研究数据发射时间、传输时间、接收时间不确定的数据传输系统时序的最优控制与可靠性.运用极大–加代数方法,建立不确定数据传输系统的时序演化模型.引入不确定数据传输系统的数据接收时间参变量向量值函数和极大–加线性方程组的非负解,在数据传输时间取自给定区间且发射时间非负的约束条件下,求得数据接收时间的最小值(最早接收时间)和最优解;在数据接收时间限制于给定区间的约束条件下,求得数据发射时间的最大值(最晚发射时间)和最优解.引入不确定数据传输系统的可靠区间,以使数据在这一区间内的任一时刻发射后,均可被按时接收,而免受传输延迟的影响.引入区间参数极大–加线性方程组的容许解区间,给出可靠区间存在性判据,并提供求最大可靠区间的一个有效算法.
The optimal control and reliability of the timing of data transmission system with data transmission time, transmission time and reception time are studied.Using maximal-additive algebra method, the time evolution model of uncertain data transmission system is established.Uncertain data transmission system , The minimum value of the data reception time is obtained under the condition that the data transmission time is taken from a given interval and the transmission time is non-negative The earliest receiving time) and the optimal solution, the maximum value (the latest transmitting time) and the optimal solution of the data transmitting time are obtained under the constraint that the data receiving time is limited to a given interval. The reliability of the introduction of the uncertain data transmission system Interval so that the data can be received on time after being transmitted at any time in this interval without being affected by the transmission delay.Improved the interval parameter maxima- Admissible interval of the linear system of equations, gives a reliable interval Existence criterion, and provide an efficient algorithm to find the most reliable interval.
