  Risk Analysis of Ports in Maritime Industry in Turkey using FMEA Based Intuitionistic Fuzzy TOPSIS Approach

  Senel, Mine; Senel, Bilgin; Havle, Celal Alpay

  Today, international trade is extremely important for countries' economies. It is possible to show the ship's transport as one of the most important execution channels of this trade. International commercial maritime transport subject to many rules and regulations carries many risks in processes such as loading, handling and unloading. Commercial ports are the places where these risks are seen intensely. From this point, many risk components in terms of the process in the port, one of the international commercial port in Turkey, based on a risk analysis is tried to be evaluated in this study. Especially, loading and unloading processes are focused with the directions of industrial experts. The main dimensions of the risks in the port are determined via expert opinions, and the sub-criteria of these dimensions are revealed. In this way, a generic model is proposed based on failure mode and effect analysis and the model is digitized using intuitionistic fuzzy TOPSIS. Interpretations are made in the direction of the obtained analysis results.

  Risk Assessment with Failure Mode and Effects Analysis and Grey Relational Analysis Method in Plastic Injection Process

  Ünlükal, Ceren; Senel, Mine; Senel, Bilgin

  This study aims to evaluate the risks that may arise during the production process in a plastic injection manufacturing enterprise with traditional Failure Mode and Effect Analysis (FMEA) and Grey Relational Analysis (GRA). Although it is a widely used analytical technique that helps to identify and reduce the risks of failure in a process, the Failure Mode and Effects Analysis (FMEA) has some drawbacks that the different risks can have the same risk priority values and the weight of risk factors is not take into consideration. This situation has been tried to be eliminated by integrating the FMEA with the GRA. As a result, it is seen that the order of risk priority values of the identified failure changes according to both methods.

  Business Process Reengineering with Simulation Method

  Şenel, Mine; Şenel, Bilgin; Akan, Yaprak

  The aim of this study is to establish the Turkish Lokomotif Sanayi A.Ş., which serves as the locomotive of the Turkish Heavy Industry. (TÜLOMSAŞ) 14 bench, 30 personnel and bogie workshop business process change engineering methods by using simulation models suitable for Hammer Champy model, to renew the processes, to utilize the technology more while renewing the processes and to produce much better quality products. To do this, six scenarios were developed by considering the constraints of the factory and all the business processes which were either feasible, but whose operation was uncertain, and models were created by using the computerized ARENA 9.0 Simulation program in this scenario. As a result of total 12 months of change engineering engineering applications, the scenario giving the closest result to the most applicable targets was selected and the annual bogie amount was increased to 2164 with the scenario selected while the annual bogie amount was 2029 before the change engineering application. With this study, the change that will be realized with the change engineer applications in the railway sector will be able to eliminate all the uncertainty states with the established simulation models and to examine the business processes in detail.

  The improvements on service quality of Turkish railway corporation (TCDD) in the process of reorganization

  Şenel, Mine; Şenel, Bilgin; Özkara, Belkıs

  This study has been conducted to assess the perceived service quality of Turkish Railways Corporation (TCDD), which is in the process of reorganization. For achievement of the purpose of the study, the relationships between service quality and demographic characteristics of customers have been examined and the results have been compared to the service quality measurements done in 2004. Perceived service quality is measured using widely accepted SERVQUAL scale that is developed by Parasuraman, Zeithaml and Berry. Data has been collected from primary sources. Respondents have been given the statements in proportional way. Data analysis is performed by reliability checks, computation of means, t-test for independent samples and finally ANOVA (Analysis of Variance). Using the results, the most important dimension for respondents is selected among the five dimensions of service quality. It has been observed that there are meaningful improvements in the each of service quality dimensions from angel of the amount of investments. However, it is also seen that the improvements are not enough and customers expect more than current service quality in all the dimensions of service quality.
