Special issue on “Nonlinear continuous optimization”
(Springer, 20150215)This special issue contains five papers dedicated to Nonlinear Continuous Optimization. All these contributions went through a strict and detailed refereeing process, and were revised according to the strict high standards ... 
Facility location and capacity acquisition : an integrated approach
(John Wiley & Sons, 1995)The facility location and capacity acquisition decisions are intertwined, especially within the international context where capacity acquisition costs are location dependent. A review of the relevant literature however, ... 
Asymptotic analysis of nonhomogenous hierarchical Markov processes and applications in models of the consolidation of queueing systems
(American Mathematical Society, 1998)Limit theorems for nonhomogenous in time hierarchical Markov processes admitting the consolidation of states are studied. Noiton of quasiMarkov processes is introduced. The theorem on asymptotic consolidation in the class ... 
Dynamic lot sizing and scheduling in cellular manufacturing systems using hybrid simulation analytic model
(International Journal of Industrial Engineering, 1995)In most of the production systems, lotsizing and scheduling decisions are made at different levels of hierarchy; although there is a strong interaction between these decisions. Furthermore, most of the existing models do ... 
A new finite continuation algorithm for linear programming
(Society for Industrial and Applied Mathematics, 1996)We describe a new finite continuation algorithm for linear programming. The dual of the linear programming problem with unit lower and upper bounds is formulated as an f\ minimization problem augmented with the addition ... 
Parameter selection in genetic algorithms
(International Institute of Informatics and Cybernetics, 2004)In this study, we provide a new taxonomy of parameters of genetic algorithms (GA), structural and numerical parameters, and analyze the effect of numerical parameters on the performance of GA based simulation ... 
Convergence of switching reward processes
(American Mathematical Society, 2001)We study the convergence in the Skorokhod Jtopology of switching reward processes constructed by sums of conditionally independent random variables or by processes with conditionally independent increments on the trajectories ... 
Some Markovian queuing retrial systems under light  traffic conditions
(Kluwer Academic PublishersPlenum Publishers, 2001)The asymptotic behavior of the time of the first loss of a demand in Markovian singlechannel and multichannel queuing retrial systems with a finite buffer and an external Markovian environment is analyzed. Two cases are ... 
On the Hajek projection for truncated and censored data
(Scientific Publishers, 1993)Large sample properties of the productlimit estimators for truncated or censored data are usually achieved via the empirical cumulative hazard function estimators. Hajek projection of the empirical cumulative hazard ... 
Residual lifetime distribution and its applications
(Pergamon Press, 1994)Let T be a continuous positive random variable representing the lifetime of an entity. This entity could be a human being, an animal or a plant, or a component of a mechanical or electrical system. For nonliving objects ... 
A stability concept for zero  one knapsack problems and approximation algorithms
(Taylor & Francis, 1995)The concept of reducing the feasible range of decision variables or fixing the value of the variables is extended for the knapsack problem to include sets of variables. The ease of fixing these variables is measured by a ... 
Performance evaluation models for single  item periodic pull production systems
(Palgrave Macmillan, 1996)A number of pull production systems reported in the literature are found to be equivalent to a tandem queue so that existing accurate tandemqueue approximation methods can be used to evaluate such systems. In this study, ... 
Scheduling with neural networks : A review of the literature and new research directtions
(Taylor & Francis, 1998)Artificial neural networks ( ANNs) attempt to emulate the massively parallel and distributed processing of the human brain. They are being examined for a variety of problems that have been di cult to solve with current ... 
On the distribution of throughput of transfer lines
(Palgrave Macmillan, 2000)Transfer lines simply characterise the interrelationship of manufacturing stages with their buffers and they are used to model the key features of such manufacturing environments with simplifying assumptions. There is a ... 
A GIS ‐ based framework for hazardous materials transport risk assessment
(WileyBlackwell Publishing, 2001)This article presents a methodology for assessment of the hazardous materials transport risk in a multicommodity, multiple origin – destination setting. The proposed risk assessment methodology was integrated with a ... 
Switching stochastic models and applications in retrial queues
(SpringerVerlag, 1999)Some special classes of Switching Processes such as Recurrent Processes of a SemiMarkov type and Processes with SemiMarkov Switches are introduced. Limit theorems of Averaging Principle and Diffusion Approximation types ... 
Routingbased reactive scheduling policies for machine failures in job shops
(Taylor & Francis, 2001)A scheduling and control system can be viewed as a vital component of modern manufacturing systems that determines companies’ overall performance in their respective supply chains. This paper studies reactive scheduling ... 
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 agereplacement policy. It is assumed that when a failure occurs, ... 
Approximation of multiserver retrial queues by means of generalized truncated models
(Springer, 2002)It is wellknown 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 socalled ...
