“…The paper outlined the three phases of the procedure and included a sample industrial study with a coffee maker to support the result of their studies (Muller et al, 2016). The approach was developed to help with the stricter safety regulations, increasing complexity of the systems, and shorter development cycles (Muller et al, 2016).…”

“…It is possible to infer that the proposed procedure results in the consideration of safety aspects experiencing an inevitable shift towards the earlier stages of a design process. The authors proposed that a common SysML model at an earlier stage in system design can be used to simultaneously model the system and conduct a functional hazard analysis (Muller et al, 2016). With regards to MBSE, a combination of functional and component architecture: a new "Hazard Analysis" profile was developed (Muller et al, 2016).…”

“…Phase one involves identifying the requirements, use cases and misuse cases (Muller et al, 2016). Use cases are the list of actions between a role and the system to achieve a goal while misuse cases are the process of executing a malicious act or abuse towards the system.…”

“…In this phase, specifications for requirements, use cases, and misuse cases are identified (Roth, 2016). The required parameters for the safety analysis would be set, and ideally, it would be more efficient and accurate to have defined criteria for comparison within the process (Muller et al, 2016). The second phase works with functional architecture, utilizing a dynamic perspective (Roth, 2016).…”

Two methodologies used in aircraft system developments are Model-Based Safety Analysis (MBSA), which assesses the safety risk associated with design in later stages, and Model-Based Systems Engineering (MBSE), a process that creates the domain models to help design a system. With the continuous growing use of both methodologies, it is inevitable that they will become linked to improve the design process from many aspects. This review identifies and proposes potential links for the integration of MBSA and MBSE by using the V-model of MBSA, thereby resulting in more effective design processes and reduced development costs. The paper addresses a general interpretation of the topic and supplementary case studies within the industry regarding both methodologies. Some benefits of the link between MBSA and MBSE include: utilisation of a wider range of analysis tools, automated communication of important definitions, consistency between both ends, and a potential improvement in confidence regarding design. As this is a preliminary proposal regarding the best approach for using MBSA in combination with MBSE, further research should be performed into the areas of formalized language, defining systems requirements for the usage of this approach, and relationships with the existing regulations and compliance needs.Deux méthodes utilisées dans le développement des avions sont l'Analyse de sécurité basée sur des modèles (ASBM), qui évalue les risques de sécurité associés avec la conceptualisation d'étapes antérieures, et l'Ingénierie des systèmes basée sur des modèles (ISBM), un processus qui crée des modèles de domaine pour concevoir un système.Avec l'utilisation croissante des deux méthodes, il est inévitable qu'elles seront liées pour améliorer le processus de conceptualisation de plusieurs aspects. Cette revue identifie et propose des liens potentiels qui pourraient intégrer l'ASBM et l'ISBM, en utilisant le model-V de MBSA, résultant ainsi en des processus de conceptualisation plus efficaces et des coûts de développement réduits. L'article adresse une interprétation générale du sujet et des études de cas supplémentaires dans l'industrie qui concernent les deux méthodes de développement. Certains des avantages du lien entre ASBM et ISBM incluent: l'utilisation d'une grande gamme d'outils d'analyse, la communication automatisée de définitions importantes de conceptualisation, la cohérence entre les deux extrémités, et une confiance améliorée dans la conceptualisation. Comme ceci est une proposition préliminaire concernant la meilleure approche pour combiner l'ASBM et l'ISBM, de plus amples recherches devraient être menées dans les domaines du langage formel, les exigences des systèmes pour utiliser cette approche, les relations avec les règlements actuels et les exigences pour la conformité.

To address growing system complexity in the aerospace industry, a Model‐Based Systems Engineering (MBSE) approach has been increasingly adopted for the development of aircraft systems. This calls for a corresponding approach for performing safety assessment to maintain consistency between the system and safety domains. One of the key safety assessment processes for aircraft development is the Functional Hazard Assessment (FHA). The purpose of this paper is to build upon previously published works and introduce the MBFHA framework which describes the language, method, and tool needed for implementing a model‐based approach to performing FHA and integrating it into MBSE activities. A customised FHA profile is introduced for the modelling language, an overall workflow along with processes for FHA report and safety requirements generation is presented for the method, and a list of tool constraints is provided. A proof‐of‐concept is subsequently presented using safety data for the landing gear extension and retraction system of a generic business aircraft.

Model‐based systems engineering is a powerful methodology to develop safety‐critical systems. The use of the system model as a single source of truth for risk and dependability analysis results in a consistent and complete assessment. Besides, representation and logging of the assessment within the model result in a complete and up‐to‐date single source of information that can be used during the device certification as well. This paper aims to provide a comprehensive risk management SysML profile that includes interconnected safety analysis [functional hazard assessment (FHA), fault tree, and failure mode and effect analysis (FTA, FMEA)], control measure, and evaluation model elements in compliance with the medical standards. Model‐based risk assessment of a point‐of‐care diagnostic device for sepsis has been shown as a case study to show the implementation of the profile. This device is a standalone unit and the test results obtained directly affect the patient. Therefore, both the top‐down (FHA and FTA) and bottom‐up (FMEA) safety assessment methods have been used. Another objective of the study is to define a systematic and holistic method to perform fault tree analysis, not only from the system architecture models but also from the functional, activity, and sequence diagrams of the system model.
