As shown in fig. 1, the method specifically comprises the following steps:
s1: acquiring self state data of the ship in the current shipping; the ship self state data comprises ship load, ship crew and ship depreciation rate.
S2: estimating and calculating to generate a shipping route according to the starting point position data and the end point position data of the current shipping, and acquiring relevant data of a route on the shipping route; the relevant data of the air route comprises air route distance, air route sections, air route average speed limit and air route heading.
S3: and inputting the state data of the ship and the relevant data of the air route into a set cost estimation model, generating the ship shipping cost of the current shipping through estimation and calculation of the cost estimation model, and displaying the estimated ship shipping cost information.
In the actual calculation process, the ship shipping cost is estimated and calculated through the ship self state data and the air route related data, and the ship load, the ship crew and the ship depreciation rate of the ship self state data, and the air route distance, the air route flight segment, the air route average speed limit, the air route course and other parameters of the air route related data are all key parameters influencing the ship shipping cost. Secondly, the ship shipping cost is estimated and calculated only by acquiring the state data of the ship and the relevant data of the air route, and the parameters can be acquired before the shipping is started, so that the estimation of the ship shipping cost can be realized before the shipping is started, and the management effect of the ship shipping can be assisted and improved. Furthermore, the ship self-state data and the relevant data of the air route are input into the cost estimation model, so that the ship shipping cost can be estimated, calculated and generated and displayed.
In a specific implementation process, in step S3, the cost estimation model estimates and calculates the shipping cost of the ship by the following formula:
C＝a1λ1+a2λ2+a3λ3+a4λ4+a5λ5+a6λ6+a7λ7in the formula, λ1And a1Respectively representing the ship load and the coefficient thereof; lambda [ alpha ]2And a2Respectively representing the ship crew and the coefficients thereof; lambda [ alpha ]3And a3Respectively representing the ship depreciation rate and the coefficient thereof; lambda [ alpha ]4And a4Respectively representCourse distance and its coefficient; lambda [ alpha ]5And a5Respectively representing the flight path sections and coefficients thereof; lambda [ alpha ]6And a6Respectively representing the average speed limit of the air route and the coefficient thereof; lambda [ alpha ]7And a7Respectively representing the course heading and its coefficients.
In the invention, the cost pre-estimation model pre-estimates and calculates the shipping cost of the ship through the formula, namely the pre-estimation model realizes the pre-estimation calculation of the shipping cost of the ship through the comprehensive calculation of parameters such as the ship load, ship crew and ship depreciation rate of the state data of the ship, the route distance, route section, route average speed limit, route course and the like of the relevant data of the route, thereby accurately pre-estimating and obtaining the shipping cost of the ship; compared with manual calculation, the pre-estimation calculation mode has the advantages of high pre-estimation calculation efficiency and good pre-estimation accuracy. In this embodiment, the coefficient a1～a7The method is calibrated by historical data, such as:
first, the following settings are made: 1) let the weight of the ship load be λ1Ten thousand tons; 2) recording the number of ship crews as lambda210 pieces of; 3) recording ship depreciation rate as lambda310% of the total weight; 4) recording course distance as λ410 km; 5) marking the course flight segment as lambda5A segment; 6) recording average speed limit of route as lambda610 km/h; 7) recording course of course as λ71 ═ forward flow, λ72-counterflow; 8) the ship shipping cost is recorded as C ten thousand yuan.
Then, at least one time of history data, namely at least seven lambdas, is obtained1～λ7And its corresponding C.
Finally, the obtained lambda1～λ7And the corresponding C is substituted into the formula C ═ a1λ1+a2λ2+a3λ3+a4λ4+a5λ5+a6λ6+a7λ7In (1), the coefficients a are respectively calculated1～a7And obtaining a pre-estimation calculation formula of the cost pre-estimation model.

Shipping fuel costs are one of the major costs of shipping (fuel) ships, as each shipment requires the consumption of a large amount of fuel. In the process of estimating and calculating the shipping fuel cost, the shipping speed is calculated through the average speed limit of the air route and the course pre-estimation of the air route, then the average fuel consumption of the ship in the process of shipping is calculated according to the shipping speed and the ship load pre-estimation, and finally the shipping fuel cost is estimated and calculated according to the average fuel consumption of the ship and the air route distance. In the invention, each parameter for estimating and calculating the shipping fuel cost is an important parameter influencing the shipping fuel cost, wherein: 1) the average speed limit of the course defines the highest shipping speed of the shipping of the ship, and the course is the 'downstream' or 'upstream' considering the shipping, so the two parameters can determine the shipping speed of the ship to a certain extent; 2) the consumption of the fuel oil has a corresponding curve relation with the shipping speed and the weight-average load of the ship, so that the two parameters can determine the average oil consumption of the ship to a certain extent; 3) the combination of average ship fuel consumption and course distance corresponds to the shipping fuel cost.
In the specific implementation process, the cost pre-estimation model pre-estimates and calculates the shipping speed of the ship according to the average speed limit of the air route and the course of the air route, then pre-estimates and calculates the shipping time length according to the shipping speed and the distance of the air route, and finally pre-estimates and calculates the ship depreciation cost according to the shipping time length and the ship depreciation rate.
Ship depreciation costs are one of the main costs of shipping a ship, as each shipment is a cost per ship, which makes the ship closer to scrapping, thereby changing the remaining value of the ship. In the invention, each parameter for predicting and calculating ship depreciation cost is an important parameter influencing the ship depreciation cost, wherein: 1) the average speed limit of the course defines the highest shipping speed of the shipping of the ship, and the course is the 'downstream' or 'upstream' considering the shipping, so the two parameters can determine the shipping speed of the ship to a certain extent; 2) the combination of the shipping speed and the route distance corresponds to the shipping time length; 3) the duration of the shipping is the most important factor influencing the ship depreciation rate, so the ship depreciation cost can be well estimated and calculated through the combination of the duration of the shipping and the ship depreciation rate.
In the specific implementation process, the cost prediction model calculates the position of an shipping stop point according to the route distance and the route section prediction, and then calculates the shipping stop cost according to the position of the shipping stop point and the corresponding cost prediction.
The shipping berthing fee is one of the primary fees for the shipping cost of the vessel because the berthing fee is paid at the shipping berthing points. In the invention, each parameter for pre-estimating and calculating the shipping and parking cost of the ship is an important parameter influencing the shipping and parking cost, and the position of the parking point and the parking cost of the current shipping can be obtained by inquiring the distance and the section of the airline, so that the shipping and parking cost can be well pre-estimated and calculated according to the position of the parking point and the parking cost.
In the specific implementation process, the cost pre-estimation model pre-estimates and calculates the shipping service cost according to the ship crew and the corresponding cost thereof.
Shipping service costs are one of the major costs of shipping a ship, and each crew (ship crew) in the shipping process needs to pay. In the invention, each parameter for predicting and calculating the shipping service cost is an important parameter influencing the shipping service cost, and the shipping service cost can be well predicted and calculated by inquiring the ship crew and corresponding wages thereof.
