The recent advance in information technologies has the potential to greatly enhance product development, and to make distributed designers, engineers, manufacturers and customers work together over networks. This paper reviews related work on service-oriented architecture, distributed infrastructure and highlights the need to integrate service-oriented architecture technologies for meaningful and interactive collaborative design processes. This paper presents a service-oriented architecture implemented by web services for collaborative design. The collaborative workspace is presented to facilitate the design participants’ collaboration. The proposed architecture is applicable to different requirements of design participants and enhances design interaction during the product realization process.
Product design is a multi-perspective group decision making process which has the different viewpoints together to create the solutions among stakeholders. In product design process, every stakeholder has his/her own subjective characteristics and variable perspectives which reflect his/her understandings of design objects. The perspective relationships between stakeholders will directly influence the speed of achieving solutions, which in turn affect design time and efficiency. By analyzing the similarity relationships between the participants' perspectives, this paper constructs perspective network model and applies structure matrix to develop perspective relationships. This paper focuses on incorporating perspectives into design process and developing the approaches to make decisions support for the optimal design solutions considering stakeholders’ perspectives. Finally, an example is used to demonstrate that perspective network model can analyze the impacts of perspectives on the solution.
Collaborative product design is a complex and time-consuming process whereby geographically distributed designers from different disciplines cooperate and collaborate. Well-studied collaborative product design system reduces development time and creates better products. This paper discusses the characteristics of collaborative product design based on multi-agent technology to minimize the development time, cost and risk. In particular, the proposed agents can provide the interaction spaces for coordinating the individual design activities. Furthermore, the mechanism of intercommunications between agents is discussed. This research work constitutes initial effort towards optimization of process of collaborative product design. Future effort will focus on the software implementation of the theory presented in this paper.
Collaborative product design is a multiple criteria group decision making process bringing different and often controversial points of view together to create a solution among stakeholders. Collaborative design possesses more perspectives than any single person possesses because stakeholders have different perspectives. This work is based on new decision approach that includes creating shared understanding among various stakeholders, contextualizing design criteria and perspectives, and creating a multiple perspective and multiple criteria decision approach, our initial effort has focused on incorporating perspectives into design process. We then provide the approach to find the optimal design decisions for consideration of stakeholders’ perspectives. By analyzing the relationships between stakeholders’ perspectives and preferences of design criteria, multi-criteria decision making approach considering the stakeholders’ perspectives can be used to monitor and control the collaborative design process.
