Product Family Flexible Design Method Based on Dynamic Requirements Uncertainty Analysis

摘要

Developing product families has been recognized as an efficient and effective means to realize sufficient product variety to satisfy a range of customer and support mass customization manufacturing. This paper presents a product family flexible design method based on dynamic requirements uncertainty analysis. The product family dynamic uncertain requirements analysis and forecasting techniques is researched in this paper, aims to improve the dynamic response ability of the product family to the change of the market demand in the future. Firstly, the multi-domain transmission mode of dynamic requirements was discussed and the product family flexible design model was proposed. Then the sensibility of design parameter to dynamic requirements was analyzed and the variation index of design parameter was calculated. As a result, the product platform of product family flexible design was constructed. A product family flexible design prototype system was also developed, and the application verification for flexible design of forging press product family was carried out to demonstrate the validity of the proposed method.
