摘要
生產(chǎn)線平衡是一門很大的學(xué)問(wèn)，生產(chǎn)線平衡直接關(guān)系到生產(chǎn)線的正常使用。生產(chǎn)線平衡即是對(duì)某條生產(chǎn)線的全部工序進(jìn)行平均化，調(diào)整作業(yè)負(fù)荷，以使各作業(yè)時(shí)間盡可能相近的技術(shù)手段與方法。目的是消除作業(yè)間的不平衡率損失和生產(chǎn)過(guò)剩。在生產(chǎn)線的生產(chǎn)模式下，如何切實(shí)提高生產(chǎn)線整體效率和產(chǎn)能，降低生產(chǎn)節(jié)拍，精簡(jiǎn)工作人員和機(jī)器設(shè)備，減少工序之間的在制品，以及追求同步化的生產(chǎn)模式越來(lái)越受到眾多制造型企業(yè)的重視。生產(chǎn)線平衡率在某種程度上標(biāo)志著企業(yè)設(shè)備和人員的利用率，并代表著生產(chǎn)線的生產(chǎn)能力?；跈C(jī)械加工生產(chǎn)企業(yè)生產(chǎn)線的工藝平衡問(wèn)題是一般勞動(dòng)密集型生產(chǎn)企業(yè)的普遍存在問(wèn)題，分析工藝平衡是提高生產(chǎn)率的關(guān)鍵問(wèn)題,有助于采取相應(yīng)的措施，以利于企業(yè)生產(chǎn)效率的提高。
本研究是針對(duì)xx有限公司生產(chǎn)的實(shí)際要求，運(yùn)用工業(yè)工程及基本理論與方法，對(duì)xx公司不銹鋼制品拋光B09生產(chǎn)流水線進(jìn)行改善，以提高其產(chǎn)線平衡率目的。首先，敘述了論文的研究背景在國(guó)內(nèi)外發(fā)展的現(xiàn)狀 ，以及研究?jī)?nèi)容和研究思路；其次對(duì)裝配線概念及工業(yè)工程理論進(jìn)行了闡述，提出了裝配線平衡的改善方向；其次針對(duì)xx公司的生產(chǎn)線平衡方面的問(wèn)題進(jìn)行現(xiàn)場(chǎng)調(diào)查分析，通過(guò)流程程序分析等方法確定公司產(chǎn)品的生產(chǎn)流程以及生產(chǎn)線上工位的分布情況；然后采用作業(yè)測(cè)定的方法科學(xué)計(jì)算出每道工序的標(biāo)準(zhǔn)時(shí)間，再通過(guò)生產(chǎn)線的評(píng)價(jià)指標(biāo)來(lái)反映生產(chǎn)線實(shí)際運(yùn)行效率；最后針對(duì)性地提出具體、合理的改善方法，并對(duì)比改善前后裝配線的平衡率，以此來(lái)說(shuō)明通過(guò)改善在一定程度上提高了該公司生產(chǎn)線平衡率；總結(jié)改善的效果及原因，并針對(duì)改善后的效果評(píng)價(jià)提出后期改善的重點(diǎn)。

Abstract
Line balancing is a lot of learning, line balancing is directly related to the normal use of the production line. Production line that is on the balance of all the processes of a production line averaging, adjust workloads, so that each time the job as closely as possible technical means and methods. The purpose is to eliminate losses and overproduction unbalance between jobs. The utilization rate of the production line balancing somehow marks the business equipment and personnel, and represents the production capacity of the production line. Balance machining production process production line is a common problem based on the general labor-intensive manufacturing enterprises, the analysis process is to improve the productivity of balancing key issues and help take the appropriate measures to facilitate production efficiency.
This study is required for the actual production of the San Yuan Co., the use of industrial engineering and basic theory and method of San Yuan polished stainless steel production lines B09 improvements to increase its rate of production line balancing purposes. First of all, the paper describes the industrial engineering theory of production line balancing improve involves the related theory and production line of the eva luation index, and expounds the influence factors of production line balancing, and puts forward the improvement of production line balancing direction;Next to the production line balancing Sheng yuan wood industry company of the field investigation and analysis, this paper through the process analysis, procedure analysis method to determine the company the production technique, production process and production line location distribution; Then the work measurement method of scientific calculated each procedure of standard time, again through the eva luation indexes of production line to reflect the actual operation efficiency production line; Finally pointed proposed specific, reasonable way of improvement, and improve the balance of production line after contrast ratio, so as to show that, through improving promotes, to some degree, the company production line balancing rate; Summarize the effect of improving and the reason, and to improve the effect after the eva luation of the late put forward improving key.

Key words: Production Line Balance; Balance Rate; Flow Process Chart; Work；Improve
