The invention relates to an LNG multi-point transport ship transport-capacity prediction scheduling method. A LNG multi-point transport ship transport-capacity prediction scheduling system is arranged in a networked structure formed by a plurality of long-term product supply points and a plurality of receiving stations; the system includes DCSs arranged in all the receiving stations and GMS terminals arranged in all the receiving stations, and an LNG multi-point transport ship transport-capacity scheduling simulation system platform arranged in any receiving station; and a discrete simulation deduction program integrating a Monte Carlo algorithm and an operational research queuing theory is arranged in a simulation module of the simulation system platform. According to the invention, various information of all receiving stations are obtained automatically by all DCSs; and according to a transport ship arrival time window and transport ship transport-capacity distribution scheme that is obtained by simulated deduction by the simulation system platform, all the GMS terminals generate transport ship transport-capacity scheduling plans of all the receiving stations, so that the accuracy and the practical operation are high. The provided method can be widely applied to a multi-transport ship transport-capacity prediction scheduling process in various networked systems with multiple long-term product supply points and multiple receiving stations.
