由于预算期限和上市时间的限制，必须对软件需求进行优先级排序。需求优先级排序的结果是在软件开发过程中需要首先考虑的需求的顺序。为了实现高质量的软件系统，在确定优先级的过程中，必须同时考虑功能需求和非功能需求。虽然到目前为止已经提出了几种需求优先级排序方法，但在优先级排序阶段，没有提出一种特定的方法或方法来考虑功能和非功能需求。在本文中，我们提出了一种方法，其目的是集成的过程中优先功能和非功能性的需求。应用所提出的方法的结果产生了两个单独的功能和非功能需求的优先级列表。所提出的方法的有效性进行了评估，通过实证实验，旨在比较该方法与两个国家的最先进的方法，层次分析法（AHP）和混合评估方法（HAM）。结果表明，我们所提出的方法优于AHP和HAM的实际时间消耗方面，同时保持我们所提出的方法在一个高层次的协议所产生的结果相比，其他两种方法的质量。
Due to the budgetary deadlines and time to market constraints, it is essential to prioritize software requirements. The outcome of requirements prioritization is an ordering of requirements which need to be considered first during the software development process. To achieve a high quality software system, both functional and nonfunctional requirements must be taken into consideration during the prioritization process. Although several requirements prioritization methods have been proposed so far, no particular method or approach is presented to consider both functional and nonfunctional requirements during the prioritization stage. In this paper, we propose an approach which aims to integrate the process of prioritizing functional and nonfunctional requirements. The outcome of applying the proposed approach produces two separate prioritized lists of functional and non-functional requirements. The effectiveness of the proposed approach has been evaluated through an empirical experiment aimed at comparing the approach with the two state-of-the-art-based approaches, analytic hierarchy process (AHP) and hybrid assessment method (HAM). Results show that our proposed approach outperforms AHP and HAM in terms of actual time-consumption while preserving the quality of the results obtained by our proposed approach at a high level of agreement in comparison with the results produced by the other two approaches.
