Start of COE The problem

• Evaluation of EADS TEWA• No local knowledge TEWA• ADA (previously handrolic)

The solution• COE at University of Stellenbosch• Multiple collaborators (industry & end-users)• Limited scope (fixed-wing, battery level)

5

LEDGER Ph I (past) Student projects(2004-2009)

• 2 x Honours (WA)• 6 x Masters (TE & WA)• 1 x PhD (TE)

Articles & Conferences• 2 x Articles (Orion OR Journal)• 30 x Presentations (ORSSA, IFORS &

LEDGER)

6

LEDGER Ph I (past) Student work

• Evaluation of EADS TEWA• Work in GBADS environment

End-user workshops• RRS workshops (Doctrine)• ADA school (Doctrine & Validation)

7

LEDGER Ph II (current) Student projects (2009-2010)

• 1 x Masters (UD) Utility theory in support of resource assignment Danie Lötter

• 1 x PhD (OOTW) Towards coastal TE DS Jacques du Toit

8

LEDGER Ph II (current) Development of TEWA CD

• 1st order TE subsystem• 1st order WA subsystem• Generic TEWA framework

End-user feedback• Defining of new models• Tweaking of model parameters• Support doctrine development

9

LEDGER Ph III (future) Ongoing student projects

• 1 x Masters• 1 x PhD

New student projects• 1 x Masters• Scheduling in real-time WA• Michelle van der Merwe

10

LEDGER Ph III (future) Development Capability

• Generic TEWA framework (c++) TE subsystem WA subsystem AM subsystem

• ADC testing environment (actual software)• Evaluation & testing (Matlab)• Close cooperation with DPSS

Invite to students & industry partners 11

LEDGER Ph III (future) Possible work (conventional warfare)

• TEWA or TERA on higher levels of AD• Hostility & Platform classification (TM-

related)

12

Possible topics Masters topic: Design of a TERA

system on ADA regiment level

Masters topic: Design of a TERA system on JAD level

PhD topic: Design of a WA subsystem in the GBAD environment (battery level)

13

LEDGER Ph III (future) Possible work (OOTW)

• Task force assignment for SAP Example: Soccer world cup 2010

• Border patrol• Coastal surveillance

14

Possible topics Masters topic: Design of a RA DSS in

a law enforcement environment

PhD topic: Design of a multi-timescale TE DSS with respect to drug trafficking and poaching in a marine and coastal management environment

15

Conclusion Thorough theoretical foundation Theory being applied End-user satisfied Generic TEWA framework

Future possibilities• Conventional warfare work• Operation other than war work
