Evaluation of the technical status of ship equipment based on the improved TOPSIS method

Abstract

The reliability of ship equipment is the basis for the safe navigation of ships and the completion of various tasks, and mastering the reliability level of ship equipment and assessing its technical status is the decision-making basis for ship maintenance and support; most of the current related research is based on combing statistics, and the accuracy is affected by the size of the sample data, and there are inevitable errors; in order to obtain more accurate assessment results, THIS paper introduces TOPSIS The method also improves the determination method of index weight and ideal solution, quantifies the assessment results, and achieves objective and accurate effects; through case verification, the model built in this paper has high accuracy, and on the basis of fully mining the potential information of the data, the accuracy and accuracy of the assessment are effectively improved, and can be applied to the technical status assessment of ship indicators.

A Study on the Measurement of Comparative Advantage of Land Use Efficiency, Spatiotemporal Heterogeneity and Its Influencing Factors—An Empirical Test from the Panel Data of China’s Provincial Sub-Industry Types

“…The TOPSIS principle optimizes the evaluation object by calculating the relative distance ranking between the alternative scheme and the ideal solution and the negative ideal solution, which has been widely used in the science and technology of system engineering decision analysis [26,27]. In this paper, in order to ensure that the evaluation results are objective and scientific, the entropy method is employed to determine the weight of evaluation indicators to improve the traditional TOPSIS and the efficiency of agricultural land and non-agricultural land are measured, respectively.…”
