【摘要】：航天電子產(chǎn)品制造項目屬于航天項目全壽命周期中的一部分,主要依據(jù)設(shè)計方案,利用工藝手段進行產(chǎn)品實現(xiàn)的過程,具有投入資金多,技術(shù)面廣,生產(chǎn)周期長,可靠性要求高等特點。項目的風(fēng)險因素眾多,一個因素考慮不周便會導(dǎo)致項目的生產(chǎn)進度、成本、性能指標受到影響,甚至導(dǎo)致整個項目失敗,造成巨大損失,因此在航天項目的生產(chǎn)制造領(lǐng)域加強風(fēng)險評價工作,提高風(fēng)險管理水平勢在必行。 本文借助航天電子產(chǎn)品生產(chǎn)制造的實例,探討基于失效模式與影響分析(Failure Mode and Effects Analysis, FMEA)的綜合風(fēng)險評價方法以及模糊層次分析法(Fuzzy Analytic Hierarchy Process, Fuzzy AHP)在應(yīng)用。目前完成的主要工作如下： (1)航天電子產(chǎn)品制造風(fēng)險分析 明確航天電子產(chǎn)品制造的基本概念,深入分析制造過程存在的風(fēng)險名稱、類型；以及探討航天型號技術(shù)風(fēng)險所用到的風(fēng)險評價技術(shù)。 (2)基于FMEA的風(fēng)險評價技術(shù) 深入探討FMEA結(jié)合FTA、專家調(diào)查法的綜合風(fēng)險評價方法,提出FTA對風(fēng)險進行識別,確定FMEA的失效模式以及失效原因(機理),借助專家調(diào)查法對識別出的風(fēng)險進行評估,即對FMEA過程中的嚴重度、發(fā)生度、檢測度進行定性分析,從而獲取風(fēng)險度； 針對多層級風(fēng)險因素,基于FMEA分析中的嚴重度、發(fā)生度、檢測度三項評估因素,利用Fuzzy AHP對專家調(diào)查結(jié)果進行風(fēng)險評價,從而獲取風(fēng)險排序。 (3)案例分析 在上述探討的風(fēng)險評價技術(shù)基礎(chǔ)上,針對兩種不同的風(fēng)險管控類型,進行實例驗證。 運用上述風(fēng)險評價技術(shù),可提高航天電子產(chǎn)品制造領(lǐng)域風(fēng)險評價技術(shù)手段的科學(xué)性,為決策人員提供更準確的風(fēng)險因素信息,為制定并執(zhí)行風(fēng)險計劃提供更為合理的依據(jù)。
[Abstract]:The aerospace electronic product manufacturing project is a part of the whole life cycle of the space project. It is mainly based on the design scheme and the process of product realization by means of technology. It has many investment, wide technical scope and long production cycle. High reliability requirements and other characteristics. There are many risk factors in the project. If one factor is not considered properly, the production schedule, cost and performance index of the project will be affected, and even the whole project will fail, resulting in huge losses. Therefore, it is imperative to strengthen the risk evaluation and improve the risk management level in the field of production and manufacturing of aerospace projects. This paper discusses the comprehensive risk assessment method based on failure mode and impact analysis (Failure Mode and Effects Analysis, FMEA) and the application of fuzzy analytic hierarchy process (Fuzzy Analytic Hierarchy Process, Fuzzy AHP) in aerospace electronics manufacturing. The main work accomplished at present is as follows: (1) risk analysis of aerospace electronic product manufacturing clarifies the basic concept of aerospace electronic product manufacturing, deeply analyzes the name and type of risk existing in manufacturing process; This paper also discusses the risk assessment technology used in aerospace technology. (2) the risk assessment technology based on FMEA is deeply discussed in FMEA combined with the FTA, expert investigation method, and the identification of the risk by FTA is put forward. The failure mode and failure reason (mechanism) of FMEA are determined, and the identified risk is evaluated by expert investigation method, that is, the severity, occurrence degree and detection degree of FMEA process are qualitatively analyzed, and the risk degree is obtained. Aiming at multi-level risk factors, based on the three evaluation factors of severity, occurrence and detection in FMEA analysis, Fuzzy AHP is used to evaluate the risk of the results of expert investigation. In order to obtain risk ranking. (3) case study on the basis of the risk assessment technology discussed above, for two different types of risk management and control, a case study. The application of the above risk assessment technology can improve the scientific nature of the technical means of risk assessment in the field of aerospace electronics manufacturing, provide more accurate information of risk factors for decision makers, and provide more reasonable basis for making and implementing risk plans.
