Through the understanding of the enterprises and production lines the basic situation and stopwatch time study method of the production line each station conduct a site measurement when; to find the bottleneck process; motilin analysis on the bottleneck work, using 5W1H questions technology, ECRS principle,and the principle of motion economy, the initial improvement; detail division of the bottleneck station and other station to improve operational processes, and the bottleneck station and other stations to improve operational processes, and the formation of new operational processes will improve the program to operate experiments. Improve before and after the bottleneck station is reduced from 52.34s to 26.17s, the daily output from 478 to 875, the assembly line each year to save the economy 216,130.40 yuan, reaching to improve the program the original intention.Keywords: Balance line balancing, Bottleneck, stopwatch time study 目录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc294799279 第一章 绪论 PAGEREF _Toc294799279 \h - 1 - HYPERLINK \l _Toc294799280 1
