Optimal control of traffic signal in "big unit";

“大路口”交通信号的优化控制

Aiming at how to build the construction control network of Shen-Da highway rebuilding project,this paper put forward making use of GPS to build plane control network,developing coordinate conversion software,and analyzing its statistical precision.

针对如何建立沈大路施工控制网的问题,平面控制采用GPS定位技术,编制坐标换算软件,并对其精度进行了统计分析。

The sets of the maximum path are gained from the algorithm,with the restriction of job running time,the subtasks are concentrative mapped into cheap resources so that the algorithm can save comput.

由于现有算法在网格环境下不能很好地解决资源有偿服务和满足用户的QoS需求间的问题,该文通过综合考虑作业中任务之间的优先关系,给出费用-时间优化的i-DAG调度算法,在保证作业时间期限的条件下,利用所求的最大路径,最大程度上将任务集中映射并映射到较便宜的资源上,减少了作业的计算开销和通信开销。
