  • reflecting communication a key factor for successful collaboration between Embodiment Design and simulation
    Journal of Engineering Design, 2009
    Co-Authors: Anja Maier, Matthias Kreimeyer, Udo Lindemann, P. John Clarkson
    Abstract:

    The need for integration of computer-aided Design and computer-aided engineering environments stems from the business priority to reduce product cycle times. It is exacerbated by the coexistence of two different paradigms: a topological one in Embodiment Design and a functional one in simulation. This dualism places increasing demands on human communication between Design and simulation engineers. This paper claims that reflecting communication is a key factor for successful collaboration. Reflection is used in both senses of the Latin word ‘reflectare’: to trigger active thinking about and consideration of communication, as well as to mirror perceptions of a given situation by people collaborating. The paper reports on the development and application of a maturity-grid approach to diagnose the current and desired states of communication between Design engineers and simulation engineers in the car body development of a German automotive manufacturer. Results include three themes: one, the importance of un...

  • Search heuristics for constraint-aided Embodiment Design
    Artificial Intelligence for Engineering Design Analysis and Manufacturing, 2009
    Co-Authors: Raphael Chenouard, Laurent Granvilliers, Patrick Sebastian
    Abstract:

    Embodiment Design (ED) is an early phase of product development. ED problems consist of finding solution principles that satisfy product requirements such as physics behaviors and interactions between components. Constraint satisfaction techniques are useful to solve constraint-based models that are often partial, heterogeneous, and uncertain in ED. This paper proposes new constraint satisfaction techniques to tackle piecewise-defined physics phenomena or skill-based rules and multiple categories of variables arising in Design applications. New search heuristics and a global piecewise constraint are introduced in the branch and prune framework. The capabilities of these techniques are illustrated with both academic and real-world problems. Complete models of the latter are presented.

  • Design space exploration in Embodiment Design: an application to the Design of aircraft air conditioners
    International Journal of Product Development, 2009
    Co-Authors: Dominique Scaravetti, Patrick Sebastian
    Abstract:

    The Embodiment Design of aeronautic systems proves to be a difficult Design phase due to the variability in the system environment; the Design is often constrained by atmospheric conditions. These atmospheric conditions appear to be highly variable according to the flight phases of the aircraft. The difficulty when Designing air-conditioning systems for civil aircrafts is also inherent to the complexity of the coupling of the nonlinear physical phenomena inside of these systems (multi-physics, multi-scaling). Therefore, the Design space appears to be very broad and quite difficult to explore. Embodiment Design choices are relating to continuous and discrete Design variables while the system effectiveness is extremely sensitive to most of these Design variables. There is a lack of tools to support the investigation of the Design exploration space and Designer decisions at early stages of the Design process. In this paper, a method is proposed to generate feasible Embodiments and manage the compromise between various Design requirements. A digital tool based on the meta-heuristic of Genetic Algorithms (Gas) has been developed to investigate the Design problem. The selection of non-dominated solutions (Pareto) is used to identify relevant values for Design variables and to facilitate choices among the Design solutions of the air conditioning system.

  • solving an air conditioning system problem in an Embodiment Design context using constraint satisfaction techniques
    Principles and Practice of Constraint Programming, 2007
    Co-Authors: Raphael Chenouard, Patrick Sebastian, Laurent Granvilliers
    Abstract:

    In this paper, the Embodiment Design of an air conditioning system (ACS) in an aircraft is investigated using interval constraint satisfaction techniques. The detailed ACS model is quite complex to solve, since it contains many coupled variables and many constraints corresponding to complex physics phenomena. Some new heuristics and notions based on Embodiment Design knowledge, are briefly introduced to undertake some Embodiment Design concepts and to obtain a more relevant and more efficient solving process than classical algorithms. The benefits of using constraint programming in Embodiment Design are discussed and some difficulties for Designers using CP tools are shortly detailed.

  • Exploring Design spaces in the search for Embodiment Design solutions and decision support
    The Proceedings of the Multiconference on "Computational Engineering in Systems Applications", 2006
    Co-Authors: Dominique Scaravetti, Jerome Pailhes, Patrick Sebastian, Jean-pierre Nadeau
    Abstract:

    The Design of an air-conditioning system for a commercial aircraft, which functions in various life cycle stages, proves difficult because atmospheric conditions differ greatly according to the flight phase. This paper proposes the use of constraint programming in the exploration of Design spaces and the search for feasible Embodiments. This approach produces the best Design compromises between various Design objectives, whatever the life cycle stage. The entire Design space is explored for potential solutions and their performance assessed, thus allowing for decision support at the end of the Embodiment Design phase

  • Exploring Design space in Embodiment Design with consideration of models accuracy
    CIRP Annals - Manufacturing Technology, 2015
    Co-Authors: Nicolas Perry, Mehdi El Amine, Jerome Pailhes
    Abstract:

    Rework tasks in collaborative development projects dealing with immature Design concepts are very frequent and are responsible of cost overruns and schedule delays. Taking into account uncertainty and accuracy of models (and data) improves decision making according to strategic orientation for product development. Based on a real Design of light, slender but rigid collectors’ supports, multiple tools have been developed and tested to support decision making at different stages of development process. The objective of this paper is to investigate the integration of these accuracy evaluations into the Design process. This proposal is validated by the industrial development and validation.

  • structuring of Embodiment Design problem based on the product lifecycle
    International Journal of Product Development, 2005
    Co-Authors: Dominique Scaravetti, Jerome Pailhes, Jean-pierre Nadeau, Patrick Sebastian
    Abstract:

    Early stages of the Design process are often based on Designers' experience; assumptions and irreversible decisions restricting the solution space are taken. It is difficult to take into account simultaneously every requirement imposed by the different phases of the product life-cycle. In this paper, a method is proposed to perform the analysis of the Embodiment Design problem. It facilitates the search of the indispensable elements, suitable for structuring the preliminary Design phase. Our approach is performed for the relevant life-cycle situations of the product. A four level analysis (need, functions, organic structure and physical behaviours) is proposed. The set of structuring elements allow the Design problem definition as a Constraint Satisfaction Problem (CSP).

  • Aided Decision-Making for an Embodiment Design Problem
    Advances in Integrated Design and Manufacturing in Mechanical Engineering, 1
    Co-Authors: Dominique Scaravetti, Jerome Pailhes, Jean-pierre Nadeau, Patrick Sebastian
    Abstract:

    In the early phases of a traditional Design process, many decisions are made by Designers. For that purpose, they take advantage of their experience and company knowledge. These decisions are necessary in a sequential Design process but may hide many Embodiment solutions. Moreover, Designers often use a trial-and-error mode to find a working combination of standard elements. To overcome these difficulties, a decision support system based on constraint programming is proposed. The object of the Design process set out in this paper is to facilitate the Embodiment Design phase by avoiding a-priori decision making and searching for feasible architectures in which all the points of view of the various participants in the project are taken into account. A preliminary search of structuring characteristics of the Design problem is necessary and is detailed here. This methodology is applied to Embodiment Design of the automatic weight-winding system of a monumental clock. To determine the most interesting solutions , objectives and performance indicators are entered. Finally, the benefits of our approach are discussed.

  • Team composition to enhance collaboration between Embodiment Design and simulation departments
    Guidelines for a Decision Support Method Adapted to NPD Processes, 2007
    Co-Authors: Matthias Kreimeyer, U. Herfeld, Frank Deubzer, Mike Danilovic, Stefan Fuchs, Udo Lindemann
    Abstract:

    Efficient collaboration between Design and simulation departments is a key factor to efficient product development. There are numerous efforts to systematically “integrate” product development activities using CAD- and CAE-systems. This paper presents a team-based approach to render collaboration, i.e. communication and coordination, between the engineers involved in Designing and simulating the product more efficient. It is part of an overall integration strategy to support collaboration between the departments in question in terms of the product architecture and the engineers involved as well as information objects, tools, and the process.The team structures proposed combine the different ways of organization prevailing in Design and simulation. Based on a product architecture regarding both functional and geometry-oriented perspectives onto the product, virtual teams attributed to parts of this component-function-structure serve as a basis to enhance communication. This is intended to offer a means of orientation to coordinate common efforts between engineers involved. The paper lines out a method to compose teams that merge the necessary competences and responsibilities involved to foster communication across different engineers involved in a set of functions and components.

  • REFLECTING COMMUNICATION: A KEY FACTOR FOR SUCCESSFUL COLLABORATION BETWEEN Embodiment Design AND SIMULATION
    2006
    Co-Authors: Anja Maier, Matthias Kreimeyer, Udo Lindemann, U. Herfeld, Frank Deubzer, Pj Clarkson
    Abstract:

    Simulation is taking on an increasingly important role during the engineering Design process. It helps to reduce cost through early verification of Design concepts, making greater numbers of physical prototypes obsolete. The industrial need for closer integration of CAD (computer-aided Design) and CAE (computer-aided engineering) environments stems from the business priority to reduce product cycle times by reducing both iterations between the Embodiment Design department and the simulation department, and the time each single iteration takes. This paper reports on the construction and application of a maturity grid-inspired approach to diagnose the current and desired state of communication between Design engineers and simulation engineers in the car body development of a German automotive manufacturer.

  • Function-Driven Product Design in Virtual Teams Through Methodical Structuring of Requirements and Components
    Volume 1: Advanced Energy Systems Advanced Materials Aerospace Automation and Robotics Noise Control and Acoustics and Systems Engineering, 2006
    Co-Authors: Matthias Kreimeyer, U. Herfeld, Frank Deubzer, Cyrille Dequidt, Udo Lindemann
    Abstract:

    Today’s development process is mainly geometry driven and executed by a component-based organization of Design departments (in automotive development e.g. one department for body Design, one for interior Design etc.). Yet, Design departments developing complex products depend more and more on support from other departments. Therefore, these component-based organizational structures are not fully adequate. The product developed in these departments is — from the customer’s point of view — a set of functions that meet his needs, requiring the incorporation of different compromises from different aspects of Design for X. Typically, the individual functions do not have a direct, one-on-one relation with single components or assemblies but overlap with several components and assemblies. Therefore, at least two perspectives coexist in the Design of a product and particularly with respect to collaboration between Embodiment Design engineers and simulation engineers, that of functions and that of components. Hence, a manageable approach is needed to map components and functions. This paper proposes an approach to methodically compose function-oriented teams between Embodiment Design and simulation departments. These are meant to support cross-departmental communication to raise efficiency in the development process. The approach is implemented by interrelating components and functional requirements. To do so, the methodologies of Design structure and domain mapping matrices are used. The mapping provides the engineering departments with several opportunities: First of all, it provides transparency of the product’s functions as specified by the requirements and their interrelation with the product’s topology. This offers the Embodiment Design engineers a possibility to understand the involvement of “their” parts into the total product and the simulation engineer the possibility to find all parts involved in a function to be simulated. Thus it serves as a means to structure communication between the involved engineers. Furthermore, it allows conclusions to compose adequate roles and teams within the Design process. Adapting the approach of so-called “communities of practice”, a team structure across Design and simulation departments is proposed to form function-driven teams that are able to work together efficiently and target-oriented. This establishes well-defined channels of communication to foster efficient exchange of information among different departments such as Embodiment Design and simulation department.Copyright © 2006 by ASME
