The growth of the domestic economy has led to the development of the inland water transportation.While inland shipping companies are actively developing the route to the river lanes,small-scale interior shipping companies have also shown rapid development.The development of the river canal has shown a strong pattern of economic growth,but this model has brought a lot of security to the river.The rapid growth of the river's shipping economy and the lag of the river lanes have made a big difference.The severity of the development has led to a reduction in the safety of the river and frequent accident.For this phenomenon,the country has also begun to focus on the safety of the inland water transportation while the river is heavily development.The safety research of inland water transportation is mainly to analyze the influencing factors of inland shipping safety.To establish a system of indicators and assess the safety of the interior shipping.How to analyze the factors that affect the safety of the river's shipping safety and use a certain method to determine the system's full-scale measurement of the system,Is the key to studying the safety of the river and the core of this paper.Here are the main findings of the paper.1)On the basis of the previous inland shipping safety indicators,the index points out the importance of the system's safety assessment for the internal canal.And analysis of the lack of safety assessment system in the original river.In analyzing the factors that affect the safety of the river's shipping safety,the introduction of Man-Machine-Environment System Engineering.Comprehensive research has comprehensively analyzed the impact of the human,ship's,environment and management on the safety of the river shipping safety.2)The result of the analysis of the security factors of the inland shipping safety factors,based on the principles set up by the index,was originally constructed by the inland revenue index of the inland revenue safety index.The data in the index came mainly from the incident data recorded by the Yangtze marine bureau in recent decades.And combine the results of professional surveys with professionalquestionnaires and consult experts in relevant areas to determine the value of the indicators.By analyzing the value of each indicator to the extent of the safety of inland water transportation,the scale of the performance of the ship will be graded.3)For rough set theory and the algorithms that are based on rough set theory and algorithms.Before filtering the index,through building indiscernibility relationship and data discretization to preprocess data.Through the Rosetta crude software,using a crude-scale matrix based on rough-sets matrices,The sub-committee of the inland revenue safety index of the inland revenue index is about to be conducted.Calculations calculated the weights of the indicators in the post-index system and analyzed the results of the index.Finally,we can get the river's something index of the inland shipping safety index.
