This paper extends the previous work in which two QFD models, a "2-storied quality chart" and a "Parallel flow quality chart," were proposed as tools for concurrent engineering product development driven by a matrix organization. This paper compares these two models with two real cases from a...
This paper presents a new approach for integrating downstream activities of forged part design in a concurrent engineering con text. We show how a CAD application, integrating specific know-how, can enable co-design between the different actors involved. We develop two dimensions of activity,...
Coordination is a crucial problem in CE systems and it is neither easy to obtain nor to maintain. Our work is an attempt to develop a general model for coordination which can be adapted for some situations in the context of CE. For this purpose, the coordination definition developed by Malone 25...
This paper presents the implementation of the algorithms used to compute the die-open directions for a near-net-shape manufac tured part described in "Virtual Prototyping of Die Design Part One. Theory and Formulation." In this approach, a set of concavity features is used to determine the...
The current research uses a computer-based approach to automatically determine the set of possible die-open directions for a given part. We have ascertained that certain features on a part, called concavity features, restrict the directions in which a die may be opened. Therefore, the current...
This paper revolutionizes the design of process tolerances, and proposes a nonlinear programming model that utilizes the cumu lative standard normal probability function to estimate the scrap rate of the operations and the entire process. The process capability of the equipment is formulated to...
This paper reports the development of a collaborative product development environment using multi-disciplinary analysis and de sign (MAD) technology and the information infrastructure of the WWW/Internet. The proposed product development environment provides a two level hierarchical setup for...
