Analysis of Airport Security Screening Checkpoints using Queuing Networks and Discrete Event Simulation: A Theoretical and Empirical Approach
… utilized discrete event simulation (DES) and queuing networks to investigate the effects of baggage volume and alarm rate at the Security Screening Checkpoint (SSCP) of a small origin and destination airport. A Jackson queuing network was considered for a theoretical assessment to SSCP …

Modeling and Control of Queuing Networks: Applications to Airport Surface Operations
… In this thesis, we propose a new class of queuing network models of airport surface operations that are capable of capturing congestion at multiple locations, and that can account for the time-varying nature of demand and capacity. The proposed queuing models are based on point-wise steady …

Aerospace composite manufacturing cost models as geometric programs
… Programming (GP). A new formulation of a closed queuing network as a GP is presented to capture the crucial cost trade-offs between capacity and inventory. Additionally, GP models are presented for modeling unit processes in composite manufacturing and for modeling cost accounting metrics. …

Applications of Queuing Theory for Open-Pit Truck/Shovel Haulage Systems
… of fleet selection involves the application of queuing theory to the haul cycle. Queuing theory was developed to model systems that provide service for randomly arising demands and predict the behavior of such systems. A queuing system is one in which customers arrive for service, wait for …

Network design models for intermodal logistics
… explore the dynamics of intermodal hub-and-spoke networks, are presented. These models use transportation costs, fixed location costs, modal connectivity costs, modal transit times and service time requirements, for three modes of transportation: road, rail and air. The objective is to compare the …

Simultaneous Lot sizing and Lead-time Setting (SLLS)Via Queuing Theory and Heuristic search
… system model, which is based on open queuing network theory. Then, it optimizes lot size by using realistic estimates of WIP and the lead-time of different lots simultaneously for single-product, single-level bills of material. Experiments are conducted to compare the performance of …

The spares provisioning problem with parts inventory
… increases its difficulty. This is because the queuing network model which describes the system is a non-product-form network in the case of finite nonzero stocking policy, and specification of closed-form solutions is highly unlikely for such networks. In this dissertation, we present efficient …

Automatic Derivation of Performance Models in the Context of Model-Driven SOA
… specific model into a performance model (Layered Queuing Network in this case) which is then solved to produce the performance output results. A traceability model is used in PUMA4SOA to navigate between different kinds of models (i.e., UML, CSM and LQN) in order to propagate changes of properties …

A new approach in the transient analysis of ATM multiplexers with bursty sources
… in the steady-state analysis of a tandem queuing network with correlated arrivals. First we derive the steady-state joint generating function of the contents of the queues and the number of active sources. From this any moment of the queue length at each node can be extracted. In addition …

Scheduling algorithms for throughput maximization in time-varying networks with reconfiguration delays
… the control of possibly time-varying wireless networks under reconfiguration delays. Reconfiguration delay is the time it takes to switch network resources from one subset of nodes to another and it is a widespread phenomenon observed in many practical systems. Optimal control of networks has …

Asymptotic Analysis and Performance-based Design of Large Scale Service and Inventory Systems
… This system can be represented by a closed queuing network. Applications include fleet vehicles' repair and backup capacity, warranty services' staffing and spare items investment decisions. For these types of systems, customer satisfaction is essential; thus, the delays until replacements …
