Abstract: To solve the problems of the existing proposal generating strategy mechanism in dynamic issues area, a new strategy mechanism was presented. In the strategy mechanism, the design of the META strategy was simplified by a new integration of existing strategy mechanism; and the existing trade-off algorithm was improved to be adapted to the issue dynamic changes in negotiation effectively. The experiments show that, facing issue dynamics problems, the proposed strategy mechanism guarantees the negotiation time as well as the joint gain, so it shows an excellent adaptability to issue dynamics in negotiation.

摘要： 针对现有协商策略机制在处理动态议题方面的不足，提出了一种新的提议生成策略机制。一方面，该机制通过对现有机制的重新整合简化了META策略的设计；另一方面，对新机制中引入的折中算法进行改进，使之有效适应了协商过程中的议题动态变化。实验表明，该策略机制在议题动态变化时既保证了协商成功时间，又保证了协商双方联合效用，在议题动态性方面表现了良好的适应能力。
