  2. 1. Knowledge maturity as decision support in stage-gate product development : a case from the aerospace industry

    Author : Christian Johansson; Andreas Larsson; Marco Bertoni; Dave Randall; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Knowledge Maturity; Knowledge Management; Stage-Gate; Decision Support; Product Development; Product-Service Systems; Aerospace; Funktionella produkter;

    Abstract : In today’s fast-paced industry where fight for market share is fierce and reaching the market ahead of competition imperative, product development is a target for lead-time reductions. In this context, in product development in stage-gate processes, decisions need to be made even though knowledge and information are scarce and flawed. READ MORE

  4. 2. 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

  5. 3. Design for Producibility in Fabricated Aerospace Components - A framework for predicting and controlling geometrical variation and weld quality defects during multidisciplinary design

    Author : Julia Madrid; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Quality Assurance; Welding; Aerospace; Design for Producibility; Welding simulation; Variation Management; Design for Manufacturing; robust design;

    Abstract : In the aerospace industry, weight reduction has been one of the key factors in making aircraft more fuel efficient in order to satisfy environmental demands and increase competitiveness. One strategy adopted by aircraft component suppliers to reduce weight has been fabrication, in which small cast or forged parts are welded together into a final shape. READ MORE

  6. 4. Novel, yet similar: A similarity-assisted product family design approach for structural aero-engine components

    Author : Julian Martinsson Bonde; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; design support; aerospace; similarity metrics; aero-engine structures; design space exploration; engineering design;

    Abstract : The aviation industry is in a state of transformation. The climate crisis has amplified the need to innovate, and consequently manufacturers in the aviation industry need to investigate new and more sustainable design concepts. READ MORE

  7. 5. A System of Systems View in Early Product Development : An Ontology-Based Approach

    Author : Ludvig Knöös Franzén; Petter Krus; Christopher Jouannet; Ingo Staack; Kristian Amadori; Daniel DeLaurentis; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System-of-Systems; Systems Engineering; Ontology; Description Logic Reasoning; Design Space Exploration; Aircraft Design; Search and Rescue; Early Product Development;

    Abstract : The concept of system-of-systems is becoming increasingly common and relevant in many engineering applications. Today’s highly interconnected world entails that more and more systems have dependencies on other systems. READ MORE
