Identification of weak links in the ECDIS - operator system based on simulator training

Pipchenko O., Burenkov O., Tsymbal M., Pernykoza V.

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

2021

Vol. 15 No. 1

83--88

Statistics, based on grounding incident investigations, is not always sufficient for retrieving objective information and designing comprehensive solutions for improving the ECDIS training process for deck officers and development of methods aimed at reducing the grounding incident rate and improving the effectiveness of navigation. The research studies statistics on deck officers` errors made during training on bridge simulators equipped with ECDIS and provides an analysis of errors distribution among navigators of different ranks. The study shows that in event of the EPFS (Electronic Position Fixing System) failure the likelihood of grounding increases dramatically for all deck officers, irrespective of rank and experience, despite having fully functional radar and ECDIS in dead reckoning mode.

Development of a computational model of a lightweight vertical lathe with the use of superelements

Powałka Bartosz, Dolata Michał

Archives of Mechanical Technology and Materials

2019

Vol. 39

1--6

This article presents a process of developing a computational model of a light construction vertical lathe. The model is made using the finite elements method. Due to the complexity of the machine tool and the optimization of the computation time superelements have been used in the model. The application of this method has reduced the computation time allowing the analysis of many variants of the mutual position of the machine components. The results of the analyzes led to the indication of weak links of the machine tool. After the improvement of the machine tool construction the movement of the tool tip and the workpiece was much smaller.

A note on modifications to the methodology for components in the complex technical systems reliability structure importance evaluation

Chybowski L.

Journal of Polish CIMAC

2011

Vol. 6, no 2

59-64

The paper presents State-of-the-Art in topic of reliability importance analysis for components and groups of components in complex technical systems (CTS). Basic importance evaluation measures for finding so called “weak links” in system structure have been discussed. Quantitative and qualitative importance analysis methods have been presented. Range of applicability of these methods have been pointed out. Some results of importance evaluation with use of Birnbaum’s and Vesseley-Fussell’s measures based on the example of 2-phased complex marine system have been shown. Critically conclusions on currently known importance analysis methods have been presented.
