KNOWLEDGE-BASED ROBUST PIPING DESIGN

Knowledge-based System for Taguchi’s Robust Design Model

This paper presents a model of generic knowledge-based system for the selection of optimal process parameters in multiresponse processes, that consists of three modules which (1) use expert system, designed for selecting an inner and an outer orthogonal array, to design the experimental plan, (2) use Taguchi’s quality loss function and multivariate statistical methods to adequately present resp...

Robust Design and Reliability-based Design Optimization

A large number of problems in manufacturing processes, production planning, finance and engineering design require an understanding of potential sources of variations and quantification of the effect of variations on product behavior and performance. Traditionally, in engineering problems uncertainties have been formulated only through coarse safety factors. Such methods often lead to overdesig...

Robust and Reliability-Based Design

The idea behind this special supplement came out of discussions with the Editor, Dr. Michael McCarthy, about the need to present some recent advances in the area of risk-based and robust design. We felt, and still feel, that there is an ever increasing need to design mechanical and structural systems that are risk tolerant and robust. It was our belief that it would be useful if, by way of a de...

Deterministic Design, Reliability-Based Design and Robust Design

Due to the inherent uncertainties or variabilities in loads, materials and manufacturing quality, variabilities are unavoidable in structural responses. To ensure the reliability of a structure, these uncertainties or variabilities must be considered during structural design. Through a simple cantilever box beam example, the concepts and practices of three design methodologies: deterministic de...
