The development of a collaborative design chain reference model for the motorcycle industry

A well-defined and flexible design chain reference model forms the basis for promoting collaborative design chain. The Special Interest Group under the Design Chain Council proposed the design chain operations reference (DCOR) in an attempt to assist enterprises building a design chain modeling frameworks. To date, DCOR version 1.0 only provides preliminary definitions, such as those for major design procedures, and lacks an example of best practices in the industry. Additionally, few studies have attempted this research issue. This study integrates the concepts of design chain, collaborative product design, and collaborative product commerce in a proposed collaborative design chain operations reference model (CDCORM) based on DCOR as a reference for developing a collaborative design chain system in the product lifecycle. The CDCORM consists of four hierarchical levels: collaborative design chain business model; collaborative design chain cooperative model; collaborative design-chain process model; and, a collaborative design chain operational model. Based on project management, the CDCORM has five core procedures-product plan, concept design, detail design, design review, and design amend. This study also assesses the effectiveness of the CDCORM by applying it to the motorcycle industry. In summary, this study extends the DCOR model and proposes a complete collaborative design chain reference model and implements a system in the motorcycle industry as a case study. This case study serves as a best practices example for the motorcycle industry.

A design representation scheme for collaborative product development

Design is an integral component of product development, which includes manufacturing. In order to avoid costly reworks and delays, and to reduce the lead-time in product development, effective communication of design concepts among the various stakeholders such as customers, designers and engineers is of utmost importance. In this respect, functional representations provide a methodology, which can be used to describe a design or product effectively. However, function is not the only type of information that needs to be communicated among the various stakeholders during a design process. Other types of information such as design specifications and constraints, which are non-functional, also need to be taken into account. This non-functional information cannot be adequately expressed using existing functional representations. Accordingly, in this work, a novel purpose-behaviour-structure (PBS) representation scheme to capture vital design knowledge for collaborative product development is proposed. The proposed PBS representation scheme can be used by designers working in a collaborative environment for product development. A case study on the design of a vacuum cleaner is used to illustrate the functionality of the PBS representation scheme. The details of the representation scheme are presented in this paper.

An object-oriented conceptual model of a collaborative product development management (CPDM) system

It is apparent that the development or implementation of a collaborative product development management (CPDM) system in an enterprise should be based on the right understanding of core domain objects, their main attributes, and their relationships to other objects in the product development domain. For this purpose, an object-oriented conceptual model of a CPDM system based on a top-down approach is presented in this paper. For building the conceptual model systematically, this paper proposes the 4P2C modeling views, which are multi-faceted views of engineering information that provides an integrated and consistent perspective on engineering information. The 4P2C stands for product, process, project, participant, cost, and collaboration. Based on the 4P2C modeling views, six sub-models are constructed that eventually constitute a complete conceptual CPDM model. In each sub-model, the decomposition of core domain objects, their main attributes, and their relationships to other objects are represented in detail. A prototype application program along with an illustrative cost calculation example is also presented to demonstrate that the proposed CPDM model will enable enterprises to maintain consistency in product data efficiently throughout the product life cycle.

An asynchronous and synchronous coupling approach in networked rapid product development

Faced with today's competitive market, the development of innovative product needs to be accelerated. But this is limited by heterogeneous systems and a distributed environment. A way of utilising network technology to this end must be found. In this paper, we use a new approach, called asynchronous and synchronous coupling, which is a network-based product development approach. This is then applied to rapid-response manufacturing by small- and medium-sized enterprises in a distributed environment. It demonstrates integrated thinking, high development speed and a transparent development process. Visual technology and real-time monitoring technology are used to solve asynchronous process and data management problems. An ICE (integrated collaborative environment) is also created to support synchronous collaboration.

Decentralised production-distribution planning system using collaborative agents in supply chain network

With the fast development of information technology and the global market, collaboration between different functional units in a supply chain becomes one of the most critical factors for global companies to respond to rapid changes in customer needs and increase the efficiency of the whole supply chain. This supply chain environment requires a production-distribution planning system to enable the collaboration between production and distribution units more quickly and orderly. Generally, collaboration in a supply chain needs to resolve conflicts between two decentralised functional units, because each unit tries to locally minimise its own costs, not the overall supply chain costs. Also, there exists incomplete information sharing according to the information privacy of each functional unit. This paper proposes a decentralised production-distribution planning system using collaborative agents that can efficiently mediate the planning gaps between two decentralised planning functions: production and distribution. The validity of collaborative-agent model has been shown using some lemmas and numerical examples.
