Increase of global trade brings the need of higher transportation capacity as bigger ships and port facilities. Port construction and expansion investments can be said to be supply to meet demand. Maritime safety is one of the factors affecting the zoning plan approval process in the port construction and extension investments. These factors mostly caused by the ship maneuver. One of the most widely used models is the Environmental Stress (ES) Model in risk assessment of navigation and ship manoeuvre. ES Model measures the risk occurring around the ship during the berthing / unberthing manoeuvres performed in the simulation environment with the ports and ships that are modeled similar to the port project. But, it is not certain which parameter of the port project will be revised such as ship tonnage and length of the ship, port form and size etc. The main benefit of this study is taking precaution with measuring risk by specifying the risk factors and their weights using both ES Model and fuzzy logic method. Thus, the development plan and project evaluation process, which is under the duty and responsibility of the Turkish Ministry of Transport, will be carried out in terms of safety with the method proposed in this study. Another important contribution of this study is its originality in terms of clarification of raw outputs of ES model reports by using fuzzy logic method in scientific literature. So, the revised port project will be realized by providing maritime safety. While port projects are approved by the Ministry of Transport within the scope of the legislation that determines the port planning process in question, the evaluation of Modeling Reports with fuzzy logic method will contribute to both fast and safe project design process. 2019-01-01T00:00:00Z https://hdl.handle.net/20.500.12960/1210 The Bimini Ghost Maps of William P. Cumming McIntosh, Gregory C. Five manuscript maps of the early sixteenth century have been noted in the literature of the history of cartography for the place-name Bimini where Florida is today. An examination of the sources for these references reveals there are only two such maps. The other maps - bibliographical ghost maps - arose because of reliance upon secondary sources.

Cubic nano-crystals coated with an ultra-thin Cu layer can be readily obtained when Ni cubic nanoparticles are used as the seeds. At elevated temperatures, the Cu seed with extending Ni branches preserves its shape compared to the Ni seed with extending Cu branches. 0000-0001-6008-8321; 0000-0001-6321-6501; 0000-0003-0553-9032; PubMed: 30444499; WOS:000451737900025 2018-01-01T00:00:00Z https://hdl.handle.net/20.500.12960/1208 A methodology proposal for supplier performance evaluation: Fuzzy DEMATEL method with sustainability integrated SCOR model Büyüksaatçi, Kiriş Sinem; Yılmaz, Börekçi Dilek; Koç, Tuğçe Overall performance of an organization’s supply chain depends on each one of the coordinated and collaborated chain partners’ performance. Therefore, supplier evaluation and development is a prerequisite that should be accomplished, since the performance of the suppliers, as the up-stream actors, will affect the competitiveness of the entire supply chain. SCOR is a reference model that is widely used for evaluating and comparing supply chain activities and performance. The model provides a framework of standard processes to guide architecture, standard metrics to measure the performance and management practices and technology to lead supply chain partners. The performance section of the model focuses on five performance attributes: reliability, responsiveness and agility for customers; costs and asset management efficiency for internal. Each attribute has a group of metrics to measure the related performance. Although the SCOR model provides various metrics related to both operational and financial performance, it lacks the ability to measure environmental as well as social aspects. This is a handicap since the requirements for the sustainable performance management of suppliers are becoming increasingly relevant. In this study, the sustainability integrated SCOR model approach is proposed for supplier performance evaluation. The fuzzy DEMATEL method is used in the analyses. The aim of this approach is to analyze and reveal the causal relationships among performance metrics, and also to prioritize these metrics according to their level of influence. © 2020, Springer Nature Switzerland AG. 2-s2.0-85069441676 2020-01-01T00:00:00Z
