Article Citation Count: 32Determination of key performance indicators for measuring airport success: A case study in Libya(Elsevier Ltd, 2018) Erkan, Turan Erman; Badi,I.; Abdulshahed,A.; Erkan,T.E.; Industrial EngineeringAirports need to evaluate their performance and effectiveness periodically to determine whether objectives are being achieved and how their performance compares to similar best practices. The goals of this paper are twofold: First, to offer a list of essential airport key performance indicators (KPIs) that can provide decision makers in the Libyan airport industry a practical framework to measure and monitor performance over time. The second goal is to use the AHP technique to derive the weights of the KPIs and to select the best international airport in Libya based on the values of the KPIs at each airport according to the judgments of experts. However, the implementation steps of the AHP method will be simplified by using the Expert Choice software. The paper presents the importance weights of seventeen KPIs across five aspects of airport performance. As a result of this study, Libyan airports can benchmark their performance against others or through internal benchmarking. © 2017 Elsevier LtdConference Object Citation Count: 0Layout improvement method selection for a mass production facility(IEOM Society, 2018) Baç, Uğur; Erkan, Turan Erman; Industrial EngineeringPurpose of this study is to identify, analyze, and propose a solution to an industrial problem that would satisfy the needs of a manufacturing company by using tools and techniques of Industrial Engineering. For this purpose, production system of a metal cap manufacturer company, which is a well-known mass production company in packaging industry since 1963 in Turkey, has been inspected. In the first part of the study, overall system has been analyzed, problem symptoms have been identified, and then the problem definition has been made. Two problems have been defined as: (i) insufficient production capacity, and (ii) inefficient production system. According to these findings, objectives of this study has been determined as: (i) the improvement of the efficiency of current system by making some layout changes and making small-scale investments, (ii) analyze large-scale investment alternatives in the long run and conduct engineering economic analysis of these investment alternatives. Within this scope, alternative solution approaches, analysis of these alternatives, and selection of best alternative have been accomplished. As a result of this study capacity of the facility can be increased by 16% and investment required for this increase has a payback period of 71 days. © IEOM Society International.Article Citation Count: 16Sector selection for ERP implementation to achieve most impact on supply chain performance by using AHP–TOPSIS hybrid method;(Strojarski Facultet, 2014) Baç, Uğur; Erkan, Turan Erman; Erkan,T.E.; Industrial EngineeringRecently, studies about the Enterprise Resource Planning (ERP) have been increased and this research area has attracted more attention. Especially, in the global competition environment, enterprises have to focus on their Information Systems (IS) performance to have a competitive advantage; implementing an ERP system and improving the effectiveness of the system is the only way. However every sector reacts to ERP implementation differently. Purpose of this study is to rank the sectors according to their performance increments after successful ERP implementations by using AHP-TOPSIS hybrid method. As a result, general structure of Turkish companies will be pictured and the sectors which have the most chance to improve their performance by utilizing an ERP system will be defined. These findings will help the companies to plan the implementation process more precisely and help the managers of these companies to define their expectations more clearly. A numerical example is given to clarify the main developed result in this paper. © 2014, Technical Gazette.

In this study AHP (Analytic Hierarchy Process) and FAHP (Fuzzy Analytic Hierarchy Process) are used to choose between Barcode and RFID systems for the company warehouse data collection system. This decision is affected by four criteria which are: cost, functionality, sustainability and performance. The barcode system was preferred by 68 % and RFID was preferred by 32 % according to AHP. For FAHP, barcode system was preferred by 72 % and RFID was preferred by 28 %. Consequently AHP values are consistent with FAHP values. Finally barcode system is selected for the company's warehouse data collection system and FAHP is found to be relatively more sufficient in terms of description of this decision-making process because of its fuzziness and vagueness compared to AHP method.Article Citation Count: 65Selection of academic staff using the fuzzy Analytic Hierarchy Process (FAHP): A pilot study;(2012) Erkan, Turan Erman; Erkan,T.E.; Industrial EngineeringEvaluating candidates' suitability for a selection of academic staff is an important tool for Human Resources Management (HRM) to select the most suitable candidates for required posts. There are various methods regarding the selection of staff in the field. As there are increasing improvements in the field of education, universities around the world demand high quality and professional academic staffs. The present paper examines a fuzzy Analytic Hierarchy Process (FAHP) for selecting the most suitable academic staff, where five candidates under ten different sub-criteria are evaluated and prioritised. The FAHP method adopted here uses Triangular Fuzzy Numbers (TFN). The inability of AHP to deal with the impression and subjectiveness in the pair-wise comparison process has been improved in the FAHP. Instead of a crisp value, the FAHP generates a range of values to incorporate the decision-makers uncertainty. Also, a real case study is presented.Article Citation Count: 0Solving a mixed purchasing process problem in retail market: A pilot study in Turkey;(Strojarski Facultet, 2014) Erkan, Turan Erman; Rouyendegh,B.D.; Salar,M.; Industrial EngineeringThe details of mixed purchasing processes which consist of some of sales and marketing processes in a retail market are discussed in this pilot study. The purpose of this pilot study is to analyse purchasing AS-IS processes, to make benchmarking to the competitors for doing comparison, to determine criteria for alternative purchasing AS-IS processes, to develop TO-BE processes, to select the best suitable alternative by the help of BPR (Business Process Reengineering) Methodology, Decision Tree Analysis and Weighted Objective Method and finally, TO-BE processes of the Retail Market are mapped.Article Citation Count: 3A taxonomy of lean six sigma and agile methodologies used in software development(International Research Publication House, 2018) Erkan, Turan Erman; Erkan,T.E.; Industrial EngineeringSix Sigma is a business reasoning that highlight ongoing change, in light of a factual measure of instability. Lean is a persistent system to enhance execution, concentrating on waste disposal. Agile is methodology for extend administration, which can be utilized to control programming and item improvement utilizing redundant practices. This methodology can fundamentally build efficiency and decrease time to market. For the most part, lean and Six Sigma concentrate on taking out waste and giving the most elevated quality items and administrations with minimal cost, while encouraging an effortless, quick improvement approach. In this study, we will survey the existing literature in Six Sigma, Lean, Lean Six Sigma and Agile strategy over the past ten years. We analyze published research in the ranges of programming improvement. The audit is construct just with respect to the forty six (review) articles published between 2003-2017 academic literature. © International Research Publication House.
