  1. Henry Neimeier October, 2008 C4ISR Analytic Performance Evaluation CAPE Webinar

  2. Webinar Agenda • C4ISR Analytic Performance Evaluation CAPE concept brief • Command, Control, Communications, Computers, Intelligence, Surveillance, Reconnaissance • MILCOM 96 model demo • Precision Guided Munitions PGM Model Briefing & Demo • multivariate sensitivity analysis using Lonnie Library • Unclassified nominal data • Joint Dynamic Engagement Model JDEM Briefing • Military impact of space degradation • Analytica radar plots • Unclassified nominal data

  3. CAPE Concept • Analytic • Analytic network queuing and analytic risk evaluation • No discrete event statistical significance problem • Deterministic sensitivity analysis and parameter tuning • Short development cycle • Model evolution: daily modification • Analytica™ array abstraction capabilities • Appropriate aggregation: match data availability • Redland: summarize broad range of scenarios with distributions • Real time decision support • Execute on a portable in less than five minutes • Scroll through the multi-parameter space

  4. CAPE Principals • Model complex uncertain phenomena with aggregate probabilities • Represent uncertain environments with probability distributions • Processing, decision, execution, motion time distributions • Simple analytic calculations • No random number generation or sampling • Response surface inputs • Simulate simply • Fixed time step • Inputs for next time step are output expected values from previous

  5. Scenario Space Envelope • Identify key scenario characteristics that give rise to significant stress on C4ISR capabilities • Operational environment • Theater area • Terrain masking and delimitation • Foliage (urban) • Weather • Joint Suppression Of Enemy Air Defense JSEAD • Standoff operation • Attrition rates of sensors and attack platforms • Potential deployment rate • Infrastructure: communications, roads, air defense • Intelligence preparation of battlefield

  6. Dynamic CAPE Communication Improvements Sensor Improvements Processing Improvements Collection PEDS C2 Node Strike Platform Weapon CAPE Scope “Sensor-to-Shooter” Process More higher-value targets; greater likelihood of destroying target More information is collected, more frequently Probability of finding target is increased; sorties are more efficient More better-quality information is transmitted for processing; capacity and delay improvements Targets are identified more quickly Weapons are assigned more quickly Air Tasking Orders generated more quickly

  8. CAPE Tool Characteristics • Implemented in Analytica™ on PC • Employs analytic risk evaluation and analytic network queuing techniques • Overcomes several discrete event simulation limitations • Statistical significance • Causal chain, multi-parameter tuning • Fast model development employing library functions • Fast model execution: hundreds of runs per minute • All multi-runs in less than five minutes • Spanning scenario set • Arrow scroll through the multi-dimensional parameter space

  9. Discrete Event Simulation Time To Meet A Given Accuracy And Confidence Criteria T simulation time for a specified relative error  service time Ca interarrival time coe.variation Cs service time coe.variation Z unit normal deviate  utilization  tolerated relative error C E = 1 / P E = expected number of simulation events P = distribution tail probability C = uncertain model components

  10. Analytic Queuing As An Alternative To Discrete Event Simulation • Classical Assumptions • Steady state solution utilization <1 • Time to reach steady state increases as utilization increases (becomes infinite at unity utilization) • In practical problems loading changes before steady state is achieved • New approximation technique • Approximate transient solution • Utilization >1 build backlog that is worked off when utilization is less than 1 • Networks of queues (G/G/n Priority/No) • Calculation of factor effects in many parameter problems is now possible • Use baulking utilization to trade off delay time against throughput

  11. Analytic Risk Evaluation • Obtain the entire result probability distribution as a function of uncertainty in input parameter values • Entire probability distribution vice an uncertain estimate of the mean • Dynamic analytic risk evaluation (uncertainty flow from source to resultant measures of effectiveness) • Model a time varying workload and obtain uncertainty distribution over any time interval • Simplified parametric sensitivity analysis • Change in result per unit change in input factor • Maintain the causal chain between factor and result • Reduces model development and execution time

  12. Analytic Risk Evaluation Distributions • Beta distribution • Fit based on minimum, mean, maximum, standard deviation statistics • Sums and products of beta variates are beta distributed (close approximation, also works with functions) • Triangular distribution based on minimum, mode, and maximum statistics • Faster calculation used early in development • Method: • keep a running calculation of the minimum, mean, maximum, standard deviation, mode statistics through the calculation • fit probability distribution based on the above statisitics when desired
