[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.
