SYSTEMS ENGINEERING APPROACH TO SYSTEM REALISATION P. Srikumar

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
