In today’s global economy, companies develop products not only to target a single market, but to sell them to the entire world. Companies that realize the importance of collaborative design develop regional engineering centers worldwide to balance design variations while ensuring local market success. This paradigm enables diverse customer values to be integrated into products, but also introduces challenges in the management of work distribution. Typically, workshare decisions consider the capability and capacity of the regional centers. This strategy, however, overlooks the interdependence of the design systems, leading to delays and quality problems. This paper describes a method to formulate the workshare risk based on the couplings of the design system components and to evaluate overall workshare scenario. The method involves two relationships, Component-to-Component Coupling and Workshare Coupling, and a technique to combine these two relationships to measure the workshare risk. A simple case of hair dryer illustrates the concepts, while the method is serving actual global automotive development projects.

Global companies realize the importance of collaborative design, or workshare, to develop products not only to target to a single market, but to sell them to the entire world. Workshare not only incorporates diverse customer values into the product development, but also introduces challenges in managing work distributions among global teams. As a result, the authors have developed a Distributed Risk Framework to quantify risk based on rework to facilitate workshare planning [5] [6]. The risk framework has been applied to several industry projects and it received positive feedback from the potential users of these pilot applications. To verify the risk results analytically, this paper seeks for statistical evidence to confirm the key assumption that motivates the development and the usage of the framework, with the assumption being that more distributed work results in a greater risk of rework. This paper begins with an overview of the risk framework followed by the steps of using actual rework data from the International Vehicle Company (IVC) to confirm the framework assumption. As a summary, this paper presents the contributions of the risk framework and the barriers to extend it to other distributed product development projects.

Work Distribution

Under the current trend of globalization, companies develop products not only to target a single market but to sell them to the entire world. Companies realize the importance of collaborative design, or workshare, to develop global regional engineering centers to balance design variations while ensuring local market success. This paradigm shift enables diverse customer values to be integrated into products but also introduces challenges in the management of work distribution. Extensive industry case studies have shown that capability and capacity of the regional centers drive the workshare decisions; however, this strategy overlooks the interdependence of the design systems causing many delays and quality problems. Seeing the opportunity, this paper presents a method to identify and to quantify the system-level workshare risk based on the couplings of system components to evaluate the overall workshare scenarios. The risk analysis consists of two key elements in terms of two relationships, the division of work for distributions (i.e., component coupling) and the work assignments of the distributed teams (i.e., workshare coupling), as well as an algorithm to combine the relationships to calculate the workshare risk. To illustrate the steps of the risk analysis, this paper applies it to a hair dryer design as a case study. The paper also discusses the usages and characteristics of the risk analysis, and concludes with the future research and the next steps of generalizing the method to other product development projects.

Tools and applications are needed to provide engineers with support to design in a distributed and collaborative environment. These systems and tools need to make it possible to share design information, and schedule design process so that a group of distributed engineers can work together. Software level design is the prerequisite condition for applying any design approaches into the distributed mechanical design and in this paper, basic design systems and design tools are developed so that a typical distributed mechanical design can be supported. Requirements for a collaborative design system are presented, along with requirements to develop a prototype distributed system. The system is demonstrated on reverse engineering project for an aircraft component.

New and efficient paradigms for web-based collaborative product design in a global economy will be driven by increased outsourcing, increased competition, and pressures to reduce product development time. We have developed a three-tier (client-server-database) architecture based collaborative shape design system, Computer Aided Distributed Design and Collaboration (CADDAC). CADDAC has a centralized geometry kernel and constraint solver. The server-side provides support for solid modeling, constraint solving operations, data management, and synchronization of clients. The client-side performs real-time creation, modification, and deletion of geometry over the network. In order to keep the clients thin, many computationally intensive operations are performed at the server. Only the graphics rendering pipeline operations are performed at the client-side. A key contribution of this work is a flexible architecture that decouples Application Data (Model), Controllers, Viewers, and Collaboration. This decoupling allows new feature development to be modular and easy to develop and manage.

Abstract This paper gives an overview of a collaborative design system (CDS) for electromechanical products. To reduce design costs and to manufacture high-quality products, it is well known that concurrent engineering (CE) is a very efficient approach. Three-dimensional (3D) CAD system and engineering database system are essential components of CE. The CDS is an environment to realize CE. By creating 3D models in a computer and performing some simulations such as mechanical, electronic, software simulation and integrated simulations, it is possible to estimate functions, assemblability, manufacturability and so on, before making prototype models. In this paper, we outline the CDS and mainly discuss the total information management system (TIMS) which makes an important role of the CDS. This paper describes the implementation experience of some functions of the TIMS.

Blade Geometry

A CAD-centric approach for constructing and managing the blade geometry in turbomachinery aero design systems is presented in this paper. Central to the approach are a flexible CAD-based parametric blade model definition and a set of CAD-neutral interfaces which enable construction and manipulation of the blade solid model directly inside the CAD system’s geometry kernel. A bottleneck of transferring geometry data passively via a file-based method is thus eliminated, and a seamless integration between the CAD system, aero design system, and the larger design environment can be achieved. A single consistent CAD-based blade model is available at all stages of the aero design process, forming the basis for coupling the aero design system to the larger multi-disciplinary design environment. The blade model construction is fully parameterized so that geometry updates can be accurately controlled via parameter changes, and geometric sensitivities of the model can be easily calculated for multidisciplinary interaction and design optimization. A clear separation of the parameters that control the three-dimensional shape of the blade (such as lean and sweep) from the parameters that control the elemental profile shape allows any blade profile family or shape definition to be utilized. The blade model definition, construction interface, and implementation approach are described. Applications illustrating solid model construction, parametric modification and sensitivity calculation, which are key requirements for automated aerodynamic shape design, are presented.
