【摘要】：伴隨著企業(yè)的發(fā)展以及變幻莫測(cè)的市場(chǎng)需求，大多數(shù)企業(yè)越來(lái)越重視怎樣在流水生產(chǎn)線的模式下提高生產(chǎn)線的整體效率以及追求生產(chǎn)線的同步化生產(chǎn)，企業(yè)在生產(chǎn)中評(píng)價(jià)一條流水生產(chǎn)線平衡性的優(yōu)劣時(shí)常常選擇平衡率這一量化指標(biāo)。 論文通過(guò)對(duì)裝配生產(chǎn)線平衡的研究，對(duì)中板鐳射流水生產(chǎn)線的問(wèn)題進(jìn)行了分析和解決。在本論文中，首先概述了生產(chǎn)線平衡的評(píng)價(jià)方式及基本概念并定義了改善生產(chǎn)線平衡的方式。本文通過(guò)對(duì)中板鐳射制程的現(xiàn)狀分析找出了焊接、裝夾、拆夾工作站等存在的問(wèn)題。然后，運(yùn)用五五法，TRIZ沖突問(wèn)題解決矛盾矩陣的分析方法，頭腦風(fēng)暴法，層次分析法，，人機(jī)聯(lián)合分析法對(duì)問(wèn)題進(jìn)行分析與改善。一次改善后使產(chǎn)能滿足了客戶需求，但是人力成本增加了，所以需要對(duì)一次改善后的制程進(jìn)行二次改善。接著，運(yùn)用WBS對(duì)鐳射制程進(jìn)行了作業(yè)拆分，運(yùn)用價(jià)值系數(shù)法對(duì)裝拆夾各工作單元進(jìn)行評(píng)估，運(yùn)用ECRS法對(duì)4個(gè)工作單元進(jìn)行了分析，并且針對(duì)ECRS的分析，設(shè)計(jì)出了一種氣缸式治具。最后對(duì)layout進(jìn)行了重置，并且通過(guò)線平衡進(jìn)行驗(yàn)證，結(jié)果表明改善方案達(dá)到了目標(biāo)。 本文通過(guò)對(duì)中板鐳射生產(chǎn)線平衡的改善，人力成本降低了33.3%，人均每小時(shí)產(chǎn)能UPPH提高了160.9%，生產(chǎn)線的平衡率提高了12.1%，預(yù)計(jì)年節(jié)約總成本為1427萬(wàn)人民幣。
[Abstract]:With the development of enterprises and the unpredictable market demand, most enterprises pay more and more attention to how to improve the overall efficiency of production line and pursue the synchronous production line under the mode of production line. When enterprises evaluate the balance of a production line, they often choose the quantitative index of balance rate. Through the research on the balance of assembly line, the problem of medium plate laser production line is analyzed and solved. In this paper, the evaluation method and basic concept of production line balance are summarized, and the ways to improve production line balance are defined. By analyzing the status quo of medium plate laser process, the problems of welding, clamping and disassembling workstation are found out in this paper. Then, the problem is analyzed and improved by the analysis method of solving the conflict matrix of Triz, the brainstorming method, the analytic hierarchy process and the man-machine joint analysis method. Once improved to meet customer demand for capacity, but increased labor costs, so the need for a second improvement in the process after the first improvement. Then, WBS is used to split the laser process, the value coefficient method is used to evaluate the work units, the ECRS method is used to analyze the four working units, and the ECRS method is used to analyze the ECRS. A cylinder type fixture is designed. Finally, the layout is reset and verified by line balance. The results show that the improved scheme achieves the goal. Through the improvement of the balance of medium plate laser production line, the labor cost has been reduced by 33. 3 percent, the per capita production capacity of UPPH has been increased by 160.9, the balance rate of the production line has increased by 12. 1, and the total cost saved per year is estimated to be 14.27 million RMB.
