Software system structure adaptability evaluation method considering multiple factors

Abstract

The invention provides a software system structure adaptability evaluation method considering multiple factors, and belongs to the technical field of software system structures. According to the method, the method comprises the following steps: obtaining adaptive strategies from design documents and requirement specification instructions, dividing the strategies into component structure change strategies, component parameter change strategies and connecting piece parameter change strategies according to operation types, and counting the change rates of the strategies; modeling changes of a software system structure driven by different strategies by using an extended UML component diagram, setting a difficulty level weight of strategy implementation based on a component diagram model, calculating a change influence degree, and finally comprehensively calculating the adaptability of the software system structure driven by an adaptive strategy to judge whether the software system structure is feasible or not. According to the method, positive factors and negative factors which influence the adaptability of the system structure are considered, the structure of the system structure and adjustment of parameters of the system structure are considered, and the adaptability of the system structure under the adaptation strategy can be obtained more comprehensively, truly and quantitatively for designers to use.

Description

technical field [0001] The invention relates to the technical field of software architecture, in particular to a software architecture adaptability evaluation method considering multiple factors. Background technique [0002] As an important product of the software design stage, the quality of software architecture design will directly determine the quality of future software, which has become an important research field of software engineering. Software architecture adaptability refers to the ability of the architecture to adjust the structure and parameters with a small cost and degree of influence driven by the adaptation strategy to meet the changes in the environment and user requirements. A lot of practice shows that the adaptability of the software architecture will directly determine the adaptability of the adaptive software in the running phase. Therefore, it is necessary to evaluate the adaptability of the architecture in the design stage, and modify the architect...

AI Technical Summary

Problems solved by technology

[0003] Existing research on architecture adaptability evaluation mainly has the following two deficiencies: First, the understanding of adaptability is too one-sided

However, there are two types of adaptation methods for adaptive software: structural adaptation and parameter adaptation. As the core of supporting software to achieve self-adaptation, the adaptation method of the architecture should also have two types of structural adaptation and parameter adaptation, so only focus on components and connectors changes cannot fully assess the suitability of the architecture
