Embodiment Construction

[0058] The technical solution of the present invention will be further introduced below in conjunction with specific implementation methods and accompanying drawings.

[0059] This specific embodiment discloses a method for assessing waterway traffic safety risks based on the AHP-entropy weight method, such as figure 1 shown, including the following steps:

[0060] S1: Determine the risk factors of waterway traffic safety. Starting from the three factors of ship, environment and management, construct the waterway traffic safety risk assessment index system. As shown in Table 1, the waterway traffic safety risk assessment index system is divided into target layer, criterion layer and Index layer, where the criterion layer includes four first-level indicators of natural environment, navigation environment, ship and management, and each first-level indicator includes several second-level indicators.

Abstract

An AHP-entropy weight method-based channel traffic safety risk assessment method disclosed by the present invention comprises the following steps of S1 determining the channel traffic safety risk factors, based on the three factors of the ship, the environment and the management, constructing a channel traffic safety risk assessment index system which is divided into a target layer, a criterion layer and an index layer; S2 according to an AHP method, calculating the weight of the index layer relative to the target layer, and verifying the overall consistency, and then calculating the index weight according to an entropy weight method, and carrying out the combination weighting calculation according to a CWM method to obtain the index comprehensive weight; S3 determining a channel traffic safety risk level characteristic value according to a variable fuzzy method. According to the present invention, by constructing the channel traffic safety risk assessment index system, the safety riskassessment aiming at the channel water area is realized, based on the risk assessment results, the management and control resources are distributed reasonably, and finally, the channel traffic accidents are reduced and avoided.

Description

technical field [0001] The invention relates to the field of water traffic safety risk assessment, in particular to a waterway traffic safety risk assessment method based on the AHP-entropy weight method. Background technique [0002] Water transportation has the characteristics of high risk, which is more prominent in accident rate and destructiveness. In recent years, with the development of the shipping industry, the number, type and tonnage of ships have undergone tremendous changes, which put forward higher requirements for the carrying capacity and risk management level of the waterway. According to the FSA (Formal Safety Assessment) method formulated by the International Maritime Organization (IMO), water traffic risk management is divided into five steps: risk factor identification, risk assessment, risk control plan formulation, cost and benefit assessment, and decision-making recommendations. [0003] At present, the prior art scheme closest to the present inventi...
