This thesis provides a methodological contribution to architecture selection in the preliminary design of fault-tolerant aircraft systems. Therefore, an existing analytical model for safety and reliability analysis has been enhanced by including aspects of redundancy allocation using three conditioned multi-objective optimization algorithms. As objective functions safety and reliability of different failure conditions of complex logics can be considered, beside additional contradictory, summative component parameters, such as estimating the system mass. A hierarchical decisionmaking process is used for further reduction of the determined Pareto set. Conclusively, the method is applied to the design of an electrical power generation and distribution system.
