On the Service Models for Dynamic Scheduling of Multi-Class Make-to-Stock Systems



On the service models for dynamic scheduling of multi-class base-stock controlled systems
Kat, Bora; Avşar, Zeynep Müge; Department of Industrial Engineering (2005)
This study is on the service models for dynamic scheduling of multi-class make-to-stock systems. An exponential single-server facility processes different types of items one by one and demand arrivals for different item types occur according to independent Poisson processes. Inventories of the items are managed by base-stock policies and backordering is allowed. The objective is to minimize base-stock investments or average inventory holding costs subject to a constraint on the aggregate fill rate, which is...
On the parametric and nonparametric prediction methods for electricity load forecasting
Erişen, Esra; İyigün, Cem; Department of Industrial Engineering (2013)
Accurate electricity load forecasting is of great importance in deregulated electricity markets. Market participants can reap significant financial benefits by improving their electricity load forecasts. Electricity load exhibits a complex time series structure with nonlinear relationships between the variables. Hence, new models with higher capabilities to capture such nonlinear relationships need to be developed and tested. In this thesis, we present a parametric and a nonparametric method for short-term ...
On the Smoothing Factor for Rate Adaptation in IEEE 802.11b/g Mobile Multi-Hop Networks
Zhou, Jinglong; Onur, Ertan; Jacobsson, Martin; Niemegeers, Ignas (2009-01-01)
IEEE 802.11b/g networks support multiple rates and rate adaptation mechanisms provide the ability to select the adequate rate intelligently. Prior work on the rate-adaptation focuses on stationary scenarios, such as mesh networks. The effect of the smoothing of the rate adaptation is not a well-studied topic in the mobile scenarios such as IEEE 802.11 multi-hop networks. In this paper, we use an experimental method to evaluate the one-hop performance and the routing decisions of a well-known rate adaptation...

On the retrial and redial phenomena in GSM networks
Onur, Ertan; Ersoy, C; Caglayan, MU (2000-01-01)
GSM operators work with call data that include retrials and redials as well. Based on these inflated, virtual call attempt statistics, it appears that enormous demands are put on the available spectrum. In this paper, we develop simple models to estimate the expected number of retrials and redials per original call attempt, which is used to determine the effective load and the number of traffic channels required to meet the grade of service. It is shown that significantly fewer channels are capable of handl...
