The goal programming approach for the assembly area workload distribution problems
(Gazi Univ, Fac Engineering Architecture, 2009)In the real life, the systems generally have multiple and confliction aims. In the airplane industry, the elements of zero defect and punctual delivery are significant for security and prestige. However, it is obvious that ... -
The tricriteria flowshop scheduling problem
(Springer London Ltd, 2008)Multicriteria flowshop scheduling problems have been one of the most attractive subjects in recent years. In the multicriteria flowshop scheduling literature, a very limited number of studies have been performed on problems ... -
Minimizing the maximum lateness in a scheduling problem with a time-dependent learning effect: A non-linear programming model
(Gazi Univ, Fac Engineering Architecture, 2008)In traditional scheduling problems, most literature assumes that the processing time of a job is fixed. However, there are many situations where the processing time of a job depends on the starting time or the position of ... -
Comparing efficiencies of genetic crossover operators for one machine total weighted tardiness problem
(Elsevier Science Inc, 2008)In this study, the well-known one machine problem with the performance criterion of minimizing total weighted tardiness is considered. This problem is known to be NP-hard, and consists of one machine and n independent jobs. ... -
Optimal buffer allocation in finite closed networks with multiple servers
(Pergamon-Elsevier Science Ltd, 2008)In this study, we present an optimal buffer allocation procedure for closed queueing networks with finite buffers. The performance measures are evaluated using the expanded mean value analysis, and the solution procedure ... -
A bicriteria flowshop scheduling with a learning effect
(Elsevier Science Inc, 2008)In many situations, a worker's ability improves as a result of repeating the same or similar tasks; this phenomenon is known as the learning effect. In this paper the learning effect is considered in a two-machine flowshop. ... -
Modeling and analyzing customer data in customer relationship management with artificial neural networks
(Gazi Univ, Fac Engineering Architecture, 2008)Customers must keep customer satisfaction as a top priority in order to keep up with increasing competition. In order to achieve, they need to be able to analyze their customers properly and pay attention to their individual ... -
Design optimization of cutting parameters when turning hardened AISI 4140 steel (63 HRC) with Al2O3+TiCN mixed ceramic tool
(Elsevier Sci Ltd, 2007)Due to their high hardness and wear resistance, Al2O3-based ceramics are one of the most suitable cutting tool materials for machining hardened steels. However, their high degree of brittleness usually leads to inconsistent ... -
A multicriteria flowshop scheduling problem with setup times
(Elsevier Science Sa, 2007)Most of research in production scheduling is concerned with the minimization of a single criterion. However, scheduling problems often involve more than one aspect and therefore require multicriteria analysis. In this ... -
Minimizing total tardiness in a scheduling problem with a learning effect
(Elsevier Science Inc, 2007)Minimizing of total tardiness is one of the most studied topics on single machine problems. Researchers develop a number of optimizing and heuristic methods to solve this NP-hard problem. In this paper, the problem of ... -
A customer threshold property for closed finite queueing networks
(Elsevier Science Bv, 2006)We present a new class of finite queues in cyclic networks with production blocking. We show that with a threshold property related to the number of customers in the network, these queues are insensitive to the allocation ... -
A bicriteria scheduling with sequence-dependent setup times
(Elsevier Science Inc, 2006)In this paper a bicriteria scheduling problem with sequence-dependent setup times on a single machine is considered. The objective function of the problem is minimization of the weighted sum of total completion time and ... -
A computer simulation for estimating lower bound fracture strength of composites using Weibull distribution
(Elsevier Sci Ltd, 2004)Estimating confidence lower bound for fracture strength of composites is a key concern in design and manufacture, and the Weibull distribution has been widely used for this purpose. Previous simulation-based studies presented ... -
Activity-based cost estimation in a push/pull advanced manufacturing system
(Elsevier Science Bv, 2004)The objective of this paper is to estimate the manufacturing and product costs by using activity-based costing (ABC) method in an advanced manufacturing system that is run under either material requirements planning (MRP) ... -
Effects of NaOCl on bond strengths of resin cements to root canal dentin
(Lippincott Williams & Wilkins, 2003)Microleakage occurs due to the lack of sealing ability of root sealing materials or adhesive cements used to lute post-core materials. This may cause premature failure of endodontic treatment. The purpose of this study was ... -
Light and heavy water cooled hybrid reactors for rejuvenation of LWR spent fuels
(Pergamon-Elsevier Science Ltd, 2003)This study analyzes the rejuvenation performance and energy production of D-T driven hybrid blankets fueled by LWR spent fuel and cooled by heavy water (D2O) and light water (H2O). A fuel zone is placed between two cylindrical ... -
Recycling of cutting tools in flexible manufacturing systems
(Taylor & Francis Ltd, 2003)Flexible manufacturing systems (FMS) are complex, with a high variety of entities. In particular, tool management is critically important for timely manufacture. Since a large number of tools flow in a medium-size FMS, it ... -
Analysis of the rejuvenation performance of hybrid blankets by using uranium fuels (UN, UC, UO2, U3Si2) and different coolants for various volume fraction
(Pergamon-Elsevier Science Ltd, 2000)The possibility of nuclear fuel rejuvenation in fusion reactors is investigated for different fuels and coolants. Neutronic performances of the deuterium-tritium (D-T) driven hybrid blankets, fuelled with UN, UC, UO2 and ... -
A fuzzy colour quantizer for renderers
(Elsevier Science Bv, 1998)This paper presents a new colour quantization method for ray tracing. Normally, quantization is carried out by generating statistics about the colours present in the original image. Then a colour look-up table is created ...
