【摘要】：本文主要從精益生產(chǎn)的理論出發(fā)，結(jié)合中宇公司目前庫存現(xiàn)狀進(jìn)行研究，并達(dá)到改善庫存并保持庫存最優(yōu)數(shù)量的目的。精益生產(chǎn)模式基本的內(nèi)容就是及時(shí)制造、消滅故障、消除一切浪費(fèi)、零庫存努力。國外始創(chuàng)并且應(yīng)用效果顯著的是日本豐田汽車公司。國內(nèi)的汽車制造和流水作業(yè)制造業(yè)早已引進(jìn)并取得實(shí)效。就是在中央空調(diào)生產(chǎn)企業(yè)，目前也有許多企業(yè)都在嘗試這一先進(jìn)的管理模式，譬如美的、約克、麥克維爾等。但收效甚微，究其原因，主要是國內(nèi)的企業(yè)沒有結(jié)合到國內(nèi)、廠內(nèi)實(shí)際情況進(jìn)行變通與取舍，本次主要是結(jié)合到中宇的實(shí)際情況進(jìn)行改革，以達(dá)到降低庫存的目的。 本文提出在中宇實(shí)施新的庫存模式是借用精益生產(chǎn)等管理方式等模式的精髓，在中央空調(diào)生產(chǎn)運(yùn)營管理中針對大批量生產(chǎn)、大消耗、大周轉(zhuǎn)量、大庫存量和不能按時(shí)交貨等具體問題，提出適應(yīng)“即時(shí)生產(chǎn)”的相關(guān)改造方案，包括生產(chǎn)系統(tǒng)的計(jì)劃、組織、調(diào)度、協(xié)調(diào)以及與生產(chǎn)運(yùn)營管理密切相關(guān)的現(xiàn)場管理系統(tǒng)的相應(yīng)改造設(shè)計(jì)方案。改造方案提出了以訂單為龍頭，合理評審交期，以拉動式生產(chǎn)為工具，加以ABC分析法及“VMI”庫存管理方式為輔助，進(jìn)行流程再造設(shè)計(jì)，重新劃分職責(zé)，強(qiáng)調(diào)拉動式生產(chǎn)，提高工作效率。通過每道工序的精確控制，實(shí)現(xiàn)中間周轉(zhuǎn)在制品周轉(zhuǎn)量和產(chǎn)成品庫存量大幅度壓縮，減少幅度大于50％。改造方案提出了按訂單生產(chǎn)的“物料需求計(jì)劃”，公司要通過對生產(chǎn)均衡性、穩(wěn)定性的控制，，實(shí)現(xiàn)大幅度壓縮原材料庫存量的目的。 本次研究的目標(biāo)是：重點(diǎn)原材料庫存金額從500萬元壓減到200萬元，整體原材料庫存金額從900萬元壓減到400萬元左右。并對于實(shí)施新的庫存管理模式改造所需的投資進(jìn)行了預(yù)測和分析。對在中宇新的庫存管理模式改造可能存在的風(fēng)險(xiǎn)和化解風(fēng)險(xiǎn)的措施提出比較詳細(xì)的分析和討論。
[Abstract]:Based on the theory of lean production, this paper studies the current inventory situation of Zhongyu Company, and achieves the purpose of improving inventory and keeping the optimal quantity of inventory. Lean production mode is the basic content of timely manufacturing, eliminate failures, eliminate all waste, zero inventory efforts. The first and most effective application abroad is the Japanese Toyota Motor Company. Domestic automobile manufacturing and streamline manufacturing industry has been introduced and achieved practical results. Even in the central air conditioning production enterprises, at present, many enterprises are trying this advanced management model, such as Midea, York, McVille, etc. But the effect is very little, the main reason is that the domestic enterprises do not combine into the domestic, the actual situation in the factory to adapt and choose, this is mainly combined with the actual situation of Zhongyu to carry on the reform, in order to achieve the purpose of reducing inventory. This paper puts forward that the implementation of the new inventory model in Zhongyu is the quintessence of the management mode such as lean production and so on. In the production and operation management of central air conditioning, it aims at mass production, large consumption, large turnover, etc. The specific problems such as large inventory and failure to deliver goods on time are put forward to adapt to "immediate production", including planning, organization and scheduling of production system. Coordinate and modify the design of site management system closely related to production and operation management. According to the reform plan, taking order as the lead, reasonable evaluation and delivery time, taking pull production as the tool, taking ABC analysis method and VMI inventory management method as the assistant, the process reengineering design is carried out, the responsibility is reclassified, and the pull type production is emphasized. Improve working efficiency. Through the precise control of each working procedure, the turnover of intermediate WIP and the stock of finished goods are greatly compressed, and the extent of reduction is more than 50%. The reconstruction plan puts forward the "material requirement plan" which is produced according to the order. The company will achieve the purpose of reducing the stock of raw materials by controlling the balance and stability of production. The aim of this study is to reduce the inventory amount of key raw materials from 5 million yuan to 2 million yuan, and to reduce the total inventory amount of raw materials from 9 million yuan to 4 million yuan. The investment needed to implement the new inventory management model is forecasted and analyzed. This paper puts forward detailed analysis and discussion on the possible risks of the new inventory management model in Zhongyu and the measures to resolve the risks.
