An Internet Based Intelligent Argumentation System for Collaborative Engineering Design

Modern product design is a very complicated process which involves groups of designers, manufacturers, suppliers, and customer representatives. Conflicts are unavoidable in collaboration among multiple stakeholders, who have different objectives, requirements, and priorities. Unfortunately, current web-based collaborative engineering design systems do not support collaborative conflict resolution. In this paper, we will develop an intelligent computational argumentation model to enable management of a large scale argumentation network, and resolution of conflicts based on argumentation from many participants. A web-based intelligent argumentation tool is developed as a part of a web-based collaborative engineering design system based on the above model to resolve conflicts over the internet by enabling selection of the most favored design alternative in the design argumentation from multiple perspectives in collaborative engineering design

COMPUTER-SUPPORTED COLLABORATIVE KNOWLEDGE BUILDING IN ENGINEERING DESIGN

Engineering design is defined as a process of devising a technical system, component, or process to satisfy desired needs. Collaborative engineering design (CED) is a knowledge- intensive process that involves multidisciplinary people working jointly, sharing resources and outcomes, and building new knowledge while solving problems. People need to collaborate synchronously or asynchronously, either in the same place or distributed geographically. This thesis proposes that engineering design can be modeled not only as a process of knowledge transformation, but as a process of collaborative knowledge building (CKB). CKB is a goal-driven collaborative process of generating and refining ideas and concepts of value to the community. Properly applied and supported, CKB has the potential to improve both learning and design outcomes resulting from collaborative design projects. Existing collaboration tools have evolved without a clear understanding of designers’ needs, even though a portion of the required functionalities has been achieved separately. This thesis proposes an integrated CKB-orientated model for collaborative engineering design, incorporating the key elements of Stahl’s CKB model, Lu’s ECN-based collaborative engineering model, Nonaka’s knowledge creation theory, and Sim and Duffy’s model of a design activity. Based on the model, a set of specific requirements for collaboration tools are presented and some functionalities not existing currently are identified

Proposition d'une méthodologie de modélisation géométrique en contexte collaboratif

Today, Internet technology proposes communication, exchange and data storage powerful tools. They are standardized and accessible to the companies. But usually, they are not adapted for a mechanical design use and they do not take into account the design process. So, in this context, we present a method allowing the definition of real needs for collaborative engineering in terms of creation, management and exchange of technical data and more specially, geometrical data. From the results of this analysis, we propose a model on which is based a geometrical modelling methodology for mechanical products in a integrated design and collaborative engineering context

Collaborative Design of a Business Jet Family Using the AGILE 4.0 MBSE Environment

This paper presents the collaborative model-based design of a business jet family. In family design, a trade-off is made between aircraft performance, reducing fuel burn, and commonality, reducing manufacturing costs. The family is designed using Model-Based Systems Engineering (MBSE) methods developed in the AGILE 4.0 project. The EC-funded AGILE 4.0 project extends the scope of the preliminary aircraft design process to also include systems engineering phases and new design domains like manufacturing, maintenance, and certification. Stakeholders, needs, requirements, and architecture models of the business jet family are presented. Then, the collaborative Multidisciplinary Design Analysis and Optimization (MDAO) capabilities are used to integrate various aircraft design disciplines, including overall aircraft design, onboard systems design, wing structural sizing, tailplane sizing, mission analysis, and cost estimation. Decisions regarding the degree of commonality are implemented by optionally fixing the design of a shared component when sizing an aircraft

Towards a Technique for Modeling New Forms of Collaborative Work Practices – The Facilitation Process Model 2.0

Collaboration Engineering (CE) is an approach for the design and deployment of repeatable collaborative work practices that can be executed by practitioners themselves without the ongoing support of external collaboration professionals. A key design activity in CE concerns modeling current and future collaborative work practices. CE researchers and practitioners have used the Facilitation Process Model (FPM) technique. However, this modeling technique suffers from a number of shortcomings to model contemporary collaborative work practices. We use a design science approach to identify the main challenges with the original FPM technique, derive requirements and design a revised modeling technique that is based on the current technique enriched by BPMN 2.0 elements. This paper contributes to the CE literature by offering a revised FPM technique that assists CE-designers to capture new forms of collaborative work practices

Designing and Structuring the Invention process

This chapter describes how teachers can learn, design, and structure invention projects at school. Two process models are presented: project-based engineering and learning by collaborative design, highlighting knowledge creation, science, engineering, and design practices. By elaborating on these models and previous learning and designing by making research, the invention pedagogy process model and its structural phases is introduced. This model has been found to be beneficial in supporting the implementation of the project in practice. Through a case example from a university-level teacher education course, the focus is on how student teachers become acquainted with the invention pedagogy and pedagogical design of the invention project.Peer reviewe

Implementation challenges of annotated 3D models in collaborative design environments

Recent studies in the area of collaborative design have proposed the use of 3D annotations as a tool to make design information explicitly available within the 3D model, so that different stakeholders can share information throughout the product lifecycle. Annotation practices defined by the latest digital definition standards have formalized the presentation of information and facilitated the implementation of annotation tools in CAD systems. In this paper, we review the latest studies in annotation methods and technologies and explore their expected benefits in the context of collaborative design. Next, we analyze the implementation challenges of different annotation approaches, focusing specifically on design intent annotations. An analysis of the literature suggests that the use of annotations has a positive effect on collaborative design communication as long as proper implementation practices, tools, and user interaction mechanisms are in placeCamba, J.; Contero, M.; Salvador Herranz, GM.

An Experimental Methodology to Evaluate Concept Generation Procedures Based on Quantitative Lifecycle Performance

This study presents an experimental methodology to measure how concept generation procedures can affect the anticipated lifecycle performance of engineering systems design concepts. The methodology is based on objective and quantitative measurements of anticipated lifecycle performance of the design concepts. It merges cognitive and computer-aided techniques from the fields of collaboration engineering, creativity, and engineering design. It complements the body of existing techniques relying on subjective expert assessments, and other objective metrics not explicitly measuring anticipated lifecycle performance (e.g. development time and cost). Application of the methodology is demonstrated through evaluation of design procedures generating flexibility in engineering systems design. Experiments had ninety participants generate creative design alternatives to a simplified real estate development design problem. Thirty-two teams of two to three participants performed the collaborative design exercise. An online Group-Support System interface enabled efficient data collection and analysis. A computationally efficient mid-fidelity model was used to evaluate flexible design concepts quantitatively based on real options analysis techniques.Massachusetts Institute of Technology.
