Description

technical field [0001] The invention relates to the technical field of modeling and simulation, in particular to a method for realizing automatic initialization of a parallel discrete event simulation system suitable for complex system simulation. Background technique [0002] Since the 1990s when developed countries such as Europe and the United States began to study parallel discrete event simulation technology, several parallel discrete event simulation operation support environments based on high-performance computing platforms have been launched, such as SPEEDES, Warped, Parsec, usik, etc. These parallel discrete event simulation support environments are widely used in complex system simulation applications such as large-scale ecological environment simulation, computational system biology simulation, large-scale combat simulation in complex war environments, national and national defense strategy research, crisis prediction, early warning, and decision-making. , provid...

Problems solved by technology

Such methods require simulation developers to manually search for the corresponding initialization data from the scenario file on the basis of understanding the system initialization requirements and the data structure of the scenario file, and manually write codes to assign values ​​to the corresponding initialization variables, resulting in the realization of the simulation system initialization program. The workload is large, the probability of introducing manual errors is high, and the ability to adapt to changes in scenario files is also poor
