Software reliability simulation analysis method based on virtual reality and complex network

A software reliability simulation analysis method based on virtual reality and a complex network, comprising:

• obtaining network data of an object software under test, wherein the network data comprises functions and calling relationships, task sets, and task association relationships;
• establishing a two-layer coupling network according to the functions and the calling relationships, the task sets and the task association relationships, wherein the two-layer coupling network comprises:
• a three-dimensional function network and a three-dimensional task network;
• placing the two-layer coupling network in a virtual reality environment;
• determining a task assignment probability P based on an operation section;
• determining a task execution process in a sampling manner;
• executing a task to determine the dynamic change of the network in the coupling network in the virtual environment;
• determining and sorting the importance of function nodes according to whether the function nodes are called and the number that the function nodes are called.
