Simulation analysis of the blood supply chain and a case study

Yegül, Mert
Efficient management of blood throughout the countries is of great economic importance, in addition to its major impact on the success of medical operations. This study is concerned with the analysis of policies for managing a unique blood supply chain network, which is defined in the new Blood and Blood Products Law of the Republic of Turkey. The main objective of the study is to obtain a better understanding of the system, and to find improved policies to be able to manage it efficiently. A discrete event simulation model is developed to analyze the blood supply chain of a pilot region in Turkey. Effects of different management policies on the supply chain performance are analyzed. Important improvements are achieved in terms of the selected performance measures such as outdate, mismatch and shortage rates of the region. Our proposed model can be used by both national health authorities and the Turkish Red Crescent Society as a decision support tool to analyze other regions and to examine alternative policies.


Optimal air defense strategies for naval task group
Karasakal, Orhan; Özdemirel, Nur Evin; Department of Industrial Engineering (2004)
We develop solution methods for the air defense problem of a naval task group in this dissertation. We consider two interdependent problems. The first problem is the optimal allocation of a set of defensive missile systems of a naval task group to a set of attacking air targets. We call this problem the Missile Allocation Problem (MAP). The second problem called the Sector Allocation Problem (SAP) is the determination of a robust air defense formation for a naval task group by locating ships in predefined s...
An analysis of the prevalence of malaria in Turkey over the last 85 years
Piyal, Birgul; Akdur, Recep; Ocaktan, Esin; Yozgatlıgil, Ceylan (Informa UK Limited, 2013-01-01)
Background: Affecting 106 countries, malaria is a major global burden. Though intensive antimalaria efforts in Turkey have been successful in bringing down the number of cases, historically malaria was a serious public health concern.
CMOS Cell Sensors for Point-of-Care Diagnostics
Adiguzel, Yekbun; Külah, Haluk (2012-08-01)
The burden of health-care related services in a global era with continuously increasing population and inefficient dissipation of the resources requires effective solutions. From this perspective, point-of-care diagnostics is a demanded field in clinics. It is also necessary both for prompt diagnosis and for providing health services evenly throughout the population, including the rural districts. The requirements can only be fulfilled by technologies whose productivity has already been proven, such as comp...
Improvement Of Service Quality By Using Ubiquitous Computing In Hospitality
Gökalp, Ebru; Eren, Pekin Erhan (null; 2014-12-10)
Economies of developed countries are primarily based on the services sector, where the hospitality industry plays an important role. As such, new service design and service innovation are vital for maintaining competitive advantage. Recently, ubiquitous computing has emerged as a key enabler in various industries in support of service innovation by facilitating the design of new services. This study aims to investigate the benefits provided by ubiquitous computing in the hospitality domain for improved serv...
Analysis of economic data using robust methods
Coşar, Evren Erdogan; Akkaya, Ayşen; Department of Statistics (2002)
Export plays an important role in the economic development of a country. Because of its importance in implementing trade policies, there is an extensive literature on the estimation of export functions. Most of the studies on estimating export functions utilized conventional econometric techniques with the normality assumption of innovations. However, it has been recently recognized that non-normal distributions for innovations are more common in practice. IllThe main aim of this study is to estimate the ex...
