Production Bottleneck Shiftiness Study

Phenomenon of bottleneck shiftiness was studied in this paper, including bottleneck shiftiness causes, its representation and solutions. In this study, bottleneck shiftiness causes were mainly divided in two kinds based on its inner qualities, one kind was demand fluctuation and the other kind was facility exception. In order to keep relative stability of the production system and reduce complexity of the production management, corresponding solutions were presented based on principles of the Theory of Constraints, respectively according to causes classified above, material release control and buffer management were two efficient methods in dealing with bottleneck shiftiness, examples of these two methods were given to help enterprises know well how to prevent the appearance of unexpected bottlenecks and to reduce the unexpected production fluctuate when the bottleneck shiftiness is unavoidable.
