摘要
将多属性群决策方法应用到需求优先级排序中,提出了一种自适应调整的需求评价方法。将基于价值的需求工程理论和自适应方法学集成到需求优先级排序过程中,选取需求的重要性、风险和实现成本作为评价属性,在各专家主观决策的基础上,以个体决策结果和群体决策结果的偏离程度作为调整的依据,对个体决策结果进行调整,进而得到新的群体决策结果。给出算例说明了该方法的可行性。
This paper applied the theory of multi-attribute group decision-making in the process of requirements prioritization and proposed an adaptive adjust prioritizing method. This method integrates the value-based requirements engineering theory and adaptive methodology into the process of requirements prioritization. The requirements＇ value, risk and cost are selected as the decision attributes. Based on the experts＇ subjective decision, in light of the deviation level of the results of individual decision and group decision, the method is used to calculate the adjusted individual decision results, based on which the new group decision result is obtained. Finally, the method proposed in this paper is illustrated as feasible by a numerical example.
