GEOSS Model Based System Engineering Challenge team report for GEOSS AIP-6 By Lawrence E. McGovern, DSC INCOSE/WYLE Aerospace/Timothy Woodard, Tellus /Kenneth Druce , DCS Corp
Agenda for INCOSE GEOSS MBSE report • Societal Benefit Area(SBA) Alignment and Support effort • Development of RM-ODP Five Viewpoints for each AIP-6 Societal Based Areas (SBA) Agriculture, Disaster Management/Water • Small Unmanned Aerial Vehicle (sUAV) effort to develop processes for collection of data and provide it to user via GEOSS
RMP-ODP Standards • ITU-T Rec. X.901-X.904 • ISO/IEC 10746 • View Model Viewpoints addressed Volume 3 • Joint effort by the International Organization for Standardization (ISO), the International Electromechanical Commission (IEC) and the Telecommunication Standardization Sector (ITU-T)
RM-ODP Viewpointsand Modeling • Reference Model of Open Distributed Processing (RM-ODP) • reference model in computer science • coordinating framework for the standardization of open distributing processing (ODP) • It supports distribution, Internet working, platform and technology independence, and portability, together with an enterprise architecture framework for the specification of ODP systems
ODP Frameworks Descriptions The RM-ODP framework provides five generic and complementary viewpoints on the system and its environment: • Enterprise viewpoint- focuses on the purpose, scope and policies for the system • Information viewpoint - focuses on the semantics of the information and the information processing performed • Computational viewpoint - enables distribution through functional decomposition on the system into objects which interact at interfaces • Engineering viewpoint - focuses on the mechanisms and functions required to support distributed interactions between objects in the system • Technology viewpoint - focuses on the choice of technology of the system
Enterprise View • Use Case Realization process creates • Use case Diagram • Activity Diagram • steps of the Use Case Narrative become activities in the activity diagram • Sequence Diagram • These diagrams were completed in AIP-5
Transverse Use Case Realization • Steps in use cases are defined by the Transverse use groups • Use Cases will be subject to a Realization process that will yield an Activity Diagram and Sequence Diagram that will be part of the RM-ODP Enterprise Viewpoint • Transverse Use Cases provide for the Registering of data in Clearinghouse, Discover and Get Access and allowing User to Access Data from the provider • These will be captured in AIP-6
Information Viewpoint • Information Viewpoint • Focuses on the semantics of the information and the information processing performed • Describes the information managed by the system • Describes the structure and content type of the supporting data • These diagrams were completed in AIP-5
Computational View • Computational viewpoint • enables distribution through functional decomposition of the system into objects which interact at interfaces • describes the functionality provided by the system and its functional decomposition • Modeled as SysML Block Definition Diagram (BDD) • employs the concept of blocks to specify hierarchies and interconnection within a system design • describes relationships between blocks such as composition, association, and specialization • used as the object template Block Diagram
Engineering Viewpoint • Engineering viewpoint • focuses on the mechanisms and functions required to support distributed interactions between objects in the system • describes the distribution of processing performed by the system to manage the information and provide functionality • Modeled as an Internal Block Diagram (IBD) that has as it’s source a SysML BDD as shown in Computational View.
Engineering Components • Engineering view identifies types of components to support deployment and management of distributed interaction between the components and are consistent with Enterprise viewpoints • GEOSS is part of a System of Systems • Components are part of a service layer in a three tier model. Top used by users directly, Middle has business processes that respond to requests by clients and lower provides read/write access to data
Technology Viewpoint • Technology viewpoint • focuses on the choice of technology of the system. • Describes the technologies chosen to provide the processing, functionality and presentation of information. • Modeled using the Deployment Diagram
Small UAV Effort Progress • Considering Two Platform Options: • Rotary: • Advantages: Portable, Maneuverability, Customizable • Disadvantages: Less Endurance • Fixed Wing: • Advantages: Long flight times • Disadvantages: Must maintain horizontal motion therefore less maneuverable
Two Platforms: Agriculture SBA Disaster SBA Rotary Fixed Wing • Rapid , High Resolution Site Mapping • 2D and 3D Imaging • Portable Platforms Capable of Being Equipped with Various Sensors • Can be Operated in Very Close Proximity to Target Structures • Precision Management of Inputs: • Fertilizer • Pesticides • Seed • Water Distribution and Management • Stand and Crop Assessments Drought Monitoring
Small UAV Effort Progress • Preparation of 3 Minute video by September 2013 • Joint USIS/INCOSE effort • Will be presented to GEO Ministers (80 Countries) at GEO Plenary in Geneva, Switzerland January 2013 • First version of Video is provided next and is narrated and depicts an entire flight sequence showing how a flight to collect drought data would be conducted • The scenario of Drought covers the Disaster management/Agriculture/ and Water SBAs
Final Engineering Report • The sUAV team will prepare and deliver the 3 minute Video for the Ministers meeting and work with INCOSE to model sUAV Architecture model • The Architecture team will: • share the viewpoint results with each SBA team • resolve any changes required to viewpoint products • produce a final engineering report • include the results of all Viewpoints for • SBA Use Cases and Transverse Use Cases
