  1. Formulating theSystems Engineering Concept Model (SECM) Part 2: Kernel Base Concepts Presenting: Charles Galey Christopher Delp Robert Karban MagedElasar

  2. Previously on SECM… • In part 1 we discussed: • Motivation • Approach • General Agreements: • Name: “Systems Engineering Concept Model (SECM)” • Associations and Sub-Classes are used to relate Concepts (i.e. MOF like) • Concept of Kernel and Library separation • Include definitions with each concept • Track open issues in JIRA • Actions • Post part 1 slides (Complete) • Create SECM wiki from WG page (Complete)

  3. Kernel BASE Concepts

  4. SECM Principles • Simple and parsimonious • Patterns to ensure symmetry and consistency • Extensible • SE domain concepts build on Kernel concepts • E.g., System subclasses Block • Avoid circular dependencies • …

  5. Kernel Concepts • Base Concepts • Element • Container • Model • Comment • Relationship • Classifier (i.e. Block) • Feature (i.e. Property) • ValueSpecification • Additional kernel concepts sub-class the base concepts Kernel concepts intended to be domain neutral

  6. Kernel Base Concepts

  7. Backup

  8. Well Formed • Avoid circular dependencies • Oliver model utilized sequenced definitions to avoid circular dependencies • Our model will allow the identification of these dependencies via inspection

  9. Simple and Parsimonious • Types define properties • A Property typed by a Quantity is a “Value Property” • No additional enhancements are specified

  10. Extendable • Enable light weight groupings of concepts and libraries • The SECM Consists of two element groups the Kernel and the Libraries • Elements in libraries will need to be grouped in multiple ways • These groupings will need to be discovered • For example a “Requirement view” might exist in both a view library and a V&V library
