中文摘要：

提出一种将涉众为中心和敏捷方法有机结合的敏捷需求建模方法。所有软件系统需求获取以涉众为中心,基于涉众扩展特征建立涉众Power/Interest分布图来确定涉众优先级,并用优先级处理不同涉众之间的需求冲突,根据涉众为中心的敏捷需求方法,提出敏捷需求实践方法,融合敏捷方法的短周期、演化、增量、迭代、重构、反馈机制,使软件系统需求建模过程更加完备、精确、高效、快捷,用双变迁Petri网DTPN为该方法建立形式化敏捷需求模型,为软件系统需求建模提出了一种新的方法。

英文摘要：

Present a stakeholder-centered and agile requirements modeling methodology.All software system requirements are gathered from stakeholder-centered methodology.Stakeholders＇ priorities are decided by the Power/Interest distributed map based on stakeholder extended characteristics.Requirements confliction in stakeholders are solved by priority.Agile requirements practice methodology is presented according to stakeholder-centered agile requirements methodology.It involves short cyclic,evolution,increment,iteration,refractory and feedback of agile methodology,makes software system requirements more complete,exact,efficient and shortcut.The formal requirements model is constructed with DTPN for the methodology.It presents a new methodology for software system requirements modeling.
