We develop and analyze a multiaccess communi-In this paper we present an analysis of a system with just cation model over the additive Gaussian noise channel. The enough complexity to exhibit both aspects of a multiaccess framework is information-theoretic; nonetheless it also incorpo-problem. In the analysis we use tools borrowed from both rates some queuteing-theoretic aspects of the problem....

In typical validations of computer performance models, analysist interpret the ptja) of queueing networks as time-proportions during which a given network state n is observed. They parameterize performance calculations with directly measured device service time functions and job device visit counts. Three operational assumptions constitute a minimal set of assumptions for calculating these p(n)...

Ghaffarzadegan and Larson (2018) contend that “many traditional operations research (OR) models can be improved by including feedback processes, as is commonly done in system dynamics (SD) p. 327” modelers build better combining the strengths of both modeling schools. Focusing mainly on queueing theory a fundamental building block Operations Research, they provide compelling examples supporting...

For given integers $n$ and $d$, both at least 2, we consider a homogeneous multivariate polynomial $f_d$ of degree $d$ in variables indexed by the edges complete graph on vertices coefficients depending cardinalities certain unions edges. Cardinaels, Borst van Leeuwaarden (arXiv:2111.05777, 2021) asked whether $f_d$, which arises model job occupancy redundancy scheduling, attains its minimum ov...

Abstract Agile systems, like the Kanban and Scrum frameworks, are built on assumptions of sustainability stability, however, there is little empirical evidence whether such systems stable in practice or not. Therefore, this study we aim to inspect stability by leveraging concept described Queueing Theory. We define a novel metric, Stability Metric, as way assessing queueing especially systems. ...

In this paper, we study a discrete-time first-comefirst-served queueing system with a single server and two types (classes) of customers, where the (average) service time of a customer is longer if its type differs from the type of the preceding customer. As opposed to traditional literature, the different types of customers do not occur randomly and independently in the arrival stream: we incl...
