The paper researches the effect of storage-retrieval policies for multi-shuttle stacker,math model for its operation cycle,rack s length to width ratio of automated warehouse on operation cycle of multi-shuttle stacker under non-equal probability condition,and based on these effects,studies stacker s operation cycle and warehouse s storage-retrieval capacity,coming to a conclusio

Mathematical models of calculating SRM average single/double operation cycles are built under non-equal probability condition,The corresponding calculation program is developed with Visual C++language and successfully used to work out the operation cycles.

Satisfactory estimation of linear discrete periodic systems;

Energy Storage And Power Flow In Periodic System;

By using the method of Liapunov function,the existence and uniqueness of the periodic solution for some periodical systems is investigated and a sufficient condition is obtained.

In this paper, we employ the Fourier analysis method to obtain the necessary and sufficient conditions for higher order neutral linear periodical system with constant coefficients to have unique periodic solution, and improve the previous results.

In this paper, the existence and uniqueness of the periodic solution for some periodical system are studied by using the method of Liapunov function, a sufficient condition which guarantee the existence and uniqueness of the periodic solutions of the system is obtained.
