Under the hypothesis of model,some probable characteristics such as transition probability,stationary distribution,staying time distribution were discussed(To date,we have not seen the application of the model in shooting effectiveness being discussed in Any public references).

ln statistical equilibrium,the author obtains the equilibrium distribution of queue length and that of waiting queue length,the average of queue length and that of waiting queue length as well as the equilibrium distribution of waiting time and that of staying time, the average of waiting time and that of staying time.

Furthermore , the successive sojourn time of customer C in ith station (i=1,2,.

The exhaustive service polling system with bulk arrival,and the distribution and mean of the queue length and the cycle time,service time and interval time of the server and the distributions of sojourn times are studied.

In order to serve much more mobile stations in heterogeneous hierarchical wireless networks, a dynamic load balancing algorithm based on sojourn time was proposed.

By discussing the relations between transition probabilities and expected duration of stay and working intensity and losing intensity,this paper obtains a result that working transition probabilities and expected duration of stay and working intensity have the same increasing or decreasing properties,but losing transition probability is just contra.
