【摘要】:制造系統(tǒng)的布局設(shè)計(jì)與評(píng)價(jià)作為制造業(yè)中最為關(guān)鍵的環(huán)節(jié),它綜合考慮物流、信息流、生產(chǎn)能力、生產(chǎn)效率、生產(chǎn)成本等,將企業(yè)的制造資源合理、高效地整合在一個(gè)有限的生產(chǎn)空間里。良好的系統(tǒng)布局,不僅可以提高物料的流通速度,更是大大縮短產(chǎn)品生命周期,提高生產(chǎn)效率,從而加快企業(yè)響應(yīng)市場(chǎng)需求,為企業(yè)占領(lǐng)市場(chǎng)取得先機(jī)。 然而,隨著現(xiàn)代制造業(yè)的不斷發(fā)展,,新的制造技術(shù),如網(wǎng)絡(luò)化、智能化、系統(tǒng)化、柔性化等不斷涌現(xiàn)出來(lái),這也對(duì)制造業(yè)系統(tǒng)布局的設(shè)計(jì)和評(píng)價(jià)發(fā)出了新的挑戰(zhàn)。建立一個(gè)包含布局設(shè)計(jì)、物流系統(tǒng)設(shè)計(jì)、方案評(píng)價(jià)于一體的綜合性車間規(guī)劃平臺(tái)是至關(guān)重要的。因此本文在對(duì)車間布局進(jìn)行設(shè)計(jì)的同時(shí)也提出了一種新的車間布局評(píng)價(jià)方法,具體研究?jī)?nèi)容如下: 首先,建立基于SLP的車間布局設(shè)計(jì)方案。深入了解案例企業(yè)新建車間的原始數(shù)據(jù),應(yīng)用系統(tǒng)布置設(shè)計(jì)方法(SLP),對(duì)產(chǎn)品的生產(chǎn)工藝進(jìn)行合理設(shè)計(jì),以多種不同型號(hào)的閥門(mén)產(chǎn)品為例,分析各作業(yè)單位間的物流關(guān)系,計(jì)算各個(gè)作業(yè)單位接近程度,繪制出作業(yè)單位位置相關(guān)圖,以此為依據(jù),確定幾個(gè)合理的布局方案。 其次,構(gòu)建車間布局評(píng)價(jià)指標(biāo)體系。介紹評(píng)價(jià)指標(biāo)體系的建立方法及過(guò)程,以現(xiàn)有的車間布局評(píng)價(jià)指標(biāo)為基礎(chǔ),融入先進(jìn)制造業(yè)的新思想、新觀念,將綠色性以及人性化的相關(guān)指標(biāo)加入到車間布局評(píng)價(jià)指標(biāo)體系中,構(gòu)建適用于該車間的布局評(píng)價(jià)指標(biāo)體系。 最后,構(gòu)建基于熵權(quán)FAHP法對(duì)車間布局評(píng)價(jià)。通過(guò)對(duì)熵權(quán)法和FAHP的基本概念的簡(jiǎn)單介紹,構(gòu)建基于熵權(quán)FAHP綜合評(píng)價(jià)模型,著重介紹熵權(quán)法確定權(quán)重以及三角模糊數(shù)構(gòu)建模糊評(píng)價(jià)矩陣的過(guò)程,最后,運(yùn)用熵權(quán)FAHP模型對(duì)車間布局進(jìn)行有效評(píng)價(jià),并得出評(píng)價(jià)結(jié)果,為決策者提供依據(jù)。
[Abstract]:The layout design and evaluation of manufacturing system, as the most important link in manufacturing industry, consider the logistics, information flow, production capacity, production efficiency, production cost and so on, so that the manufacturing resources of the enterprise are reasonable. Efficiently integrate in a limited production space. A good system layout can not only increase the velocity of material circulation, but also shorten the life cycle of product greatly, improve production efficiency, so as to speed up the enterprise to respond to the market demand and obtain the first opportunity for the enterprise to occupy the market. However, with the continuous development of modern manufacturing industry, new manufacturing technologies, such as network, intelligence, systematization, flexibility and so on, are emerging, which also gives a new challenge to the design and evaluation of manufacturing system layout. It is very important to establish a comprehensive workshop planning platform which includes layout design, logistics system design and project evaluation. Therefore, a new method of workshop layout evaluation is proposed in this paper. The main contents are as follows: firstly, the design scheme of workshop layout based on SLP is established. Deeply understand the original data of the new workshop of the case enterprise, apply the system layout design method (SLP), carry on the reasonable design to the production process of the product, take many different types of valve products as an example, analyze the logistics relation among the various operating units, Based on the calculation of the close degree of each unit and the drawing of the relative map of the position of the operation unit, several reasonable layout schemes are determined. Secondly, the evaluation index system of workshop layout is constructed. The establishment method and process of evaluation index system are introduced. Based on the existing evaluation index of workshop layout, the new ideas and concepts of advanced manufacturing industry are introduced. The green and humanized indexes are added to the evaluation index system of workshop layout, and a layout evaluation index system suitable for the workshop is constructed. Finally, the evaluation of workshop layout based on entropy weight FAHP method is constructed. Through a brief introduction of the basic concepts of entropy weight method and FAHP, a comprehensive evaluation model based on entropy weight FAHP is constructed. The process of determining weight by entropy weight method and constructing fuzzy evaluation matrix by triangular fuzzy number are emphatically introduced. The entropy weight FAHP model is used to evaluate the workshop layout effectively, and the evaluation results are obtained, which provide the basis for the decision makers.
