Asymptotic analysis of stochastic models of hierarchic structure and applications in queueing models
(Notable Pubns, 1998)A class of switching stochastic systems with hierarchic state space working in different scales of time ( slow and fast) that are adequate mathematical models at the analysis and modelling of various classes of computing ... 
The asymptotic properties of estimates of the parameters of nonlinear time series
(Springer, 2000)Asymptotic properties of nonlinear time series parameter estimators constructed on trajectories of stochastic systems under stationary and transient conditions are studied with the use of the leastsquares method. The ... 
Asymptotically optimal Bayesian sequential change detection and identification rules
(2013)We study the joint problem of sequential change detection and multiple hypothesis testing. Suppose that the common distribution of a sequence of i.i.d. random variables changes suddenly at some unobservable time to one of ... 
Auction based scheduling for distributed systems
(International Institute of Informatics and Systemics, 2006)Businesses deal with huge databases over a geographically distributed supply network. When this is combined with scheduling and planning needs, it becomes too difficult to handle. Recently, Fast Consumer Goods sector tends ... 
Automated robotic assembly line design with unavailability periods and tool changes
(Inderscience Publishers, 2016)We focus on an assembly line design problem of a fully automated robotic spotwelding line. Different from existing studies, we take the prescheduled unavailability periods, such as lunch and tea breaks, into account ... 
Averaging in Markov models with fast Markov switches and applications to Queueing models
(Springer, 2002)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 twocomponent Markov process (x n (t),ζ n (t)) is ... 
Averaging methods for transient regimes in overloading retrial queueing systems
(Elsevier, 1999)A new approach is suggested to study transient and stable regimes in overloading retrial queueing systems. This approach is based on limit theorems of averaging principle and diffusion approximation types for socalled ... 
Backtracking and exchange of information: methods to enhance a beam search algorithm for assembly line scheduling
(Elsevier, 2008)Beam search (BS) is used as a heuristic to solve various combinatorial optimization problems, ranging from scheduling to assembly line balancing. In this paper, we develop a backtracking and an exchangeofinformation (EOI) ... 
Balancing of Utype assembly systems using simulated annealing
(Taylor & Francis, 2001)The paper presents a new simulated annealing (SA)based algorithm for the assembly linebalancing problem with a Utype con®guration. The proposed algorithm employs an intelligent mechanism to search a large solution space. ... 
A beam search algorithm to optimize robustness under random machine breakdowns and processing time variability
(Institute of Industrial Engineers, 2007)The vast majority of the machine scheduling research assumes complete information about the scheduling problem and a static environment in which scheduling systems operate. In practice, however, scheduling systems are ... 
Beam search based algorithm for scheduling machines and AGVs in an FMS
(Institute for Industrial Engineers, 1993)This paper presents a beam search based scheduling algorithm for a random FMS. The proposed algorithm considers finite buffer capacity, routing and sequence flexibilities and generates machine and AGV schedules in varying ... 
A beam searchbased algorithm and evaluation of scheduling approaches for fexible manufacturing systems
(Taylor & Francis, 1998)This paper presents a new algorithm for the flexible manufacturing system (FMS) scheduling problem. The proposed algorithm is a heuristic based on filtered beam search. It considers finite buffer capacity, routing and ... 
Benders decomposition algorithms for two variants of the single allocation hub location problem
(Springer, 2019)The hub location problem (HLP) is a special type of the facility location problem with numerous applications in the airline industry, postal services, and computer and telecommunications networks. This paper addresses two ... 
A Benders decomposition approach for the charging station location problem with plugin hybrid electric vehicles
(Elsevier, 2016)The flow refueling location problem (FRLP) locates p stations in order to maximize the flow volume that can be accommodated in a road network respecting the range limitations of the vehicles. This paper introduces the ... 
Benefits of forecasting and energy storage in isolated grids with large wind penetration – The case of Sao Vicente
(Elsevier, 2017)For electric grids that rely primarily on liquid fuel based power generation for energy provision, e.g. one or more diesel gensets, measures to allow a larger fraction of intermittent sources can payoff since the displaced ... 
The benefits of state aggregation with extremepoint weighting for assembletoorder systems
(Institute for Operations Research and the Management Sciences (INFORMS), 20180724)We provide a new method for solving a very general model of an assembletoorder system: multiple products, multiple components that may be demanded in different quantities by different products, batch production, random ... 
Benefits of transmission switching and energy storage in power systems with high renewable energy penetration
(Elsevier, 2018)Increasing the share of renewable energy sources in electricity generation helps address concerns about carbon emissions, global warming and energy security (i.e. dependence on fossil fuels). However, integrating intermittent ... 
The Best GainLoss Ratio is a Poor Performance Measure
(Society for Industrial and Applied Mathematics, 20130306)The gainloss ratio is known to enjoy very good properties from a normative point of view. As a confirmation, we show that the best market gainloss ratio in the presence of a random endowment is an acceptability index, ... 
Betti numbers for certain Cohen–Macaulay tangent cones
(Cambridge University Press, 2019)We compute Betti numbers for a Cohen–Macaulay tangent cone of a monomial curve in the affine 4space corresponding to a pseudosymmetric numerical semigroup. As a byproduct, we also show that for these semigroups, being ... 
Bicriteria multiresource generalized assignment problem
(John Wiley & Sons, 2014)In this study,we consider a bicriteria multiresource generalized assignment problem. Our criteria are the total assignment load and maximum assignment load over all agents. We aim to generate all nondominated objective ...
