System design optimisation involving phased missions
The performance of a phased mission is defined as a succession
of non-overlapping phases that constitute towards a continuous mission. The
focus of this paper is to develop a method to construct an optimal design
structure for a phased mission system when available resources are restricted
and to ensure a minimal system failure probability throughout the whole
mission. The implemented optimisation method employs fault tree analysis to
represent the causes of failure in the system for each phase. Binary decision
diagrams are used to quantify the failure probability of each phase and the
whole mission, and a single objective genetic algorithm is chosen to solve
the optimisation problem. Analysis of the optimisation process of a military
vessel design during a training mission is presented and the obtained results
are discussed.
