简介：这篇论文在一所突尼斯的大学里在一个机构处理功课Timetabling问题。我们介绍一个启发式的过程为任何节的每个分部的不同的组进行的所有讲课和教程构造一张可行时间表。我们用所有特定的难、软的限制的一张表描述timetabling问题。我们分别地用相应于讲课和教程的二进制变量的二个集合作为一套线性限制提出这个问题。这启发式在突尼斯为经济的学院和斯法克斯的管理科学的一个分部与真实数据被说明，并且产生时间表与手工地产生的那些相比。另一完整的节的结果证实了好质量求婚启发式什么时候与手工制作的答案相比。

简介：与谈论气候的世界，变化，美国(美国)，中国和印度宣布了他们的碳排放减小目标。这三个国家完成他们的目标，重要问题产生例如将是完成那些目标的年度排放减小努力的，它将花费多少并且什么将是经济效果。这份报纸把中国和印度的碳紧张减小目标放进和美国的绝对排放减小目标一样的非线性的模型到最佳的排放控制策略和联系总数为在一年2020完成那些目标花费了的份量上学习，并且估计并且比较三个国家的最小化的全部的费用到达他们的目标。我们总数花费了让美国完成它的排放减小目标的结果表演以绝对数量比中国和印度的那些大。以到GDP的全部的费用的比例，然而，中国和印度比率比美国的显著地大，显示为象中国和印度那样的发展中的国家，排放减小目标的成就需要相对更大的努力。

简介：在计划的以前的撤退流动，最佳的动态交通赋值SO-DTA没考虑外长的费用的一个系统由潜在的交通事故引起了。因为下游的车辆经验丰富的事故相关的延期，一个交通事故，可能由于交通拥挤发生，将影响一个撤退过程。这份报纸建立概括系统费用在合并旅行时间和事故相关的延期的一个基于安全的SO-DTA线性编程模型。目标是在房间传播安装下面最小化概括系统费用。而且，作者提供认为两个是决定制造者和撤离者的线路选择行为的目的战略指导信息。算术地，作者建议一个非强迫的非线性的编程模型瞄准了最小化在基于安全的流动和随机的真实世界的撤退流动之间的差距，到提供战略旅行时间信息在可变消息符号VMS上被出版。在案例研究，作者发现基于安全的SO-DTA模型能减少拥挤并且改进撤退效率；随机的真实世界的撤退流动，由战略信息指导了，能接近基于安全的流动。
