Consequently, this research finds there are three major factors to influence the productivity of UPA-ST’s assemble line: the first is the bottleneck station, the second is the station which exists big variance of working time, the third is the unbalance operation of the assemble line. For each major factors, this research uses data collection and analysis to understand how these three major factors affect the productivity of assemble line. Finally, it increases the productivity via taking apart the operation and synchronous way; it makes assemble line balance via adjust the order of work station and combination; it reduces the variance of the working station which exists big variance via understanding the source of variance and building the autonomous quality-control process. Through reducing the productivity influence of these three major factors, it consequently make the assemble line increase the output and reduce the input of manpower to increase the productivity. 國立政治大學 http://thesis.lib.nccu.edu.tw/cgi-bin/cdrfb3/gsweb.cgi?o=dstdcdr&i=sid=%22G0913550052%22. text 中文 Copyright © nccu library on behalf of the copyright holders |
