【摘要】：發(fā)動(dòng)機(jī)是汽車的關(guān)鍵零部件,制造工藝相當(dāng)復(fù)雜,其高效的生產(chǎn)離不開一條規(guī)劃水平先進(jìn)的生產(chǎn)線,其中生產(chǎn)線布局的好壞將會(huì)直接影響到最終的實(shí)際運(yùn)行效果。工廠平面設(shè)施布局就是指在給定的使用空間內(nèi),對(duì)特定的生產(chǎn)單元以及工作區(qū)域進(jìn)行組合布局,將各類資源進(jìn)行最佳的優(yōu)化,使其能為企業(yè)運(yùn)作有效服務(wù)。一般情況下,在規(guī)劃一個(gè)全新發(fā)動(dòng)機(jī)工廠時(shí),將會(huì)受到以下一些因素的限制,廠區(qū)使用面積的限制、將來(lái)可擴(kuò)展方向的限制以及廠內(nèi)物流運(yùn)輸路線的限制等。同時(shí),考慮到生產(chǎn)線布局的再次調(diào)整難度高,不同的設(shè)備布局方式會(huì)造成車間場(chǎng)地利用率、設(shè)備可維修性的差異等,將會(huì)直接對(duì)今后的使用造成困難。因此,必須對(duì)生產(chǎn)線的布局進(jìn)行系統(tǒng)性的規(guī)劃,并對(duì)考慮了不同影響因素的方案進(jìn)行評(píng)審、比較,最終選擇布局合理性更高,對(duì)實(shí)際生產(chǎn)影響最小的方案,以幫助企業(yè)獲得最佳的經(jīng)濟(jì)效益。在以往的制造系統(tǒng)規(guī)劃中,特別是中小型企業(yè)的項(xiàng)目規(guī)劃系統(tǒng)中,工程師大多注重制造工藝的實(shí)現(xiàn),使設(shè)備能夠加工出合格的產(chǎn)品,但對(duì)于生產(chǎn)線的精益規(guī)劃理念以及制造系統(tǒng)整體運(yùn)作的效能評(píng)估能力考慮相對(duì)不足。因此,在生產(chǎn)線布局規(guī)劃完畢,尚未投入大量資金建造廠房、購(gòu)買生產(chǎn)設(shè)備之前,如何能根據(jù)已有的規(guī)劃信息并結(jié)合以往生產(chǎn)經(jīng)驗(yàn)數(shù)據(jù)來(lái)預(yù)判這條虛擬生產(chǎn)線的生產(chǎn)效率,將幫助企業(yè)管理層進(jìn)行系統(tǒng)的生產(chǎn)線規(guī)劃能力評(píng)估,并對(duì)組成生產(chǎn)線的設(shè)備開動(dòng)率以及人員負(fù)荷、排班頻次等關(guān)鍵生產(chǎn)運(yùn)作元素有更好的認(rèn)識(shí)。針對(duì)前文所述,并結(jié)合本人在公司內(nèi)實(shí)際的工作內(nèi)容,本論文開展了以下幾個(gè)方面的研究。1.對(duì)發(fā)動(dòng)機(jī)生產(chǎn)線進(jìn)行布局規(guī)劃。一般新工廠的規(guī)劃都存在一系列限定因素,如土地使用面積的限制、擴(kuò)建能力的限制以及車間外部廠區(qū)規(guī)劃限制等,本論文將利用系統(tǒng)化布局規(guī)劃(Systematic Layout Planning,SLP)方法,對(duì)發(fā)動(dòng)機(jī)生產(chǎn)線的各主要生產(chǎn)單元進(jìn)行系統(tǒng)的布局與規(guī)劃,同時(shí)針對(duì)不同的設(shè)備布局方案,對(duì)組成發(fā)動(dòng)機(jī)關(guān)鍵生產(chǎn)專線進(jìn)行詳細(xì)分析和評(píng)估,最終通過(guò)方案對(duì)比,選擇相對(duì)合理的方案,以達(dá)到提高生產(chǎn)線規(guī)劃資源利用率的目的。2.構(gòu)建生產(chǎn)線仿真模型。使用witness仿真軟件初步建立該發(fā)動(dòng)機(jī)生產(chǎn)線的模型框架,包括一系列的變量、仿真關(guān)鍵元素的定義及內(nèi)部公式設(shè)定。對(duì)發(fā)動(dòng)機(jī)機(jī)加工線內(nèi)的典型設(shè)備及零件輸送方式等進(jìn)行仿真模型的構(gòu)建。3.對(duì)生產(chǎn)線能力進(jìn)行仿真。收集發(fā)動(dòng)機(jī)生產(chǎn)線的基本生產(chǎn)數(shù)據(jù),包括設(shè)備加工節(jié)拍,設(shè)備故障數(shù)據(jù),設(shè)備換刀時(shí)間,手動(dòng)操作時(shí)間、生產(chǎn)換型時(shí)間和排班數(shù)據(jù)等等,首先通過(guò)對(duì)設(shè)備加工節(jié)拍的分析,了解設(shè)備單機(jī)開動(dòng)率的大致情況并找出生產(chǎn)線的初步瓶頸工位,然后根據(jù)項(xiàng)目生產(chǎn)綱領(lǐng)設(shè)定仿真目標(biāo),驗(yàn)證考慮到設(shè)備加工節(jié)拍、停機(jī)和換刀等一系列生產(chǎn)制約因素后的生產(chǎn)線輸出能力。最后根據(jù)不同的換型排班策略,來(lái)模擬該生產(chǎn)線每周換型運(yùn)作情況,分析不同換型頻次對(duì)該生產(chǎn)線的產(chǎn)量輸出影響,并對(duì)不滿足換型頻次的情況加以分析并給出實(shí)際解決方案。
[Abstract]:The engine is the key spare parts manufacturing process is very complex, its efficient production cannot do without a planning level of advanced production line, the production line layout will directly affect the actual operation of the final result. The factory facilities layout plane is refers to the use of a given space, the combination of the layout of the specific production unit as well as working area, all kinds of resources for the best optimization, so that it can work effectively to serve the enterprise. Generally, in the planning of a new engine factory, will be some of the following factors, the use of factory area restrictions, the future direction of propagation of constraints and internal logistics transportation route restrictions. At the same time, considering the production line layout adjustment again is high, the layout of the equipment in different ways will cause the workshop space utilization rate, the maintainability of the difference will be. The direct cause difficulties for future use. Therefore, must be on the production line layout of the system of planning, and to consider the scheme of different influential factors for evaluation, comparison, the final choice layout more rational, the scheme of the minimum impact on the actual production, to help enterprises to obtain the best economic benefits in manufacturing planning. The system in the past, especially the project planning system for small and medium sized enterprises, implementation engineers pay more attention to the manufacturing process, so that the equipment can produce the qualified product, but the lean concept for the production line planning and manufacturing efficiency of the system overall operation capacity assessment considering the relative lack. Therefore, in the completion of production line layout yet, invest a lot of money building, before the purchase of production equipment, how can the information according to the planning and production data with previous experience to predict the virtual production line The production efficiency, will help the enterprise management ability evaluation planning production line system, and the utilization rate and load on the composition of production line equipment, scheduling frequency key operation elements have a better understanding. According to the above, and combined with my actual work in the company, this paper carried out research.1. the following aspects of the layout planning of engine production line. The general program of new plant has a limited set of factors, such as land use restrictions, the expansion of capacity constraints and external restrictions on workshop factory planning, this paper will use the systematic layout planning (Systematic Layout, Planning, SLP) method of engine the production line the main production unit layout and planning system, and according to the different layout scheme, the key components of production line engine in detail And the final assessment, through the scheme contrast, choose a relatively reasonable scheme, in order to improve the production line planning resource utilization rate of the construction of.2. production line simulation model. The model framework of witness simulation software is used to establish the engine production line, including a series of variables, the definition and formula of the key elements of internal simulation settings. Construction of.3. the simulation of production line equipment and parts of the typical machining line inside the engine transmission mode of the simulation model. The basic production data collection engine production line equipment, including equipment failure data, processing time, tool changing time of equipment, manual operation time, changeover time and the scheduling of production data and so on, first through the analysis the equipment processing time, to understand the general situation of equipment operation rate and find out the bottleneck station preliminary production line, and then according to the project production program. 瀹氫豢鐪熺洰鏍，
