Fuzzy multi-objective programming algorithm for vehicle routing problems with backhauls
(Pergamon-Elsevier Science LTD, 2015)The vehicle routing problem with backhauls (VRPB) is an extension of the standard vehicle routing problem. VRPB has two sets of customers: linehaul customers and backhaul customers. The aim of this study is to propose a ... -
Fuzzy rule-based (p)over-tilde and n(p)over-tilde control charts
(Ios Press, 2014)In a process using monitoring with p-control charts or np-control charts, due to the uncertainty of the attribute data, traditional control charts may be insufficient. In this case, fuzzy control charts are pertinent control ... -
A generalization of a theorem of Arrow, Barankin and Blackwell to a nonconvex case
(Taylor & Francis LTD, 2016)The paper presents a generalization of a known density theorem of Arrow, Barankin, and Blackwell for properly efficient points defined as support points of sets with respect to monotonically increasing sublinear functions. ... -
Hartley properly and super nondominated solutions in vector optimization with a variable ordering structure
(Springer, 2018)In this paper, we introduce Hartley properly and super nondominated solutions in vector optimization with a variable ordering structure. We prove the connections between Benson properly nondominated, Hartley properly ... -
Hata Türü ve Etkileri Analizi ve Kalite Fonksiyon Yayılımı İle Bir İnşaat Firması İçin Risk Değerlendirmesi
(2017)Risk kavramı, 1920'li yıllardaki ekonomik ve teknolojik gelişmeler ile daha önemli hale gelmiştir. Risklerin sistemli bir şekilde kontrolü, iyi bir risk yönetimi ile mümkün olabilir. Risk değerlendirmesi, risk yönetiminin ... -
Heuristic algorithms for the single allocation <bold>p</bold>-hub center problem with routing considerations
(Springer, 2019)Given a network with n nodes, the p-hub center problem locates p hubs and allocates the remaining non-hub nodes to the hubs in such a way that the maximum distance (or time) between all pairs of nodes is minimized. Commonly, ... -
Hybrid approach for Pareto front expansion in heuristics
(Palgrave Macmillan LTD, 2011)Heuristic search can be an effective multi-objective optimization tool; however, the required frequent function evaluations can exhaust computational sources. This paper explores using a hybrid approach with statistical ... -
A Hybrid Genetic Algorithm For the Quadratic Assignment Problem on Graphics Processing Units
(2016)Bu çalışmada karesel atama probleminin çözümü için melez bir genetik algoritma önerilmiştir. Önerilen algoritmanın en zaman alıcı bölümleri amaç fonksiyonun hesaplanması ve yerel arama operatörüdür. Bu nedenle algoritmanın ... -
An incremental clustering algorithm based on hyperbolic smoothing
(Springer, 2015)Clustering is an important problem in data mining. It can be formulated as a nonsmooth, nonconvex optimization problem. For the most global optimization techniques this problem is challenging even in medium size data sets. ... -
An incremental piecewise linear classifier based on polyhedral conic separation
(Springer, 2015)In this paper, a piecewise linear classifier based on polyhedral conic separation is developed. This classifier builds nonlinear boundaries between classes using polyhedral conic functions. Since the number of polyhedral ... -
Inventory control and pricing for perishable products under age and price dependent stochastic demand
(Springer Heidelberg, 2018)Perishable products have a short lifetime and cause a high amount of wastage when managed ineffectively, due to their deterioration over time. We consider coordinated inventory and pricing decisions for perishable products ... -
İş Kazası Verilerinin Olasılık Dağılımları İle Modellenmesi
(2017)Dünya'da her yıl milyonlarca insan iş kazaları nedeniyle yaralanmakta, yaşamını yitirmekte ya da işle ilgili meslek hastalığına yakalanmaktadır. İş kazalarının, meslek hastalıklarının ve olay sonucu ortaya çıkan maliyetlerin ... -
Karma Modelli Montaj Hatlarında Üretim Çizelgeleme ve Sıralama Problemlerinde Üretim Düzgünleştirme İçin Bir Yaklaşım Önerisi
(2015)Karma model montaj hatları, aynı anda iki ya da daha fazla ürün tipinin aynı hat üzerinde üretilebildiği, çeşitlendirilmiş küçük parti üretimine yatkın ve modellerin çeşitliliğine rağmen fazla stok bulundurmadan, ani talep ... -
Kurum imajı analizi: Bir üretim işletmesi örneği
(2012)Özellikle Endüstri Devriminden sonra rekabetçi pazarda öne çıkma çabalarına paralel olarak meydana gelmiş olan imaj kavramı, günümüzde salt görsellikten ibaret bir kavram olmaktan çıkmıştır. Güvenilirlik, kalite, istikrarlılık ... -
Kısa Ömürlü Ürünler İçin Koordineli Bir Stok ve Fiyat Yönetimi Modeli
