Method for determining change impact of software module based on dynamic simulation of complex networks

Abstract

The invention discloses a method for determining the change impact of software module based on dynamic simulation of complex networks, which belongs to the field of software complex networks. The method comprises the following steps of: first statically scanning the source code of the target software, and constructing a network of software attribute methods; then identifying the granularity of thesoftware module according to the actual needs, constructing a software complex network model, and dynamically simulating the influence propagation of the change after the determination of the software module to obtain the quantized value of the degree of influence of each node and the scope of the change impact; finally, summing the node with the attenuation coefficient of each change propagationgeneration as the quantized value of the degree of influence of the node, and depending on this quantized value to acquire a visualization result graph of change impact level of the software network.According to the method for determining a change impact of software module based on dynamic simulation of complex networks, considering the change propagation characteristics and the node characteristics are comprehensively considered for dynamic simulation, the entire measurement analysis process can be implemented in the background, and is established in a fully automated process to ensure theminimum human and time costs are reduced, by utilized the attenuation process of the change impact.

Description

technical field [0001] The invention belongs to the field of complex software networks, and relates to a method for determining the impact of software module changes based on software network dynamic simulation. Background technique [0002] With the continuous development of information technology, computer software has been widely used in all aspects of human life, and has made great contributions to the development of human society and economy and the progress of scientific research. The importance of software has risen sharply. At the same time, due to the increasing demand for software functions and the increasingly complex software application environment, the scale and complexity of software systems continue to grow. Changes can be due to new requirements put forward by users, errors found in the process of using the software, or changes in the environment in which the software is used. When a change is made to the software, it will definitely have some potential imp...
