Method of Simulation on Determining Bottleneck Resource

The relations among bottleneck resources, buffer and the leadtime and the methods on identifying the bottleneck resources are analyzed. A method based on QGERT(QueueGraphic Evaluation and Reniew Technology) and simulation technique was brought forward to aim for the situation in which every process's capacity was near to each other. The pragmatic situation of production can be actually embodied and the bottleneck resources of the system can be accurately identified by the method. So the enterprise should undertake a short leadtime and economize labor force and materials.
