Evaluation of army corps artillery ammunition supply systems via simulation
The purpose of this paper is to discuss the evaluation of different alternatives for the implementation of Turkish army corps artillery ammunition supply system. The objective is to see whether the alternative systems ...
Averaging in Markov models with fast Markov switches and applications to Queueing models
An approximation of Markov type queueing models with fast Markov switches by Markov models with averaged transition rates is studied. First, an averaging principle for two-component Markov process (x n (t),ζ n (t)) is ...
An adaptive bayesian replacement policy with minimal repair
(Institute for Operations Research and the Management Sciences (INFORMS), 2002)
In this study, an adaptive Bayesian decision model is developed to determine the optimal replacement age for the systems maintained according to a general age-replacement policy. It is assumed that when a failure occurs, ...
A global error bound for quadratic perturbation of linear programs
We prove a global error bound result on the quadratic perturbation of linear programs. The error bound is stated in terms of function values.
Approximation of multiserver retrial queues by means of generalized truncated models
It is well-known that an analytical solution of multiserver retrial queues is difficult and does not lead to numerical implementation. Thus, many papers approximate the original intractable system by the so-called ...
Self-Scaled Barrier Functions on Symmetric Cones and Their Classification
Self-scaled barrier functions on self-scaled cones were axiomatically introduced by Nesterov and Todd in 1994 as a tool for the construction of primal-dual long-step interior point algorithms. This paper provides firm ...
Operation-based flowtime estimation in a dynamic job shop
In the scheduling literature, estimation of job owtimes has been an important issue since the late 1960s. The previous studies focus on the problem in the context of due date assignment and develop methods using aggregate ...
Diffusion approximation in overloaded switching queueing models
The asymptotic behavior of a queueing process in overloaded state-dependent queueing models (systems and networks) of a switching structure is investigated. A new approach to study fluid and diffusion approximation type ...
Linear huber M-estimator under ellipsoidal data uncertainty
The purpose of this note is to present a robust counterpart of the Huber estimation problem in the sense of Ben-Tal and Nemirovski when the data elements are subject to ellipsoidal uncertainty. The robust counterparts are ...
Dynamic lot sizing and tool management in automated manufacturing systems
The overall aim of this study is to show that there is a critical interface between the lot sizing and tool management decisions, and these two problems cannot be viewed in isolation. We propose "ve alternative algorithms ...
