Design Information

The paper presents a new model for collaborative design. The model is analogous to electrical circuits with current (rate of design artifact synthesis and analysis), voltage (knowledge that drives the design process), and resistance (barriers to the exchange of design information). The resistances are identified from a collaborative design taxonomy. This model is illustrated through a simple example. Extensions and an assessment of the model are provided.

Computational Reasoning

Information representation in engineering design is currently dominated by top–down approaches such as taxonomies and ontologies. While top–down approaches provide support for computational reasoning, they are primarily limited due to their static nature, limited scope, and developer-centric focus. Bottom–up approaches, such as folksonomies, are emerging as means to address the limitations of top–down approaches. Folksonomies refer to collaborative classification by users who freely assign tags to design information. They are dynamic in nature, broad in scope, and are user focused. However, they are limited due to the presence of ambiguities and redundancies in the tags used by different people. Considering their complementary nature, the ideal approach is to use both top–down and bottom–up approaches in a synergistic manner. To facilitate this synergy, the goal in this paper is to present techniques for using dynamic folksonomies to extract global characteristics of the structure of design information, and to create hierarchies of tags that can guide the development of structured taxonomies and ontologies. The approach presented in this paper involves using (a) tools such as degree distribution and K-neighborhood connectivity analysis to extract the global characteristics of folksonomies and (b) set-based technique and hierarchical clustering to develop a hierarchy of tags. The approach is illustrated using data from a collective innovation platform that supports collaborative tagging for design information. It is shown that despite the flat nature of the folksonomies insights about the hierarchy in information can be gained. The effects of various parameters on the tag hierarchy are discussed. The approach has potential to be used synergistically with top–down approaches such as ontologies to support the next generation collaborative design platforms.

Abstract Collaborative design projects place additional burdens on current design documentation practices. The literature on group design has repeatedly documented the existence of problems in design decision making due to the unavailability of design information. This paper describes a data representation developed for collaborative mechanical design information. The data representation is used to record the history of the design as a sequence of design decisions. The resulting knowledge base records the final specifications, the alternatives which were considered during the design process, and the designers’ rationale for choosing the final design parameters. It is currently used in a computerized knowledge base system under development by the Design Process Research Group (DPRG), at the authors’ institution (OSU).

Modeling Environment

Design collaboration is recognized as an effective approach in joint problem solving to achieve success of product development in distributed and heterogeneous environments. Design collaboration involves communication of design information, coordination of design activities, and negotiation of design conflicts between multi-disciplinary teams. To support these critical requirements in collaborative design, methodologies and software systems are needed. This paper shares our experience in the method and software development for a Web-enabled engineering object modeling environment. It presents our methods for interoperable and extensible design information modeling, for intelligent object behaviors embedment in CAD models, and for design information sharing across product lifecycle applications through a common vocabulary. The prototype implementation of the modeling environment provides standardized and localized engineering objects embedded with design semantics and intelligent behaviors for the information needs from multiple engineering software applications. The prototype also provides activity coordination and negotiation facilities through team setting, online visualization, live updating, conflict management, and messaging. Use scenarios are discussed in the paper.

Future Design

Efficient computer support of product innovation processes has become an important issue of industrial competitiveness in the last forty years. As a consequence, there has been a growing demand for new computer-based tools and system. Various hardware, software and knowledge technologies have been used over the years as the basis of design support systems. With the appearance of network technologies, the conventional standalone workstation paradigm has been replaced by the paradigm of web-interconnected collaborative environments. Currently, the emerging and rapidly proliferating mobile and ubiquitous computing technologies create a technological push again. These technologies force us to reconsider not only the digital information processing devices and their interconnection, but also the way of obtaining, processing and communicating product design information. Many researches and laboratories are engaged with the development of novel concepts, architectures, tools and methods for next-generation design support environments. They will integrate many resources of the current collaborative design environments with pervasive computing functionality and large-scale mobility in a volatile manner. Part of the design support tools will have fixed location, but will be remotely accessible through wireless networks. Other part of the tools will be moving with the designers as portable, embedded, wearable and transferable devices, and will feature ad hoc connectivity. These not only offer new ways for aggregation, processing and presentation of design information, but also enable alternative ways of completing design activities. Our current research concentrates on three interrelated main issues: (i) studying workflow scenarios for future design support environment, (ii) investigation and integration of multiple technologies into an ad hoc interconnected heterogeneous infrastructure, and (iii) exploring efficient methods for utilizing new affordances in supporting product innovation. In this paper we report on the results of our recent technology study that analyzed the current results and trends of ubiquitous technology development, and tried to form a vision about the possible manifestation of future ubiquitous design support environments. Essentially, they have been conceptualized as ad hoc and volatile networks of fixed and mobile information collection, processing and communication units. This network functions as a complex service provider system, with special attention to the on-demand information management in the fuzzy front end of design projects.

AbstractEngineering projects involve the progressive development of preliminary information until a final design is reached. Appreciating its status may help make better decisions about task sequencing and may reduce unnecessary iteration. We present an approach to 1) elicit this maturity, 2) aggregate several of its facets per subsystem and generate insights for task prioritisation, and 3) overlaying this information in Augmented Reality onto a physical prototype. The progress is discussed and it is proposed that the approach can aid understanding, communication and management of design progress.

In Architecture, engineering, and construction (AEC) collaboration, exchange requirements (ERs) vary in different projects with different platforms. In order to ensure the completeness and accuracy of data sharing and exchange for structural engineering in collaborative design, an ER-based delivery method was proposed to improve the delivery of structural design information. First, a process map of structural design was developed based on Information Delivery Manual (IDM). Within this process map, an ER Matrix of structural design was proposed to define information required by other disciplines at different stages. This matrix was composed of a set of required structural objects and their attributes, which were mapped to related Industry Foundation Classes (IFC) data. The mapping between the ER Matrix and IFC-based structural model data was implemented by an exchange model generation algorithm. Furthermore, a delivery tool was developed to define the ER Matrix in two ways, including user interface and XML-based language. A practical project was used to illustrate the utility of the proposed method. The results show that the proposed method using IFC is beneficial for structural information delivery.

Abstract In collaborative design in large organizations, many design tasks are executed concurrently by different groups or departments. Many of these tasks influence each other. Collaborative design can be facilitated by an information system that allows each group to post the status of their respective tasks so that other groups can follow their progress, obtain parameters/specifications required in their own tasks, and avoid conflicts/incompatible solutions. This paper examines the functional requirements for such a Design Information System (DIS), considers alternative solutions, and describes an implementation of such a system. The proposed solution includes a hybrid model for the representation of design information at several levels of formalization and granularity. Both Product Data and Design Procedures (processes) are supported through some common pre-defined design elements (primitives), but the system can be extended to include new user-defined elements. The user interface implementation utilizes the World Wide Web and public domain browsers. The system is currently undergoing field testing in an on-going collaborative design project.
