Within the framework of model-based system engineering (MBSE), models are developed to support system requirements, design, analysis, and test activities from design through sustainment to end-of-life. Traditional methods do not effectively integrate reliability, availability and maintainability (RAM) analyses into the model architecture, leading to a disconnect between design, systems and reliability engineering efforts. The solution demonstrated in this study facilitates RAM performance predictions against mission needs for a Navy frigate, consisting of several critical systems responsible for a wide range of missions. By linking RAM data with the platform's architectural design in an MBSE environment, engineers were able to analyze platform and mission RAM predicted performance against requirements. This study demonstrated that Cameo system modeler provides an adequate analysis tool suite and the capabilities to enable a comprehensive RAM analysis. The resulting data provided stakeholders with insight into the systems, or subsystems, that were negatively impacting the platform's RAM performance and the ability to proactively mitigate these concerns. Ultimately, the consolidation of systems and reliability engineering into one integrated digital environment improved understanding and collaboration across the various engineering facets, while providing a data-driven assessment of the overall platform's mission effectiveness.

In the context of the revolution of energy production and consumption, the urgency of building a multi-energy coupling system is becoming more and more obvious. Compared with the traditional energy system, the construction of a multi-energy coupling system has more needs. With the development of new energy and the complexity and scale of the energy system, the multi-energy coupling system can better meet the needs of the current energy system. To this end, model-based system engineering (MBSE) is introduced in the construction of multienergy coupling systems to adjust adjustable loads and improve energy efficiency. In the process of planning the multi-energy coupling system, the introduction of the above technical means is helpful to solve some problems existing in the planning and application of the multi-energy coupling system. © 2024 IEEE.

model-based Test engineering (MBTE) is an approach to how test can deliver new, unique, and increased value to organizations and programs in the Digital engineering landscape. Using standards such as SysML[1] and ATML[2], a common language (style guide) and set of workflows are being defined that bridge the worlds of model-based system engineering, Design engineering, and Test. There are many challenges that exist today that increase the costs and schedules of programs. These include requirements sufficiency, tracking requirements across the program life cycle, knowledge capture, lack of "authoritative sources of truth (ASOT)," TPS development and maintenance, and ATE maintenance and obsolescence. This paper provides an overview of MBTE, what needs to be described in the SysML domain and how that enables high value such as keeping the SysML models as the ASOT for test and automating the downstream ATE workflows such as TPS generation. MBTE enables systems engineering, Design engineering, and Test to have a common language to achieve greater understanding and agreement as to what needs to be tested and improve decision making. With so much investment being put into models, extracting the most value out of those models is imperative. MBTE is an approach that is being built to extract that value across the program life cycle.

Industries still have problems managing and organizing control software variants for different machine processes in Cyber-Physical Production systems (CPPSs). They still rely mostly on clone-and-own approaches to create new control software variants when introducing new process variability in reaction to customers' requirements. This approach not only results in code duplication but over time particularly makes it more difficult to maintain and evolve the software. Due to a lack of modularization, this approach also often results in unnecessary code in delivered software, locked by parameters, which can have a further negative effect on maintenance. In this paper, we discuss modularization approaches to organize control software in CPPSs. Specifically, for IEC 61499-based control software, we propose the combination of explicit variants described in 150% modules, standardized interfaces, and separation of concerns. We discuss how our approach could help industry to decrease the effort for new projects and at the same time get a better overview of the product and process variability of their CPPSs.

Autonomous vehicles handle complicated tasks that may lead to harm when performed incorrectly. These harms, in particular when caused by system faults, may be avoided by the deployment of safety architectural patterns, such as the Heterogeneous Duplex pattern. Our goal is to provide safety engineers with computer-aided support for synthesizing architectures with safety architecture patterns. To this end, we build on our previous work in which we proposed a model-based system engineering plugin to enable the model-driven approach using safety architecture patterns. This article proposes a toolchain for synthesizing the structure and switching logic of safety architectures, as well as for validating them through simulation-based fault-injection. We validate our toolchain using an industrial use-case for autonomous driving systems, namely, a Highway Pilot system. © 2023, The Author(s), under exclusive licence to Springer Nature Singapore Pte Ltd.

In order to deal with the increasing complexity of nowadays systems, model-based system engineering (MBSE) promotes the use of models all along the engineering phases. In this scenario, systems are often represented by a set of models, conforming to different modeling languages and built with different tools. This multiplicity and heterogeneity are challenging when models evolve as they may easily become inconsistent. This is even more crucial when we deal with security requirements. Indeed, being a critical property of systems, security has been integrated in MBSE so that it can be dealt with since the early phases of the project (in what is called "security-by-design"). Consequently, it needs to be taken into account as well when the system evolves in order to avoid potential security issues. In order to tackle this problem, we propose here to leverage on the model federation paradigm, which promotes the reification of the dependencies between heterogeneous models. Concretely, we propose the creation of a security model federation. In this federation, security related dependencies between the models representing a system are reified and equipped with security rules that can be (re)evaluated upon evolution scenarios in order to determine whether a given change impacts security. We provide an initial methodology for building such a federation and demonstrate the feasibility of the approach with a prototype implementation.

Product iterative design contributes to product performance, stakeholder satisfaction, etc., and is one of the major competencies of complex equipment manufacturing companies. Nevertheless, a large quantity of knowledge is generated during the whole life cycle of complex products, and it is crucial to use this knowledge to implement iterative product design. The application of knowledge in the product design stage is mostly based on knowledge pushing from static knowledge base, which is prone to problems such as inefficient knowledge management and insufficient expression of semantic relationships, and does not combine with product iterative design scenarios. To this end, this paper proposes an iterative design knowledge pushing method combining SysML(system modeling Language) and knowledge graphs. Firstly, the method constructs a SysML-based iterative product design system model for supporting the determination of iterative design intention scenarios. Secondly, the knowledge graph technology is used to unify the management and representation of product iterative design knowledge. Thirdly, the knowledge graph for the iterative design process is constructed oriented to the iterative feedback requirements based on FBS(Function-Behavior-Structure) and knowledge complexity calculation to determine the KDA(Knowledge Demand Anchor). Finally, based on the determined KDA, the design knowledge is pushed with the help of TransR(Translate-R) and random walk algorithms. The proposed method is verified by an illustrated case. © 2023 IEEE.

Under the background of the integration and development of next-generation information technology and the manufacturing industry, production equipment has evolved into Cyber-Physical system (CPS), which seamlessly combine embedded computing, network communication, and high-performance control. In this context, the information model of production equipment has gradually become a pivotal aspect supporting the visualization of the physical operation status of production equipment, optimizing decision-making in the digital realm, and enabling communication and interaction mapping in the cyber-physical space. based on the model-based systems engineering (MBSE) principle, a unified information model for the whole manufacturing process of production equipment is proposed to solve the problems of diverse information types, diverse expression forms and complex model heterogeneity in the field of production equipment information modeling. From the perspectives of communication, knowledge, and geometry, the management activities of production equipment are analyzed, function modules are assigned, and information elements are defined. Consequently, a holistic information model for production equipment is formulated to support the integration of multidimensional models and realize the optimization and control of heterogeneous production equipment, which providing valuable reference for developers and practitioners of the production equipment information model. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

The development of an aircraft industrial system is a complex process which faces the challenge of digital discontinuity in multidisciplinary engineering due to various interfaces between different digital tools, leading to extra development time and costs. This paper proposes an ontology-based system, aiming at functionality integration and design process automation, by models for Manufacturing methodology principles. A tool-agnostic modelling, simulation and validation platform with Discrete Event Simulation and 3D simulation is enabled and demonstrated in a real case study. An ontology layer collecting the domain knowledge enables integration of the proposed system, accelerating the design process and enhancing design quality.

An efficient spatial high-utility occupancy frequent item mining algorithm for mission system integration architecture design using the MBSE method

Future airspace operations require the integration of various types of comprehensive combat forces, which belong to systematic combat. At present, integrated systems are oriented to the single platform system. systematic integrated mission system is more complex, which not only considers the utility and efficiency of the single platform, but also considers multi-platform collaboration. Therefore, it is more complicated and difficult to obtain requirements and design mission system architecture, which requires multiple design scenarios. Due to the large amount of data of the scenarios model, the efficiency of manual analysis is too low, so data mining method is needed to analyze the scenarios data. However, traditional data mining methods cannot simultaneously mine item location information and utility occupancy. This paper proposes an algorithm: SHUO-FI, to mine utility occupancy threshold under specified distance constraints and a new pruning strategy based on support and maximum utility occupancy constraints. Compared with other algorithms, it is found that the proposed algorithm has higher efficiency. Since the algorithm considers the location, weight, profit, utility and other parameters of the project, it can be better applied in the field of forward design MBSE than the previous algorithm. Finally, the algorithm is applied to the actual coordination of manned and unmanned aircraft model. By data mining the utility, profit and real-time position of each operational unit at each time, the optimal operational function scheduling mode under the same operational mission can be obtained. © 2021, Shanghai Jiao Tong University.
