Multi-objective Optimization In
Reliability Based Design

Abstract
This paper discusses the development of a reliability-based multi-objective
design tool for solving structural optimization problems. The developed design
optimization tool has the capability to take into account the effects of variability
on the proposed design through a user specified reliability design criterion. The
nonlinear goal programming method used, provides for a design method that
eliminates the difficulty of having to define an objective function and
constraints, while at the same time has the capability of handling rank ordered
design objectives or goals. In this work, multiple design criteria including
structural weight, load induced stress, deflection, and mechanical reliability are
considered.
