The failure of protective systems can be catastrophic, and has its origin in management. Yet, most engineering works regarding protective systems focus on their physical components. Historically, protective systems have relied on a document-based approach, which implies handling several disjointed artifacts that are expensive to maintain and have a high potential for inconsistency and obsolescence. We present a framework that embeds management and governance in protective systems and harmonizes regulations, theories, and inconsistent industry guidelines. It pioneers the modeling of protective systems according to the tenors of model-based systems engineering (MBSE), which significantly reduces the pitfalls of its document-based counterpart. It provides a realistic approach to manage multiple aspects of change, and offers traceability, simulation, and visualization capabilities. First, we sketched a conceptual model that encompasses the physical components, management system, policy, laws and regulation, stakeholders and lifecycle, and stresses the importance of understanding the interactions among elements and their dynamic nature. Then, we used it as a baseline to develop the structure and behavior of our computerized model in SysML. Our MBSE framework advances the state of the art in safety-critical protective systems by integrating management and governance, and offering further capabilities inherent to the MBSE approach. It is suitable for combined design, operation, and regulation; it reduces the cost of maintenance of its artifacts; and it offers tools for simulation, impact analysis, and management of change. It supports shared governance and mitigates information asymmetry. Potential users include both enterprises and regulators from the chemical process safety industry and the energy sector, and any other agents invested in the design and management of protective systems. The model of protective systems developed in this research conforms to the standards i

This paper formulates a model-based technology roadmapping architecture as an integrated framework to model and simulate decision-making problems in technology strategy settings. A model-based roadmapping framework is proposed as a complementary approach to traditional workshop-based roadmapping approaches. The framework structures a technology roadmap in data analytics, knowledge management, continuous improvement, and visualization elements. All elements are interrelated and managed through a systematic model structure, a relational database and distributed version control. The paper demonstrates the approach on a case study of orbital launch vehicles, and provides a side by side comparison of the approach to traditional workshop-based roadmapping methods. The approach presented in this paper allows roadmapping teams to deliver fact-based roadmaps while ensuring information consistency and holistic inclusion of all relevant product, technology, and market perspectives.

Traceability allows product developers to know more about the logical relationships in model-based systems engineering. Despite the known advantages, traceability is still not established as a standard in product development. High amount of necessary work force for traceability creation counts as one of the major obstacles against traceability. In this work, we investigate the applicability of transitivity rule to automate the creation of traceability. The conducted experiment shows, that automated traceability creation with transitivity rule is possible, however, wrong tracelinks are still inevitable.

Humanity is currently facing an unprecedented chronic disease burden. Healthcare needs have significantly shifted from treating acute to treating chronic conditions. Chronic diseases tend to involve multiple factors with complex interactions between them evidenced by the continually growing medical knowledge base. The health profession requires the ability to manage this rapidly deepening knowledge base to assimilate the lessons from research and clinical care experience by systematically capturing, assessing and translating it into the highest level of reliable care. A more systems approach to practicing medicine exists and is referred to as functional medicine. It takes into account the many subsystems in the human body and their many interactions. Although the science behind treating the patient as a system exists, the application of systems tools and techniques have not been utilized. It is only natural to begin to formalize the systems thinking using the established tools from the systems engineering field. Specifically, this paper is the first to contribute to the need for systems tools in the practice of clinical medicine and includes an example application of model-based systems engineering to clinical medicine.

This paper presents objectives for permeable electric/electronics product data management for mechatronic products in consideration of model-based systems engineering from the early product development phase till a lifecycle management. Idiosyncrasies of mechatronic products, requirements engineering, model-based systems engineering, artifact-orientation, and interconnections of artifacts are evaluated and postulate objectives, how artifacts have to be designed in order to support the linkage of model-based systems engineering and product data management (PDM). The objectives, derived from the different theories and requirements to foster permeable PDM, are: i) Identify all existing norms for the development of mechanical, electronic, and software aspects and elaborate how information artifacts have to be defined. ii) (Textual) Requirements have to be technically feasible to be linked to information artifacts and system models already in the early development phase. iii) System models have to be aligned to information artifacts from the models' creation onwards and standardization in exchange formats has to be ensured. iv) Information artifacts with own lifecycles shall alleviate PDM in the early product development phase. v) Interconnections shall ameliorate associativity through capturing process information between single artifacts. A first concept is presented, visualizing the aforementioned objectives and their contribution in the early development process of mechatronic products, how a permeable PDM might be achieved.

By taking a model-based systems engineering (MBSE) approach, a framework can be developed for long-term exploration of a complex adaptive system in multiple contexts. The framework uses MBSE tools to define the complex system architecture and modern internet state transfer and structured data format standards to integrate natural language descriptions, datasets, and models. These can constitute a knowledge architecture that can be used as a long-term research tool. The long-term goal is a framework that captures conceptual models of the complex system, data sets and relationships, dynamic models and simulations, and decision analytics within a common environment. This paper presents a scenario in which we evaluate links between transformations of complex natural gas systems and analyze political intervention into the Russian-European natural gas markets. In this example, we specifically examine geographical, physical (cross-border infrastructure), and commercial value streams through the prism of network analyses. This is one context of a more general model of international gas relationships and flows at multiple levels. The resulting framework provides insight into dynamic behaviors at multiple levels of the system, such as the emergence of infrastructure network and intricate relationships of strong corporate ties and knowledge networks, along with possible strategies for political and economic intervention. The primary goal of an MBSE approach is to capture interrelationships in the complex system at varying levels of abstraction, which enables a common reference for diverse models and datasets.

The present paper focuses on the model-based systems engineering of a battery electric vehicle called FReDy with intelligent chassis systems. This research vehicle is equipped with two electric drives on the rear axle that are positioned close to the wheels. FReDy combines electric traction with an intelligent chassis consisting of four independent active wheel modules and is a fully active electric vehicle. Using a hierarchically structured vehicle management the research vehicle FReDy enables driving that is optimized with regard as well to energy consumption as to driving dynamics and driving safety. Conception and realization of the vehicle are performed by means of a structured procedure in a model-based, hierarchical approach of systems engineering.

model-based systems engineering approach for the development of the science processing and operations center of the NASA OSIRIS-REx asteroid sample return mission

The Origins Spectral Interpretation Resource Identification Security Regolith Explorer (OSIRIS-REx) asteroid sample return mission, which is planned for launch in 2016, will study and return a sample from asteroid Bennu to Earth for further detailed analysis. This mission is unique in that little information about Bennu, including the gravity field, shape model, and thermal environment, is well known at this time. This information will instead be determined via a thorough close-proximity operations phase that will fully characterize and analyze the asteroid prior to retrieving the sample, requiring a complex ground system architecture in order to provide scientists the necessary information to make key decisions regarding sample collection. Importantly, the OSIRIS-REx Science Processing and Operations Center (SPOC) is at the heart of the process to characterize the asteroid and collect the sample, as its high level functions include the data processing necessary to fully analyze the information from the spacecraft and the generation of instrument observation sequences to collect the necessary data. These factors necessitate a strong systems engineering focus across the project. The SPOC team has chosen to tackle this problem by utilizing a model-based systems engineering (MBSE) approach to facilitate the development of the OSIRIS-REx ground system, and more specifically, the SPOC. MBSE is a relatively new approach that formally applies modeling to support system requirements, design, analysis, and verification and validation activities, and only recently been used in the development of the ground system of a space mission. As such, this approach has been lauded in key mission reviews as a significant strength of the project, especially for its ability to provide a consistent approach for the entire ground systems team. Importantly, the MBSE approach has provided many benefits to the SPOC systems engineering team. In particular, the MBSE approach has been utilized to

As systems become more complex, the systems engineering community must find new and more efficient ways of dealing with complexity throughout the system's lifecycle. model-based systems engineering (MBSE) has proven to be effective at managing complexity through the development of systems in a virtual environment. Several languages have been developed in the spirit of MBSE;however, these languages often do not include the full spectrum of information needed for holistic system solutions. The Lifecycle modeling Language (LML) has been developed to provide extensible language that contains both visualization models and an ontology. When LML is coupled with the systems modeling Language (SysML), the result is a modeling constructs that better supports systems engineering processes across the entire spectrum of lifecycle concerns. This coupling will not only be beneficial today, but could serve as a catalyst for a future MBSE environment.

This paper describes a process developed to utilize information within an ontology, a form of a component model library, for design space refinement in conceptual design through the use of an Interactive Reconfigurable Matrix of Alternatives (IRMA). An ontological approach is proposed, as it enhances the capabilities of component model libraries that are already being constructed for use in model-based systems engineering (MBSE) programs. By defining a common vocabulary across multiple design domains, an ontology is capable of driving information consistency and reducing errors that occur due to misinterpretation of common vernacular. Within an ontology, a functional decomposition of any complex system can be represented as a hierarchy of "classes", where a class defines any concept within a given domain. The functions that each system must perform, along with the system components that achieve each function and the design alternatives for each component, are related to the system as properties of the system. This functional decomposition structure of the ontology may be identical to the decomposition that is used in an IRMA, which can use information exported from the ontology to perform design space refinement during conceptual design. The result of this study is a process which is capable of extracting information from an ontology, organizing it, and importing it directly to an IRMA which is fully functional and ready to be used. Such a process becomes a powerful capability when similar systems are designed, as the process can be reused, serving as a starting point for concept selection in conceptual design, resulting in reductions in both development time and cost.
