【摘要】：复杂产品的研制通常会涉及到多个学科和领域,研制周期长,要求投入的资金大,如何使得研制过程高效率、低成本、低风险地进行就成为了一项极具意义的研究。本文拟以航空产品为例,通过对航空产品研制的特点进行分析,设计一套基于技术成熟度的复杂产品研制流程,在保证研制效率的同时控制研制风险,为复杂产品研制过程控制提供新思路。现有的复杂产品研制模式主要以数字化技术和并行协同研制为主体,通过研制流程上下游之间发放的产品数据的成熟度来进行过程控制。这种模式没有对研制中技术的成熟情况做处理,往往由于采用的技术不成熟而导致研制活动存在极大的隐患。基于此,本文的主要工作及创新点有:(1)针对复杂产品研制中由于技术的成熟情况导致可能存在的研制风险,提出以技术成熟度的概念来描述技术在其生命周期中的成熟状态,通过技术成熟度评价的方法确定技术成熟度等级,并根据技术成熟度等级来判断产品研制风险。在技术成熟度评价中提出一种基于粗糙集和信息熵的关键技术要素识别方法,解决传统识别方法过于依赖专家主观意见、需要大量先验知识等不足,缩短技术成熟度评价工作周期,扩展技术成熟度应用范围。(2)将技术成熟度应用到具体的复杂产品研制活动中,提出基于技术成熟度的复杂产品协同研制流程。现有的复杂产品研制中没有广泛应用成熟度来控制研制风险,部分产品也只应用了数模成熟度来对研制活动进行过程控制,本文扩展技术成熟度的应用范围,将其应用到产品研制流程中,制定对应于不同技术成熟度等级的研制活动,构建基于技术成熟度的协同研制流程。(3)设计开发了一个航空产品研制技术成熟度评价管理软件,通过软件实现技术成熟度评价全流程功能和基于技术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.
