A Methodological Framework for Evaluating Maritime Simulation

Vasilakis P., Nikitakos N. V.

TransNav : International Journal on Marine Navigation and Safety of Sea Transportation

2012

Vol. 6, no. 1

27--32

The application of simulation courses according to STCW conversion is addressed to the edu-cation of marine deck and engine officers in order to familiarize with the working environment, emergency contingency training and trouble shooting. This paper presents a framework which evaluates the participants in the courses of simulator, according to their concerns and their level of use. Actually this framework is an innovative concept which tries to identify how the contributors think and work in this virtual environment. The results from the application of this framework are presented in this paper, based on student’s concerns, reactions and level of use with respect to the exercise and efficiency of simulation training courses taken place at the Merchant Marine Academy of Engine Officers on Chios Island. The main goal of our research is to promote a general framework which can be easily applied in any marine simulation curses and will be very useful to the instructor for reorganizing, redesigning and finally configurating the Simulation Courses accord-ing to their participant.

A methodology for rating and ranking hazards at formal safety assessment using fuzzy logic

Dourmas G. N., Nikitakos N. V., Lambrou M. A.

Archives of Transport

2007

Vol. 19, iss. 3

75-86

Formal safety assessment of ships has attracted great attention over the last few years. This paper, following a brief review of the current status of marine safety assessment, is focused on the hazards identification (HAZID) and prioritisation process. A multicriteria decision making framework, which is based on experts' estimation, is then proposed for hazards evaluation. Additionally, in this paper many aspects of the evaluation framework are presented, including: the synthesis of evaluation teams, the assessment of the importance of criteria, the evaluation of the consequences of the alternative hazards, and the final ranking of the hazards. The proposed methodology has the innovative feature of embodying techniques of fuzzy logic theory into the classical multicriteria decision analysis. The paper concludes by exploring the potentiality of the above methodology in providing a robust and flexible evaluation framework suitable to the characteristics of a hazard evaluation problem.

Artykul, po krótkim przeglądzie aktualnego stanu oceny bezpieczeństwa morskiego, skupia się na identyfikacji i rankingu zagrożeń. Zaproponowany jest także, oparty na opinii ekspertów, schemat wielokryterialnego podejmowania decyzji przy ocenie i porządkowaniu zagrożeń. Przedstawionych jest wiele aspektów tego schematu, włączając syntezę zespołów oceniających, ocenę konsekwencji alternatywnych zagrożeń i końcowe uporządkowanie zagrożeń. Proponowaną metodologię cechują właściwości innowacyjne polegające na połączeniu teorii logiki rozmytej i klasycznej wielokryterialnej analizy podejmowania decyzji.
