【摘要】：软件非功能需求的实现涉及软件质量这一重要问题,非功能需求的满足程度,直接影响软件质量的满足程度.针对一直以来对软件质量的一贯重视以及软件非功能需求权衡的重要性,借鉴微观经济学领域的生产理论、替代弹性原理和线性规划方法,提出了软件非功能需求权衡代价分析方法并开发了辅助工具.首先,对项目组前期完成的可信软件非功能需求可满足性分析方法进行改进,提出了利益相关者通过协商获取非功能需求评估数据的方法,建立了非功能需求本体概念并构建本体知识库;针对实现非功能需求的策略,使用前期已完成的策略推理方法,对推理产生矛盾的策略提出权衡代价分析方法;通过分析策略实施代价,为软件开发及演化提供具有实际可操作的权衡决策依据,从更加符合产业化需要的角度解决软件非功能需求权衡问题;最后,基于可信第三方认证中心软件案例的维护及演化需要,对推理出矛盾的策略进行权衡代价分析,并给予决策建议,说明所提出方法的可行性.
[Abstract]:The realization of non-functional requirements of software involves the important problem of software quality, the degree of satisfaction of non-functional requirements, Aiming at the importance of software quality and the importance of software non-functional demand tradeoff, this paper draws lessons from the production theory in the field of microeconomics to replace the principle of elasticity and linear programming. In this paper, the cost analysis method of software non-functional requirement tradeoff is put forward and an assistant tool is developed. Firstly, we improve the method of reliability software non-functional requirement satisfiability analysis, which is completed by the project team in the early stage. This paper proposes a method of obtaining non-functional needs assessment data through negotiation, establishes the concept of non-functional requirements ontology and constructs an ontology knowledge base, and uses the pre-completed policy reasoning method to realize the non-functional requirements. This paper presents a trade-off cost analysis method for inferential strategies, and provides a practical basis for tradeoff decision making for software development and evolution by analyzing the implementation costs of the strategies. Finally, based on the need of maintenance and evolution of software cases of trusted third-party certification center, the paper analyzes the trade-off cost of reasoning contradictory strategies. And gives the decision suggestion, explains the feasibility of the proposed method.
