We view each station in a Jackson network as a queue of tasks, of a particular type, which are to be processed by the associated specialized server. A complete pooling of queues, into a single queue, and servers, into a single server, gives rise to an M/PH/1 queue, where the server is flexible in the sense that it processes all tasks. We assess the value of complete pooling by comparing the ste...

We use a sample-path technique to derive asymptotics of generalized Jackson queueing networks in the fluid scale; that is, when space and time are scaled by the same factor n. The analysis only presupposes the existence of long-run averages and is based on some monotonicity and concavity arguments for the fluid processes. The results provide a functional strong law of large numbers for stochast...

Nonstationary queueing networks are notoriously difficult to analyze and control. One reason is that steady state analysis and techniques are not useful since the model parameters in practice are not constant and depend on time. In this work, we analyze two optimal control problems for nonstationary Jackson networks with abandonment where our main goal is to optimally control the number of serv...

Most allocation rules for network games presented in the literature assume that the network structure is fixed. We put explicit emphasis on the construction of networks and examine the dynamic formation of networks whose evolution across time periods is stochastic. Time-series of networks are studied that describe processes of network formation where links may appear or disappear at any period....

Here we research the univariate quantitative approximation, ordinary and fractional, of Banach space valued continuous functions on a compact interval or all real line by quasi-interpolation neural network operators. These approximations are derived establishing Jackson type inequalities involving modulus continuity engaged function its high order derivative fractional derivatives. Our operator...

involving the rise of the health centre and the health care team. In terms of precursors, these ideas went back at least to 1920; in terms of operational application, the modernization of general practice cannot really be said to have begun before 1966. It may even be argued that the characterization of modern general practice-"a network of surveillance that discovered, identified and monitored...
