【摘要】：第二次世界大戰(zhàn)以后,日本豐田汽車企業(yè)通過使用精益生產(chǎn)方式來不斷提高市場競爭力。20世紀70年代后期,歐美國家和日本企業(yè)開始全面使用精益生產(chǎn)管理模式,逐漸形成了十分獨特的精益生產(chǎn)文化,精益生產(chǎn)為這些企業(yè)帶來巨大的市場競爭力,成就了許多大型跨國企業(yè)。我國早在二十世紀八十年代就開始,一些大型企業(yè)就開始引進了精益生產(chǎn),期待借鑒外部先進的經(jīng)驗和管理方法解決生產(chǎn)中存在的問題,但在實際操作過程中由于受到企業(yè)文化、管理體制、員工素質(zhì)等多方面因素限制,發(fā)現(xiàn)難以獲得成功。近幾年隨著外資企業(yè)的增多,國內(nèi)的一些優(yōu)秀企業(yè)通過交流學(xué)習(xí),正在不斷摸索適合自己的精益生產(chǎn)模式。本文結(jié)合W公司螺桿式壓縮機實際生產(chǎn)狀況,通過價值流分析方法,利用價值流圖對企業(yè)生產(chǎn)流程中各個環(huán)節(jié)進行分析,查找企業(yè)各個生產(chǎn)環(huán)節(jié)中存在得浪費原因,研究如何運用精益生產(chǎn)理論指導(dǎo)企業(yè)優(yōu)化現(xiàn)有的螺桿式壓縮機生產(chǎn)線。分析W公司螺桿式壓縮機生產(chǎn)線存在的問題,提出優(yōu)化方案,幫組企業(yè)改善生產(chǎn)狀態(tài)。文章首先介紹選題背景及意義,對精益生產(chǎn)理論及價值流分析法進行簡要的介紹。利用價值圖分析方法對W公司螺桿式壓縮機的生產(chǎn)裝配線進行全面解析,繪制價值流圖。通過分析當前價值流圖發(fā)現(xiàn)生產(chǎn)制造系統(tǒng)的需要改善的環(huán)節(jié)。根據(jù)W企業(yè)2017年螺桿式壓縮機銷售預(yù)測和最新發(fā)展規(guī)劃,以精益生產(chǎn)理論為指導(dǎo),為W公司設(shè)計螺桿式壓縮機生產(chǎn)的最新價值流圖,研究制定螺桿式壓縮機生產(chǎn)制造系統(tǒng)優(yōu)化方案,設(shè)計出符合現(xiàn)實意義的生產(chǎn)制造系統(tǒng),并組織實施。課題研究的過程中,筆者基于客戶不同的需求,對螺桿桿式壓縮機生產(chǎn)系統(tǒng)產(chǎn)能以及在線庫存等問題進行了詳細的分析和闡述。利用詳細數(shù)據(jù)進行計算,對實施精益生產(chǎn)后桿式壓縮機生產(chǎn)的各個指標進行了詳細的論證,指出了精益生產(chǎn)方式本身所具有的優(yōu)勢。目前,越來越多的企業(yè)已經(jīng)認識到精益生產(chǎn)理論對企業(yè)發(fā)展具有的現(xiàn)實意義,嘗試利用精益理論來優(yōu)化企業(yè)生產(chǎn),期待取得成功。但是對于企業(yè)來說,必須認識到精益生產(chǎn)方式并不是通過一次生產(chǎn)線的優(yōu)化就可以達到的,精益生產(chǎn)實際上是一個持續(xù)改善,追求盡善盡美的過程。只有在分析-改善-再分析-再改善的過程中,不斷地消除浪費,研究摸索符合企業(yè)自身的生產(chǎn)方式,企業(yè)才會在不斷完善中發(fā)展壯大。精益理論雖然時一種外來理論,但是隨著在各行各業(yè)應(yīng)用的增多,它也一定會在中國得到豐富和升華,為中國企業(yè)發(fā)展壯大發(fā)揮巨大的作用。
[Abstract]:After the second World War, Toyota automobile enterprises in Japan used lean production methods to continuously improve their market competitiveness. In the late 1970s, European and American countries and Japanese enterprises began to use lean production management mode in an all-round way. Gradually formed a very unique lean production culture, lean production for these enterprises to bring huge market competitiveness, has achieved many large multinational enterprises. As early as the 1980s, some large enterprises in China began to introduce lean production, hoping to learn from advanced external experience and management methods to solve the problems in production. However, due to the limitations of corporate culture, management system, staff quality and so on, it is difficult to achieve success in the actual operation process. In recent years, with the increase of foreign-funded enterprises, some excellent enterprises in China are exploring their own lean production model through exchange and study. Combined with the actual production situation of screw compressor in W Company, this paper analyzes every link in the production process by using value flow diagram through value flow analysis method, and finds out the reasons for waste in every production link of enterprise. This paper studies how to use lean production theory to guide enterprises to optimize the existing screw compressor production line. This paper analyzes the problems existing in the production line of screw compressor in W Company, and puts forward the optimization scheme to improve the production status of the group enterprise. This paper first introduces the background and significance of the topic, and briefly introduces the lean production theory and value flow analysis method. The production and assembly line of screw compressor in W Company is analyzed by using value chart analysis method, and the value flow diagram is drawn. Through the analysis of the current value flow diagram, we find that the manufacturing system needs to be improved. According to the sales forecast and latest development plan of screw compressor in 2017, and guided by lean production theory, this paper designs the latest value flow chart of screw compressor production for W Company. The optimization scheme of manufacturing system for screw compressor is studied, and the production and manufacturing system is designed and implemented. In the course of the research, based on the different needs of the customers, the production capacity and online inventory of screw rod compressor production system are analyzed and expounded in detail. By using the detailed data to calculate, every index of the rod compressor production after lean production is demonstrated in detail, and the advantages of lean production mode itself are pointed out. At present, more and more enterprises have realized the practical significance of lean production theory for the development of enterprises, try to use lean theory to optimize enterprise production, expect success. But for enterprises, we must realize that lean production is not achieved through the optimization of a production line, lean production is in fact a continuous improvement, the pursuit of perfect process. Only in the process of analysis-better-re-analysis-re-improvement, constantly eliminating waste, researching and groping the mode of production in line with the enterprise itself, can the enterprise develop and grow stronger and stronger in the process of continuous improvement. Lean theory is a kind of foreign theory, but with the increase of its application in various industries, it will be enriched and sublimated in China, which will play a great role in the development and growth of Chinese enterprises.
