Abstract:
Any study or project within the framework of system design has chosen to start the modeling phase with the model-based systems engineering approach (MBSE), it will encounter decision-making difficulties of the approach. to adopt. During the last two decades, many MBSE methodologies have been developed, but the majority of them present an incomplete or abstract architectural framework for organizing the modeling work. The MBSE Grid based Systems Modeling Language (SysML) approach has made the modeling task easier for system engineers. Indeed, SysML constitutes a powerful tool, using its diagrams, to model the points of view according to the principle of development of requirement, behavior or structure of the system. This paper summarizes the MBSE methodologies most used in research work and development projects. In the context of our study, the MBSE Grid approach is adopted with slight modifications concerning the names of the domains of the grid. By combining with Bombardier Transport SysMM's MBSE methodology, which consists of three main phases, the proposed MBSE grid presents a modeling approach by analysis: operational, functional and technical of the system. The purpose of this work is to conduct an operational analysis, for the implementation of a Health Monitoring and Management Unit (HMMU) of a hydropower group. Keywords—MBSE, MBSE Grid, Operational Analysis, SysML Hydroelectric group

Abstract:
AbstractModel-Based Systems Engineering (MBSE) is an efficient approach to support product development in order to meet today's challenges. The MBSE approach includes methods and, above all, modelling approaches of the technical system with the aim of continuous use in development. The objective of this paper is to use the potential of the MBSE models and to show the added value of such models on the system level when used as a single source. With this objective, this paper presents a three-step approach to systematically identify and apply meaningful modelling approaches within MBSE, based on the needs during the development process. Furthermore, an FMEA example is included in this paper to elaborate the use of MBSE in the system failure analysis.

Abstract:
Model-Based Software Engineering (MBSE) is an architecture-based software development approach. Agile, on the other hand, is a light system development approach that originated in software development. To bring together the benefits of both approaches, this article proposes an integrated Agile MBSE approach that adopts a specific instance of the Agile approach (i.e., Scrum) in combination with a specific instance of an MBSE approach (i.e., Model-Based System Architecture Process—“MBSAP”) to create an Agile MBSE approach called the integrated Scrum Model-Based System Architecture Process (sMBSAP). The proposed approach was validated through a pilot study that developed a health technology system over one year, successfully producing the desired software product. This work focuses on determining whether the proposed sMBSAP approach can deliver the desired Product Increments with the support of an MBSE process. The interaction of the Product Development Team with the MBSE tool, the generation of the system model, and the delivery of the Product Increments were observed. The preliminary results showed that the proposed approach contributed to achieving the desired system development outcomes and, at the same time, generated complete system architecture artifacts that would not have been developed if Agile had been used alone. Therefore, the main contribution of this research lies in introducing a practical and operational method for merging Agile and MBSE. In parallel, the results suggest that sMBSAP is a middle ground that is more aligned with federal and state regulations, as it addresses the technical debt concerns. Future work will analyze the results of a quasi-experiment on this approach focused on measuring system development performance through common metrics.

Abstract:
AbstractModel-Based Systems Engineering (MBSE) is increasingly used across industries for the integrated modelling of complex systems to support model-based development and provide enhanced traceability between requirements and verification and validation of the system. This paper seeks to strengthen the function modelling methodology in MBSE by introducing an approach based on flow heuristics guided by the System State Flow Diagram schema. This provides function representations with an enhanced integrity in MBSE facilitating the solution-agnostic architecture modelling, and supports integrated simulation and function failure reasoning based on MBSE. The approach is illustrated with a case study of an electric bicycle implemented in the MathWorks System Composer environment.

Abstract:
Developing modern products involves numerous domains (controlling, production, engineering, etc.) and disciplines (mechanics, electronics, software, etc.). The products have become increasingly complex while their time to market has decreased. These challenges can be overcome by Model-Based Systems Engineering (MBSE), where all development data (requirements, architecture, etc.) is stored and linked in a system model. In an MBSE system model, product requirements at the system level can lead to numerous technical variants with conflicting objectives at the parameter level. To determine the best technical variants or tradeoffs, Multidisciplinary Analysis and Optimization (MDAO) is already being used today. Linking MBSE and MDAO allows for mutually beneficial synergies to be expected that have not yet been fully exploited. In this paper, a new approach to link MBSE and MDAO is proposed. The novelty compared to existing approaches is the reuse of existing MBSE system model data. Models developed during upstream design and test activities already linked to the MBSE system model were integrated into an MDAO problem. Benefits are reduced initial and reconfiguration efforts and the resolution of the MDAO black-box behavior. For the first time, the MDAO problem was modeled as a workflow using activity diagrams in the MBSE system model. For a given system architecture, this workflow finds the design variable values that allow for the best tradeoff of objectives. The structure and behavior of the workflow were formally described in the MBSE system model with SysML. The presented approach for linking MBSE and MDAO is demonstrated using an example of an electric coolant pump.

Abstract:
AbstractAlthough the application of model‐based systems engineering (MBSE) is an alternative for designing digital twins (DTs), MBSE possesses a steep learning curve, and quite often companies struggle to translate its theoretical benefits into their reality. Furthermore, the challenge of determining the DT model's fidelity, which brings balance between simulation accuracy and development costs, increases the modelling task difficulty. This paper presents the initial results from the research into facilitating the design of a system‐based DT, where various models are combined to obtain the desired representation of reality. The main contribution of this paper is towards MBSE practice, where a simplified eight‐step MBSE modelling approach for system‐based DTs is proposed. The modelling approach begins with the existing physical product and the need for a DT and results in a simulation model that constitutes the core of an actionable virtual twin. To shorten the MBSE learning curve, a set of guidelines is proposed to delimitate the Systems Modelling Language (SysML) use in Eclipse Papyrus, and a Python parser was built to convert the SysML models' information into the simulation model. The approach, guidelines and parser are analysed via an application example. In this example, the model's creation, validation and use are illustrated. The initial results indicate that the approach and modelling guidelines provide the necessary scaffolding for simplifying and facilitating MBSE application and SysML use in the design of system‐based DTs.

Abstract:
In the face of ever-increasing complexity of systems and system development programs, several aerospace, automotive, and defense organizations have already begun or are contemplating the transition to model-based systems engineering (MBSE). The key challenges that organizations face in making this decision are determining whether it is technically feasible and financially beneficial in the long-run to transition to MBSE, and whether such transition is achievable given budgetary constraints. Among other cost drivers of this transition, are a new digital infrastructure, personnel training in MBSE, and cost-effective migration of legacy models and data into the new infrastructure. The ability to quantify gains from MBSE investment is critical to making the decision to commit to MBSE implementation. This paper proposes a methodological framework for analyzing investments and potential gains associated with MBSE implementation on large-scale system programs. To this end, the MBSE implementation problem is characterized in terms of: system complexity, environment complexity and regulatory constraints, and system lifespan. These criteria are applied to systems in twelve major industry sectors to determine MBSE investment and expected gains. Results from this cost-benefit analysis are used to justify investment in MBSE implementation where warranted. This approach is generic and can be applied to different sectors for economic evaluation of costs and benefits and justification of transition to MBSE if warranted.

Abstract:
Abstract An effective and efficient New Product Development (NPD) and implementation process is crucial for creation of competitive advantage for each company. Due to this fact, companies are more and more often looking for methods and tools for improvement of NPD processes. The paper deals with an integrated Model Based Systems Engineering (MBSE) and lean approach to NPD. The individual stages of the NPD process are predisposed to different degrees to the use of MBSE and Lean. The research conducted shows that the use of advanced MBSE and lean tools and techniques in the development of new products is not widespread. There is a room for future research.

Abstract:
Nowadays, several manufacturing systems are evolving towards a greater collaboration between human and robots. The development of such systems requires integrated design tasks involving many disciplines and domains such as systems engineering, safety analyses and multi-physics. Furthermore, the increasing presence of multiple and structured requirements makes the use of models inevitable during the designing phases and also strongly helpful during other phases of the system life-cycle. Besides, for a better efficiency, there is an increasing demand to have a Digital Twin of the system to be used for different purposes such as design improvements by playing different scenarios, virtual commissioning and controlling maintenance activities. In this paper, we first summarize the research context, the reference methodologies, and the emerging needs for Digital Twin creation. Then, we apply a design approach including Model-Based Systems Engineering (MBSE), Model-Based Safety Assessment (MBSA) and multi-physics modeling for the design of a collaborative workplace for the assembly of Electro-Mechanical Actuators on an aircraft wing. An operational flow to integrate MBSE, MBSA and multi-physics modelling activities is provided. Then, after having identified some relevant scientific barriers, we provide a meta-model for system models integration within a digital twin framework.

Abstract:
AbstractSystems engineering activities in the concept and development phases have evolved continuously for decades. The deployment of digital thread, digital engineering, MBSE approaches, and modeling and simulation techniques have driven part of this evolution.Despite this trend, requirements are still largely textual and expressed in natural language, and requirements engineering activities are still often document‐based. However, model‐based requirements‐engineering approaches have emerged in recent years and have demonstrated significant benefits, including improved requirements quality, less ambiguity, and early and efficient verification and validation.The goal of this paper is to present the current outcomes and perspectives of setting up an Integrated Digital Requirements Engineering approach as developed within our company. This approach seeks to optimize usability and maximize benefits to support end‐to‐end V&V activities while fully integrating into MBSE workflows.

Abstract:
AbstractThe Japan Aerospace Exploration Agency (JAXA) has been implementing phased and progressive demonstrations of the Model‐Based Systems Engineering (MBSE) applications, using small demonstration satellite series, so called the Rapid Innovative Payload Demonstration Satellite (RAISE), as a demonstration pre‐cursor. The purpose of the activity is to establish a practical methodology of the MBSE application to satellite projects, to promote its practices, and to infuse MBSE to the Japanese space community. These RAISE satellites are 100kg‐class flagships in the Innovative Satellite Technology Demonstration Program, which provides on‐orbit demonstration opportunities for new technologies and key‐components. This paper presents the phased demonstration strategy, an overall approach, and the technology development of a system model being built for the full application of MBSE to RAISE‐4. For the technology development, the paper covers framework, modeling scope, system model building, system model collaboration with analysis/simulation tool, introduction of design rationale and concerns, information sharing through OpenMBEE, for our full application of MBSE.

Abstract:
AbstractA myriad of industries is investigating and applying new technologies, approaches, and software to improve the systems engineering life cycle status quo, by reducing the time duration and lowering the cost incurred in the systems engineering process. One effort undertaken, and described herein, is pairing an Agile‐Lean framework with models‐based systems engineering (MBSE) to achieve time saving and cost efficiencies quickly within systems engineering concepts to production systems phases. This is being done by the Agile Processes and technologies (APT) team who are tasked to deliver a weapon prototype in three years. For this purpose, APT has adopted practices currently used in industry to speed up the conventional processes and practices within Los Alamos National Laboratory and partners, particularly by implementing Agile‐Lean within MBSE. APT has demonstrated agility by implementing changes at the organizational scale; given that most of the work done at the facilities is heavily based on design and hardware performance. In addition, MBSE is used to support verification and validation activities to drive acquisition of necessary evidence to establish traceability and compliance needed for qualification and certification, as per stakeholders' requirements. This paper describes the current efforts towards implementing MBSE in an Agile‐lean framework to represent a complex system —weapon prototype—, in a rapidly moving and changing environment to enable informed decisions through the identification and capture of useful decision criteria.

Abstract:
Model based systems engineering (MBSE) is becoming a promising approach for the system-level design of complex mechatronics. And several MBSE tools are developed to conduct system modeling. However, the system design cannot be optimized in current MBSE tools. In this study, an approach is presented to conduct the task. A set of optimization stereotype is defined at first which is used to formalize the optimization model based on the system design model. Then the design parameters and their relationships applied optimization stereotypes are extracted and transferred to construct the tool-dependent optimization model. Finally, the optimization model is solved and the results are given back and then modify the corresponding system model automatically. In this paper, MagicDraw is used to model the whole system whereas Matlab optimizer is used for optimization. The combustion engine is chosen as the example to illustrate the proposed approach.

Abstract:
This paper presents how Model-Based System Engineering (MBSE) could be leveraged in order to mitigate security risks at an early stage of system development. Primarily, MBSE was used to manage complex engineering projects in terms of system requirements, design, analysis, verification, and validation activities, leaving security aspects aside. However, previous research showed that security requirements and risks could be tackled in the MBSE model, and powerful MBSE tools such as simulation, change impact analysis, automated document generation, validation, and verification could be successfully reused in the multidisciplinary field. This article analyzes various security-related techniques and then clarifies how these techniques can be represented in the Systems Modeling Language (SysML) model and then further exploited with MBSE tools. The paper introduces the MBSEsec method, which gives guidelines for the security analysis process, the SysML/UML-based security profile, and recommendations on what security technique is needed at each security process phase. The MBSEsec method was verified by creating an application case study that reflects real-world problems and running an experiment where systems and security engineers evaluated the feasibility of our approach.

Abstract:
AbstractObjective of this contribution is to present the use of Model-based Systems Engineering within the engineering design community. Based on a differentiation between SE and MBSE, the definition of three core MBSE elements, namely modelling method, modelling language, and modelling tool as well as the three major aspects of a consistent system model (requirements, behaviour, and structure) a structured review is conducted, focussing on the understanding and motivation as well as the modelling of systems. The review includes 93 publications from Design Society library and proceedings of the CIRP Design conferences during the period from 2011 to 2022. The review points out, that there is an increasing application of MBSE within the engineering design community, mainly focussing on architecture definition or combined engineering activities. Only a small portion of works (16 publications) are providing a consistent approach as these publications link all aspects of the system model and consider all three MBSE elements. It can be concluded, that there is a diffuse understanding of MBSE and different motivations are given to apply more formal system models as well as modelling tools.

Abstract:
AbstractThe process of generating FMEA following document-centric approach is tedious and susceptible to human error. This paper presents preliminary methodology for robotic manufacturing process modelling in MBSE environment with a scope of automating multiple steps of the modelling process using ontology. This is followed by the reasoning towards automatic generation of process FMEA from the MBSE model. The proposed methodology allows to establish robust and self-synchronising links between process-relevant information, reduce the likelihood of human error, and scale down time expenses.

Abstract:
Advanced driver assistance and automated driving systems must operate in complex environments and make safety-critical decisions. Resilient behavior of these systems in their targeted operation design domain is essential. In this paper, we describe developments in our Model-Based Systems Engineering (MBSE) approach to develop resilient safety-critical automated systems. An MBSE approach provides the ability to provide guarantees about system behavior and potentially reduces dependence on in-vehicle testing through the use of rigorous models and extensive simulation. We are applying MBSE methods to two key aspects of developing resilient systems: (1) ensuring resilient behavior through the use of Resilience Contracts for system decision making; and (2) applying simulation-based testing methods to verify the system handles all known scenarios and to validate the system against potential unknown scenarios. Resilience Contracts make use of contract-based design methods and Partially Observable Markov Decision Processes (POMDP), which allow the system to model potential uncertainty in the sensed environment and thus make more resilient decisions. The simulation-based testing methodology provides a structured approach to evaluate the operation of the target system in a wide variety of operating conditions and thus confirm that the expected resilient behavior has indeed been achieved. This paper provides details on the development of a utility function to support Resilience Contracts and outlines the specific test methods used to evaluate known and unknown operating scenarios.

AbstractThe global elderly population rises, increasing dementia cases. Built environment impact on dementia health outcomes is known, forming the basis for evidence-based design studies. There's a need for a comprehensive assessment framework due to the complexity of interactions among Architectural Variables (AVs) and Health and Care Outcomes (HCOs). This paper proposes using Model-Based Systems Engineering (MBSE) to create such a framework. It collects data from 105 studies on 40 AVs, 36 HCOs, and 396 interactions. MBSE offers a holistic understanding, aiding healthcare facility design decisions.

Abstract:
AbstractIn the last few years, the growing need of highly reliable and time-effective strategies to perform preliminary design of complex systems has led industries to adopt the Model Based System Engineering (MBSE) approach. In MBSE, systems are split into multiple sub-systems and the relevant physical phenomena are described via analytical or numerical models. When a significant number of design variables are to be considered, a smart approach to reduce the number of analyses to perform would be to make use of the Global Sensitivity Analysis (GSA) to higlight those variables that have a more significant influence on the system output. Moreover, an even more significant reduction of computational cost to perform the GSA can be achieved if the complex system modelled via the MBSE approach is exported under the Functional Mock-Up Interface (FMI) norm. In this context, this paper proposes an original approach to address the study of two constructive solutions of an acceleration measuring device typically used on airbags for which the use of a new solution characterized by a porous material is compared with a classical one.

Abstract:
Abstract A data-centric approach is proposed to facilitate the design and analysis of challenging complex systems and address the problems of currently existing model-based systems engineering (MBSE) methodologies. More specifically, based on three core steps of current MBSE methodologies, a high-level data meta-model, depicting the semantic relationships of high-level data concepts, is first presented to guide the data modeling for systems engineering (SE). Next, with respect to the six high-level data concepts, the data elements are collected as the modeling primitives to construct static and/or executable models, which can also act as a common and consistent data dictionary for SE. Then, the mapping associations amongst core data elements are established to associate the model elements in different steps and achieve the requirement traceability matrix. Finally, the feasibility of the proposed approach is demonstrated with an illustrative example.

Abstract:
This study compares the reliability of estimation, productivity, and defect rate metrics for sprints driven by a specific instance of the agile approach (i.e., scrum) and an agile model-Bbased software engineering (MBSE) approach called the integrated Scrum Model-Based System Architecture Process (sMBSAP) when developing a software system. The quasi-experimental study conducted ten sprints using each approach. The approaches were then evaluated based on their effectiveness in helping the product development team estimate the backlog items that they could build during a time-boxed sprint and deliver more product backlog items (PBI) with fewer defects. The commitment reliability (CR) was calculated to compare the reliability of estimation with a measured average scrum-driven value of 0.81 versus a statistically different average sMBSAP-driven value of 0.94. Similarly, the average sprint velocity (SV) for the scrum-driven sprints was 26.8 versus 31.8 for the MBSAP-driven sprints. The average defect density (DD) for the scrum-driven sprints was 0.91, while that of the sMBSAP-driven sprints was 0.63. The average defect leakage (DL) for the scrum-driven sprints was 0.20, while that of the sMBSAP-driven sprints was 0.15. The t-test analysis concluded that the sMBSAP-driven sprints were associated with a statistically significant larger mean CR, SV, DD, and DL than that of the scrum-driven sprints. The overall results demonstrate formal quantitative benefits of an agile MBSE approach compared to an agile alone, thereby strengthening the case for considering agile MBSE methods within the software development community. Future work might include comparing agile and agile MBSE methods using alternative research designs and further software development objectives, techniques, and metrics.

Abstract:
Currently, the fundamental tenets of systems engineering are supported by a model-based approach to minimize risks and avoid design changes in late development stages. The models are used to formalize, analyze, design, optimize, and verify system development and artifacts, helping developers integrate engineering development across domains. Although model-based development is well established in specific domains, such as software, mechanical systems, and electrical systems, its role in integrated development from a system perspective is still a challenge for industry. The model-based systems engineering (MBSE) tool-chain is an emerging technique in the area of systems engineering and is expected to become a next-generation approach for supporting model integration across domains. This article presents a literature review to highlight the usage and state of the art to generally specify the current understanding of MBSE tool-chain concepts. Moreover, the results are used for identifying the usage, advantages, barriers, concerns, and trends of tool-chain development from an MBSE perspective.

Abstract:
AbstractModel-based systems engineering (MBSE) is well-known in gaining the control over the complexity of systems and the development processes, while agile is a project management methodology originally from software development that uses short development cycles to focus on continuous improvement in the development of a product or service. In this paper, we adopt the concept of agile into MBSE and then proposed the new approach - Munich Agile MBSE Concept (MAGIC). The highlights of the MAGIC approach can be concluded as 1) the requirements which have been defined in the first stage will be examined and traced at each following stages; 2) communication between every 2 stages always exists in order to have a close connection during each system development phase; 3) the idea of Industry 4.0 has been included and reflected to achieve automation and data exchange with manufacturing technologies; 4) the concept of IOT (Internet of Things) is also considered when it comes to the usage and service of the system to satisfy the customer's needs; 5) the whole spirit of agile is reflected as the iterative and incremental design and development

Abstract:
AbstractTo keep pace with growing system complexity, Digital Engineering (DE) Model Based Systems Engineering (MBSE) capabilities must be expanded. A digital thread based approach is required to holistically evaluate measures of effectiveness/performance for missions. This paper describes the approach taken to connect requirements, SysML‐based architecture, and analytical Modeling and Simulation (M&S) yielding an interdisciplinary digital thread supporting mission analysis. The analysis was conducted in support of a multi‐domain (land, air, sea, and space) multi‐platform mission to detect, track, and engage the enemy. The approach used commercially available tools, strategically connected to establish an Authoritative Source of Truth (ASOT) for each piece of data, and gain insights about the System of Systems (SoS) beyond that which the component models could provide on their own. The results of these efforts produced a multipurpose SoS MBSE toolset enabling semi‐automated trade study analysis, while more importantly serving as a basis from which to expand systems engineering activities during subsequent phases of the systems' lifecycle. This paper concludes by identifying further opportunities for MBSE research and development to expand the developed capability.

Abstract:
AbstractThe development of a new motor can be a high effort. In this paper, Model-based Systems Engineering (MBSE) is applied to model the second generation of an electronic compact actuator (ECA). This paper focuses on the traceability between model elements from previous product generations. By integrating the approach of the PGE - Product Generation Engineering in MBSE, developers can store more relevant information in the model; they can accomplish automatic calculations of derived factors and build models more efficiently in further product developments.

Abstract:
AbstractIndustry 4, the Internet of Things, and large‐scale system‐to‐system interactions are driving digital transformation in the industry. Model‐based systems engineering (MBSE) is one of the core paradigms behind this transformation. MBSE practices are widely applied to enterprise (including system of systems and mission) architectures, which become a crucial part of successful digital transformation. The core challenge today is not only how digital continuity can be maintained by connecting different layers of models (such as system models to system‐of‐systems models), but also how to perform detailed analysis and simulation at the enterprise level model. This paper studies Systems Modeling Language (SysML) as the standard language to model systems, Unified Architecture Framework (UAF) as the framework, Unified Architecture Framework Modeling Language (UAFML) as the language to model enterprise architectures, and proposes an approach for end‐to‐end co‐execution of the integrated enterprise model.

Abstract:
This paper presents an approach to the utilization of model-based systems engineering (MBSE) early in the system lifecycle, which focuses on early identification of desirable system characteristics to support mission engineering (ME). The paper relies on the definition of an analysis approach and the associated mapping of architectural products. The analysis strategy focuses on integration of the results of operational simulations and system synthesis models through tradespace visualization. The architectural mapping presents the association of Systems Modeling Language (SysML) products to the analysis strategy. The coordination of these elements is presented as a demonstration of the role that MBSE concepts can play in support of ME. The approach is demonstrated through a case study analysis of a conceptual mine warfare system conducting mine countermeasure operations.

Abstract:
AbstractThis paper describes a test framework for verification and validation (V&V) planning and execution using a model‐based system engineering (MBSE) approach that is suitable for large‐scale cyber‐physical systems. The test framework (TF) is defined using the systems modeling language (SysML) and an MBSE tool and describes and links to external test plans, test procedures, and other relevant test documents. This test framework approach includes the following considerations: level of abstraction of systems for testing, multiple types of testing across the development lifecycle, design vs. system V&V approaches, verification vs. validation, and the use of test patterns, instances, inheritance, and libraries. The libraries contain distinct types of tests to maximize model element reuse. An example is provided that illustrates the application of this V&V Test Framework (V&VTF) to a lubrication system. This method demonstrates that the proposed V&VTF is desirable as part of Systems Engineering metamorphosis to support an organization's digital transformation.

Abstract:
AbstractDeveloping autonomous functions for complex systems leads to high demands on the consideration of dependencies to external actors in the usage phase. In Model-Based Systems Engineering (MBSE), this can be achieved by modelling operational aspects. Operational aspects are model elements and their relationships to each other. In this contribution, modelling of operational aspects with a MBSE-approach will be demonstrated exemplary on a case study related to the development of a yacht with an autonomous docking assistant. Currently modelling operational aspects is not common in the civil sector.

Abstract:
Model-based systems engineering (MBSE) is a modeling approach used in industry to support the formalization, analysis, design, checking and verification of systems. In MBSE modeling, domain knowledge is the basis of the modeling. However, modeling does not happen overnight; it requires systematic training and a significant investment of resources. Unfortunately, many domain experts lack the expertise required for modeling, even though they know the domain well. The question arises about how to provide system modelers with domain knowledge at the right time to support the efficient completion of modeling. Since MBSE research that integrates AI is just beginning to take off, no public dataset is available. In this paper, aerospace SysML models are constructed based on spacecraft-related domain knowledge to form SysML model data. The validation rules are studied to validate the SysML model data, and combined with the concept of the recommended system, a recommendation method for the MBSE modeling process based on the knowledge and SysML model is proposed. A GLOVE language model is pre-trained by using domain knowledge and general knowledge; the model data are also used to fine-tune the GLOVE language model combined with the pre-training to recommend some domain development processes. The recommendation list is manually quality-verified and fed into the pre-training phase, while new requirement texts are continuously added in the fine-tuning phase, resulting in a more relevant and accurate recommendation list. Experiments show that the incremental recommender system can not only effectively recommend SysML models, but also improve the quality and efficiency of MBSE development.

Abstract:
One major challenge of today’s product development is to master the constantly increasing product complexity driven by the interactions between different disciplines, like mechanical, electrical and software engineering. An approach to master this complexity is function-oriented model-based systems engineering (MBSE). In order to guide the developer through the process of transferring requirements into a final product design, MBSE methods are essential. However, especially in mechanics, function-oriented product development is challenging, as functionality is largely determined by the physical effects that occur in the contacts of physical components. Currently, function-oriented MBSE methods enable either the modeling of contacts or of structures as part of physical components. To create seamless function-oriented mechanical system architectures, a holistic method for modeling contacts, structures and their dependencies is needed. Therefore, this paper presents an extension of the motego method to model structures, by which the seamless parametric modeling of function-oriented mechanical system architectures from requirements to the physical product is enabled.

Abstract:
Model-based Systems Engineering (MBSE) approaches are a step forward in the evolution of computer-aided engineering, and yet, they often incorporate deficiencies that may jeopardize their practical utility and usability, as well as the validity of the resulting models. We demonstrate how a domain-specific modeling approach can relieve some hurdles in adopting MBSE, and how it can be used in tandem with a general-purpose modeling approach to augment and introduce rigor to models. Specifically, we demonstrate the consequences of theoretical issues that were previously identified in Object Process Methodology and suggest an approach to solve them. We use a generalized case-study—derived from extensive process modeling in both academia and industry—to show that a domain-specific model can significantly relax the user’s modeling effort. This demonstration is based on two quantitative metrics: the number of representational elements and available modeling tactics. We discuss the contribution of our approach to model quality, particularly with respect to its rigor and communicability.

Abstract:
AbstractSince the last decade, the automotive industry has undergone a significant transformation, moving from traditional document‐based systems engineering to a more architecture‐focused and model‐based systems engineering (MBSE) approach. This shift is driven by the rapidly increasing complexity and the difficulties in managing system descriptions using conventional document‐based methods. The paper investigates how MBSE can support this transformation using an architecture framework developed at Continental. As a response, the authors propose an architecture‐centric Systems Engineering approach based on viewpoints. The focus on architecture‐centricity and using models enables a more efficient and effective way of analyzing, developing, and designing complex systems. The authors use an automotive example to demonstrate how this approach can be practically implemented within a development workflow. The article highlights the architecture‐centric model‐based systems engineering application through an in‐house architecture framework used at Continental.

Abstract:
AbstractIn order to assess AI/ML‐based autonomous systems in terms of safety, it is not sufficient to assess the system w.r.t. potential failures that could lead to hazards (e.g., as proposed by standards such as IEC 61508, ARP 4761, etc.). Also, functional weaknesses/insufficiencies of the used algorithms according to Safety Of The Intended Functionality (SOTIF) standard ISO 21448 must be considered. In this paper, we present an approach for the safety assessment of systems incorporating AI/ML models using a Model‐based Systems Engineering (MBSE) and a Model‐based Safety Assurance (MBSA) approach. Therefore, we introduce with Component Fault and Deficiency Trees (CFDTs) an extension of the model‐based Component Fault Tree (CFT) methodology. Thereby, we are able to describe cause‐effect relationships between individual failures and functional insufficiencies as well as system hazards and assess if all risks are mitigated. In this paper, we apply our approach to an industrial case study of a self‐driving toy vehicle (the PANORover) and present our lessons learnt.

Abstract:
AbstractDue to an expanding number of mechatronic functionalities in modern technical products, the proportion of software and electronic components is also increasing. As a result, the products are developed by different engineering domains in complex development processes. To handle the growing complexity, Systems Engineering (SE) is increasingly important for development organizations of enterprises. System Engineering (SE) is understood as an approach to network the individual engineering domains and shall lead to a collaborative development of complex systems. Model-Based System Engineering (MBSE) expands SE by using common models and software tools to describe und visualize the systems. However, MBSE is not widely established in enterprises today. On the one hand, the introduction requires a distinct and consistent system understanding and collaborative way of working. On the other hand, the application of the existing tools requires extensive tool competencies due to many possible functions and features. Therefore, this paper presents a concept and a software based tool for a lean implementation of SE/MBSE to support the collaborative development of complex technical systems in small and medium-sized enterprieses.

Abstract:
The rapid progress of the Internet of Things (IoT) has continued to offer humanity numerous benefits, including many security and safety-critical applications. However, unlocking the full potential of IoT applications, especially in high-consequence domains, requires the assurance that IoT devices will not constitute risk hazards to the users or the environment. To design safe, secure, and reliable IoT systems, numerous frameworks have been proposed to analyse the safety and security, among other properties. This paper reviews some of the prominent classical and model-based system engineering (MBSE) approaches for IoT systems’ safety and security analysis. The review established that most analysis frameworks are based on classical manual approaches, which independently evaluate the two properties. The manual frameworks tend to inherit the natural limitations of informal system modelling, such as human error, a cumbersome processes, time consumption, and a lack of support for reusability. Model-based approaches have been incorporated into the safety and security analysis process to simplify the analysis process and improve the system design’s efficiency and manageability. Conversely, the existing MBSE safety and security analysis approaches in the IoT environment are still in their infancy. The limited number of proposed MBSE approaches have only considered limited and simple scenarios, which are yet to adequately evaluate the complex interactions between the two properties in the IoT domain. The findings of this survey are that the existing methods have not adequately addressed the analysis of safety/security interdependencies, detailed cyber security quantification analysis, and the unified treatment of safety and security properties. The existing classical and MBSE frameworks’ limitations obviously create gaps for a meaningful assessment of IoT dependability. To address some of the gaps, we proposed a possible research direction for developing a novel MBSE approach for the IoT domain’s safety and security coanalysis framework.

Abstract:
AbstractThis paper provides a brief executive level description of Model Based Systems Engineering, (MBSE). It introduces the seven abstract core engineering steps that can be used to describe the engineering process and make the process tailorable. A representative set of tools is described that can span the engineering work.The MBSE process, with a tool set is described, as a means to automate the search of the application solution space for feasible or near optimal systems solutions. The approach applies to distributed and real‐time systems. A by‐product of the approach is an automated ability to reuse systems specifications and systems designs.A simple example is provided to show how the optimization works. It shows how modeling and automation augment inspired engineering but do not substitute for it. Substantial work is needed in information standards for systems, tools integration, and search procedures.

Abstract:
AbstractTo 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.

Abstract:
AbstractCurrent automotive Industry is facing numerous challenges. Business model is transitioning from ownership to shared mobility. Mobility of the future is becoming smarter, safer, more secured and connected. Distributed interconnected automotive systems will deliver added‐value mobility services. In the meantime, industrial standards require description of systems engineering practices as well as the practices justification. Automotive SPICE (ASPICE), a standard of software development best practices for automotive industry, for example, was one of the first to support the development of system and software now include hardware and cybersecurity. Traditional systems engineering development approaches are not any more appropriate. The current automotive system complexity requires new approaches like Model‐Based Systems Engineering (MBSE), using modeling and simulation. To address compliance to industry standards, traditional quality approaches consisting of or defining a quality system with a set of processes (e.g. Requirement elicitation process, documentation process…) are no more sufficient. Addressing these challenges require a digital transformation with two pillars. The first pillar is an MBSE methodology such as Cyber MagicGrid (Dassault Systèmes MBSE method) to define a set of best practices to develop a system. The second pillar is a quality management system that relies on the MBSE methodology rather than on a set of enterprise processes to address compliance with standards. Benefits of this approach is in acceleration of the digital enterprise transformation which is achieved by capitalizing the know‐how and considering the industry standards constraints.

Abstract:
To reduce the environmental impact of aviation, aircraft manufacturers develop novel aircraft configurations and investigate advanced systems technologies. These new technologies are complex and characterized by electrical or hybrid-electric propulsion systems. Ensuring that these complex architectures are safe is paramount to enabling the certification and entry into service of new aircraft concepts. Emerging techniques in systems architecting, such as using model-based systems engineering (MBSE), help deal with such complexity. However, MBSE techniques are currently not integrated with the overall aircraft conceptual design, using automated multidisciplinary design analysis and optimization (MDAO) techniques. Current MDAO frameworks do not incorporate the various aspects of system safety assessment. The industry is increasingly interested in Model-Based Safety Assessment (MBSA) to improve the safety assessment process and give the safety engineer detailed insight into the failure characteristics of system components. This paper presents a comprehensive framework to introduce various aspects of safety assessment in conceptual design and MDAO, also considering downstream compatibility of the system architecting and safety assessment process. The presented methodology includes specific elements of the SAE ARP4761 safety assessment process and adapts them to the systems architecting process in conceptual design. The proposed framework also introduces a novel safety-based filtering approach for large system architecture design spaces. The framework’s effectiveness is illustrated with examples from applications in recent collaborative research projects with industry and academia. The work presented in this paper contributes to increasing maturity in conceptual design studies and enables more innovation by opening the design space while considering safety upfront.

Abstract:
Moscow Institute of Physics and Technology (National Research University) The paper advocates the need to move from separate stages of the product life cycle (LC; R&D, production, operation) to a single project implemented in a new paradigm of system design based on software and methodological tools of model-based systems engineering (MBSE). Currently available in Russia foreign software (SW) and methodological MBSE tools for the design and development (D&D) of systems (including space instruments) are expensive and complex. This paper formulates and considers the question: «Is it possible to reduce the cost and simplify the use of software and methodological MBSE tools by means that are available to a wide audience of users?». To answer this question, the authors analyzed SysML, QFD method, HoQ method, and the SW for their application. As the result of literature review, it is shown that in the leading countries, the relevance of implementing these tools in the design and development of hardware and software systems is increasing. For the use of SysML, QFD, HoQ by a wide audience of potential users from Russian Federation were defined software tools. 13 disadvantages that prevent the application of SysML, QFD and HoQ, as well as SW for their use were identified. In order to overcome the identified disadvantages, was developed SW and methodological MBSE tool based on modernization, specification and synthesis of SysML, QFD, HoQ and SW for their application. The developed MBSE SW and methodological tool allows for a wide audience of users to D&D systems in accordance with MBSE approach (QFD, HoQ, SysML), to identify critical requirements of different development elements, to develop automatically (in a few hours instead of several days) and update SysML models of requirements, to reduce labor costs for the implementation of the D&D LC stages of future analog products by 5-10%. As a result of validation of SysML models, it is proved that their repeated use reduces the planning time of the LC stages of analog products by up to 60%, increases the compliance of the reporting documentation of the LC stages with the requirements of regulatory and technical documents by 10%.

Abstract:
This paper shows how a methodical development and configuration of modular product family concepts and their effects on economic targets can be implemented in SysML. For this purpose, different sources of inconsistency between different methodical tools are highlighted and the need for research is shown. As a solution approach, a methodical framework is presented, which can be used to implement product development methods for the developing of modular product family modeling by means of Model-Based Systems Engineering (MBSE) in the modeling language SysML. By applying the framework, it is shown on the one hand how a product family of vacuum cleaner robots as a simple example can be modularized in a methodical, model-based manner. On the other hand, a configuration system and an impact model of modular product families are connected with the system model and applied to a product family of laser systems as an industrial use case. This made it clear that the framework can be used to model various methodical topics of product family modeling in a consistent manner, to enable higher-level analyses with the use of MBSE tools. This can reduce errors, decrease effort and increase traceability across different methodical tools.

Abstract:
Some authors suggest that transitioning requirements engineering from the traditional statements in natural language with shall clauses to model-based requirements within a Model-Based Systems Engineering (MBSE) environment could improve communication, requirements traceability, and system decomposition, among others. Requirement elements in the Systems Modeling Language (SysML) fail to fulfill this objective, as they are really a textual requirement in natural language as a model element. Current efforts to directly leverage behavioral and structural models of the system lack an overarching theoretical framework with which to assess the adequacy of how those models are used to capture requirements. This paper presents an approach to construct true model-based requirements in SysML. The presented approach leverages some of SysML’s behavioral and structural models and diagrams, with specific construction rules derived from Wymore’s mathematical framework for MBSE and taxonomies of requirements and interfaces. The central proposition of the approach is that every requirement can be modeled as an input/output transformation. Examples are used to show how attributes traditionally thought of as non-functional requirements can be captured, with higher precision, as functional transformations.

Abstract:
AbstractModel‐Based Systems Engineering (MBSE) has been utilized in practice to design and behavioral modeling cyber‐physical systems. The Vee model helps frame MBSE's lifecycle approach, with system verification a vital aspect of the qualification process. However, popular modeling language tools in MBSE, such as Systems Modeling Language (SysML), are incapable of formally verifying these systems. Model checking allows for the development of formal system models similar in abstraction to SysML models for automatically checking if these formal models satisfy formal specifications. We propose an approach to translate behavioral diagrams in SysML, such as state‐machine diagrams, to the popular symbolic model checker NuSMV for formal verification. As a case study, we apply this process to autonomous multi‐differential drive robots (DDR). Subsequently, the NuSMV model is verified against some formal operational specifications obtained from the requirements diagram of the DDR. This system verification approach can help System Engineers identify design flaws or incorrect modeling or specifications that could be missed during the design phase through the results of the model checking process.

Abstract:
This paper introduces a model-driven control realization, which is based on the systems engineering concepts of the model-driven architecture (MDA)/model-based systems engineering (MBSE) approach combined with the real-time UML/SysML, extended/unscented Kalman filter (EKF/UKF) algorithms, and hybrid automata, in order to conveniently deploy controllers of autonomous underwater vehicles (AUVs). This model also creates a real-time communication pattern, which can permit the designed components to be customizable and reusable in new application developments of different AUV types. The paper brings out stepwise adapted AUV dynamics for control that are then combined with the specialization of MDA/MBSE features as follows: the computation independent model (CIM) is defined by the specification of the use-case model together with hybrid automata to gather the requirement analysis for control; the platform-independent model (PIM) is then designed by specializing the real-time UML/SysML’s features including main control capsules that depict structures and behaviors of controllers in detail; and the detailed PIM is subsequently converted into the platform-specific model (PSM) by object-oriented platforms to rapidly implement the AUV controller. Based on this proposed model, a horizontal planar trajectory-tracking controller was deployed and tested that permits a miniature AUV possessing a torpedo shape to reach and follow the desired horizontal planar trajectory.
