Aiming at the certification process of airborne system AE653/Cert,the modeling method and principle of requirement acquisition process are firstly annotated.

Based on the problems that exist in the course of equipment requirement acquisition and analysis,such as repeated work and experience being hard to use for reference,an idea is proposed that a general model which takes armored equipment type requirement as object is created to aid the work of requirement acquisition and analysis.

The requirements elicitation of application software is tightly involved with the application domain and faced with many non-technological issues.

Compared with the available approaches for requirements elicitation, the approach presented in the paper .

Requirements Engineering (RE) is a branch of Software Engineering, whose activities involve requirements elicitation, requirements analysis, requirements specification, requirements validation and requirements management.

Method for Requirement Acquirement Based on Domain Model;

With more and more research on software engineering, software requirement is becoming the core fact which runs through the whole process of the development of the software, and the requirement acquirement has become the new hot spot of software engineering.

Research of Software Requirement Elicitation on Information System;

The Research and Design of UML-Based Requirement Elicitation Tool;

On the basis of researches on requirement product configuration in Mass Customization,the concepts of product family requirement class(PFRC) and requirement matching template were put forward,and a case-based requirement-product-configuration(CB-RPC) model and a corresponding requirement product model were presented.
