Research on a Model Preaggregation Method for Multi-resolution Modeling

Abstract

Multi-resolution modeling technique is an effective method capable of solving complex system simulation. Aggregation and depolymerization is the most widely used method among multi-resolution modeling methods. The conversion delay problem is one of the leading technical difficulties faced by the aggregation-depolymerization method. The temporal variability and complexity of the simulation entities and the irrational algorithm are the main reasons for the conversion delay problem. The idea of implementing preaggregation of models to improve the aggregation and depolymerization methods is proposed. Through the method of threat early-warning assessment, multiple factors are considered to achieve preaggregation when necessary and minimize the number of aggregations.
