Embodiment
[0060] This embodiment provides a method for assessing the benefits of port meteorological services, such as figure 1 As shown, the method for assessing the benefits of meteorological services in this port includes the following steps:
[0061] S1: Calculate disaster risk reduction benefits;
[0062] The calculation of disaster risk reduction benefits includes calculating the comprehensive strength index of port hazard-causing factors and calculating the comprehensive vulnerability index of port hazard-bearing bodies;
[0063] The calculation of the port disaster-causing factor comprehensive strength index is determined by principal component analysis of the preset index data, and its expression is:
[0064] H=a*PC1+b*PC2 (1)
[0065] Among them: H is the comprehensive intensity index of port hazard factors; a is the variance contribution rate of the characteristic root of the first hazard factor, b is the variance contribution rate of the characteristic root of the second h...

The invention provides a port meteorological service benefit evaluation method, which is used for solving the problem that the port meteorological service benefit cannot be comprehensively evaluated at present. The method comprises the following steps of: calculating disaster risk reduction benefit, wherein the disaster risk reduction benefit calculation comprises calculation of a port disaster-causing factor comprehensive strength index and calculation of a port disaster-bearing body comprehensive vulnerability index; calculating a port disaster-causing factor comprehensive strength index, and determining the port disaster-causing factor comprehensive strength index by performing principal component analysis on preset index data; calculating the vulnerability index of the port disaster-bearing body, and determining the vulnerability index through the probability of occurrence of port disaster-causing factors and the damage rate of the disaster-causing factors; calculating the operation time extension benefit; calculating the operation time extension benefit comprises calculating the hourly output value of a wharf and a ship company, calculating the total cost of the hourly outputvalue of a port, and calculating the control time shortened through the professional meteorological service of the port. By the adoption of the method, benefit evaluation can be conducted on the portfrom the two aspects of disaster risk reduction and operation time prolonging, rapidness and intuition are achieved, and business can be achieved.
Description
technical field [0001] The invention relates to the technical field of weather service evaluation, in particular to a method for benefit evaluation of port weather service. Background technique [0002] The growing demand for professional meteorological services has brought great opportunities and challenges to the meteorological departments of coastal port cities. [0003] Weather has a serious impact on port production and operations. Common disastrous weather such as strong winds, sea fog, lightning, and typhoons have brought safety problems to normal channel passage and port operations. The impact of high-impact weather on ship travel and port operations can be divided into anchorage ship berthing, coastal waterway ship travel, ship entry and departure scheduling, and ship cargo loading and unloading, and different types of ships have different berthing high wind control standards. Due to different fog control standards in port areas, today's port and shipping operation...
