The invention discloses a sequential model scheduling method of a distributed simulation system, and belongs to the technical field of complex system simulation. The distributed simulation system comprises a client side, a master control engine and computational nodes. The sequential model scheduling method of the distributed simulation system comprises the steps that 1, simulation run is initialized, and model distribution is completed; 2, run simulation is carried out, that is, the client side sends a scheduling instruction to the master control engine, the master control engine receives the scheduling instruction, a first-stage run model is obtained, a drive instruction is sent to the node where the first-stage run model is located, and models on the computational nodes are driven to run; 3, the computational nodes receive the drive instruction to drive the models to run, and result data is generated and output to the master control engine; 4, the master control engine receives the result data and resolves the result data, and downstream model sets are obtained; 6, a downstream model ID set is subjected to traversal; 6, whether the current model is removed or not is judged; 7, whether the number of the downstream model sets is reached or not is judged; 8, the downstream set models are vacant or not is judged, the step 3 is executed, and the method is completed. According to the method, model run efficiency is improved, master control engine loads are reduced, time consumed for model scheduling is shortened, and high universality is achieved.
