We develop Generalized Stochastic Petri Net models for several priority queueing disciplines. The building blocks of these models are explained and many variants are easily derivable from them. We then combine these b...

When building a model for degradable computer syrtems, it ir not sufficient to merely quantify reliability and performance measures. There indicer must be mathematically sound if they we to be wed to design such syste...

We consider a voice/data integrated local area communication system. Due to the high suitability of CSMAKD protocols for data communication and the existence of real time voice delay constraints we consider a hybrid T...

The HYPERchannel communication network configured around one to four channels is considered. We develop a queueing model which characterizes the network performance as a function of the number of channels, the channel...

An analytic performance modeling case study of a complex command and control computer system -is presented. A queueing network model of the system was developed and validated. Features of the model found to be critica...

We present a model for distributed systems with failing components. Each node may fail and during its recovery the load is distributed to other nodes that are operational. The model assumes periodic checkpointing for ...

Database referencing behaviour is analyzed with respect to locality features. The analysis is based on database reference strings collected from several runs of typical batch programs accessing a real database. Locali...

A Multiclass Queueing Network model (MQN) is partitioned into a set of disjoint subnetworks. Population constraints are applied to each subnetwork such that within each subnetwork each population chain is either subje...
