Based on the discrete event dynamic system theory and computer simulation technology，we establish a logical model to realize the logistics functions of the coal transshipment system，the jetty handling system，and shuttle transportation，etc. By studying the capacity matching optimization，construction investment，and operation cost of the whole coal handling system，we obtain the analysis methods of construction investment and operation cost of different system combinations to determine the optimal configuration of loading and unloading system，which serves as a reference for the selection of the number of shuttles in similar transshipment system and a reasonable selection of jetty handling capacity.
