工作总时差计算方法的探讨
In this paper, algorithms of total float time and free float time about activities in a fuzzy network are presented, and the method using activities total float time to determine critical activities and path in a fuzzy network is given.
提出了模糊网络中工序总时差和单时差的算法，同时给出了关键工序和关键路线的工序总时差判别方法。
The basic principle of total time difference is analyzed,and a new thought of weight earned value is put forward.
指出了传统挣得值分析方法在项目进度评测中存在的不足,在分析任务总时差的性质的基础上引入了含权挣得值的概念来解决这个问题,并给出了含权挣得值的计算公式和分析步骤。
Under the condition of window size (w)equaling to one and single data unit acknowledging,this paper analyzes the performance of virtual connection OOL and LOO type laying protocol networks taking into account error- correcting transmission,and obtains the total delay expression for data unit transmission.
在窗口大小w=1,单数据单元确认的条件下,文章考虑纠错再送,对虚拟连接OOL、LOO型分层协议网络进行性能分析,得到了数据单元传输总时延的表达式,最后对数据单元的传送总时延进行了模拟实验及分析。
The performance is analysed in terms of data unit transmission total delay, and based on this we give the curves that transmission effciency moves with data unit length and bit error rate changing.
这里性能分析以数据单元传送总时延为依据，并在此基础上得出传送效率随数据单元长度、误码率变化的曲线。
