• Aircraft 1 (turquoise) attacks Asset 1 (bridge) at time 125 seconds– Its threat values start to rise sharply just before 100 seconds

• Aircraft 2 (blue) attacks Asset 2 (airfield) at time 78 seconds– Its threat values are high and climb further just before 70 seconds

22


Future Activities: Masters Project 10

• The incorporation of utility functions into the objective function of a weapon assignment problem

– Objective is to be able to model various modes in which weapon assignment may take place (such as deterrence or attrition, for example) by means of utility functions

– Danie Lötter (to Commence 2010)

23


Future Activities: Masters Project 11

• Network threat evaluation and resource assignment

– Assign the minimum number of resources required to protect a network whose nodes model military infrastructure components and whose edges model line of sight, or access possibility

– Bernard Schlünz (to Commence 2010)

24


Future Activities: PhD Project 2

• Coastal threat evaluation decision support by means of pattern recognition and pattern mining

– Description: Management, filtering, classification and evaluation of intelligence data.

– Jacques du Toit (Commenced January 2009)

25


Future Graduate Research Topics

• Topic: Design of a resource assignment decision support system in a law enforcement environment

– Description: Implementation of a decision support system to aid the law enforcement authorities with the assignment of resources.

– Related honours studies: (hopefully one of the Honours students will enroll for the Masters programme)

• Topic: Design of a resource assignment system on ADA regiment level

– Description: Utility and assignment theory are used to design a decision support system for operators on ADA regiment level.

– Related honours studies: (hopefully related Honours student will enroll for the Masters programme)

• Topic: Design of a weapon assignment system in the GBAD environment

– Description: A decision support system is designed to propose possible engagement between threats and effectors in real-time.

– Related masters studies

Other Future Activities (2010-2012)

• Contract Research & Interest Development Projects– Further build Centre of Excellence

• Research Material – Postgraduate laboratory containing 12 PCs– Maintain and update equipment

• Workshops– Workshops with various military partners– Workshops with various industry partners

• Conferences– LEDGER 2010-2012– ORSSA 2010-2012– IFORS 2011


Medium Term Objectives

• Long term planning, 4 years, to ensure the sustainability of the centre of excellence

• Main objective to develop the first South African TEWA concept demonstrator for future GBADS phases (Ph2+) – in collaboration with Reutech Radar Systems

• Secondary objectives to develop or support development of DSSs:– TEWA on higher levels of ADA– TEWA or TERA in the JAD environment– TE DSS during Operations Other Than War (OOTW)

• Large Events• Peace Keeping

– Task force assignment of SAP– TE DS for coastal surveillance
