A Bi-Objective Integrated Mathematical Model For Blood Supply Chain: Case Of Turkish Red Crescent

Satır, Benhür; Yolcu, Vahdi (2023-05)

Various criteria feature in blood supply chain (BSC) designs, where cost-based and time-based are the most commonly found in the literature. In the current study, total annual cost is used together with a new time-based ...
A branch and bound algorithm for sector allocation of a naval task group

Karasakal, Orhan; Kandiller, Levent; Özdemirel, Nur Evin (Wiley-Blackwell, 2011-10)

A naval task group (TG) is a collection of naval combatants and auxiliaries that are grouped together for the accomplishment of one or more missions. Ships forming a TG are located in predefined sectors. We define determination ...
A decision support system for locating weapon and radar positions in stationary point air defence

Tanergüçlü, Türker; Maras, Hakan; Gencer, Cevriye; Aygüneş, Haluk (Springer, 2012-04)

In this study, a decision support system (DSS) based on the interactive use of location models and geographical information systems (GIS) was developed to determine the optimal positions for air defence weapons and radars. ...
A General Production and Financial Planning Model: Case of A Poultry Integration

Satır, Benhür; Yıldırım, Gonca (Springer, 2020)

We propose a general linear programming formulation for a poultry integration to facilitate decision making in production and financial planning. The formulation is motivated by a medium-size application and by involving ...
A multi-objective approach for dynamic missile allocation using artificial neural networks for time sensitive decisions

Karasakal, Orhan; Karasakal, Esra; Silav, Ahmet (2021-08)

In this study, we develop a new solution approach for the dynamic missile allocation problem of a naval task group (TG). The approach considers the rescheduling of the surface-to-air missiles (SAMs), where a set of them ...
A Multiple Criteria Ranking Method Based on Outranking Relations: An Extension for Prospect Theory

Karasakal, Esra; Karasakal, Orhan; Hazel, Şentürk (2022)

In this study, Prospect Theory is integrated into a well-known multiple criteria ranking method, PROMETHEE. PROMETHEE considers the outranking relations among alternatives based on the preference functions. Prospect Theory ...
A Paradox of the Average Waiting Time for the Case of a Single Bottleneck on the Commuters' Route

Özaktaş, Hakan; Kırkavak, Nureddin; Alpay, Ayşe Nilay (2021-05-24)

Average waiting time is considered as one of the basic performance indicators for a bottleneck zone on a route for commuter traffic. It turns out that the average waiting time in a queue remains paradoxically unchanged ...
A partial coverage hierarchical location allocation model for health services

Karasakal, Orhan; Karasakal, Esra; Töreyen, Özgün (2023)

We consider a hierarchical maximal covering location problem (HMCLP) to locate health centres and hospitals so that the maximum demand is covered by two levels of services in a successively inclusive hierarchy. We extend ...
A Petri Net-based inference network for design automation under nondeterminism applied to mechatronic systems

Erden, Z.; Erkemn, A. M.; Erden, A. (1998)

This paper introduces the completed part of an ongoing research, in which a Petri Net-based design inference network is developed for the representation and analysis of the functions and their interrelationships through ...
A Procurement Auctions-Based Framework for Coordinating Platforms in Humanitarian Logistics

Ertem, Mustafa Alp; Buyurgan, Nebil (2013)

This chapter focuses on an auction-based procurement framework for single coordinating platforms in humanitarian logistics. It first covers disaster relief operations, humanitarian logistics, and procurement in this context ...
A Sociocultural Landmark in Ankara: 96lar Residential Block

Ürey Uysal, Zeynep Çiğdem (2012)

Bu çalışma, Ankaranın önemli bir kentsel simgesi olan 96lar Apartmanını, gelişiminin sosyokültürel önemi bağlamında incelemeyi amaçlamaktadır. Araştırmaların da işaret ettiği gibi 96lar Apartmanı, Ankarada 1950li ve ...
A study on nutrient removal from municipal wastewater by struvite formation using Taguchi's design of experiments

Uludağ Demirer, Sibel (Mary Ann Liebert Inc, 2008-02)

The aim of this study is to investigate the removal of NH4+-N and PO43--P from the municipal wastewater by struvite (MgNH4PO4.6H(2)O) formation. The optimization of the NH4+-N and PO43--P removals is made by changing the ...
A Systems Approach for Technology Assessment and Selection

Demirkiran, Zuhal Kale; Altunok, Taner (2012)

Each system development project necessitates making decisions on the selection of technologies among available alternatives for the system and is covered in the technology assessment phase in the acquisition process. For ...
A technology readiness levels (TRLs) calculator software for systems engineering and technology management tool

Altunok, Taner; Çakmak, Tanyel (Elsevier Science Ltd, 2010-05)

Turkish defense industry and policy makers seek effective and successful system development programs by implementing a validation mechanism to verify the maturity of new technologies being developed in national laboratories ...
A truck loading problem

Yüceer, Ümit; Özakça, Arif (Pergamon-Elsevier Science Ltd, 2010-05)

A vehicle with m compartments transports q different products of various sizes from a source to n different destinations. The operational problem is how to load the compartments of the vehicle so that the replenishment ...
Ağların hareketli yol-kesici tarafından en kısa güzergâh kullanılarak kesilmesi

Kabarcık, Ahmet; Kandiller, Levent; Aygüneş, Haluk (2012)

Bu makalede yolların hareketli yol-kesici tarafından devre dışı bırakıldığı bir ağ kesme problemi ele alınmıştır. İçiçe geçmiş iki ağdan biri ağ-kullanıcı tarafından, diğeri ise yol-kesici tarafından kullanılmaktadır. ...
Ammonia removal from anaerobically digested dairy manure by struvite precipitation

Uludağ Demirer, Sibel; Demirer, G. N.; Chen, S. (Elsevier Science LTD, 2005-12)

Ammonia is one of the most important contaminants impairing the quality of water resources. When this is considered along with the fact that the global demand for nitrogenous fertilizers is in constant rise, the need for ...
An approach for extending PROMETHEE to reflect choice behaviour of the decision maker

Karasakal, Esra; Karasakal, Orhan; Bozkurt, Ahmet (2019)

In this study, an approach based on PROMETHEE is developed to correctly reflect the choice behavior of the decision maker that is not explained by the utility theory. The prospect theory argues that losses have higher ...
An approach to discrete convexity and its use in an optimal fleet mix problem

Cambini, Riccardo; Riccardi, Rossana; Yüceer, Ümit (Springer-Verlag Berlin, 2006)

A notion of convexity for discrete functions is first introduced, with the aim to guarantee both the increasing monotonicity of marginal increments and the convexity of the sum of convex functions. Global optimality of ...
An approximation for kanban controlled assembly systems

Topan, Engin; Avşar, Zeynep Müge (Springer, 2011-01)

An approximation is proposed to evaluate the steady-state performance of kanban controlled two-stage assembly systems. The development of the approximation is as follows. The considered continuous-time Markov chain is ...
