Executable Architecture of Net Enabled Operations: State Machine of Federated Nodes Mr. Mark Ball (DRDC CORA*) – Presenter Mr. Ron Funk (DRDC CORA*) Mr. Rick Sorensen (Vitech Corp.) 12 th ICCRTS, Newport, RI, USA June 19-21, 2007 * Defence R&D Canada – Centre for Operational Research and Analysis Canada Defence Research and Recherche et développement Development Canada pour la défense Canada
Outline • Introduction • Decision Logic – Background – Extensions beyond OPCEN SM – TPED vs TPPU – Node-specific logic • Conceptual basis (Producer, Consumer, Discovery, External, – OV-1 Repository) – PRC • Input Data Files • Implementation in • Way Ahead COREsim Defence R&D Canada – CORA • R & D pour la défense Canada – CARO
Background • Goal: develop capability-engineering analysis tools to support the building, demonstration, and analysis of executable architectures. • OPCEN State Machine Defence R&D Canada – CORA • R & D pour la défense Canada – CARO

SMOFN Execution • Flowchart represents a moment in time • Decision logic executes entirely for one time step • Time steps forward, logic repeats, accounts for changes in job states Defence R&D Canada – CORA • R & D pour la défense Canada – CARO
What SMOFN Accounts For • Data-driven simulation: – Uses files to build customized job workflows and configure any combination of nodes without affecting the business logic. • Accounts for the following overhead activities: – Tracking consumer perception of product utility as it accrues and decays; – Consolidation of products into higher-level aggregated products; and – Triggering new jobs where needed whenever relevant data becomes available.

What SMOFN Does That OPCEN SM Couldn’t Do • Nodes other than Producer – Discovery threads – Interaction between nodes • More flexibility in job steps – Unlimited number – Step names Defence R&D Canada – CORA • R & D pour la défense Canada – CARO
What the Producer Does • Only node in OPCEN SM • Converts raw data into analyzed products • Progress is tracked step by step • Job state accounts for – Utility accrued / decayed – Operators involved – Time spent / left Defence R&D Canada – CORA • R & D pour la défense Canada – CARO
What the Repository Does • Transfers information between nodes according to OV-1 Defence R&D Canada – CORA • R & D pour la défense Canada – CARO
What the Consumer Does • Receives Products from Repository • May generate Questions some time after receiving each Product Defence R&D Canada – CORA • R & D pour la défense Canada – CARO
What the Discoverer Does • Jobs defined similar to Producer • Jobs start when Questions received • Three possible results – All required data found – Some required data found – No required data found • Found data triggers new analysis job at Producer • Missing data triggers Query to External Sources Defence R&D Canada – CORA • R & D pour la défense Canada – CARO
What the External Sources Do • Logic similar to Consumer • Receives Queries from Repository • Generates Responses some time after receiving each Query Defence R&D Canada – CORA • R & D pour la défense Canada – CARO
Data Files • Describe general characteristics of each thread • Describe each step within thread • Describe OPCEN configuration • Describe product delivery Defence R&D Canada – CORA • R & D pour la défense Canada – CARO

Work in progress • Customization of SMOFN is underway to make data files representative of new Canadian Forces Command structure – OPCEN config – Job threads (reporting & response process, daily brief) • Data remains outside model until runtime – model itself remains unclassified Defence R&D Canada – CORA • R & D pour la défense Canada – CARO
