This paper presents a design reuse methodology to facilitate product family design. Three major processes are defined, namely, information modelling, information processing, and solution synthesis and evaluation. The information content assessment (ICA) method is proposed for solution evaluation. This method defines logical steps to compute the information content that is used as a uniform, dimensionless metric of product performances. In a case study, product families of the cellular phone were developed using the design reuse methodology. It is demonstrated that the design reuse method proposed in this paper can effectively manage the product family design processes, and the ICA method provides a useful way for performance evaluation. 相似文献

Due to the rapid progress of technology and severe competition in market, recent industrial products are required to exhibit high quality and functionality. At the same time products are required to be environmentally conscious. Therefore it is important to achieve appropriate product reliability with minimum resource consumption. In the total product lifecycle there exist various kinds of disturbances which may deteriorate product quality and functionality. A reliability design method is proposed based on prediction of product behaviour deterioration and its influence on product functional failure. Effectiveness of the proposed method is evaluated by mechatronics product design. 相似文献

Product variety is required for satisfying customer needs, and at the same time, efficient usage of manufacturing resources is mandatory for competitive and environmentally conscious manufacturing. For coping with these requirements, product family concept is effective, which enables variety of products based on well designed similar product property with associated manufacturing processes. In this study, a modeling framework for relationship between product functionality and manufacturing resources is discussed. Based on this framework, a design method is investigated for product family structure which realizes required product functional variety with efficient utilization of manufacturing resources. Application examples are discussed for automotive components. 相似文献

产品设计质量综合评价的理论研究 总被引:2,自引:0,他引:2
袁清琦 《组合机床与自动化加工技术》1998,(5):35-38
随着市场竞争的加剧和各种先进技术的应用,尤其是并行工程和产品并行设计技术的应用,产品设计质量已不再用是否满足设计任务书中规定的性能指标来衡量,而是从市场/用户、技术、经济、环境等多个方面来评价产品设计质量的优劣。本文提出了产品设计质量综合评价理论与体系,从而实现了从多方位、多层次对产品设计质量的全面综合评价 相似文献

Based on earlier work on risk quantification, a new risk mitigation methodology is developed for new product and process design in concurrent engineering projects. First the most prominent risks in the product life cycle are identified and quantified. Then five computational algorithms are developed and used to find feasible solutions for mitigating these risks: Least-Cost-First, Highest-Risk-First, Minimum-Cost-Risk-Ratio- First, Random-Search and a Genetic Algorithm. Based on the available mitigation budget and strategic objectives of the project the best mitigation strategy is then recommended to the project managers. Actual financial outcomes of an industry project were used to successfully validate the methodology. 相似文献
