2. 1. Conceptual Modelling of Tasks : A Design Pattern Approach from E-mail to Robots

   Author : Lars Oestreicher; Kerstin Severinson-Eklundh; Gerrit van der Veer; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Rehabilitation; therapy; Computer and systems science; Data- och systemvetenskap;

   Abstract : HTML clipboardThe thesis deals with the dual problem of finding out and modelling the needs of users in various situations and constructing models of supportive software. Task analysis has not been a very hot topic for research in the last years, but in my work I have tried to apply task analysis to certain application areas. READ MORE

4. 2. Complexity in transportation and logistics systems : A conceptual approach to modelling and analysis

   Author : Jonas Waidringer; Chalmers; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; management; measurement; logistics; modelling; complexity; transportation;

   Abstract : The basis for the thesis is to assess the usefulness of describing and analysing transportation and logistics systems as being complex systems. The reason and assumption being that in the future more integrated and sophisticated systems and solutions will be demanded. READ MORE

5. 3. Computational Methods in Conceptual Structural Design

   Author : Vedad Alic; Byggnadsmekanik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conceptual design; conceptual structural design; ground-borne vibrations; form finding; optimization; dynamic relaxation; graphic statics; reciprocal figures; strut-and-tie; finite element method; isogeometric analysis; NURBS; CAD; numerical modelling;

   Abstract : Conceptual design is the first phase in the design process in which all the requirements and design objectives are synthesized into conceptual alternatives. In practice today, major decisions regarding the buildings function, massing, and overall form are usually made during the first phase. READ MORE

6. 4. Towards automated conceptual design space exploration

   Author : Jakob Müller; Chalmers tekniska högskola; []
   Keywords : HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Design; Model Abstraction; Function Modelling; Knowledge Based Engineering; Model Based Design; Function-Means Modelling; Geometry Modelling; Design Space Exploration; Product Development; Systems Engineering; Design Automation; Aerospace;

   Abstract : In mature and safety-concerned industries, such as the aerospace industry, product development is often incremental and design solutions are limited to improvements of an existing design. Radical changes to the known product architecture are avoided, for reasons of reliability, lack of technology or lack of design space exploration (DSE) methods. READ MORE

7. 5. Constraint-based conceptual design using principle solution elements

   Author : Sören Wilhelms; Christian Weber; Linköpings universitet; []
   Keywords : Conceptual design; functional modelling; constraint-based design; design reuse; VDI 2222; product modelling; design support; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : The design of new products is an important engineering activity, and much of the competitiveness in high-salary countries depends on the ability to develop innovative products with acceptable time to market.During conceptual design, the principle solution for a product is conceived.
