A dispatching method and system based on multiple levels of steady state production rate in working benches are provided. The dispatching method includes the following steps: receiving a plurality of real-time streaming data regarding a plurality of products being produced by a plurality of productive working benches; grouping the production rate values comprised in each real-time streaming data according to a first data binning technique, so as to produce a first steady state production rate value corresponding to each real-time streaming data; grouping the production rate values comprised in each real-time streaming data according to a second data binning technique, so as to produce a second steady state production rate value corresponding to each real-time streaming data; and determining a dispatching message of a to-be-produced product according to a portion of the first steady state production rate values and a portion of the second steady state production rate values.
