简介：到期的日期引语并且安排是重要工具在MTO(make-to-order)环境与生产能力匹配需求。我们考虑安排在MTO环境操作的一个生产公司面对的问题的一份订单，在公司需要为顾客引用一个普通到期的日期的地方，并且同时控制顾客订单的处理时间(由分配额外的资源处理订单)以便在给定的截止时间前完成订单。目的是最小化早，缓慢，到期的日期任务和额外的资源消费的全部的费用。我们证明这个问题是NP难的，就算为控制处理时间的订单的费用重量是相同的。我们识别这个问题的几个polynomially可解决的盒子，并且开发一个分支和界限算法和三个禁忌搜索算法解决一般问题。我们然后进行计算实验评估他们以解决方案质量通常是有效的三个禁忌搜索算法和表演的性能。

简介：在这份报纸，我们与安装时间和多重假期认为BMAP/G/1是G队列。积极顾客和否定顾客的到达分别地跟随一个批Markovian到达过程(BMAP)和Markovian到达过程(地图)。当服务者正在工作时，一个否定顾客的到达在系统移开所有顾客。一旦系统倒空，服务器为一个假期离开并且被允许拿重复(多重)假期。由使用增补变量方法和审查技术，我们获得队列长度分布。我们也基于更新理论获得忙时期的平均数。

简介：我们认为连续评论容易腐烂(s，S)有由有限能力和一个单身的服务者的一个等待的大厅组成的一台服务设备的库存系统。我们假定顾客的二种类型，平常、否定，根据一个Markovian到达过程(地图)到达。Anordinary顾客加入队列，一个否定顾客把一个平常的顾客从队列移开而不是加入队列。在这篇论文采用的移动规则是RCE(从结束的一个顾客的移动)。单个顾客的单位需求在被假定有阶段类型分布的服务的一随机的时间以后满足。每个项目的生活时间和reorders的铅时间被假定是独立指数的分布。在系统和库存水平的顾客的数字的Thejointprobability分发为稳定的州的盒子被获得。各种各样的静止系统性能措施被计算，全部的期望的费用率是计算的。结果数字地被说明。
