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.

PLM and Design Automation (DA) are two interdependent and necessary approaches to increase the performance and efficiency of product development processes. Often, DA systems' usability suffers due to a lack of integration in industrial business environments stemming from the independent consideration of PLM and DA. This article proposes a methodological and modeling framework for developing and deploying DA solutions within a global PLM approach. This framework supports the identification of DA potentials and the definition of the DA task building blocks to support DA task formalization by practitioners. The aim is to make the specification and development of DA solutions more efficient and aligned with the business requirements and with the existing digital environments. This framework combines the usage of two standardized modeling languages to make the captured knowledge re-usable across heterogeneous PLM and DA applications. An industrial case study demonstrating the applicability of the framework is introduced and discussed.

The process of writing requirements specifications, designing, developing, and verifying high precision pointing space mechanisms currently relies on a domain specific simulation-centric approach extensively applied since the very early stages of a project. Space mechanisms requirements specifications often are driven by domain specific features, with many significant uncertainties, and requirements conflicts due to the lack of a holistic perspective. Specific domain simulations are run repeatedly under the given conditions. Such a process is highly inefficient for a company that either writes a requirements specification (manages subcontractors) or designs space mechanisms itself. A general purpose modeling method is proposed to accompany domain specific simulation methods. The resulting framework is proposed to be applied to high precision mechanisms of scientific space missions. Survey of the stakeholders and comparison of methodologies during the conceptual identification of the framework foster an object oriented model-based system engineering methodology and the general purpose SysML modeling languages as the basis for the general purpose modeling part of the framework. The domain specific simulation part is based on the implementation of existing tools under the overall supervision of the general purpose models.

SysML language, proposed by OMG, is a commonly accepted standard to model and study systemsof-systems (SoS). It provides the means to depict SoS components and their behavior in a multi-layer fashion and explore alterative architectures for their design. To validate SysML models in terms of performance criteria, simulation is usually the preferred method employed. To this end, different SysML diagrams are utilized, while numerous simulation methodologies and tools are employed. There are many efforts targeting simulation code generation from SysML models. model-based system engineering concepts are adopted in most of them to generate simulation models from SysML models. Nevertheless, this process is not standardized, although most of current approaches tend to follow the same steps, even if they employ different tools. The scope of this paper is to provide a comprehensive understanding of the similarities and differences of existing approaches and identify current challenges in fully automating SysML models simulation process.

model-based system engineering is increasingly adopted. However it is centred on the notion of model while the industry is still strongly document-based. In order to enable a smooth evolution between those paradigms, the interplay between documents and models need to be managed, especially models can be used to efficiently derive up-to-date documents matching standard templates from initial requirements to final certification. The purpose of this paper is to review and to assess current strategies to manage model for document generators in order to meet industrial requirements like document complexity, document/model scalability, quick generation time, maintainability and evolvability of document templates. After exploring different generation strategies, our work focuses on toolchains based on the Eclipse modelling Framework and compares a few shortlisted libraries in the light of our requirements and using document derived from industry cases.

The increasing use of software in Embedded Real Time systems (ERTS) has allowed the application of software engineering methods and techniques in their development. In this regard, Service-Oriented Computing (SOC) has previously been used to reduce the development complexity of ERTS. However, the concepts of SOC are mostly used at the implementation level without any focus on system design. To fill this gap, the author has previously developed a meta-model for service-oriented development of ERTS. Although the proposed meta-model allows the high-level modeling of ERTS in terms of service-oriented concepts, it covers only the structural requirements. Therefore, the meta-model is further extended in this paper to include the behavior modeling of the system. The effectiveness of the proposed mechanism is demonstrated with the help of Traffic Light Controller and Arbiter case studies. Following the model based system engineering process, the high-level models can be transformed into the low-level models.

We combine Object-Process Methodology (OPM) with Design Structure Matrix (DSM) and its Multi Domain Matrix (MDM) extension to capitalize on the potential synergies of these two approaches to model-based systems engineering. OPM can provide a very detailed system model, but it is limited in examining the system as a whole, especially when the system is large and complex. DSM, which provides a matrix representation of the system, lists all the elements and shows relations between model elements. This matrix is amenable to matrix manipulation like clustering and partitioning, enabling the evaluation of relations among model elements. We follow a methodical five-step approach for applying DSM to analyze and improve complex OPM system models. Dedicated preprocessing algorithms have been developed and applied to eliminate states from objects and flatten the hierarchical OPM model while maintaining its semantics. The resulting DSMs and DSM variations of an OPM model are then analyzed, this can be achieved by domain experts who can get ideas or suggestions to improve the model based on quantitative metrics. After examining outcomes of clustering or partitioning algorithms on the DSM, the modularity of the model can be improved, yielding possible gains for the system under development.

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.

The paper proposes a novel computer-aided model-based system engineering process for Smart Gird applications. The process is supported by the SysGrid tool that plays the roles of system configurator and device configurator. The design process starts with single line diagrams which are automatically transformed to executable function block specifications. The process is based on the Smart Grid control architecture that is a heterogeneous network of controllers communicating in a peer to peer manner. This "artificial nervous system" of the Smart Grid will be capable of self-healing and dynamic adaptation to renewable generation and ever-changing loads. The tool supports system-level design of automation logic in the form of function block networks with compliancy to IEC 61499. The capabilities of SysGrid are demonstrated through the process of designing a distributed protection application.

Safety issues are one of the core attributes of the projects of the New Space economy such as SpaceShipTwo and New Shepard. While these projects are on their way to shifting the paradigms in space tourism and transportation, the question of tourist safety remains in the cornerstone for a successful operations. One of the important questions we encounter when we start the development of complex systems such as the suborbital transportation and space tourism systems is: what are the concepts available and how can these concepts be represented using strictly defined ontology and model semantics? And finally – how this model-based information would support the system architect in keeping track of safety aspects? In this work we present a model-based concept framework that aims to address this issue. First a concept framework methodology is presented, after which we demonstrate its applicability to suborbital human spaceflight missions–SpaceShipTwo and New Shepard. The analytical conceptual difference between these concepts is demonstrated. The proposed framework includes: the information about the stakeholders and their needs;the solution-neutral environment (the problem statement) in which we formulate the functional intent;the solution-specific environment (solution statement) in which we see the possible solutions;the integrated concept revealed by means of the decomposition of such solution into internal elements and functions;and the concept of operations. Each one of these entries of the concept framework has a counterpart represented in conceptual modeling languages, such as Object-Process Methodology (OPM) or the system modeling Language (SysML). Such a model-based concept framework encodes the core information required to define a suborbital tourism concept and represent it in a digital environment. We believe this will become a powerful tool to support the makers of architectural decisions that lead to concept and eventually to architecture, and that provides
