Analysis of Markov multiserver retrial queues with negative arrivals
(Springer, 2001)Negative arrivals are used as a control mechanism in many telecommunication and computer networks. In the paper we analyze multiserver retrial queues; i.e., any customer finding all servers busy upon arrival must leave the ... 
Analysis of order review/release problems in production systems
(Elsevier Science B.V., Amsterdam, Netherlands, 1999)Order Review/Release (ORR) activities have mostly been ignored in past job shop research. In most previous studies, arriving jobs are immediately released to the shop floor without considering any information about the ... 
Analysis of reactive scheduling problems in a job shop environment
(Elsevier, 2000)In this paper, we study the reactive scheduling problems in a stochastic manufacturing environment. Specifically, we test the several scheduling policies under machine breakdowns in a classical job shop system. In addition, ... 
Analysis of serial production lines: Characterisation study and a new heuristic procedure for optimal buffer allocation
(Taylor & Francis, 2006)Buffer allocation in serial production lines is one of the important design issues, and hence it has been studied extensively in the literature. In this paper, we analyse the problem to characterise the optimal buffer ... 
Analysis of simple inventory control systems with execution errors: Economic impact under correction opportunities
(Elsevier, 201006)Motivated by recent empirical evidence, we study the economic impact of inventory record inaccuracies that arise due to execution errors. We model a set of probable events regarding the erroneous registering of sales at ... 
Analysis of the (Q, r) inventory model for perishables with positive lead times and lost sales
(Institute for Operations Research and the Management Sciences (INFORMS), 2008)We consider a perishable inventory system with Poisson demands, fixed shelf lives, constant lead times, and lost sales in the presence of nonnegligible fixed ordering costs. The inventory control policy employed is the ... 
Analysis of the (s, S) policy for perishables with a random shelf life
(Taylor & Francis, 2008)A continuous review perishable inventory system operating under the (s,S) policy is considered. Assuming a random shelf life with a general distribution, renewal arrivals and a negligible replenishment lead time, exact ... 
Analysis of the Behavior of Transient Period in NonTerminating Simulations
(Elsevier, 20060816)Computer simulation is a widely used tool for analyzing many industrial and service systems. However, a major disadvantage of simulation is that the results are only estimates of the performance measures of interest, hence ... 
Analysis of the in vitro nanoparticle–cell interactions via a smoothingsplines mixedeffects model
(Taylor and Francis, 2016)A mixedeffects statistical model has been developed to understand the nanoparticle (NP)–cell interactions and predict the rate of cellular uptake of NPs. NP–cell interactions are crucial for targeted drug delivery systems, ... 
Analytical loading models in flexible manufacturing systems
(Elsevier, 1993)It would be difficult to efficiently implement a manufacturing system without solving its design and operational problems. Based on this framework, a system configuration and tooling problem is modeled. The model turns out ... 
Ant colony optimization for the single model Utype assembly line balancing problem
(Elsevier, 2009)An assembly line is a production line in which units move continuously through a sequence of stations. The assembly line balancing problem is defined as the allocation of tasks to an ordered sequence of stations subject ... 
An anticipative scheduling approach with controllable processing times
(Elsevier, 2010)In practice, machine schedules are usually subject to disruptions which have to be repaired by reactive scheduling decisions. The most popular predictive approach in project management and machine scheduling literature is ... 
An application of an optimal behaviour of the greedy solution in number theory
(Akademiai Kiado Rt., 1993)Let a1, a2, ..., an be relative prime positive integers. The Frobenius problem is to determine the greatest integer not belonging to the set {Σj=1 najxj :x∈Z+ n}. The Frobenius problem belongs to the combinatorial number ... 
Applied Materials uses operations research to design its service and parts network
(Institute for Operations Research and the Management Sciences (INFORMS), 2010)Applied Materials Inc. is the global leader in nanomanufacturing technology solutions. It has a broad portfolio of innovative equipment, service, and software products and supports its customers worldwide with an extensive ... 
Approaches for inequityaverse sorting
(Elsevier, 2016)In this paper we consider multicriteria sorting problems where the decision maker (DM) has equity concerns. In such problems each alternative represents an allocation of an outcome (e.g. income, service level, health ... 
An approximate analytical method of analysis of a threshold maintenance policy for a multiphase multicomponent model
(Springer, 2003)A multicomponent system is investigated that consists of n identical unreliable components whose nonfailure operating time consists of a number of sequential phases with exponential times. A maintenance policy is studied ... 
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 ... 
Arçelik yurt içi tedarik zinciri için araç sevkiyat ve rotalama sistemi
(Makina Mühendisleri Odası, 2009)Bu çalışmada tedarikçilerden gelen malzemelerin Arçelik Bulaşık Makinesi İşletmesi’ne taşınması için kullanılacak rotaların ve taşıyıcıların hareket çizelgelerinin optimal veya optimale yakın bulunması amacıyla bir karar ... 
Artificial neural network modeling and simulation of invitro nanoparticlecell interactions
(American Scientific Publishers, 2014)In this research a prediction model for the cellular uptake efficiency of nanoparticles (NPs), which is the rate that NPs adhere to a cell surface or enter a cell, is investigated via an artificial neural network (ANN) ... 
Ascending Combinatorial Auctions with Risk Averse Bidders
(Springer, 2016)Ascending combinatorial auctions are being used in an increasing number of spectrum sales worldwide, as well as in other multiitem markets in procurement and logistics. Much research has focused on pricing and payment ...
