Achieving Tradeoffs between Safety and Functionality in Early System Design
Abstract
In this paper, we propose a novel method that helps designers to form design concepts that achieve optimal tradeoffs among functionality, cost, profit and safety early in the design. The method combines genetic algorithms with preliminary risk analysis and is largely automated thus satisfying the preconditions for application in complex systems. A Pareto multi-objective optimisation approach helps to generate a set of design concepts that represent optimal solutions for different levels of expenditure and risk, while the final decision on which design concepts are most promising is left to humans.
