【摘要】：復(fù)雜產(chǎn)品制造是工業(yè)化的重要組成部分,涉及國防航空、國計民生的方方面面,如衛(wèi)星、導(dǎo)彈、輪船、飛機(jī)、精密儀器和設(shè)備、金融系統(tǒng)等等。在某方面而言,復(fù)雜產(chǎn)品的制造水平直接體現(xiàn)了工業(yè)化的程度。復(fù)雜產(chǎn)品的制造水平又與其制造工藝的設(shè)計、管理密切相關(guān)。制造工藝直接決定復(fù)雜產(chǎn)品的質(zhì)量、生產(chǎn)效率。然而,在國內(nèi)各大企業(yè)里普遍存在著重設(shè)計輕工藝的思想,企業(yè)里對工藝設(shè)計及管理的發(fā)展關(guān)注不夠,以致工藝設(shè)計及管理水平跟國際先進(jìn)水平尚有一定的差距。因此,呼吁企業(yè)重視工藝設(shè)計及管理,提高工藝設(shè)計及管理的水平,是提高復(fù)雜產(chǎn)品制造質(zhì)量的需要,符合企業(yè)和國家發(fā)展的需求。也有越來越多的企業(yè)和專家學(xué)者注意到工藝方面的問題,展開了各種研究。本論文對D公司的復(fù)雜產(chǎn)品裝配工藝管理進(jìn)行優(yōu)化研究,以期能為同類型甚至其他類型企業(yè)的工藝管理提供參考及借鑒。D公司是設(shè)計及生產(chǎn)復(fù)雜產(chǎn)品的國營大公司,在其公司工作實踐中,對其展開的調(diào)查研究中發(fā)現(xiàn)D公司裝配工藝管理的現(xiàn)狀不如人意,存在著種種問題,導(dǎo)致其工藝工作的開展效率低、抱怨多。在對其工藝工作的內(nèi)容進(jìn)行分析及歸納分類后,將其工藝工作內(nèi)容歸類為三大部分:工藝計劃管理、工藝信息管理、裝配現(xiàn)場工藝管理。分別對這三個部分的內(nèi)容進(jìn)行詳細(xì)的現(xiàn)狀調(diào)查。在對工藝計劃管理現(xiàn)狀原因分析時發(fā)現(xiàn)造成其現(xiàn)狀困境的主要原因是工藝計劃管理流程設(shè)置不合理及信息化程度太低,其工藝計劃管理流程周期長,流程效率低。論文基于精益管理思想的指導(dǎo),對其工藝計劃管理流程進(jìn)行優(yōu)化設(shè)置,縮短了其流程周期,提高工作效率。論文運用TRIZ理論中的創(chuàng)新思維方法的九屏幕法對D公司工藝信息管理系統(tǒng)進(jìn)行分析,發(fā)現(xiàn)其工藝信息管理系統(tǒng)存在的最大問題就是信息化程度低。針對此問題,論文使用TRIZ理論中的尋找資源路徑方法在公司內(nèi)外部進(jìn)行資源分析,尋找最優(yōu)方法進(jìn)行優(yōu)化,最后確定引進(jìn)專業(yè)化設(shè)計公司進(jìn)行針對性設(shè)計。設(shè)計出來的計算機(jī)輔助工藝設(shè)計CAPP系統(tǒng)從功能上分析,完全能滿足D公司目前工藝信息管理的需求。論文進(jìn)一步提出可以使用TRIZ理論方法及工具來優(yōu)化CAPP系統(tǒng)在實施過程中遇到的問題。對裝配現(xiàn)場工藝管理的問題,論文使用魚骨圖根本原因分析方法來分析,利用魚骨圖找到三個方面的問題及根本原因。然后論文使用精益管理思想、TOC約束理論思想與TRIZ理論方法和工具相結(jié)合的方法分別對這三個方面進(jìn)行了優(yōu)化。
[Abstract]:The manufacture of complex products is an important part of industrialization, involving national defense aviation, national economy and people's livelihood, such as satellites, missiles, ships, aircraft, precision instruments and equipment, financial systems and so on. In a way, the manufacturing level of complex products directly reflects the degree of industrialization. The manufacturing level of complex products is closely related to the design and management of manufacturing process. Manufacturing process directly determines the quality and production efficiency of complex products. However, the idea of emphasizing design and neglecting technology is common in all the domestic enterprises, and the development of process planning and management is not enough, so there is still a certain gap between the level of process design and management and the international advanced level. Therefore, calling on enterprises to pay attention to process planning and management and improve the level of process planning and management is the need to improve the manufacturing quality of complex products and meet the needs of the development of enterprises and countries. There are more and more enterprises and experts and scholars pay attention to the process of problems, carried out a variety of research. In this paper, the assembly process management of complex products in D Company is optimized, in order to provide reference for the process management of the same type and even other types of enterprises. Company D is a large state-owned company that designs and produces complex products. In the practice of the company, it is found that the present situation of the assembly process management in company D is not satisfactory and there are various problems, which leads to the low efficiency and many complaints of the process work. After analyzing and classifying the contents of the process work, the contents of the process work are classified into three parts: process planning management, process information management and assembly site process management. The contents of these three parts are investigated in detail. It is found that the main reasons for the present predicament of process planning management are the unreasonable setting of process planning management process and the low degree of informatization. The process planning management process cycle is long and the process efficiency is low. Under the guidance of lean management, this paper optimizes the process planning management process, shortens the process cycle and improves the working efficiency. This paper analyzes the process information management system of D Company by using the nine-screen method, which is the innovative thinking method in TRIZ theory, and finds that the biggest problem in the process information management system is the low level of informatization. In order to solve this problem, the paper uses the method of finding resource path in TRIZ theory to analyze the resources inside and outside the company, find the best method to optimize, and finally determine the introduction of specialized design company to carry out targeted design. The computer aided process Planning (CAPP) system can fully meet the needs of D Company's current process information management. The paper further puts forward that TRIZ theory method and tools can be used to optimize the problems encountered in the implementation of CAPP system. For the problem of assembly site process management, the paper uses the method of fish bone chart to analyze the root cause, and uses fish bone diagram to find the three problems and the root cause. Then the paper optimizes the three aspects by using lean management theory, TOC constraint theory and TRIZ theory and tools.
