A tabusearch based heuristic for the hub covering problem over incomplete hub networks
(Elsevier, 2009)Hub location problems deal with finding the location of hub facilities and with the allocation of demand nodes to these located hub facilities. In this paper, we study the single allocation hub covering problem over ... 
Tactical capacity management under capacity flexibility
(Institute of Industrial Engineers, 2008)In many production systems a certain level of flexibility in the production capacity is either inherent or can be acquired. In that case, system costs may be decreased by managing the capacity and inventory in a joint ... 
Technical notea conic integer optimization approach to the constrained assortment problem under the mixed multinomial logit model
(INFORMS The Institute for Operations Research and the Management Sciences, 2018)We consider the constrained assortment optimization problem under the mixed multinomial logit model. Even moderately sized instances of this problem are challenging to solve directly using standard mixedinteger linear ... 
Technical noteoptimal structural results for assembletoorder generalized MSystems
(INFORMS Inst.for Operations Res.and the Management Sciences, 2014)We consider an assembletoorder generalized Msystem with multiple components and multiple products, batch ordering of components, random lead times, and lost sales. We model the system as an infinitehorizon Markov ... 
Temperature dependent flow softening of titanium alloy Ti6Al4V: An investigation using finite element simulation of machining
(Elsevier, 2011)Titanium alloy Ti6Al4V is the most commonly used titanium alloy in the aerospace and medical device industries due to its superior properties. There has been a considerable amount of research to better understand the ... 
Tepe Mobilya' da hücresel üretimle teslimat sürelerinin kısaltılması
(TMMOB, 2006)Tepe Mobilya Fabrikası'nda döşemeli ürünlerin teslimat sürelerinin azaltılması fabrika ve ürünlerin satışlarını gerçekleştiren Tepe Home için büyük önem taşımaktadır. Bu projede fabrikanın hücresel üretime geçişi için bir ... 
A thermomechanical model of drill marginborehole surface interface contact conditions in dry drilling of thick CFRP laminates
(Elsevier, 2020)Dry drilling of thick carbon fiber reinforced polymer (CFRP) laminates requires careful selection of process parameters in order to obtain acceptable borehole surface quality. Complex contact conditions between the drill ... 
Time constrained maximal covering salesman problem with weighted demands and partial coverage
(Elsevier Ltd, 2016)In a routing framework, it may not be viable to visit every single customer separately due to resource limitations or efficiency concerns. In such cases, utilizing the notion of coverage; i.e., satisfying the demand of ... 
Tool allocation and machining conditions optimization for CNC machines
(Elsevier, 1996)In the literature, there exist many variations of machining economics problem in terms of modelling approaches and solution methodologies. However most of the existing studies focus on the single machining operation which ... 
Tool geometry based prediction of critical thrust force while drilling carbon fiber reinforced polymers
(Shanghai University Press, 2015)Carbon fiber reinforced polymers (CFRPs) are known to be difficult to cut due to the abrasive nature of carbon fibers and the low thermal conductivity of the polymer matrix. Polycrystalline diamond (PCD) drills are commonly ... 
Tool magazine arrangement and operations sequencing on CNC machines
(Elsevier, 199602)twophase approach is developed to solve the tool magazine arrangement and operations sequencing problems. The overall aim is to minimize the total manufacturing cost by utilizing the benefits of tool sharing concept and ... 
Toz deterjan için üretim planlama ve çizelgeleme sistemi tasarımı
(TMMOB Makina Mühendisleri Odası, 2009)Unilever Gebze Fabrikasının toz deterjan üretimi planlama sürecinde çizelgeleme işlemi için karar destek sisteminin eksikliği, ürün değişikliklerinin neden olduğu kurulum sayısının ve fırsat maliyetlerinin artmasına sebep ... 
Tractability of convex vector optimization problems in the sense of polyhedral approximations
(Springer New York LLC, 2018)There are different solution concepts for convex vector optimization problems (CVOPs) and a recent one, which is motivated from a set optimization point of view, consists of finitely many efficient solutions that generate ... 
Training an artificial neural network the pure pursuit maneuver
(Pergamon Press, 1991)Artificial neural networks' ability to learn, categorize, generalize and self organize make them potentially very useful for a variety of application areas. This paper discusses some experiences in attempting to teach a ... 
Transportation pricing of a truckload carrier
(Elsevier, 2011)Freight transportation is a major component of logistical operations. Due to the increase in global trade, fierce competition among shippers and raising concerns about energy, companies are putting more emphasis on effective ... 
A transportation type aggregate production model with bounds on inventory and backordering
(Elsevier, 1988)We consider a certain T period aggregate production planning model, where the two sources of production are regular and overtime. The model allows for time varying production, holding and backordering costs and includes ... 
Tree network 1median location with interval data: a parameter spacebased approach
(Taylor & Francis, 2005)We consider a family of 1median location problems on a tree network where the vertex weights are ranges rather than point values. We define a new framework for making sound decisions under uncertainty which is primarily ... 
The Turkish army uses simulation to model and optimize its fuelsupply system
(Institute for Operations Research and the Management Sciences (INFORMS), 2005)Moving military troops, which is critical to tactical success, depends on providing large quantities of fuel. We used simulation to model and analyze the Turkish army's fuelsupply system that consists of seagoing tankers, ...
