Solution approaches to the blood distribution problem of the Turkish Red Crescent

Kurt, Atil
Azizoğlu, Meral
This paper considers the blood distribution problem that includes irradiation centres, urgent demands, and product availability in Turkey, Central Anatolian Regional Blood Center of the Turkish Red Crescent. To address the problem, we develop a mixed integer linear program with two objectives: maximising the demand satisfaction and minimising total time travelled by the vehicles. We propose two decomposition-based heuristic solution approaches. The results of our experiments have revealed that the model cannot solve even small sized instances in reasonable times; however, the heuristic solution approaches are appropriate for solving complex real life problems.


A blood distribution problem with new transportation options - An application for the Turkish Red Crescent
Kurt, Atil; Çetinkaya, Ferda Can; Azizoğlu, Meral (Inderscience Publishers, 2019-01-01)
This paper considers the blood distribution problem in the Central Anatolian Regional Blood Centre of the Turkish Red Crescent (TRC) and proposes several demand satisfaction options considering the irradiation centres, urgent demands, and product availability. Our aim is to maximise the total weighted blood demand satisfaction. To address the problem, we develop a mixed integer linear programming model and propose a hybrid genetic algorithm (HGA). The results of our experiments have revealed that the mathem...
Application of strategic planning methodology to Republic of Turkey Ministry of Finance
Özahçı, Erhan; Şen, Tayyar; Department of Industrial Engineering (2007)
In this study, it is aimed to determine and implement a process based strategic planning methodology for Turkish Ministry of Finance. Proposed methodology has been implemented in Ministry of Finance by a TÜBİTAK supported strategic management project in collaboration with Ministry of Finance Strategy Development Unit (MoF_SDU), TÜSSİDE and a private Consultancy Company. This project was a direct consequence of reforms on Public Financial Management and stipulated by the Laws No. 5018 and 5436 which have bee...
Reaction chemistry of gold leaching in thiourea solution for a Turkish gold ore
Orgul, S; Atalay, U (Elsevier BV, 2002-12-01)
This study was carried out on a finely disseminated gold-bearing ore from Kaymaz, Turkey. The main objective was to determine the mechanism of reaction between thiourea and Fe 31 in the thiourea leaching of gold. Thiourea consumption levels were also examined during the leaching operations for different leaching parameters, i.e., molar ratio of ferric sulfate/thiourea, pH, and temperature. The leaching using the thiourea process was compared with cyanidation. In optimum leach conditions, 85.8% gold extracti...
An approximate model for base-stock-controlled assembly systems
Avşar, Zeynep Müge; RODOPLU, Umut (Informa UK Limited, 2009-03-01)
This study is on continuously reviewed base-stock-con trolled assembly systems with Poisson demand arrivals and exponential single-server facilities used for manufacturing and assembly operations. A partially aggregated but exact queueing model is developed and approximated assuming that the state-dependent transition rates arising as a result of the partial aggregation are constant. It is shown that the steady-state probability distribution of this approximate model is a product-form distribution for the s...
Optimisation of formulations and infrared-microwave combination baking conditions of chestnut-rice breads
Demirkesen, Ilkem; Şümnü, Servet Gülüm; Şahin, Serpil; Uysal, Nalan (Wiley, 2011-09-01)
The main objective of this study was to design gluten-free breads containing chestnut and rice flour and xanthan-guar gum blend to be baked in infrared-microwave combination oven. Response surface methodology (RSM) was used to optimise gluten-free bread formulations and processing conditions. Weight loss, firmness, specific volume and colour change of the breads were determined. Rice flour mixed with different proportions of chestnut flour and different emulsifier contents were used to prepare breads. The g...
