“…A survey is given by Campbell (1994b). The problem of locating such interacting hub facilities arises in many applications some of which include airlines, see Campbell (1992), Aykin (1995b), the Civil Aeronautics Board, see O'Kelly (1986O'Kelly ( , 1987, emergency services, see Campbell (1994a) and postal delivery services, see Ernst and Krishnamoorthy (1996).…”

The design of the distribution system is a Strategie issue for almost every Company. The Problem of locating facilities and allocating customers Covers the core topics of distribution system design. Model formulations and Solution algorithms which address the issue vary widely in terms of fundamental assumptions, mathematical complexity and computational Performance. This paper reviews some of the contributions to the current state-of-the-art. In particular, continuous location models, network location models, mixed-integer programming models, and applications are summarized. Terms of use: Documents in EconStor may

“…Daha sonra Campbell [7,8] ADÜ yer seçim problemleriyle ilgili benzer amaç fonksiyonlarına sahip birçok matematiksel model önermiştir. Ayrıca, Aykin [9][10][11][12] akışa dayalı atama yaklaşımı ile ve Klincewicz [13,14] hem akışa hem mesafeye bağlı atama prosedürü ile alanın genişlemesinde kritik rol oynamışlardır.…”

ÖZETAna dağıtım üsleri (ADÜ) çoktan-çoğa dağıtım sistemlerinde toplama, sınıflandırma ve aktarma noktası olarak hizmet veren özel tesislerdir. ADÜ yer seçim problemlerinde, kaynak-varış noktaları arasındaki akışlar doğrudan birbirleri arasında değil, ölçek ekonomisinden faydalanmak amacıyla ana dağıtım üsleri aracılığıyla gerçekleştirilir. Bu sayede daha az bağlantı hattı ve daha düşük maliyetlerle daha fazla noktaya bağlantı sağlanmış olur. Bu çalışmada, bir kamu kurumuna yönelik gerçek bir ana dağıtım üssü yer seçim problemi ele alınmıştır. Kurumun talepleri ve problemin gereksinimlerinden yola çıkılarak, literatürde yer alan kapasite kısıtlı ve çok atamalı yapıya sahip ADÜ yer seçim problemlerine yeni boyut kazandırılmıştır. Literatürde yer alan çalışmalardan farklı olarak, ADÜ olarak seçilmeyen kaynak-varış çiftleri arasındaki akışlarda ADÜ kullanma zorunluluğu gevşetilmiş ve ADÜ olarak seçilen düğümlerin kapasitelerinin hem ADÜ, hem de ADÜ olarak seçilmeyen düğümlerden gelen akışlardan etkilenmesi sağlanmıştır.Anahtar Sözcükler: Tesis yeri seçimi, ana dağıtım üssü yer seçimi, matematiksel modelleme CAPACITATED MULTIPLE ALLOCATION HUB LOCATION PROBLEM WHICH ALLOWS DIRECT FLOW BETWEEN NODES ABSTRACTHubs are special facilities that serve as switching, transshipment and sorting points in many-to-many distribution systems. In hub location problems, transfers between origin-destination points do not take place directly between each other, but by means of hubs for the purpose of taking advantages of economies of scale. Thus, it becomes possible to provide connections to more points with less lines and costs. In this study, a real hub location problem is studied for a public institution. On the basis of the institutions' demands and the problems' requirements, a new dimension has been provided to the capacitated multiple allocation hub location problems which have significance in the literature. Unlike the studies conducted in the literature, obligation to use hubs among the origin-destination pairs that are unselected hub is relaxed and the capacities of nodes that are selected as hubs are provided to be affected by the flows both from the hubs and the spokes.

“…To introduce a more comprehensive framework with networking policies, Aykin [11] developed several integer programming models considering different networking policies. Each of his models deals with a special case in which a specified networking policy is applied.…”
