The requirements designing—house of quality is designed to evaluate the maturity degree of the solution, and the evaluation results can help to manage and control the development process. Furthermore, a fuzzy evaluation method based on the minimum deviation is proposed to deal with the fuzzy information. The quantitative evaluation result of the maturity degree can be calculated by optimizing the semantic discount factor aim for the minimum deviation. Finally, this model is illustrated and analyzed by an example study of the aircraft collaborative design software.展开更多

Using these technologies, a model of architecture-centric software analysis and design process（ACSADP） is proposed. Meanwhile, with regard to the completeness, consistency and correctness between the software requirements and design results, the theories of function and process control are applied to ACSADP. Finally, a model of integrated development environnment （IDE） for ACSADP is propcsed. It can be demonstrated by the practice that the model of ACSADP can aid developer to manage software process effectively and improve the quality of software analysis and design.展开更多
