“…Saunders shows that MBSE is a promising approach to reduce the defects density in requirements specifications [5]. Several works and research showed the benefits (demonstrated and assumed) of holistic modeling frameworks and MBSE under stakeholders objectives ambiguity [9], to approach the design of modern and complex systems [18] [19] [20] [21], to evaluate small satellite architecture and mission definitions [23].…”

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.

“…Since these initial innovations, MBSE at JPL has flourished in a number of projects. In particular, the Ops Revitalization Task [3], the Europa Study [4] and the Integrated Model-Centric Engineering effort [5] have been crucial drivers for the development of models, architecture, technology, and applications that provide this capability.…”

Abstract-As Model Based Systems Engineering (MBSE) practices gain adoption, various approaches have been developed in order to simplify and automate the process of generating documents from models. Essentially, all of these techniques can be unified around the concept of producing different views of the model according to the needs of the intended audience. In this paper, we will describe a technique developed at JPL of applying SysML Viewpoints and Views to generate documents and reports. An architecture of model-based view and document generation will be presented, and the necessary extensions to SysML with associated rationale will be explained. A survey of examples will highlight a variety of views that can be generated, and will provide some insight into how collaboration and integration is enabled. We will also describe the basic architecture for the enterprise applications that support this approach. and formal ontology expressed in the terminology and lexicon of each engineering domain. MBSE promises to alleviate the difficulty systems engineers face in communicating across engineering disciplines primarily in terms of completeness and consistency. By describing these systems in a formal way using domain specific terms, models can be checked for completeness and consistency. These models can also be analyzed to answer questions about the system such as input to simulations or other engineering analysis.At the core of realizing these benefits is effective commu- As MBSE practice has begun to move into the mainstream, several homegrown approaches have been developed around the use of the DocBook standard for publishing [6]. In general, these approaches involve the use of a SysML profile for DocBook to produce a model of a document. The document model is then linked to other SysML models and diagrams to produce the document.These approaches are effective at generating the basic structure of the document with injected model information. However, they lack the semantics and patterns to describe how the model is projected into a document structure. Each existing implementation has attempted different ways to support this, but none of these applications provides a comprehensive set of capability. They also lack a more fundamental concept and foundational support for describing how to extract information from the model in such a way so that analysis and editing of that information can be integrated with external applications.

Increasing complexity in modern systems, as well as cost and schedule constraints, require a new paradigm of Systems Engineering to fulfill stakeholder needs. Challenges facing efficient trade studies include poor tool interoperability, lack of simulation coordination (design parameters), and requirements flow down. A recent trend toward Model Based Systems Engineering (MBSE) includes flexible architecture definition, program documentation, requirements traceability, and Systems Engineering reuse. As a rapidly evolving practice, MBSE still lacks governing standards and commonly accepted frameworks. This paper proposes a framework for efficient architecture definition using MBSE in conjunction with domain specific simulation to evaluate alternatives. Variant modeling techniques are introduced as an extension to capturing parameterized architecture options. Initial exploration applies such variant modeling techniques to design for adaptability trade study criteria, as a means to evaluate candidate architecture configurations against multiple requirement sets. A general framework is provided, followed with a specific example including a method for designing a trade study, defining candidate architectures, planning simulations to fulfill requirements, and designing a weighted decision analysis to optimize system objectives.
