An Outline of a Method of Evaluating the Design Solutions

Łachwa A.

Machine Dynamics Research

2015

Vol. 39, No. 1

37-45

This paper presents an easy to use method to evaluate early design solutions created by a designer and/or generated by a machine. The method is based on the internal representation of design drawings in the form of hierarchical hypergraphs and on the project specification in the form of a list composed of two types of clauses: the elementary ones and the repeatable ones. These clauses represent goals and limitations imposed on the design by the customer. The evaluation value depends on the soft and hard elements of the specification, which are compared with appropriate accurate values of hypergraph attributes.

Function-structure computer-aided design model

Borkowski A., Grabska E., Hliniak G.

Machine Graphics and Vision

1999

Vol. 8, No. 3

367-381

This paper considers defining functional requirements of the designed object and transforming them into the object structure. The proposed Function Structure Editor (FSE) enables to bridge the gap between the design specification and the object structure. When utilising FSE the designer uses graph operations which are automatically transformed into graph rules allowing one to generate potential solutions of a given design problem. The proposed methodology is illustrated by examples of designing the teapot and the floor-layout of the house.
