【摘要】：隨著我國(guó)經(jīng)濟(jì)的轉(zhuǎn)型,以及國(guó)家在經(jīng)濟(jì)政策上對(duì)中小企業(yè)大力扶持,一方面中小企業(yè)在國(guó)民經(jīng)濟(jì)發(fā)展中占據(jù)越來(lái)越重要的地位,并得到了快速的發(fā)展,另一方面,中小企業(yè)在發(fā)展的過(guò)程中也要面對(duì)日益提高的人力成本、硬件成本、原料成本、管理成本的上升所帶來(lái)的競(jìng)爭(zhēng)力的下降，如何在日益成熟的市場(chǎng)經(jīng)濟(jì)及激烈的市場(chǎng)競(jìng)爭(zhēng)環(huán)境中提高生產(chǎn)效率、降低企業(yè)運(yùn)營(yíng)成本、準(zhǔn)時(shí)交貨成為許多中小企業(yè)亟待解決的難題。 本文在綜合分析了優(yōu)化生產(chǎn)運(yùn)作系統(tǒng)各組成要素的理論方法基礎(chǔ)上,以新鐵德奧道岔有限公司生產(chǎn)運(yùn)作系統(tǒng)為研究對(duì)象,運(yùn)用理論聯(lián)系實(shí)際，定性分析和定量分析相結(jié)合的方法，首先重點(diǎn)對(duì)其結(jié)構(gòu)化要素中的生產(chǎn)線平衡要素存在的問(wèn)題進(jìn)行了分析及優(yōu)化。通過(guò)對(duì)各個(gè)車間線平衡率，月產(chǎn)能以及生產(chǎn)力的量化分析，找出整個(gè)生產(chǎn)線平衡存在的問(wèn)題，進(jìn)而運(yùn)用精益生產(chǎn)理論中的平衡理論方法對(duì)各個(gè)車間及整個(gè)生產(chǎn)線平衡進(jìn)行了定量?jī)?yōu)化； 其次對(duì)生產(chǎn)線平衡起支持和保障作用的非結(jié)構(gòu)化要素中人員組織要素、設(shè)備管理要素、庫(kù)存控制要素、生產(chǎn)計(jì)劃要素存在的問(wèn)題進(jìn)行了定性分析，對(duì)存在的問(wèn)題進(jìn)行了定性優(yōu)化； 最后本文對(duì)生產(chǎn)運(yùn)作系統(tǒng)優(yōu)化預(yù)期效果進(jìn)行了定量和定性的分析對(duì)比，，同時(shí)對(duì)優(yōu)化實(shí)施的原則和注意事項(xiàng)進(jìn)行了闡述。本文為新鐵德奧道岔有限公司生產(chǎn)運(yùn)作系統(tǒng)優(yōu)化提供了具體實(shí)施方法，對(duì)相似企業(yè)進(jìn)行生產(chǎn)運(yùn)作系統(tǒng)優(yōu)化具有指導(dǎo)意義，對(duì)精益生產(chǎn)理論中的方法在企業(yè)的靈活運(yùn)用提供了一種思路。
[Abstract]:With the economic transformation of our country and the strong support of the state to the small and medium-sized enterprises in the economic policy, on the one hand, the small and medium-sized enterprises occupy a more and more important position in the development of the national economy, and have got the rapid development, on the other hand, In the process of development, small and medium-sized enterprises also have to face the decline of competitiveness brought by the rising cost of manpower, hardware, raw materials and management. How to improve the production efficiency, reduce the operating cost and deliver goods on time in the increasingly mature market economy and fierce market competition environment has become a difficult problem to be solved by many small and medium-sized enterprises. On the basis of synthetically analyzing the theory and method of optimizing the elements of production operation system, this paper takes the production and operation system of Xintie Deo switch Co., Ltd as the research object, and applies theory to practice. In the combination of qualitative analysis and quantitative analysis, the problems existing in the production line balance elements in the structured elements are analyzed and optimized. Through the quantitative analysis of each workshop line balance rate, monthly production capacity and productivity, we find out the problems existing in the balance of the whole production line. Then, the balance theory of lean production theory is used to optimize the balance of each workshop and the whole production line quantitatively. The problems of equipment management, inventory control and production planning are qualitatively analyzed, and the problems are qualitatively optimized. Finally, the paper makes quantitative and qualitative analysis and comparison on the expected effect of optimization of production operation system, and expounds the principles and matters needing attention in the implementation of optimization. This paper provides a concrete implementation method for the optimization of production and operation system of Xintie de'ao turnout Co., Ltd. It has guiding significance for similar enterprises to optimize the production and operation system. This paper provides a method for flexible application of lean production theory in enterprises.
