13. Key Concepts - Why a BOM Approach? BOM –A piece part of a conceptual model, simulation object model, or federation object model, which can be used as a building block in the development and/or extension of a simulation or federation. • Offers modular way to represent simulation exchange elements • Platform independent (XML) • Captures / carries forward conceptual model • Allows implementations to be represented independently • Can be combined to form compositions (model aggregation) • Can be used to define container classes(entity instance aggregation) • Facilitates interoperability(the exchange of data) • BOMs can be mapped across different BOMs, FOMs and SOMs Federate(SOM) Sim / SystemA WeaponsEffect BOM 1 BOM 2 Theater WarfareRepresentation Detect / Jam Federate A Federate B - or - Federation(FOM) BOM 3 BOMAssembly RepairResupply Representation Composition Federate X CompositeInterface - or - BOM n Model#1 Model#2 RadioComms Aggregation Model#3 Model#n 13

Background • Large-scale simulations exercises • High entity loads • High degree of resolution needed • Undue strain on Federation • Network • CPU • RTI Performance* • Recognition that not all players need / care about each model / entity • Approaches: Resolution scaling and aggregation • Concern for “water down” effect • Lack of techniques • No common infrastructure Aggregation - the coupling of multiple models/entities into a single inclusive group 29

Definition Concept Standards BOM – A piece part of a conceptual model, simulation object model, or federation object model, which can be used as a building block in the development and/or extension of a simulation or federation.

31. a component-based standard describing reusable piece parts of a simulation or simulation space. BOMs can be used to document one or more of the following piece part elements: Conceptual Model Patterns of interplay State machines Entities Events Interface Description Object classes / attributes Interaction classes / parameters Mapping between Conceptual Model and Interface Description Used as a building block in the development and extension of a simulation and/or a federation of simulations. Provides developers and users a modular approach for defining and adding new capabilities to a federate or federation, for quickly composing object models such as HLA FOMs and SOMs through BOM Assemblies.

34. NetworkLoad CPULoad First Level Aggregation - Stage 1 – Pre-aggregation Here the responsibility of aggregation, although it can be advised by a web service like BASS, is upon the sending federate that owns the models / entities. He must use the aggregated interface / msg. The benefit is a reduction in the amount of messages being generated over the network by one federate. Entityinstances Modelsused SENDER models RECEIVER entities 34

35. NetworkLoad CPULoad First Level Aggregation –Stage 2– Interest Identification Here the responsibility of aggregation, although it can be advised by a web service like BASS, is upon the sending federate that owns the models / entities. He must use the aggregated interface / msg. The benefit is a reduction in the amount of messages being generated over the network by one federate. Entityinstances Modelsused SENDER models RECEIVER entities Interest level BASS 35

36. NetworkLoad CPULoad First Level Aggregation -Stage 3 – Aggregation Opportunity Here the responsibility of aggregation, although it can be advised by a web service like BASS, is upon the sending federate that owns the models / entities. He must use the aggregated interface / msg. The benefit is a reduction in the amount of messages being generated over the network by one federate. Entityinstances Modelsused SENDER models RECEIVER entities Interest level BASS Aggregate Triggers/Criteria • Proximity to a specific obstacle, entity or feature in the synthetic battlespace; • A change in the level of interest or significance regarding the specific domain a model supports; or • An increase (or decrease) in the physical entity load by the system and/or over the entire federation.

37. NetworkLoad CPULoad First Level Aggregation -Stage 4 –Distributed Aggregation Employed Here the responsibility of aggregation, although it can be advised by a web service like BASS, is upon the sending federate that owns the models / entities.

38. NetworkLoad CPULoad Second Level Aggregation -Stage 1 – Pre-aggregation Modelsused Here the responsibility of aggregation, which is also advised by a web service like BASS, is upon the recipient federate(s). The idea here is that the messages, once received by the federate, can then be pooled and represented as an aggregate locally by that receiving federate rather than as individual models or object instances that it has to hold in memory. The benefit of this is that it helps reduce the memory load and computing burden for those federate recipients.

42. The following slides consist of snapshots obtained within OneSAF Objective System during a simulation execution for the 2005 Fall SIW Demo. The entities displayed on the PVD are captured during a task operation as defined by the user. The task organization is as follows: BLUFOR Side Helicopters (Apache, Blackhawk, Chinook, Cobra, Longbow) Fixed Wing (F16 Falcon, A10 Thunderbolt, AC130U Global Hawk) Tanks (armored) Supply vehicles Heavy artillery guns Demo Scenario Snapshot • OPFOR Side • Heavy artillery guns • Infantry • Service vehicles • Mines / Bombs 42

43. The simulation environment consists of different entities acting independent of each other with a mix of objectives. In this simulation the blue force is assembling to engage the red force. 43
