Integrating Systems Safety into Systems Engineering during Concept Development

Closing gaps: integrating food safety management systems into the veterinary curriculum, as a tool to improve food quality and trade

Including Safety during Early Development Phases of Future Air Traffic Management Concepts

Safety should be designed into future air traffic management systems from their very conception, which can be achieved by integrating powerful hazard analysis techniques into the general systems engineering process. The primary barrier to achieving this objective is the lack of effectiveness of the existing analytical tools during early concept development. This paper introduces a new technique...

Safety - driven Early Concept

As aerospace systems become increasingly complex and the roles of human operators and autonomous software continue to evolve, traditional safety-related analytical methods are becoming inadequate. Traditional hazard analysis tools are based on an accident causality model that does not capture many of the complex behaviors found in modern engineered systems. Additionally, these traditional appro...

Toward Integrating a System Theoretic Safety Analysis in an Agile Development Process

Agile development methodologies are becoming a tendency in today’s changing software development. However, due to a lack of safety assurance activities, especially safety analysis, agile methods are criticized for being inadequate for the development of safe software. In this paper, we introduce an agile ”Safe Scrum” by mapping a novel systematic safety analysis method, called STPA (System-Theo...

Model-based Concurrent Systems Design for Safety

This article describes a model of concurrent systems design for developing safety-critical systems. The developed model integrates system design, system safety analysis, and human factors. The model is able to develop the specifications for safety-critical systems easily. System safety analysis is a crucial part of the system effectiveness analysis for safety critical systems that require a con...
