Product family design entails all of the challenges of product design while adding the complexity of coordinating the design of multiple products in an effort to maximize commonality across a set of products without compromising their individual performance. This paper presents the Variation-Based Platform Design Method (VBPDM) for product family design, which aims to satisfy a range of performance requirements using the smallest variation of the product designs in the family. In the first stage of the VBPDM, the product platform around which the product family is to be developed is identified. The product platform is common to all of the products in the family and represents the maximum standardization possible considering the variety of performance requirements that must be satisfied. To satisfy the range of performance requirements for the product family, a ranged set of solutions is found using variation-based modeling. A compromise Decision Support Problem (DSP) is formulated to solve the tradeoff between satisfying the variety requirement and maximizing platform commonality. Platform commonality is achieved by introducing a commonality goal that seeks to minimize the deviation of the input design variables while satisfying the range of performance requirements. Those design variables that show small deviations are held constant to form the product platform. In the second stage of the VBPDM, each individual product is designed around the common platform such that the functional requirements for each product in the family are best satisfied. As an example, the proposed method is used to develop a family of universal electric motors designed to meet a range of torque requirements. The results are compared against previous work on the same example. 相似文献

Design for variety: developing standardized and modularized product platform architectures 总被引:26,自引:5,他引:26
Developing a robust, product platform architecture brings an important competitive advantage to a company. The major benefits
are reduced design effort and time-to-market for future generations of the product. This paper describes a step-by-step method
that aids companies in developing such product platform architectures. Using the concept of specification "flows" within a
product development project, the design for variety (DFV) method develops two indices to measure a product's architecture.
The first index is the generational variety index (GVI), a measure for the amount of redesign effort required for future designs
of the product. The second index is the coupling index (CI), a measure of the coupling among the product components. The design
team uses these two indices to develop a decoupled architecture that requires less design effort for follow-on products. This
paper describes the DFV method and uses a water cooler example to illustrate the method.

Customer Value Chain Analysis 总被引:1,自引:2,他引:1
Krista M. Donaldson Kosuke Ishii Sheri D. Sheppard 《Research in Engineering Design》2006,16(4):174-183
Customer Value Chain Analysis (CVCA) is an original methodological tool that enables design teams in the product definition phase to comprehensively identify pertinent stakeholders, their relationships with each other, and their role in the product’s life cycle. By performing CVCA, design teams are better able to recognize diverse product requirements and their relative priority when undertaking Product Definition Assessment and using downstream ‘Design for X’ (DfX) tools. This paper discusses the evolution of the CVCA in response to the need for a DfX tool which is able to delineate customer needs early in the product development process. A step-by-step guide clarifies the implementation of CVCA with an example. Three case studies highlight the tool’s broad utility and important features to support design decision making, including: (1) confirmation of the product’s business model, (2) recognition of the critical stakeholders, and (3) clarification of the value proposition to be embedded in the product.
