面向大批量定制的MTM在装配线上的应用研究
|
摘要
针对装配线生产效率较低的问题,对产品的生产方式、作业人员动作、工时分析方法等方面进行了研究。在标准化作业过程中应用MTM法对制定标准工时与提高生产效率进行了归纳,提出了一种基于大批量定制的MTM在装配线上的应用的方法,利用"方法-时间-测量-通用系统"(MTM-UAS)方法对装配线进行了动作分析,根据客户订单要求进行了产品方案设计,选择通用零部件,用MTM-UAS方法对通用部件的组装动作进行了分析,将分析出的时间组合作为模块存储在模块库中,利用可重用模块计算了标准工时,制定了作业指导书。研究结果表明:该方法节约了工时分析时间,提高了动作时间分析的效率和产品生产效率,既满足了客户对产品的个性化需求,也提高了产品的响应速度。
Aiming at the problem that assembly line production efficiency is low,the mode of production,operation of operators,method of analyzing man-hours and so on were studied,the MTM method was applied to establish the standard labor time and improve production efficiency when the standardization work was made. A method of MTM application based on mass customization was proposed in assembly line,the method of using "method-time-measuring-general system"( MTM-UAS) was carried out on the movement analysis of assembly line. According to the needs of a customer's order,general parts were chose and assembling operation of universal parts was analyzed with the MTMUAS method,analysis of time combination as a module was stored in the module library,reusable module was used to calculate the standard working hours,make the work instructions. The results indicate that the method saves industrial engineers' timeanalysis,improve the efficiency of the movement time analysis and product production efficiency,not only satisfy the personalized needs of customers for products,but also improve the response speed of the products.
