On the basis of the overall strategy of “ becoming one of the world top 500 companies ” , set by the headquarters of china united telecommunications corporations ltd . ( china unicom ) , and urged by the new economic and market conditions , china unicom ( jilin ) implemented bpr in its operation , maintenance , and service ( oms ) system . with the continuous evolution of the bpr theory , bpr , tested by practice , has gradually shifted its focus from overall reengineering to optimization and improvement of business enterprises , reaching a more rational and more comprehensive stage with an increased operability and success rate . using “ the methodology of systematic redesign ” , a study on business process reengineering in the operation , maintenance and service system in china unicom ( jilin ) makes an analysis on the present process and , based on the present process , systematically creates a new process for oms system in china unicom ( jilin ) 本文以目前企业界非常关注的热点:业务流程再造( businessprocessreengineering ,简称bpr )在电信运营企业的运用为课题进行深入研究,在分析大型电信运营商运维体系所面临的挑战、运维理念变更的重要性和运维组织管理需要改革调整的必要性基础上,分析研究吉林联通运维服务体系管理流程的模式以及所存在的弊端,运用业务流程再造( bpr )理论对吉林联通运维体研究,文中以bpr理论中的‘系统化改造法’为指导思想, ‘业务流程再造7阶段模型’为理论模型对吉林联通运维服务管理体系进行流程再造,整合网络管理、资源管理、作业调度系统之间的关系。
For the problems of resource reserving plan and memory use efficiency , the author designs and implements a job scheduling system with dedicated job scheduling algorithm , and puts forward a special algorithm to estimate the memory usage value of the jobs whose memory usage are changing continuesly 为了解决资源保障计划和作业内存使用效率问题,作者设计并实现了一套专用的作业调度系统,制订了有针对性的作业调度算法,提出了对实际使用内存持续变化的运行作业的内存估计值算法。
Because of the defect of long running time and big complexity in the classical job - shop scheduling algorithm , the paper brought forward an intelligent optimization algorithm based on rule ; scheduling process is divided to primary process and optimization process . through the method of ahp ( analytical hierarchy process ) , the effect is researched between several rules and estimate . moreover , the results of ahp are used as a measurable standard to scheduling results 本文针对传统车间作业调度算法运行时间长,复杂度大的缺点,提出了基于规则的智能优化调度算法,将排序的过程分为初始排序与优化排序;基于多目标决策的层次分析方法,得出了各种规则与系统评价指标之间的影响度,其结论为生产计划方案的选择提供了定量的参考依据。
