Requirement Acquisition Method of Product Life cycle Based on HLDA Hierarchy Model under the Background of Web Technology

Abstract Product requirement is the goal of product development and design activities, which originates from all stages of product life cycle. In the process of acquiring product requirements, there are some problems such as incomplete mining of product requirements and fuzzy structural expression. In view of the above problems, this paper proposes a product life cycle requirements acquisition method based on axiomatic design. Firstly, web technology is applied to collect requirements information, and based on HLDA hierarchy model, the requirements information is classified according to the whole life cycle stages of products; then, the product requirements mining model based on axiomatic design is established to mine the requirements of the whole product life cycle; finally, the product requirements model tree is structured and the product life cycle requirement model is established; This paper takes shield machine segment erector as an example to verify the effectiveness of the proposed product life cycle requirements acquisition method.
