In the study of quasi-birth-and-death (QBD) processes, the first passage probabilities from states in level one to the boundary level zero are of fundamental importance. These probabilities are organized into a matrix, usually denoted by G. The matrix G is the minimal nonnegative solution of a...

We consider the output processes of some elementary queueing models such as the M/M/1/K queue and the M/G/1 queue. An important performance measure for these counting processes is their variance curve v(t), which gives the variance of the number of customers in the time interval [0, t]. Recent...

The business connections between Beijing, Hong Kong and Shanghai and other major world cities are investigated using the interlocking network model based upon the location strategies of advanced producer service firms. This approach emphasises non-hierarchical relations between cities. A key new...
