Maturity assessment method for scheme of aircraft collaborative design platform

Abstract

The invention discloses a maturity assessment method for the scheme of an aircraft collaborative design platform. The maturity assessment method relates to a research and development requirement-technical characteristic quality house and a fuzzy assessment method. The research and development requirement-technical characteristic quality house of the designed aircraft collaborative design platform comprises a left wall, a ceiling and a room, wherein the left wall is used for describing research and development requirements, the ceiling is used for describing technical characteristics, the room is used for recording a relation matrix between the left wall and the ceiling, and the maturity assessment method is characterized in that an assessment value can be shown through fuzzy section information; the fuzzy assessment method based on group consistency strength converts fuzzy section assessment information into the determined assessment value through a semantic discount factor, the problem of processing fuzzy and lost information in an assessment process can be solved, and assessment subjectivity can be lowered. The maturity assessment method can solve the problems of index design, description and integration of fuzzy assessment information, and the like in the assessment process, and provides a novel idea for quality assurance and process control in aircraft collaborative design.

Description

technical field [0001] The invention belongs to the field of aircraft digital design and the field of computer-supported collaborative design, in particular to a scheme maturity evaluation method for an aircraft collaborative design platform. Background technique [0002] Because the aircraft design process is very complicated, the cycle is long, and the input cost is high, digital collaborative design technology has become a research hotspot in recent years. The development of digital collaborative design technology provides a new method for the design of new aircraft. [0003] The aircraft collaborative design platform provides designers with a digital platform, enabling professionals from various disciplines to design collaboratively and discover design conflicts in time, thereby improving design efficiency and quality, and reducing design costs. However, in the development process of the aircraft collaborative design platform, since personnel with different professional ...

Problems solved by technology

[0005] However, the above methods still have the following shortcomings: 1) The collaborative design of aircraft involves multiple professional disciplines, but the existing index system does not reflect the professional and quality requirements of each discipline; 2) The maturity assessment of the platform design scheme involves multiple disciplines. Professionals in the discipline, due to the particularity of the field, it is difficult for evaluators to make accurate evaluations of indicators that are not their own majors; 3) After evidence fusion, only qualitative evaluation grades or intervals can be given, and quantitative evaluations cannot be given value
