【摘要】：復雜產品的研制通常會涉及到多個學科和領域,研制周期長,要求投入的資金大,如何使得研制過程高效率、低成本、低風險地進行就成為了一項極具意義的研究。本文擬以航空產品為例,通過對航空產品研制的特點進行分析,設計一套基于技術成熟度的復雜產品研制流程,在保證研制效率的同時控制研制風險,為復雜產品研制過程控制提供新思路�，F(xiàn)有的復雜產品研制模式主要以數(shù)字化技術和并行協(xié)同研制為主體,通過研制流程上下游之間發(fā)放的產品數(shù)據(jù)的成熟度來進行過程控制。這種模式沒有對研制中技術的成熟情況做處理,往往由于采用的技術不成熟而導致研制活動存在極大的隱患。基于此,本文的主要工作及創(chuàng)新點有:(1)針對復雜產品研制中由于技術的成熟情況導致可能存在的研制風險,提出以技術成熟度的概念來描述技術在其生命周期中的成熟狀態(tài),通過技術成熟度評價的方法確定技術成熟度等級,并根據(jù)技術成熟度等級來判斷產品研制風險。在技術成熟度評價中提出一種基于粗糙集和信息熵的關鍵技術要素識別方法,解決傳統(tǒng)識別方法過于依賴專家主觀意見、需要大量先驗知識等不足,縮短技術成熟度評價工作周期,擴展技術成熟度應用范圍。(2)將技術成熟度應用到具體的復雜產品研制活動中,提出基于技術成熟度的復雜產品協(xié)同研制流程。現(xiàn)有的復雜產品研制中沒有廣泛應用成熟度來控制研制風險,部分產品也只應用了數(shù)模成熟度來對研制活動進行過程控制,本文擴展技術成熟度的應用范圍,將其應用到產品研制流程中,制定對應于不同技術成熟度等級的研制活動,構建基于技術成熟度的協(xié)同研制流程。(3)設計開發(fā)了一個航空產品研制技術成熟度評價管理軟件,通過軟件實現(xiàn)技術成熟度評價全流程功能和基于技術成熟度的研制流程控制。
[Abstract]:The development of complex products usually involves many disciplines and fields. The development cycle is long and the investment is large. How to make the development process efficient, low cost and low risk has become a very meaningful research. This paper takes aeronautical products as an example, through analyzing the characteristics of aviation product development, designs a set of complex product development process based on technology maturity, which can guarantee the development efficiency and control the development risk. It provides a new idea for complex product development process control. The existing complex product development model is mainly composed of digital technology and parallel collaborative development. The process control is carried out through the maturity of the product data distributed between upstream and downstream of the development process. This model does not deal with the maturation of the technology in development, which often leads to great hidden trouble in the research and development activities due to the immaturity of the adopted technology. Based on this, the main work and innovation of this paper are as follows: (1) aiming at the possible development risk caused by technology maturity in complex product development, the concept of technology maturity is proposed to describe the mature state of technology in its life cycle. The technology maturity grade is determined by the technology maturity evaluation method, and the product development risk is judged according to the technology maturity grade. In the technology maturity evaluation, a method based on rough set and information entropy is proposed to identify the key technical elements, which solves the shortcomings of traditional recognition methods, such as relying too much on the subjective opinions of experts and requiring a large amount of prior knowledge. The technology maturity evaluation work cycle is shortened and the application scope of technology maturity is expanded. (2) the technology maturity is applied to specific complex product development activities and the collaborative development process of complex product based on technology maturity is put forward. There is no extensive application maturity to control the development risk in the existing complex product development, and some products only use the digital model maturity to control the process of development activities. In this paper, the application scope of technology maturity is expanded. It is applied to the process of product development, and the research activities corresponding to different technology maturity levels are worked out, and the collaborative development process based on technological maturity is constructed. (3) A software for evaluating and managing the technological maturity of aviation product development is designed and developed. The whole process function of technology maturity evaluation and development process control based on technology maturity are realized by software.
