简介:我们考虑排队网络(QN的)与反馈,环由“聪明”的代理人漫步,能在QN节点根据他们的测量等待的时间选择他们的路由。这是一个理想化的模特儿讨论对一个服务供应商保持忠诚的顾客的动力学,如果他们的服务时间在批评阀值下面留下。为这些QN的家,我们证明交通流动可以展出典型地在多代理人系统遇到的集体模式。在简单网络拓扑学,突现的合作行为经由稳定的宏观的时间的摆动表明自己,由噪音现象的队列内容和稳定的同步。为大量控制参数,大数字的法律的内在的存在使我们能使用确定的进化法律到经分解描绘我们的多代理人系统的合作进化。特别地,我们学习服务者偶发地易于改变他们的平常的行为的失败的盒子。

简介:这份报纸为在无线通讯工业手机卡片计划的需求评价和分类提供一条有效、有用的途径。我们使用最大的可能性的评价基于历史的出售数据估计主要需求和每张手机卡片的替换概率。这个评价模型是非线性的,因此我们转变它到一个混合整数由对数的转变和piecewise的线性编程模型线性近似。根据评价结果,我们能做分类计划。考虑到手机卡片的资源是有限的,我们联合优化手机卡片计划的分类和数量。在数字学习,我们在中国把我们的途径用于一个大活动服务供应商并且发现我们的途径能增加这个活动服务供应商的收入23.69%。敏感分析证明活动服务供应商应该提供更多的分类当能被分到每家店的手机卡片的类型是有限的时,增加收入。
