Abstract
During the design or acquisition of missile systems the effectiveness of the system needs to be
evaluated. Often actual testing is not possible and therefore mathematical models need to be
constructed and solved with the aid of software. The current simulation model is investigated,
verified, and a mathematical model to aid in the design of the detonic payload, developed. The
problem is confined to the end-game scenario with the developed simulation model focusing
on the last milliseconds before warhead detonation. The model, that makes use of the raytracing
methodology, models the warhead explosion in the vicinity of a target and calculates the
probability of kill for the specific warhead design against the target. Using the data generated by
the simulation model, the warhead designer can make the necessary design changes to improve
the design. A heuristic method was developed and is discussed which assists in this design
process. There is, however, a large population of possible designs. Meta-heuristic methods
may be employed in reducing this population and to help confine the manual search to a
considerably smaller search area. A fuze detection model as well as the capability to generate
truly random intercept scenarios was developed as to enable employment of meta-heuristic
search methods. The simulation model, as well as design optimising technology, has successfully
been incorporated into a Windows based software package known as EVA (The Effectiveness
and Vulnerability Analyser).
