Abstract
In this paper, the development and usage of rule-based design (RBD) in an industrial engineer-to-order (ETO) application is presented. First, three different design and geometric modeling processes are discussed for specifying customized bottle packaging systems, assemblies, and components. These processes include: (1) a manual method in which custom design specifications are uniquely created using two-dimension CAD software, (2) a custom in-house Visual Basic automated system built on a commercially available three-dimension solid modeling package, and (3) a commercially available rule-based system integrated with a commercially available three-dimensional solid modeling software tool. The advantages and limitations of the different modeling approaches are presented and evaluated qualitatively. Second, a detailed case study of an ETO sub-assembly is presented in which the third approach is used to create rule-based design applications. The rules for this sub-assembly are formulated and preliminary observations are reported. Guidelines for building and preparing solid models used in RBD are developed.
