Firstly, quality characteristics (QCs) are defined, the three-layer model and technical connotation of quality characteristics are presented, then the concept of key quality characteristics (KQCs) is presented and its evolution process model is created, and the key activities of KQCs evolution are discussed in the context of design for quality (DFQ).

A Study of Automated Cartographic Generalization Based on Design for Quality;

quality conversion equally in design for quality.

In quality engineering there are three important subjects which are computer aided integrated tolerancing, design for quality, and dynamic quality control of small batch production.

Association rule mining algorithm in modeling quality activity chain based on quality cost data;

After analyzing the drawbacks of the traditional analysis of quality cost, the paper reviews the whole realization process of products and introduces the concept of quality activity chain.

Research on Subjects and Activities Design for Tele-Collaborative Learning Project by Elementary School;

This paper shows the importance of activities design in open and distance learning materials and intro- duces the types of activities and how to create and arrange them.

According to the characteristics of ship design,this paper put forward a method which divided ship design process into three layers as project,design task and design activity,then present the formalized definitions of the ship design process model,the decomposing principles of the ship design process and the architecture of the ship cooperative design system.

According to the characteristics of the ship design, a discomposed method for the ship design process from three layers: proj ect, design task and design activity is put forward and a formal Ship Design Pr ocess Model(SDPM) is given out.

In concurrent engineering, the overlap between the upstream product design activity and the downstream process design activity can shorten the duration of the product development process.
