Abstract
The objective of this paper is to present a multiobjective approach to design for reliability. A method is presented that integrates performance in all salient respects, from component failure to system/product performance, that have a direct bearing on whether or not the system/product will perform its required functions. The method can be used to improve the reliability of existing systems/products, to compare different systems/products or to perform a multiobjective optimization to yield the most reliable solution. This paper presents the principles of the method and a case study to illustrate how the method is applied. The case study concerns the analysis of a continuous steel casting mould and surrounding equipment and illustrates how process and equipment parameters can be integrated to investigate the reliability of the total system.
