While the concept of regional organization (regionalization) of perinatal care aimed at reducing perinatal mortality has remained at the agenda of developed countries since 1970’s, Turkey is one of the countries that does not have such a system yet. In this study, a three-level hierarchical location-allocation model is developed for the regionalization of perinatal care in an attempt to have a better distribution of maternal and perinatal health care services in Turkey. Since the mathematical model developed is difficult to solve in a reasonable time, we propose three heuristic approaches: top-down, modified top-down and Lagrangean relaxation based heuristics. These heuristics are computationally tested on a set of problem instances for networks ranging from 10 to 737 vertices. A significant result is that Lagrangean relaxation based heuristic outperforms the other two heuristics in terms of solution quality. In most of the test problems, the modified top-down heuristic outperforms the top-down heuristic in terms of solution quality. Using the proposed approaches, we solve a real life problem corresponding to the Eastern and South Eastern Anatolian Regions (the East Region) of Turkey.

A genetic algorithm for maximum-weighted tree matching problem Gulek, Mehmet; Toroslu, İsmail Hakkı (Elsevier BV, 2010-09-01) In hierarchal organizations, for assigning tasks to the divisions of the organization some constraints must be satisfied. This article investigates one such problem in which there are k different tasks to be accomplished and each division's performance on each task may be different and represented by a scalar value. In this article we formally introduce this real life decision problem, named as Maximum-Weighted Tree Matching Problem, and propose a genetic algorithm solution to it, and give some experimental...
A decision support system for production planning and pre-cost estimation activities in an apparel company Gökalp, Ebru; Şen, Tayyar; Department of Industrial Engineering (2010) In this study, a specific decision support system is designed and developed for Production Planning and Marketing Department of an apparel company. The developed system involves two modules with user friendly interface or data input and query. The system is designed to provide support in the following fields of decision making; pre cost estimation, capacity planning, master production planning and production scheduling. A detailed analysis of the existing system is conducted and Microsoft Access is used for...
Analysis of a two-echelon multi-item inventory system with postponement Eryılmaz, Hande; Meral, Fatma Sedef; Department of Industrial Engineering (2010) Increased product proliferation and global competition are forcing companies within the supply chain to adopt new strategies. Postponement is an effective strategy that allows companies to be agile and cost effective in dealing with the dynamics of global supply chains. Postponement centres around delaying activities in the supply chain until real information about the market is available, which reduces the complexity and uncertainty of dealing with a proliferation of products. A two-echelon divergent suppl...
A Comparison of Process Ontology Discovery from Organizational Guidelines in Two Different Languages Gurbuz, Ozge; Demirörs, Onur (2017-09-01) Process ontologies contain organization's process elements which are related to the business activities, in a structured format. Once organizations establish process ontologies, searching process information as well as discovery, modeling and automation become more efficient. Process ontologies are frequently developed from organizational resources such as guidelines, regulations and procedures by interpreting the document, discovering the process information and building the ontology. The studies depict th...
A methodology for determining the cluster of a new project Yiğit, Aybeniz; Saatçioğlu, Ömer; Department of Industrial Engineering (2005) By definition, all projects are unique; however R&D projects have specific characteristics that make them harder to manage. The project management methodology applied to R&D projects may show differences due to the categorization of them. But if there exists a categorization of projects, one can analyze the properties of the project classes and then manage similar projects similarly. In this study, the R&D projects of a main military electronics company of Turkey, are analyzed. Tunç (2004) has developed a m...
