One of the most important issues in an assembly line balancing problem is to control a flow of production and manufacturing to provide continuous flow to balance the production line. For this purpose, a line balancing problem was considered for a special assembly line in an automotive factory. A new algorithm was required to deal with balancing an assembly line which consisted of the same job which must be performed by more than one worker at the same time. In this way, the new algorithm was expected to be effective in such a case that jobs were simultaneously completed in a parallel way. In order to measure effectiveness of the proposed algorithm, performance criteria were identified as total number of assembly station, total number of workers, and line productivity. As a result of the application of the proposed algorithm with taking into consideration factors such as cycle time, an allowable number of workers in an assembly station, and an allowable idle time of a worker, alternative solutions were determined in order to measure these criteria. However, these alternative solutions do not give any information about which of the solutions provide not only minimization of the number of assembly station and number of workers on the line but also maximize the line productivity at the same time. Hereby, a multi-response Taguchi method was applied in order to investigate levels of factors which directly affected system performance criteria. 相似文献

Automated production lines of a parallel–serial structure are most productive in the manufacturing area. Designers of automated lines segment into sections with several stations place buffers between the series of sections that enable increasing the productivity rate. The failure of one station leads to stoppage of only one section of the automated line, while other sections continue to work and machine parts are stored or consumed from buffers. In real production condition, the capacity of a buffer is limited, and a buffer can compensate only in part stoppages of sections in an automated line. This article represents a new analytical approach for calculating the productivity rate of the section-based automated line of a parallel–serial action with embedded buffers of limited capacity. It enables to solve the problem of structural optimization of the line by the criterion of a maximal productivity rate, which yields the optimal number of serial and parallel stations, and the number of sections. 相似文献
