The invention relates to a dynamic spot goods forecasting and scheduling method for a liquefied natural gas (LNG) receiving station. The method comprises the following steps: setting an LNG dynamic spot goods forecasting and scheduling system consisting of a distributed control system (DCS), an LNG dynamic spot goods forecasting and scheduling simulation system platform and a GMS terminal in the LNG receiving station, wherein the simulation system platform comprises an initial parameter database, a simulation module with a built-in discrete simulation deduction program for integrating a Monte Carlo algorithm and a queuing theory of operational research, an index and report display module and an analytic database, and the simulation system platform is connected with the DCS and the GMS terminal via a network; executing simulation deduction in a long-term ADP mode by virtue of the simulation module, executing simulation deduction in a long-term ADP and dynamic spot goods request interaction mode, and generating an LNG dynamic spot goods scheduling plan according to the simulation deduction result by virtue of the GMS terminal. According to the method, the dynamic spot goods scheduling plan and the original long-term ADP are integrated to form reliable and complete ADP information, and the method can be widely applied to a dynamic spot goods forecasting and scheduling process for various LNG receiving stations.
