and goals for software reuse within NASA. This publication summarizes the presentations and the issues discussed during the workshop

Requirements, design and business process reengineering as vital parts of any system development methodology

This thesis analyzes different aspects of system development life cycle, concentrating on the requirements and design stages. It describes various methodologies, methods and tools that have been developed over the years. It evaluates them and compares them against each other. Finally a conclusion is made that there is a very important stage missing in the system development life cycle, which is the Business Process Reengineering Stage

Requirement Specification Stage of the Project Lifecycle of Computerized Systems & the Standards that Can Be Implemented

Understanding requirement specifications was an integral part of information systems design and was critical to the success of interactive systems. However, specifying these requirements was not simple to achieve. This research, including a literature review, describes general methods to support requirement specification analysis that can be adapted into a range of situations in accordance with relevant standards. The main techniques discussed were risk management, stage-based lifecycle models and frameworks. Additionally, as part of the methodology and project history, the methods for implementation, process improvements and schedule of the research was examined. A case study with statistical analysis was described to illustrate how these techniques, methods and standards have been applied in practice and the advantages and disadvantages experienced

SAGA: A project to automate the management of software production systems

The Software Automation, Generation and Administration (SAGA) project is investigating the design and construction of practical software engineering environments for developing and maintaining aerospace systems and applications software. The research includes the practical organization of the software lifecycle, configuration management, software requirements specifications, executable specifications, design methodologies, programming, verification, validation and testing, version control, maintenance, the reuse of software, software libraries, documentation, and automated management

Working Notes from the 1992 AAAI Workshop on Automating Software Design. Theme: Domain Specific Software Design

The goal of this workshop is to identify different architectural approaches to building domain-specific software design systems and to explore issues unique to domain-specific (vs. general-purpose) software design. Some general issues that cut across the particular software design domain include: (1) knowledge representation, acquisition, and maintenance; (2) specialized software design techniques; and (3) user interaction and user interface
