Embodiment 1

[0155] For the selection of the ship routing system plan in the core port area of ​​Ningbo-Zhoushan, there are 6 candidate plans initially determined. The efficiency index evaluation values ​​of the 6 candidate plans in the evaluation system are shown in Figure 5 .

[0156] The following are the specific evaluation steps of 6 candidate programs:

[0157] The first step: quantitative index weight and normalization calculation.

[0158] Using the aforementioned entropy method to calculate formula 1, formula 2, formula 3, and formula 4, obtain the efficiency index weight E of the 6 candidate schemes 1 2 , E 2 2 , E 3 2 , E 4 2 , E 5 2 , E 6 2 , E 7 2 , E 8 2 , E 9 2 Respectively: 0.139566429, 0.138641607, 0.140569862, 0.04758846, 0.123870012, 0.135423364, 0.139236745, 0.000111896, 0.134991625; for efficiency and cost index conversion and normalization processing, the calculation is as follows Image 6 The normalized value of the efficiency index shown.

Abstract

The invention provides a comprehensive evaluation index system of a ship routing scheme and a combined evaluation method thereof. The comprehensive evaluation index system comprises a quantitative index and a qualitative index, wherein, the quantitative index comprises an efficiency index and the qualitative index comprises a safety index and a performance index. The combined evaluation method comprises the following steps: determining a qualitative evaluation index value by a group decision making method; determining a quantitative index value of the scheme by an entropy method and a fuzzy analytic hierarchy process (FAHP); and realizing ordering and optimization of the scheme based on a technique for order preference by similarity to ideal solution (TOPSIS). Compared with the traditional comprehensive evaluation index system of the ship routing scheme and the evaluation method thereof, the comprehensive evaluation index system and the evaluation method thereof of the invention increase analysis evaluation of the quantitative index, thus the index system is more complete; and by combination of quantitative evaluation and qualitative evaluation, expert knowledge is integrated into the decision-making process preferably, thus being more practical and more flexible.

Description

Technical field [0001] The invention relates to the comprehensive evaluation and selection of a ship routing system plan, and specifically relates to a comprehensive evaluation index system and a combined evaluation method for a ship routing system plan. Background technique [0002] At present, in the ship traffic management system, the ship routing system and the traffic separation system play an increasingly important role, becoming an indispensable part of the ship traffic management system. However, the evaluation of ship routing system and traffic separation schemes is still in its infancy. It is basically based on navigation experience and qualitative analysis. It lacks a theoretical system and quantitative analysis and evaluation. So far, there are only a few ship routing systems in my country. The traffic separation system was adopted by the International Maritime Organization (IMO). [0003] The traditional evaluation model based on navigation experience and qualitative a...
