Abstract: During using QFD (Quality function deployment) to make decision on product planning, it is the ultimate aim to determine the targets of the technical characteristics satisfying customer requirements in order to guide the product developing based on the information in the HOQ (House of quality). But most of the existing planning models cannot directly give the target values of technical characteristics, and do not consider the different types of technical characteristics： discrete type and continuous type, which cannot reflect the situations effectively. Taking advantage of the information in HOQ fully and consider the technical characteristics with discrete type and continuous type distinguishably, an optimization model is presented, and an example is given.

Key words: HOQ, Optimization model, Technical characteristic of discrete type
