“…A design method is a scheme for organising reasoning steps and domain knowledge to construct a solution (Dasgupta 1989). Design methodologies are concerned with the question of how to design whereas the design process is concerned with the question of what to design.…”

This work focuses on a design methodology that aids in design and development of complex engineering systems. This design methodology consists of simulation, optimization and decision making. Within this work a framework is presented in which modelling, multiobjective optimization and multi criteria decision making techniques are used to design an engineering system. Due to the complexity of the designed system a three-step design process is suggested. In the first step multi-objective optimization using genetic algorithm is used. In the second step a multi attribute decision making process based on linguistic variables is suggested in order to facilitate the designer to express the preferences. In the last step the fine tuning of selected few variants are performed. This methodology is named as progressive design methodology. The method is applied as a case study to design a permanent magnet brushless DC motor drive and the results are compared with experimental values.

“…This approach has led, inter alia, many researchers to investigate psychological models of human thought as a basis for constructing the constituent methods within the AI design paradigm [79], [119]. We shall describe in the sequel those theories (which conclude, among others, [105], [55], [28], [5], [1], and [22]) that support the thesis that the engineering and Fig. 3.…”

“…Although there is no single model that can furnish a perfect definition of the design process, design models provide us with the powerful tools to explain and understand the design process. Design has been discussed in, among others, contexts such as general design methodologies [105], [52], [108], [36], [6], [21], [22], design artifacts representation [30], [48], [94], [122], [92], [83], computational models for the design process [78], [84], [91], [96], [120], [71], knowledge-based CAD systems [32], [117], [97], and design theories [46], [112], [124], [72], [73], [13].…”

“…Thus, the design activity is influenced by the designer's world view and values. Consequently, the recognition and identification of the design problem, the nature of the design solution, and the determination of valid research topics in engineering design are all intimately a function of the designer's perspective [22].…”

In this paper, we examine the logic and methodology of engineering design from the perspective of the philosophy of science. The fundamental characteristics of design problems and design processes are discussed and analyzed. These characteristics establish the framework within which different design paradigms are examined. Following the discussions on descriptive properties of design, and the prescriptive role of design paradigms, we advocate the plausible hypothesis that there is a direct resemblance between the structure of design processes and the problem solving of scientific communities. The scientific community metaphor has been useful in guiding the development of general purpose highly effective design process meta-tools [73], [125]. His research within engineering design focuses on developing methods to help the designer move from the conceptual phase to the realization of the physical device. To achieve this objective, he has developed the formal general design theory (FGDT), which is a mathematical theory of design. He has developed methods to solve routine design with group technology, genetic algorithms, and simulated annealing, to define computerized architecture, structure, and databases for the conceptual design process, and to develop a framework of logic decomposition and case-based reasoning methodology for mechanical design. He is also co-authoring, with O. Maimon, a book on the foundations of engineering design. Additional interests include real-time scheduling of flexible manufacturing systems, inventory management, risk and decision analyses, and group technology. His papers have been published in several journals, including the IEEE

“…Design distinguishes itself from PS in that it is alway s directed at the creation of an artefact (be it a physical or a symbolic one) . Design will therefore always attempt to answer the question of `what ought to be', distinguishing it fro m non-design PS answering questions of `what is' (Dasgupta 1989) . This particular setting of design provides the delta which makes it a uniquely identifiable specialised PS activity .…”

Abstrac tThe importance of software development expertise to our society and likewise the importanc e of education in this field are self-evident. At the same time it is undisputed that software development at the professional level is a complex activity . It must be presumed that th e make-up of expertise required to successfully complete such activities will itself be nonsimple, deserving of our attention . A hierarchical view of professional expertise is presente d and a method for determining the fundamental principles making up lasting expertise i s systematically derived . The method is applied to determine principles of software engineerin g expertise. The view presented provides a step towards a well founded understanding of th e types of expertise needed for the activity of software development . Educators involved i n courses releasing professionally recognised software developers should be interested t o examine which aspects of the expertise-derivation they already utilise and which aspects coul d further benefit their courses .
