Here, we present a novel two-step approach for optimum design of cellular truss-beams based on desired natural frequencies. The proposed approach at- tempts to decrease the design complexities, based on the so called Axiomatic Design, before any eort to solve the physical problem itself. It also serves as a generic approach which nds its generality through dimensional analysis with its accuracy...

During the last couple of decades, the term complexity has been commonly found in use in many fields of science, sometimes as a measurable quantity with a rigorous but narrow definition and other times as merely an ad hoc label. With an emphasis on pragmatic engineering applications, this thesis investigates the complexity concept defined in axiomatic design theory to avoid vague use of the ter...

Software is playing an increasingly important role in manufacturing. Many manufacturing firms have problems with software development. Software engineering is still laborintensive and prone to errors. Industrial firms are under pressure to shorten the lead-time required in introducing new software, increase the reliability of their software, and increase their market share. Software must be des...

General Design Theory (GDT) is an axiomatic theory of design invented by Yoshikawa. In GDT, design is formulated by using topological spaces which is defined over the set of all entities. In this paper, we shall extend GDT and give a general model of design synthesis. Firstly, we shall introduce three kinds of spaces (a design specification space, an entity space, and a design space), and defin...
