Conference Object Enterprise Resource Planning Implementation Differences Within the Same Methodology - Case Study From West Europe and Turkey(Acad Conferences Ltd, 2011) Erkan, Turan ErmanEnterprise Resource Planning (ERP) systems are vital for competitive edge in today's business world. ERP is an integrated information system that serves all departments within an enterprise. Therefore, business processes should be optimised before ERP implementation in order to catch a perfect implementation. Before year 2000 all the giant firms realised their ERP projects and after that best practises took place. After those trial and error based experiences, ERP vendors need to form an ERP implementation methodology. Big ERP vendors developed implementation methodologies, they were almost the same; starting from project preparation to selection, implementation to maintenance and control. Those project methodologies improved the success rate of ERP implementations. This research is both empirical and qualitative. In fact it consists of two monographic researches. They are both about ERP implementations in the same sector. One of the firms is a national one and other one is a multinational one. Both implementations done by the same consultant team with the same methodology, so the evaluation of the project is more objective than any other questionnaire based ones, which are filled by different implementation teams. The findings of the comparison are surprisingly different from each other within the implementations, although they both used the same methodology. Basic steps of the ERP implementation such as: project preparation, business blueprint, realization, final preparation and go live & support differs from each other both in national and multinational firms. The major difference is seen in the first steps which are project preparation and business blueprint. Multinational firm seems to have more chance than the national one in achieving organisational efficiency through successful ERP implementation. The research outcome is useful for professionals running implementation projects and those making decisions on ERP implementation. The results can also be used by practitioners managing ERP projects in order to avoid from implementation methodology illusion.Conference Object Intellectual Capital Management's Effects on Enterprise Resource Planning Implementation(Acad Conferences Ltd, 2012) Erkan, Turan Erman; Ozdemir, Yavuz Selim; Bac, UgurThe implementation of an Enterprise Resource Planning (ERP) system can be one of the most important strategic decisions an organization undertakes. An implementation of ERP system has effects on improving all over system performance. However, there are many factors affecting the performance of ERP implementation and these factors have to be inspected in accordance to some performance measurements and metrics. Intellectual Capital Management (ICM) is one of the most important factors of ERP implementation. The ICM literature has produced tens of models to support the various ICM activities, such as identification, measurement, valuation, acquisition and reporting of intellectual capital. However, the practice of applying various ICM models seems to be a fairly new issue in many countries and organizations. Turkey is one of those countries that has just been introduced with ICM. Using an ICM system has different effects on the implementation of an ERP system. In this study, a questionnaire based research has been made on Turkish enterprises to analyze ICM'S effects on ERP implementation. Also, we made a cross industrial research and determined those effects in different manufacturing sectors such as electronics and food sectors. Questionnaire results have been analyzed with statistical methods to summarize the current situation. The results of this study can be used to compare the effects of implementation of ERP systems in different industries in Turkey. Understanding of this relationship is very important for current or future ERP implementations. Also these results can be used in the comparison of international differences of the effects of ICM on ERP implementation process.Article Citation - WoS: 44Citation - Scopus: 70Selection of Academic Staff Using the Fuzzy Analytic Hierarchy Process (fahp): a Pilot Study(Univ Osijek, Tech Fac, 2012) Rouyendegh, Babak Daneshvar; Erkan, Turan Erman; Industrial Engineering; Computer 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 - WoS: 247Citation - Scopus: 350Supply Chain Performance Measurement: a Literature Review(Taylor & Francis Ltd, 2010) Akyuz, Goknur Arzu; Erkan, Turan ErmanThis paper is intended to provide a critical literature review on supply chain performance measurement.

Turkish case is no exception to this change. Beginning with 2000's, Turkish government initiated a new program for a renewed distribution of authorities between central and local governments resulting in rescaling of Turkish state. New authorities and responsibilities were decentralized to local governments. As the local governments in Turkey became the locus of all political activities, debates concerning institutional capacity of them became wide-spread. It has been widely argued that although increasing number of authorities were transferred to local governments; they lack necessary institutional capacity and know-how to manage increasing number of responsibilities and changing spatial structure. For this respect, the problem with local governments in Turkey has three facets. First of all, decision-making mechanisms of local governments is weak, both process wise and with regards to rationality, accountability and transparency. Mostly, political patronage is more influential than good governance. Secondly, implementation level of innovative information systems in decision making-mechanism with regards to spatial issues, service production and public participation is poor. For instance, although information systems like UIS (Urban Information systems), IAM (Intangible Asset Management), IRP etc. are used, they are either poorly integrated to management system or became obsolete because of lack of proper performance measurement and evaluation. In Turkish case there is a clear gap between management practices of local government service delivery and use of innovative information systems. In this paper, it is aimed to portray the underlying dynamics and problems behind ineffective use of innovative information systems in local governments in Turkey. For this purpose, one of the largest and well-known district municipalities of Turkey, Cankaya Municipality in Ankara is taken for a case study. Cankaya Municipality's technological capacity and use of innovative information systems is assessed in terms of accountability, decision-making, and public participation. Results of the assessment will be used to develop some strategies and tools for improving municipality's capacity to make better use of information systems.Conference Object Selection of Erp System Using Qfd Approach: a Pilot Study From Turkey(Acad Conferences Ltd, 2012) Ictenbas, Burcu Devrim; Rouyendegh, Babak Daneshvar; Erkan, Turan ErmanToday companies face the challenge of increasing competition, expanding markets and rising competition. Many organizations seek to improve their competitiveness by utilizing advanced information technology, such as Enterprise Resource Planning (ERP) systems. Selection of appropriate ERP system is a vital decision for any enterprise in this intense competitive environment. The selection process is complicated since complexity of ERP systems and too many alternatives. Requirements analysis of a software system like ERP is often considered to be one of the most important steps in the software selection process. Quality Function Deployment (QFD) is a methodology to translate customer requirements into the final product or service characteristics. In spite of successful applications of QFD in familiar fields such as product planning, education quality and service quality, the usability of QFD in the selection of software systems have been seen in only few studies. The purpose of the study is to determinethe most important technical attributes of the ERP systems from the end - users' perspective using QFD methodology. The developed framework integrates ERP characteristics obtained from vendors in the market and the list of customer requirements by taking into account the company profile and strategic selection criteria. The solution proposed in this study will support decision makers to manage the early stages of ERP selection according the company's needs.Article Citation - WoS: 14Citation - Scopus: 16Assessment of Airport Performance Using the Grey Theory Method a Case Study in Libya(Emerald Group Publishing Ltd, 2017) Eshtaiwi, Mohamed Ibrahim; Badi, Ibrahim A.; Abdulshahed, Ali M.; Erkan, Turan ErmanPurpose - Performance evaluation of airports or any other organisation is paramount for improving performance.

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 - WoS: 2A Model To Evaluate Supply Chain Performance and Flexibility(Academic Journals, 2011) Bac, Ugur; Erkan, Turan ErmanIn present day's global competitive environment, enterprises have to focus on their supply chain performance to have a competitive advantage. Improving the effectiveness of the system is the only way to do so and, for this purpose, ongoing supply chain activities have to be inspected in pursuant of some performance measurements and metrics to cover the concept. There is a lack of effective mathematical models in the literature which enclose flexibility and its parameters in order to measure the performance of a supply chain by considering all of its vital elements. In this paper, a mathematical model is proposed to evaluate supply chain performance using some key performance indicators. This model can be used to evaluate the flexibility characteristics of logistic, market, supplier, machine, labor, information system, and routing of the supply chain.
