Determination of Key Performance Indicators for Measuring Airport Success: a Case Study in Libya
(Elsevier Ltd, 2018) Eshtaiwi,M.; Badi,I.; Abdulshahed,A.; Erkan,T.E.; Industrial Engineering
Airports 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 Ltd
Layout Improvement Method Selection for a Mass Production Facility
(IEOM Society, 2018) Baç,U.; Erkan,T.E.; Industrial Engineering
Purpose 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.

A Taxonomy of Lean Six Sigma and Agile Methodologies Used in Software Development
(International Research Publication House, 2018) Badwe,S.; Erkan,T.E.; Industrial Engineering
Six 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.
