一个用于解决需求不一致的纳什均衡策略选取方法

摘要

即使在需求说明形成之后，项目涉众要求变更需求的情形一样屡见不鲜，对新需求的管理以及需求不一致的处理显得十分重要。将博弈论中纳什均衡的相关知识应用到需求协商，定义了协商时博弈双方的策略意愿值，给出了纯策略与混合策略纳什均衡策略的选取方法，并实现了该策略选取工具，为协商函数提供了所需的策略组合方案。%Even after the establishment of the requirements specification,it often occurs that the project’stakeholders change their requirements,which makes the management of new requirements and treatment of inconsistencies very important.This pa-per applied the relevant knowledge of Nash equilibrium of game theory to the requirements negotiation works,defined the strate-gy expectation value of the two participants in the negotiation,and gave each Nash equilibrium strategy choosing method of pure strategy and mixed strategy.It implemented the strategy choosing tool at last,which provided strategy choosing solutions for ne-gotiation function.
