Data and Queueing Analysis of a Japanese Arrival Flow
نویسندگان
چکیده
We analyze the east-bound arrival flow to Tokyo International Airport. Currently, aircraft are vectored in the en-route sector that is adjacent to the approach area, in order to meet a metering constraint. These vectors take place largely during the descent phase. In the future, arrival traffic shall be ‘synchronized’ in the cruise phase for less controller workload and more fuel efficiency. Our results are a good correspondence between a simple queueing model and empirical data, low average delays, and high prediction uncertainties of sector crossing times. This allows to identify strategies for future traffic synchronization that are tailored to the Japanese airspace.

Analysis of M/G/ 1 queueing model with state dependent arrival and vacation
This investigation deals with single server queueing system wherein the arrival of the units follow Poisson process with varying arrival rates in different states and the service time of the units is arbitrary (general) distributed. The server may take a vacation of a fixed duration or may continue to be available in the system for next service. Using the probability argument, we construct the ...
متن کاملQueueing Models and Stability of Message Flows in Distributed Simulators of Open Queueing Networks - Parallel and Distributed Simulation, 1996. Pads 96. Proceedings. Tenth Workshop on
In this paper we study message flow processes in distributed simulators of open queueing networks. We develop and study queueing models for distributed simulators with maximum lookahead sequencing. We characterize the “external” arrival process, and the message feedback process in the simulator of a simple queueing network with feedback. We show that a certain “natural” modelling construct for ...
متن کاملCapacity planning in the hospital queueing network with blocking: simulation-based optimization approach
Introduction: Hospital administrators have always faced the challenge of providing the best possible health services in a resource-limited environment. The patient flow throughout the hospital is affected by lack of the capacities that can lead to bed-blocking among the hospital units. In this research, the patient flow in the hospital is modeled as an open queueing network with blocking. Then,...

Determining and selecting an appropriate location to construct a hotel is one of the most challenging concerns which hotel industry investors are facing with. In this study we attempt to find a suitable response to this research/application need by a mathematical model using the queueing theory and the fuzzy logic. Therefore hotel, the reception system and travelers accommodations are formulate...
متن کاملMulti-Objective Lead Time Control in Multistage Assembly Systems (TECHNICAL NOTE)
In this paper we develop a multi-objective model to optimally control the lead time of a multistage assembly system. The multistage assembly system is modeled as an open queueing network, whose service stations represent manufacturing or assembly operations. The arrival processes of the individual parts of the product, which should be assembled to each other in assembly stations, are assumed to...
