The current negotiation models build use of agent technology more based on rational environment.However, real negotiation often influence in the irrational environment.To solve this problem, proposed a new bilateral negotiation model influence in the irrational environment.In this model, irrational environment through that the description of decision-makers' character, personal preferences and psychological advantage to simulation.While the negotiation process proposed by the consultative status as irrational environment, external influences.To reflect the irrational environment on the impact of negotiation, also proposed the effectiveness of assessment methods based on perturbation and environment dependent strategy.Simulation results show that the definition of irrational negotiation environment can better simulate the real situation, the use of utility assessment function and negotiation strategies, better reflect the influence of the irrational on decision-making.Result verification, negotiation model of proposed is effective.%针对当前协商模型中大多未考虑非理性因素影响的问题,提出一种非理性环境影响下的双边协商模型.在该模型中,通过对决策者性格特征MI、个性偏好W和心理优越度MS的描述模拟非理性环境,同时利用协商过程中的协商状态等作为对非理性环境的外部影响.为体现非理性环境对协商决策的影响,采用了基于扰动的效用评估方法和环境依赖的协商策略.仿真实验表明,定义的非理性协商环境能够较好地模拟真实情况;同时,利用效用评估函数和协商提议策略更好地体现了非理性环境对决策的影响.经验证,提出的协商模型是有效的.
