  1. SYSTEMS ENGINEERING APPROACH TO SYSTEM REALISATION P. Srikumar

  2. SE - THE STARTING POINT • LITERATURE ON THE SUBJECT • LECTURES ON THE SUBJECT • IMPLEMENTATION TOOLS • EXAMPLES • OUR PRACTICAL PROBLEMS • IDENTIFY YOUR SYSTEM / SUBSYSTEM

  3. CONCEPT OF OPERATION • Eg: Long Range / Endurance UAV • REQUIREMENT FOR THE MISSION • PLAN THE MISSION • PREPARE SYSTEM • TEST SYSTEM • LAUNCH / TAKE OFF • CRUISE – NAVIGATE, ALTERNATE MISSION • LOITER IN AREA INTEREST FOR RECCY / SURVEILLANCE • TRANSMIT INFORMATION • RETURN CRUISE • LAND BACK & REFURBISH

  4. ALLOCATION OF FUNCTIONS TO SYSTEMS • GROUND CONTROL STATION • MISSION PLANNING & CHECKOUT SYSTEM • MISSION MONITORING & CONTROL SYSTEM • LAUNCHER / RUNWAY • AIR VEHICLE • PAYLOAD • COMMAND & DATA LINK • FUNCTIONAL REQUIREMENTS

  5. PERFORMANCE REQUIREMENTS • OPERATIONAL SPEED • MIN & MAX SPEED • ALTITUDE OF OPERATION • RANGE / RADIUS OF ACTION • ENDURANCE / MISSION TIME • PAYLOAD • OPERATIONAL REQUIREMENTS

  6. SYSTEM REQUIREMENTS • COMPLETE UNDERSTANDING & APPRECIATION OF • OPERATIONAL REQUIREMENTS VERIFIABLE • STORAGE, HANDLING • PREPARATION, TESTING, DEPLOYMENT • OPERATIONAL FLEXIBILITY, RELIABILITY • PERFORMANCE REQUIREMENTS MEASURABLE • ACCURACY, RANGE, ENDURANCE • SPEED, ALTITUDE • FUEL, PAYLOAD

  7. CAPABILITY ANALYSIS • TO ESTABLISH MATURITY OF • EXPERTISE • TECHNOLOGIES • ENGINEERING • INFRASTRUCTURE • FUNDS • VIABILITY CAPABILITY TO DEVELOP A VIABLE & USEFUL SYSTEM IN TIME & WITHIN REASONABLE COST “TECHNOLOGY READINESS LEVEL”

  8. STAKEHOLDERS • USER • PRODUCTION AGENCY • THE ORGANISATION • PROGRAM GROUP • DESIGNER • DEVELOPERS • OTHERS

  9. REQUIREMENTS ANALYSIS TOP LEVEL REQUIREMENTS SPECIFICATIONS • SINGLE-STEP PROCESS • - NO ANALYSIS • - NOT ACCEPTABLE LOWER LEVEL REQUIREMENTS

  10. REQUIREMENTS ANALYSIS TOP LEVEL REQUIREMENTS DRAFT SPECIFICATIONS LOWER LEVEL REQUIREMENTS

  11. REQUIREMENTS ANALYSIS TOP LEVEL REQUIREMENTS CAPTURE & AUDIT THE RESOLUTION OF ISSUES RAISED DRAFT SPECIFICATIONS QUERIES & CLARIFICATIONS LOWER LEVEL REQUIREMENTS

  12. REQUIREMENTS ANALYSIS TOP LEVEL REQUIREMENTS DRAFT SPECIFICATIONS FINAL SPECIFICATIONS QUERIES & CLARIFICATIONS LOWER LEVEL REQUIREMENTS

  13. REQUIREMENTS ANALYSIS SYSTEM REQUIREMENTS FINAL SPECIFICATIONS SUBSYSTEM REQUIREMENTS

  14. REQUIREMENTS ANALYSIS TOP LEVEL REQUIREMENTS DRAFT SPECIFICATIONS FINAL SPECIFICATIONS QUERIES & CLARIFICATIONS LOWER LEVEL REQUIREMENTS LOWEST LEVEL REQUIREMENTS

  15. THE REQUIREMENTS FLOW SYSTEM LEVEL R1 R2 REQUIREMENTS R3 SUBSYSTEM LEVEL R4 R5 R6 COMPONENT LEVEL R7

  16. THE REQUIREMENTS FLOW UAV SYSTEM AIR VEHICLE CNG SYSTEM MISSION COMPUTER PROCESSOR BOARD

  17. REQUIREMENTS ‘NODE’ SYSTEM SUBSYSTEM 2 SUBSYSTEM 3 SUBSYSTEM 1

  18. REQUIREMENTS TO SPECIFICATIONS • DESIGN & ANALYSIS TOOLS • EMPIRICAL METHODS • BLOCK DIAGRAMS • FLOW CHARTS • MODELING & SIMULATION • SURROGATE MODELS • DETAILED MODELS SYSTEM SUBSYSTEM 2 SUBSYSTEM 1 SUBSYSTEM 3

  19. THE SPECIFICATIONS FLOW SYSTEM LEVEL S1 S2 SPECIFICATIONS S3 SUBSYSTEM LEVEL S4 S5 S6 COMPONENT LEVEL S7

  20. VERIFICATION & VALIDATION PERFORMANCE VALIDATION SS SP SSS3 SSP3 SSP1 SSS1 SYSTEM INTEGRATION SSS2 SSP2 PERFORMANCE VERIFICATION SS : SYSTEM SPECS SSS : SUBSYSTEM SPECS SP : SYSTEM PERFORMANCE SSP : SUBSYSTEM PERFORMANCE V & V - HOW ?
