Compromise Solutions

AbstractConflicts are likely to arise among participants in a collaborative design process as the inevitable outgrowth of the differing perspectives and viewpoints involved. The opportunities for conflict are magnified if many perspectives are brought to bear on a common artifact early in the design process, as in concurrent engineering or integrated engineering. Design advice tools can assist in the process of resolving these conflicts by making critiques and suggestions conveniently available to design participants, and by offering a fair means of evaluating and comparing suggested alternatives for compromise solution. In previous work we introduced a protocol based on notions of economic utility by which design advice systems can recognize conflict and mediate negotiation fairly. This protocol allowed design teams to express the desire to maximize or minimize the values of design parameters over totally ordered bounded domains of values, such as real numeric intervals. In this paper we extend this approach by allowing expressed preferences of design teams to be qualitative as well as quantitative, by allowing teams to express interest in parameters before they actually come into existence, and by relaxing many other of the earlier restrictions on the ways teams may express their preferences.

Wikis, freely editable collections of web pages, are showing potential for a flexible documentation and communication tool for collaborative design tasks. They also provide a medium that can be further transformed by properly understanding both the need for flexibility as well as support for design thinking early in the design process. The purpose of this work is to analyze the different dimensions of the wiki from a communication perspective as applicable to design. With a focus on communication in design, we will explore the advantages and disadvantages of using wikis in student engineering design teams. Our ultimate goal is to better support the design process while exploiting the potential for increasing the shared understanding among teams using a wiki. By introducing a wiki in a globally distributed product development course, students gain hands-on experience in using wikis as a design tool. Feedback from students will be collected through questionnaires and used to improve and transform the wiki as a support tool for communication during early design collaboration.

Successful collaborative design requires in-depth communication between experts from different disciplines. Many design decisions are made based on a shared mental model and understanding of key features and functions before the first prototype is built. Large-Scale Immersive Computing Environments (LSICEs) provide the opportunity for teams of experts to view and interact with 3D CAD models using natural human motions to explore potential design configurations. This paper presents the results of a class exercise where student design teams used an LSICE to examine their design ideas and make decisions during the design process. The goal of this research is to gain an understanding of (1) whether the decisions made by the students are improved by full-scale visualizations of their designs in LSICEs, (2) how the use of LSICEs affect the communication of students with collaborators and clients, and (3) how the interaction methods provided in LSICEs affect the design process. The results of this research indicate that the use of LSICEs improves communication among design team members.

AbstractFraming is a crucial skill for connecting problem and solution spaces in the creative design process, both for individuals and teams. Frames are implicit in individuals’ cognitive thinking, but the creation of shared frames plays a vital role in collaborative design. Many studies have attempted to describe the framing process, but little is still known about how to support designers in framing, specifically in teams. This paper addresses this gap, by exploring the connection between sketching and framing within interdisciplinary teams. Following a qualitative and explorative approach, we have investigated the process and outcome of five interdisciplinary teams. We identified that sketching assists in the creation and elaboration of frames. Furthermore, in tandem with discussion and reflection, sketching helps increase the chance of a frame to survive within the design process. Our findings have practical and educational implications for improving the creative design process in interdisciplinary teams.

Iteration in design has different meanings, ranging from simple task repetition to heuristic reasoning processes. Determining the need to iterate is important to improve the design process on cost, time, and quality, but currently there is no categorization of iterations conducive to this goal. After exploring the possible causes and attempts to address them, we propose to classify iterations as rework, design, or behavioral. This framework suggests that design teams should try to eliminate rework iterations, perform design iterations without skipping abstraction levels, and do behavioral iterations in parallel.

Target Value Design

Target value design is a new practice in the construction industry promoting concurrent engineering and collaborative design. This paper shows the results of literature survey to identify the influencing factors in the target value design. The paper also presents the results of a questionnaire survey to explore the industry practitioners' perception of the relative importance of the influencing factors. Project stakeholders participating in the survey consider the integration of different project stakeholders in the design phase as critical. The project definition is also regarded as essential in implementing the target value design. However, the market conditions and project attributes are considered as least significant in the target value design process.

Abstract Collaborative engineering involves multiple engineers and managers working together to develop engineering products. As the engineering problems become more and more complicated, new technologies are required to achieve better effectiveness and efficiency. While process models management and technologies have been developed to support engineering design, most of them apply only to routine design tasks and do not explicitly deal with the change of processes during execution. Our research proposes a process-driven framework to support collaborative engineering. The framework is composed of a process model that captures both high level and low level activity dependencies, an agent network that monitors process execution and facilitates coordination among engineers, and a Petri-net based modeling tool to represent and analyze process features and predict the performance of engineering processes. In this paper, we first describe a simple collaborative design problem and our proposed ActivePROCESS collaborative engineering framework. After that we present our Petri-net based analytical model of collaborative design process and discuss the model along with a case example.

Modeling Methodology

The design process can be viewed as a series of actions for reducing uncertainty in product or system design specifications. At the beginning of the design process, uncertainty is high because the design space has yet to be explored and decisions have not been made. This uncertainty contributes to design risk, risk due to the engineer’s lack of knowledge and/or information. In design teams, design risk takes on the added dimension of lack of group awareness about the state of knowledge of each team member. To better understand and capture uncertainty inherent in early design, we have developed a methodology to model design evolution in concurrent design teams. The representation is a directed graph that represents the state of a design over time. In this paper we describe our modeling methodology and present a case study of two different design teams. We present the results of modeling a part of the design process. Then we show how the model can be analyzed to understand how information and knowledge transfer was used to make decisions and reduce uncertainty and design risk.

Abstract This paper describes the change management capabilities of a data management model to support engineering design. Specifically, it addresses the problem of detecting changes made to a design during a CAD session and efficiently maintains an evolving description of a primitive entity through the design process. We propose a hierarchical versioning model to support the independent evolution of alternative deigns for a primitive entity and provide operators to store and manage changes among versions in a particular derivation hierarchy. In addition, we present a scheme to represent the version model in a CAD paradigm. The version model presented in this paper is a component of a larger data management model of versions, assemblies, configurations to address the change management needs of collaborative design.

To input rational customer requirements into engineering design process more effectively and improve product design quality and market response efficiency, this paper focuses on the interaction between market analysis and engineering design decision for the modular product. While many researchers have successful evaluated and optimized the design schemes, few, if any, have provided a bridge the customer selection and firms product development decision. After a review of the literature we introduce the flow of user-engineering design interaction including both maximize the utility of customer and the profit of the firm. On the user and market analysis flow, customer requirements are defined according to the target market, then the customer selection possibility link to the product attributes by utility function. Accordingly, the alternatives are corresponding to the module different product, and then using decision support problem method to search the optimal design parameters. Two design domains can share the design information and realize the cooperative design process by computer computing platform.
