The average single task cycle of stacker crane can be used to get the equivalent slot of single task cycle,which provides the gist to design and run automated storage retrieval system effectively.

The average period of nonlinear autonomous systems is calculated, and it is found that the average period of the system almost do not vary with parameters changing .

Firstly, we set a barrier to the underlying asset price under the assumption of common Asian options, the average period begins at the first time when the underlying price hits the barrier.

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.

Study of method for complex image coregistration of InSAR based on averaged periodogram;
