Problems solved by technology

[0009] (1) In the existing supply chain logistics network simulation analysis method, it is difficult to establish a comprehensive model for comprehensive analysis of system behaviors at different levels; and due to the speed limit of the simulation test, even if a comprehensive simulation model is established, it will fail due to the long running time of the model. lack of practical value

[0010] (2) The current supply chain logistics network simulation analysis method uses different tools for analysis at different levels of the system, but the analysis process lacks comprehensive correlation considerations for different levels of models, and in the actual supply chain network model, the node and node The logistics behavior among them is strongly correlated, independent analysis methods cannot accurately describe and evaluate the system behavior

[0011] (3) The current supply chain logistics network simulation analysis is aimed at different system levels, and their behavior cycles are quite different, which makes it difficult to use distributed simulation methods for comprehensive operation analysis of models at different levels

[0013] There is a contradiction between accuracy and efficiency in the analysis of existing methods and tools for the supply chain logistics network: if there are too many details in the simulation, the analysis efficiency will be too low, and it can only be analyzed for a small-scale system of a single node; if the simulation granularity is relatively coarse , the speed is increased, and the whole network can be analyzed, but a lot of details are lost, and the system accuracy decreases
