Simulation of queueing systems with many stations and of queueing networks using copulas [PDF]
In this paper we will generate queueing systems with c stations where the inter-arrival time and the c service times depend through a c+1 copula C. We will consider two models: first when the customer does not know the order of service times for the free

Quality and Reliability Engineering International, EarlyView.ABSTRACT This study examines how Lean Six Sigma (LSS) currently functions in the U.S. textile and apparel industry after years of adoption and use. Moving beyond isolated project‐level evidence, this study investigates whether LSS has been implemented as an organizational capability and integrated into the corporate culture, adapted to textile‐specific

Integrated service resource reservation using queueing networks theory
IET Networks, 2014 This study analyses multi‐server multi‐service queueing networks with service protection. To guarantee each service a certain quality‐of‐service and at the same time ensure high utilisation of servers, a minimum capacity is reserved each service.

Healthcare queueing models. [PDF]
Healthcare systems differ intrinsically from manufacturing systems. As such, they require a distinct modeling approach. In this article, we show how to construct a queueing model of a general class of healthcare systems.

Path‐Based Deep Reinforcement Learning for On‐Board Routing in Satellite Constellation Networks
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT Efficient usage of available network resources is a crucial factor for broadband services in interconnected satellite constellations. To meet required quality of service standards under heavy network loads, it is essential to optimize traffic distribution among the intersatellite links. To address this challenge, we propose an adaptive traffic

Queueing Theory And Telecommunication
, 2013 A good telecommunication networks can be represented as queueing networks with state-dependent arrival rates and service rates. We provide necessary and sufficient conditions for such queueing networks to be sense that the steady-state distribution ...

Dynamic Cell Division for Interference Management in Satellite Direct‐to‐Cell Systems
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT Direct‐to‐cell (D2C) connectivity enables future non‐terrestrial networks to provide service directly to standard terrestrial user equipment (UE) when terrestrial networks (TN) are unavailable. In this work, the satellite system is considered as a secondary network that supplements existing TN coverage while minimizing interference to the ...

Approximate analysis of blocking queueing networks with temporal dependence [PDF]
, 2011 In this paper we extend the class of MAP queueing networks to include blocking models, which are useful to describe the performance of service instances which have a limited concurrency level.

Restoring End‐to‐End Transport With QUIC on Satellite Paths
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT Slow Start is a key congestion control mechanism used to assure a safe response to overload of a path across the Internet. This mechanism increases the startup time taken by the sender to reach the capacity available across the path. The benefit becomes significant on paths with a high bandwidth‐delay product.
