Abstract: This paper uses the method of SLP to systematically analyze one enterprise's existing facility layout situation and presents an optimization scheme to reach the goal of reducing logistics cost.
Key words: SLP; Value Engineering; Optimization layout; Logistics
1 Introduction
Because of the fierce compel situation enterprises are facing, how to reduce cost effectively, quicken technology improvement, strengthen the ability of competition.
2 The Method of SLP and Production Logistics Optimization
Facility layout, on the basis of the functions the system should fulfill is to systematically design all facilities, personnel and investment in the system. Its key content 15 the design of the factory, shops, and facilities and so on. Its goal is to make the logistics route rational, that is, to enhance the whole production system's profit by changing or modulating the production logistics.
2.1 The logistics analysis of the metalworking shop
Metalworking shop is the processing center of this enterprise. Processing techniques are various with the different types of parts. There are 34 types of parts need to be processed perennial. The first step of design is the detailed analysis of processing techniques of the parts. Take the back moulding board for example (showed in Table l).
2.2 Draw location interrelated figure of all work units
In metalworking shop, the transfer of the size of the logistics amount is the most important thing to consider, that is, effects of other things can be ignored,So we make propinquity table (Table 6) only according to the work units' logistics interrelated table(Table 5), without taking the non-logistics Interrelated table into account.
3 Conclusions
So for the manufacturing, during the complex pressing process, the first step to reduce the product cost is to optimize facilities layout pattern inside the enterprise. SLP is undoubted an effective method to solve this problem.

摘要:本文運(yùn)用系統(tǒng)布置分析方法系統(tǒng)地分析一個(gè)制造企業(yè)生產(chǎn)設(shè)施布置現(xiàn)狀并且提出一個(gè)最佳化方案來達(dá)到削減物流成本的目標(biāo)。并且這個(gè)最佳化方案是非??尚械?。
關(guān)鍵詞:系統(tǒng)布置設(shè)計(jì);價(jià)值工程;優(yōu)化布置;物流
1 引言
面對現(xiàn)在的制造業(yè)激烈競爭現(xiàn)狀,怎樣去有效地削減成本,加快技術(shù)改進(jìn),增強(qiáng)競爭能力,縮短生產(chǎn)周期,改進(jìn)生產(chǎn)和服務(wù)質(zhì)量成為當(dāng)前制造業(yè)須處理的問題。
2 系統(tǒng)布置設(shè)計(jì)方法和生產(chǎn)物流優(yōu)化
設(shè)施布置,系統(tǒng)的基本功能必須實(shí)現(xiàn),也要對系統(tǒng)中的設(shè)備、人員、投資等進(jìn)行系統(tǒng)的設(shè)計(jì)。它的核心內(nèi)容是對工廠、車間、設(shè)備布局等等資源的設(shè)計(jì)。它的目標(biāo)就是使物流路線合理化,因此,通過改變或調(diào)制生產(chǎn)物流來提高整個(gè)生產(chǎn)系統(tǒng)的利潤。
2.1 金工車間的物流分析
加工工藝分析。加工車間是制造企業(yè)的處理中心。不同類型部分加工工藝是很多的。有34個(gè)部分需要長期處理。設(shè)計(jì)的第一步就是對零件的加工工藝進(jìn)行詳細(xì)分析。取后模板加工工藝為(表1)。
2.2 繪制作業(yè)單位位置相關(guān)圖
在金工車間,物流轉(zhuǎn)移量被認(rèn)為是最重要的事情,不需要考慮其他方面的影響,所以我們不考慮非物流相關(guān)表(表6)僅僅記錄作業(yè)單位綜合相互關(guān)系圖(表5),沒有對非物流強(qiáng)度進(jìn)行記錄。
3 結(jié)論
所以對于加工制造,在復(fù)雜的生產(chǎn)過程中,降低生產(chǎn)成本的第一步是得到在制造車間的設(shè)施布局最優(yōu)化方案。解決這個(gè)問題,系統(tǒng)設(shè)施設(shè)計(jì)無可厚非是一個(gè)有效的方法。
