System of Systems/Enterprise Modeling

return to: MBSE Wiki Start

What's New - 2014

Welcome to the SoS/Enterprise Modeling Activity Wiki Page

Welcome to the SoS/Enterprise Modeling Activity Wiki page sponsored by the INCOSE MBSE initiative.

Please also join us in the LinkedIn group for INCOSE MBSE SoS Enterprise Architecture discussions at: MBSE SoS EA LinkedIn Group

Note: This is an open group, but requires LinkedIn registration…to gain access as a new member please register with LinkedIn (free basic membership) and link to the group above.

Purpose

The purpose of this activity is to foster interest and participation in the continuing efforts to model enterprise and system of systems level architecture specifications and frameworks. The focus areas include the DoD DODAF 2.0 MetaModeling, NATO NAF Modeling, UK MOD MODAF modeling, OMG UPDM 2.0, the BPMN and BPEL, SOAML, NDIA System of Systems committee efforts and NCOIC Network Centric patterns efforts.

Similar to the Systems Engineering initiatives to evolve away from document based descriptions of systems to a model base descriptions of systems, the SoS/Enterprise modeling focus is on the efforts underway to evolve from a document only description of Architectures, Capabilities, Programmatics, etc. to a more rigorous model based representation of all the perspectives involved in engineering at the SoS and Enterprise levels of abstraction.

As discussed in the Architecting Principles for System of Systems reference, not all System of Systems are alike and come in three broad categories Directed, Collaborative, Virtual with five principal characteristics:

  • Operational Independence of the Elements
  • Managerial Independence of the Elements
  • Evolutionary Development
  • Emergent Behavior
  • Geographic Distribution

Measure of Success

Engage the stakeholders, capture the stakeholder expectations and define the measures of success.

Some Examples of measures for our focus area:

MeasureDescription
Team MembershipNumber of active team members contributing to Wiki Pages, Discussion Groups and Webinars

Community OutreachNumber of references to INCOSE MBSE SoS/Enterprise Modeling in SE Literature
PublicationsNumber of publications by INCOSE MBSE SoS/Enterprise Modeling membership

Topic Overview / Description

There are many definitions and interpretations of Systems of Systems and Enterprise level analysis, architecting and engineering. For example, one definition of System of Systems includes: “ a class of problems that have unique characteristics, distinguishing them from “classic” systems, for example, unbounded context and usage, potentially emergent behaviors, large number of complex interactions, costly to fully verify and validate a priori…” These unique characteristics have lead the Systems Engineering and Architecting community to investigate new languages and frameworks to help better define these key System of Systems characteristics.

System of Systems Engineering

T. Saunders, et al, in “United States Air Force Scientific Advisory Board Report on System of Systems Engineering for Air Force Capability Development” SAB-TR-05-04, July 2005 included the follow table:


SoS Engineering Key Concepts

  • Legacy Systems
  • Dynamic Reconfiguration of Architecture
  • Service Oriented Architecture Enabler
  • Protocols and Standards to Enable Interoperable Systems
  • Added “ilities” or Quality Attributes
  • Federated Acquisition
  • Independent Systems
  • Concept of Operations Critical
  • Ongoing Experimentation
  • Converging Spirals

  • Architecture: The activity of designing any kind of system
  • Architecture Framework: An architecture framework establishes a common practice for creating, interpreting, analyzing and using architecture descriptions within a particular domain of application or stakeholder community
  • Enterprise Architecture: Enterprise Architecture is the continuous practice of describing the essential elements of a sociotechnical organization, their relationships to each other and to the environment, in order to understand complexity and manage change
  • Meta Model: Defines the language and processes from which to form a model
  • Meta Model: A model is a representation containing the essential structure of some object or event in the real world
  • System: A group of interacting, interrelated, or interdependent elements forming a complex whole
  • System of Systems: a class of problems that have unique characteristics, distinguishing them from “classic” systems, for example, unbounded context and usage, potentially emergent behaviors, large number of complex interactions, costly to fully verify and validate a priori
