【摘要】：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.
[Abstract]:The optimal timing control and reliability of data transmission systems with uncertain transmission time, transmission time and reception time are studied. The time series evolution model of uncertain data transmission system is established by using maximal plus algebra method. In this paper, the vector value function of data reception time parameter variable and the nonnegative solution of linear equations are introduced in the uncertain data transmission system. Under the condition that the data transmission time is taken from a given interval and the transmission time is not negative, The minimum value (the earliest receiving time) and the optimal solution of the data receiving time are obtained. Under the constraint condition that the data reception time is limited to a given interval, the maximum (the latest transmission time) and the optimal solution of the data transmission time are obtained. The reliable interval of uncertain data transmission system is introduced so that the data can be received on time after transmission at any time in this interval without the influence of transmission delay. In this paper, the existence criterion of reliable interval is given, and an effective algorithm for finding the maximum reliable interval is provided by introducing the interval of admissible solutions of the system of linear equations with maximum interval parameters.
