Problems solved by technology

[0006] To sum up, the problems existing in the existing technology are: the resource and time costs required for software evolution in a changeable environment are high; the behavior state of the existing software system before and after evolution does not satisfy the consistency, resulting in the evolution of the system Deviating from the established functional goals, causing unknowable problems;
[0008] The method of finding the inconsistency of the theoretical model through methods such as the cloud domain and other documents, and then modifying it to finally maintain the evolutionary consistency requires relatively high requirements on related technologies and hardware, and is not easy to operate

Abstract

The invention belongs to the field of software evolution technology and discloses an analysis method and system for system functional behavior consistency in software evolution. According to the method, Petri-net is adopted to perform formalized modeling on a to-be-evolved software system; a corresponding system Petri-net model is converted into a state transition diagram (Petri-net reachability graph), wherein each state in the state transition diagram is a corresponding system behavior state; and then system evolution consistency analysis is performed based on the state transition diagram. Through the method, whether consistency is guaranteed before and after evolution is analyzed starting from a system behavior layer rather than a component behavior layer. Compared with direct analysisof the system Petri-net model, the method is simpler and easy to understand; and the system can perform software dynamic configuration and update with as small cost as possible at an operating moment.

Description

technical field [0001] The invention belongs to the technical field of software evolution, and in particular relates to a method and system for analyzing the consistency of system function behavior in software evolution. Background technique [0002] Constructivity and evolution are two basic characteristics of software. In the era of rapid development of this science and technology now, the computer software of the present invention is also undergoing major changes, changing with each passing day. Along with the constant change of factors such as user's demand, operation environment, software system needs to make corresponding change in operation to adapt to new demand and environment, and this just means that the software of the present invention needs to constantly evolve to reach new requirement and then can continue to be used. Software evolution is divided into static evolution and dynamic evolution: static evolution means that the entire software system stops runnin...
