This paper describes the objectives, the methodology, and the progress made in the project entitled "Product Redesign for Performance, Manufacture and Assembly'*. Redesign is the process of modifying or changing an existing design with the objective of improving one or more of its aspects. The aspects of an engineering design which concern us are performance, manufacture and assembly. The objec...

In both business training and higher professional education there is a clear shift towards competencybased learning to cope with fast technological and societal changes. Competencies can be construed as abilities that enable learners to recognize and define new problems in their domain of study and future work as well as solve these problems (Kirschner, van Vilsteren, Hummel, & Wigman, 1997). A...

The procedural steps for developing an expert system for designing signals at isolated intersections are described and the most important development issues for each step are discussed. The steps include problem analysis and definition, preliminary prototype specification, knowledge acquisition strategy development, prototype development plan, knowledge extraction, knowledge representation, too...

This paper presents an expert spindle design system strategy which is based on the efficient utilization of past design experience, the laws of machine design, dynamics and metal cutting mechanics. The configuration of the spindle is decided from the specifications of the workpiece material, desired cutting conditions, and most common tools used on the machine tool. The spindle drive mechanism,...

The goal of this project is to automate software design by accumulating knowledge and experience of human designers. This paper presents the CREATOR2, an experimental expert system for automatic software design, that simulates the behavior of human expert designers by applying the design process knowledge. In CREATOR2 the focus is on reproducing human cognitive processes and automating software...

Expert Judgement (EJ) is used extensively during the generation of cost estimates. Cost estimators have to make numerous assumptions and judgements about what they think a new product will cost. However, the use of EJ is often frowned upon, not well accepted or understood by non-cost estimators within a concurrent engineering environment. Computerised cost models, in many ways, have reduced the...

Formerly instructional systems design models have incorporated prescriptive linear phases of analysis, design and development, implementation and evaluation. While early adopters worked within these frameworks to develop online courseware, now in many institutions online development has been have centralised within both support units and online learning management systems. This paper uses the d...
