Abstract
This paper describes the design research and manufacturing
work of a SME company to satisfy customer needs for
processing hot aggressive liquids in the metallurgical
industry. The optimal forms are large diameter vertical
process vessels and cost effective material alternatives are
glass fiber reinforced plastic and metal. The goal of the
producer is to maximise the customer satisfaction within the
technical and economic constraints. First global solutions are
innovated and analysed and then the optimal choice is
designed in detail. Realisable detail design innovations are
obtained using first creative heuristics and experience. Then
these are optimised with fuzzy satisfaction goals with discrete
design variables. Final designs are optimised with FEM and
checked with experimental testing.
