摘要: 用定量手段研究需求演化需要相关方法加以指导。利用排队论来分析需求变化请求从提出到实现的整个过程所具有的排队模型特征。在M/M/1/m/m假设之下,改进了现有需求成熟度的计算方法,并通过实例计算了该排队模型的特征指标,分析了这些数量对评价需求分析的效率及需求工程师的能力所具有的借鉴意义,并指出排队论在指导用定量手段研究需求变化管理上的作用。

Abstract: Abstract It needs methodology to study rectuirements evolution by quantitative methods. Based on ctueuing theory, this paper analyzed the process of requirements change rectuests and pointed out the characteristics of queuing models. The current method of calculating requirements maturity index was improved by M/M/1/m/m. An example shows that the quantities got from this ctueuing model have their meanings to evaluate the effectiveness of rectuirements analysis and the capability of requirements engineers. The funciton of queuing theory in guiding the management of requirements change was pointed out.
Key words: Requirements evolution, Requirements specification, Queuing theory
