Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of data processing, and in particular to an iron-making raw material skin return mode switching method and device, electronic equipment and storage medium. BACKGROUND

[0002] Iron ore, coking coal and injection coal and other iron-making raw materials are usually transported into a steel plant by train and truck due to their large quantity. When transported by train, the gross weight is weighed when entering the plant, and the skin weight (train compartment weight) is deducted when leaving the plant. The net weight of the iron-making raw material is the difference between the gross weight and the skin weight.

[0003] The skin weight is divided into actual skin weight and nominal skin weight (designated skin weight of the compartment). However, due to long-term wear and tear and aging of the train, the actual skin weight is usually less than the nominal skin weight. If the actual skin weight is used to calculate the net weight of the iron-making raw material, the result is more accurate. If the nominal skin weight is used to calculate the net weight of the iron-making raw material, the result will be smaller. The enterprise switches between the actual skin weight and the nominal skin weight according to the needs of production and operation. The net weight of the iron-making raw material calculated under the two modes is different.

[0004] After switching between the two modes, if the iron-making raw material consumption index is not adjusted, there will be a phenomenon of inventory surplus or inventory loss during inventory checking. The prior art usually adjusts the iron-making raw material consumption index to achieve balance between income and expenditure by checking the surplus or loss tons after the phenomenon of inventory surplus or inventory loss occurs. However, it is difficult to accurately determine the surplus or loss tons of the iron-making raw material during checking. Therefore, how to adjust the quantity of iron-making raw material entering the warehouse and the consumption index after switching between the two modes to achieve balance between income and expenditure has become a technical problem to be solved.

[0030] In the following, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application, so that those skilled in the art can better understand the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of the present application.

[0031] Because of the large demand for iron ore, coking coal, injection coal and other iron-making raw materials, steel enterprises usually use trains to transport iron-making raw materials into the factory. When calculating the net weight of iron-making raw materials, the gross weight is subtracted from the tare weight. The gross weight is the total weight of the iron-making raw materials and the car body, and the tare weight is the weight of the car body. In actual application, according to the needs of production and operation, the tare weight sometimes uses the standard tare (the standard tare weight designed for the car body), and sometimes uses the actual tare (the actual tare weight of the car body). After the car body runs for a long time and is worn out, the actual tare is usually smaller than the standard tare. If the net weight of iron-making raw materials is calculated according to the actual tare, the net weight of iron-making raw materials is equal to the true weight. If the net weight is calculated according to the standard tare, the net weight is less than the true weight.

[0032] For example, if a train of iron ore is purchased, the total gross weight of the train is 10,000 tons when it is transported into the factory. If the net weight of the iron ore is calculated according to the actual tare, it is 9,000 tons, and the net weight of 9,000 tons is stored in the system. If the net weight of the iron ore is calculated according to the standard tare, it may be 8,000 tons, and the net weight of 8,000 tons is stored in the system. However, in fact, the net weight of a train of iron ore is the same, that is, the true weight of the iron ore may be close to 9,000 tons. Whether the iron ore is stored according to the actual tare or the standard tare, the weight of the finished iron product that can be produced after the iron ore in the warehouse is consumed is the same. Assuming that the iron product is 3,000 tons, the consumption index of the actual tare (the amount of iron ore consumed per ton of iron produced) is C1 = 9,000 / 3,000 = 3. When the standard tare is switched to storage, the iron ore is 8,000 tons. If the consumption is still calculated according to C1, 3,000 tons of iron product will consume 9,000 tons of iron ore. However, the system only stores 8,000 tons of iron ore, and the data of storage and withdrawal cannot achieve balance. In another case, assuming that the consumption index C2 = 8,000 / 3,000 ≈ 2.67 is calculated according to the standard tare, when the actual tare is switched, if the consumption is still calculated according to C2, 3,000 tons of finished iron product will consume 8,000 tons of iron ore. However, the system stores 9,000 tons of iron ore, and in theory, there will be 1,000 tons of iron ore left in the warehouse. However, in fact, it has been consumed, resulting in a discrepancy between the physical inventory and the balance, and the balance cannot be achieved. In addition, for iron ore suppliers, calculating the net weight according to the standard tare will result in a loss.

[0033] To solve the problems caused by the switching of different return skin modes, the present application provides a return skin mode switching method for ironmaking raw materials to accurately calculate the warehouse-in quantity of the ironmaking raw materials and accurately adjust the consumption index of the ironmaking raw materials when the return skin mode is switched, so as to achieve the balance between income and expenditure.

[0034] Embodiment one

[0035] Figure 1 A flowchart of a return skin mode switching method for ironmaking raw materials is provided for the first embodiment of the present application. The present embodiment can be applied to the situation of return skin mode switching of ironmaking raw materials. The method can be executed by a return skin mode switching device for ironmaking raw materials. The device can be realized in the form of hardware and / or software and can be configured in an electronic device. As shown in the figure, the return skin mode switching method for ironmaking raw materials includes the following steps. Figure 1

[0036] S101, determine the first return skin mode of the ironmaking raw materials to be warehoused and the raw material data, the raw material data including the first warehouse-in quantity, the train freight ratio and the first consumption index.

[0037] In the present embodiment, the ironmaking raw materials can be iron ore, coking coal, injection coal and other ironmaking raw materials required by a steel enterprise. The first return skin mode can be the current return skin mode of the ironmaking raw materials that have been warehoused. The raw material data can include the first warehouse-in quantity, the train freight ratio and the first consumption index. The first warehouse-in quantity can be the net weight of the ironmaking raw materials calculated by using the first return skin mode. The first consumption index can be the consumption index of the ironmaking raw materials under the first return skin mode. The consumption index can be the weight of the ironmaking raw materials consumed for producing a unit weight of finished product. The ironmaking raw materials can be transported by train and car at the same time. The train freight ratio can be the ratio of the total weight of the ironmaking raw materials transported by train to the total weight of the ironmaking raw materials (the total weight of the ironmaking raw materials transported by train and car).

[0038] In one embodiment, the transportation mode is usually set when the ironmaking raw materials are ordered. For example, the train freight ratio, the car freight ratio and the purchase quantity are set. When the ironmaking raw materials are transported into the plant by train carriages, the gross weight is weighed, and then the total net weight of the ironmaking raw materials is calculated as the first warehouse-in quantity according to the net weight calculation mode of the first return skin mode.

[0039] S102, when receiving an instruction to switch from the first return skin mode to the second return skin mode, obtain the warehouse-in correction coefficient and the consumption index correction coefficient of the ironmaking raw materials.

[0040] ​In the embodiment, if the first skin return mode is full skin return, the second skin return mode is marked skin return, and if the first skin return mode is marked skin return, the second skin return mode is full skin return. When the switching instruction of the skin return mode is received, the storage correction coefficient and the consumption index correction coefficient of the ironmaking raw material can be obtained. Specifically, the storage correction coefficient and the consumption index correction coefficient of different ironmaking raw materials can be stored in the system in advance, wherein the storage correction coefficient can be a correction coefficient of the storage amount deviation caused by different skin return modes, and the consumption index correction coefficient can be a coefficient for adjusting the consumption index to balance the balance of income and expenditure when the skin return mode is different.

[0041] S103, calculating the second storage amount of the ironmaking raw material in the second skin return mode based on the first storage amount, the train freight ratio, and the storage correction coefficient.

[0042] Specifically, the first storage amount, the train freight ratio, and the storage correction coefficient can be substituted into the storage amount calculation formula of the second skin return mode to calculate the second storage amount. After calculating the second storage amount, the ironmaking raw material is stored in the system account with the second storage amount when switching to the second skin return mode.

[0043] For example, if the second skin return mode is marked skin return mode, the first storage amount, the train freight ratio, and the storage correction coefficient can be substituted into the first formula to calculate the second storage amount, and the second storage amount calculated by the first formula is less than the first storage amount; if the second skin return mode is full skin return mode, the first storage amount, the train freight ratio, and the storage correction coefficient can be substituted into the second formula to calculate the second storage amount, and the second storage amount calculated by the first formula is greater than the first storage amount.

[0044] S104, correcting the first consumption index based on the train freight ratio and the consumption index correction coefficient to obtain the second consumption index in the second skin return mode.

[0045] For example, if the second skin return mode is marked skin return mode, the first consumption index can be reduced by the train freight ratio and the consumption index correction coefficient, and the obtained second consumption index is less than the first consumption index; if the second skin return mode is full skin return mode, the first consumption index can be increased by the train freight ratio and the consumption index correction coefficient, and the obtained second consumption index is greater than the first consumption index.

[0046] The embodiment of the present application determines the first return skin mode of the ironmaking raw material and the ironmaking raw material data including the first storage quantity, the train freight ratio and the first consumption index, and when the instruction of switching from the first return skin mode to the second return skin mode is received, the storage correction coefficient and the consumption index correction coefficient of the ironmaking raw material are obtained, the second storage quantity under the second return skin mode is calculated through the first storage quantity, the train freight ratio and the storage correction coefficient, and the second consumption index under the second return skin mode is obtained by correcting the first consumption index based on the train freight ratio and the consumption index correction coefficient, so that the storage quantity and the consumption index are adjusted when the return skin mode is switched, the consumption index and the storage quantity are adapted to the corresponding return skin mode, the finished product, the consumption index and the storage quantity are adapted to the inventory check, the inventory surplus or inventory loss phenomenon is avoided, and the balance of income and expenditure is achieved.

[0047] Embodiment two

[0048] Figure 2 A flowchart of the ironmaking raw material return skin mode switching method provided by the second embodiment of the present application is shown in the figure, and the second embodiment of the present application is optimized on the basis of the first embodiment, as shown in the figure, the ironmaking raw material return skin mode switching method includes: Figure 2

[0049] S201, determine the first return skin mode of the ironmaking raw material and the ironmaking raw material data, and the ironmaking raw material data includes the first storage quantity, the train freight ratio and the first consumption index.

[0050] Specifically, the first storage quantity A can be the storage quantity calculated by the ironmaking raw material in the first return skin mode, the first consumption index can be the consumption index set in the first return skin mode, and the train freight ratio Rate can be the proportion of train transportation of the ironmaking raw material set when the ironmaking raw material is purchased.

[0051] S202, when the instruction of switching from the first return skin mode to the second return skin mode is received, the storage correction coefficient and the consumption index correction coefficient of the ironmaking raw material are obtained.

[0052] In this embodiment, the storage correction coefficient and the consumption index correction coefficient can be pre-configured for various ironmaking raw materials, and the configured storage correction coefficient and consumption index correction coefficient are stored in the system, so that the pre-configured storage correction coefficient and consumption index correction coefficient are read when the system receives the return skin mode switching instruction.

[0053] ​The embodiment can be determined by statistical analysis of historical purchase data of various ironmaking raw materials. Specifically, the historical purchase data of the ironmaking raw materials in a preset period is obtained according to a preset period, the historical purchase data includes total net weight of the ironmaking raw materials, number of train freight cars, total net weight of the train freight ironmaking raw materials, actual total tare weight, and finished product yield of the train freight ironmaking raw materials, and the total net weight of the ironmaking raw materials, the number of train freight cars, the total net weight of the train freight ironmaking raw materials, the actual tare weight, and the finished product yield of the train freight ironmaking raw materials are used to calculate the warehouse correction coefficient and the consumption index correction coefficient.

[0054] The embodiment takes iron ore, coking coal, and injection coal as examples, analyzes the historical purchase data of the iron ore, coking coal, and injection coal transported by train into the factory for three consecutive years, and the specific data is shown in Table 1. In the three years, the total number of train cars of the iron ore, coking coal, and injection coal transported into the factory is more than 430,000, the average standard tare weight of the train cars is 23.2 tons, the actual tare weight is 22 tons, and the average tare weight difference is 1.2 tons.

[0055] Table 1:

[0056]

[0057] In Table 1, the standard total tare weight is the product of the number of train freight cars (number of cars into the factory) and the standard tare weight of a single car, the actual total tare weight is the cumulative value of the tare weight of the car in the actual tare return, and the total tare weight difference is the difference between the standard total tare weight and the actual total tare weight.

[0058] After calculating the total tare weight difference of the iron ore, coking coal, and injection coal in three years, the total net weight of the iron ore, coking coal, and injection coal according to the actual tare return (total net weight of the train freight ironmaking raw materials) is further obtained, the ratio of the total tare weight difference to the total net weight of the train freight ironmaking raw materials is calculated to obtain the warehouse correction coefficient, and the specific data is shown in Table 2.

[0059] Table 2:

[0060] Material category Total net weight of train freight Standard total tare weight Actual total tare weight Total tare weight difference Warehouse weight deviation rate Iron ore 16942278 5984539 5673729 310810 1.83％ Coking coal 9714056 3449444 3272081 177363 1.83％ Injection coal 1991702 719265 681722 37543 1.88％ Total 28648036 10153248 9627532 525716 1.84％

[0061] Taking the iron ore in Table 2 as an example, the total net weight of the train freight in three years is 16,942,278 tons, the total tare weight difference is 310,810 tons, and the warehouse weight deviation rate is the warehouse correction coefficient

[0062] F = 310,810 / 16,942,278 = 1.83%, and the warehouse correction coefficients of the coking coal and the injection coal can be calculated in the same way, which are 1.83% and 1.88%, respectively.

[0063] Because the amount of original historical purchase data is large enough, the data acquisition time span is long enough (up to three years), and the data analysis results are objective and representative.

[0064] For the consumption index correction coefficient, the train historical freight ratio can be calculated by the first ratio of the total net weight of train freight ironmaking raw materials to the total net weight of ironmaking raw materials, the initial consumption index correction coefficient can be obtained by the second ratio of the product output to the total net weight of train freight ironmaking raw materials, and the target consumption index correction coefficient can be obtained by the third ratio of the initial consumption index correction coefficient to the train historical freight ratio.

[0065] Specifically, the train freight into the plant ratios of iron ore, coking coal and injection coal in the past three years are shown in Table 3 as follows:

[0066] Table 3:

[0067]

[0068] In the above Table 3, taking iron ore as an example, the total amount into the plant is the total amount of train and automobile freight into the plant (the total net weight of ironmaking raw materials into the plant in the past three years), the train freight ratio of iron ore is

[0069] Rate = 16942278 / 29480212 = 57.47%, and similarly, the train freight ratios of coking coal and injection coal are 80.77% and 62.98% respectively.

[0070] The influence of the total tare weight difference on the consumption of iron ore, coking coal and injection coal is determined, and is shown in Table 4 as follows:

[0071] Table 4:

[0072]

[0073] In the above Table 4, the iron output is the product output with iron ore and injection coal as ironmaking raw materials (including the freight amount of train and automobile), and the coke output is the product output with coking coal as ironmaking raw materials. Therefore, the initial consumption index correction coefficient of iron ore can be calculated as 310810 / 17919666 = 17.34 kg / t, that is, 17.34 kg of iron ore needs to be adjusted for every ton of product iron produced when the return skin mode is switched, so as to balance the quantity change of storage with different storage amounts after the return skin mode is switched, and achieve the balance of income and expenditure. Similarly, the initial consumption index correction coefficient of coking coal can be calculated as 177363 / 8063624 = 22.00 kg / t, and the initial consumption index correction coefficient of injection coal can be calculated as 37543 / 17919666 = 2.1 kg / t.

[0074] The above table 4 is the consumption index correction coefficient when the proportion of train freight of iron ore, coking coal and injection coal is 57.47%, 80.77% and 62.98% respectively. Different train freight proportions are different. Through research and analysis, when the standard skin / real skin switching is carried out, the higher the proportion of train freight, the greater the influence on the inventory quantity, and the greater the influence on the consumption, that is, the proportion of train freight is proportional to the influence of ironmaking raw materials on inventory and consumption.

[0075] For the consumption index correction coefficient, the ratio of the initial consumption index correction coefficient to the proportion of train freight can be calculated to obtain the consumption correction coefficient of each percentage of the proportion of train freight. The specific is shown in table 5:

[0076] Table 5:

[0077]

[0078]

[0079] In the above table 5, from table 3 and table 4, when the proportion of train freight of iron ore is 57.47%, the ore consumption is 17.34kg / t. Since the proportion of train freight is proportional to the influence of ironmaking raw materials on inventory and consumption, the change rate of ore consumption can be calculated when the proportion of train freight changes by 1%: 17.34 / 57.47=0.30kg / t. Similarly, the change rate of coal consumption and injection coal ratio can be calculated when the proportion of train freight changes by 1%: 0.27kg / t, 0.03kg / t, that is, the final consumption index correction coefficients of iron ore, coking coal and injection coal are 0.30kg / t, 0.27kg / t and 0.03kg / t respectively.

[0080] S203, if the second skin return mode is standard skin return, the second inventory quantity of ironmaking raw materials in the second skin return mode is calculated by the first formula.

[0081] When the ironmaking raw materials are stored, if the first skin return mode is real skin return and the second skin return mode is standard skin return, the second inventory quantity B of ironmaking raw materials in the second skin return mode can be calculated by the following first formula:

[0082] B=A×(1-F×Rate);

[0083] A is the first storage quantity, Rate is the train freight ratio, F is the storage correction coefficient, for example, assuming that the storage quantity of iron ore calculated when real skin is returned is A = 10000t, the train freight ratio Rate = 50%, the storage correction coefficient F = 1.83%, when switching to the standard skin return mode, the second storage quantity B = 10000*(1-1.83*50%) = 9908.5t, which meets the condition that the storage quantity when the standard skin return is less than the storage quantity when the real skin return, avoiding the problem that the storage quantity on the account is high after switching to the real skin return and still calculating the storage quantity according to the real skin return.

[0084] S204, if the second return mode is standard skin return, the second storage quantity of the iron-making raw material in the second return mode is calculated by the second formula.

[0085] When the iron-making raw material is stored, if the first return mode is standard skin return and the second return mode is real skin return, the second storage quantity B of the iron-making raw material in the second return mode can be calculated by the following second formula:

[0086] B = A / (1-F*Rate);

[0087] A is the first storage quantity, Rate is the train freight ratio, F is the storage correction coefficient, for example, assuming that the storage quantity of iron ore calculated when real skin is returned is A = 10000t, the train freight ratio Rate = 50%, the storage correction coefficient F = 1.83%, when switching to the standard skin return mode, the second storage quantity B = 10000 / (1-1.83*50%) = 10092t, which meets the condition that the storage quantity when the standard skin return is less than the storage quantity when the real skin return, avoiding the problem that the storage quantity on the account is high after switching to the real skin return and still calculating the storage quantity according to the real skin return.

[0088] S205, the product of the train freight ratio and the consumption index correction coefficient is calculated to obtain the unit output index adjustment amount.

[0089] The consumption index correction coefficient refers to the consumption adjustment amount of the iron-making raw material per percentage, and the product of the train freight ratio of the iron-making raw material and the consumption index correction coefficient can be calculated, that is, the unit output index adjustment amount of the iron-making raw material this time, that is, the consumption index adjustment amount of the iron-making raw material per ton of product produced.

[0090] Taking iron ore as an example, the consumption correction coefficient of iron ore per percentage is 0.30kg / t, that is, the consumption of iron ore per ton of iron produced through iron ore increases or decreases by 0.3kg when the proportion of iron ore transported by train increases by 1%, for example, the train freight ratio of the iron-making raw material is 80%, and the unit output index adjustment amount of the iron ore is 80*0.30kg / t = 24kg / t.

[0091] S206, if the second skin return mode is the standard skin return mode, a difference between the first consumption index and the unit production index adjustment amount is calculated to obtain a second consumption index in the second skin return mode.

[0092] Specifically, if the first skin return mode is the full skin return mode and the second skin return mode is the standard skin return mode, since the storage amount of the standard skin return mode is less than that of the full skin return mode, after switching to the standard skin return mode, the second consumption index of the standard skin return mode should be less than the first consumption index of the full skin return mode. Specifically, a difference between the current first consumption index (the consumption index in the full skin return mode) and the unit production index adjustment amount is calculated to obtain the second consumption index in the second skin return mode (the consumption index in the standard skin return mode), so that after the second storage amount of the ironmaking raw material in the system account is reduced after switching to the standard skin return mode, the second consumption index is also reduced, and the product of the finished product and the second consumption index is equal to the second storage amount when calculated, achieving a balance between income and expenditure.

[0093] S207, if the second skin return mode is the full skin return mode, a sum of the first consumption index and the unit production index adjustment amount is calculated to obtain a second consumption index in the second skin return mode.

[0094] Specifically, if the first skin return mode is the standard skin return mode and the second skin return mode is the full skin return mode, since the storage amount of the full skin return mode is greater than that of the standard skin return mode, after switching to the full skin return mode, the second consumption index of the full skin return mode should be greater than the first consumption index of the standard skin return mode. Specifically, a sum of the current first consumption index (the consumption index in the standard skin return mode) and the unit production index adjustment amount is calculated to obtain the second consumption index in the second skin return mode (the consumption index in the full skin return mode), so that after the second storage amount of the ironmaking raw material in the system account is increased after switching to the full skin return mode, the second consumption index is also improved, and the product of the finished product and the second consumption index is equal to the second storage amount when calculated, achieving a balance between income and expenditure.

[0095] S208, a storage amount deviation of the ironmaking raw material is calculated based on the first storage amount and the second storage amount.

[0096] Specifically, a difference between the first storage amount and the second storage amount can be calculated as the storage amount deviation of the ironmaking raw material.

[0097] S209, a reference price of the ironmaking raw material is determined based on the storage amount deviation.

[0098] Specifically, if the first return skin mode is real skin return and the second return skin mode is marked skin return, the second storage quantity is less than the first storage quantity, and the second storage quantity is less than the true net weight of the iron-making raw material, the iron-making raw material supplier will appear a loss ton. In order to make up for the loss of the supplier, the purchase price of the iron-making raw material can be increased. Specifically, the increase range of the purchase price can be calculated according to the storage quantity deviation. The increase range is proportional to the storage quantity deviation. Specifically, the second purchase price of the second return skin mode (marked skin) can be obtained by calculating the sum of the first purchase price of the first return skin mode (real skin) and the increase range, and the reference price is obtained.

[0099] Similarly, if the first return skin mode is marked skin return and the second return skin mode is real skin return, the second storage quantity is greater than the first storage quantity, and the second storage quantity is equal to the true net weight of the iron-making raw material. If the iron-making raw material continues to be purchased at the purchase price of the first return skin mode, the steel enterprise will appear a loss. The decrease range of the purchase price can be calculated according to the storage quantity deviation. The decrease range is proportional to the storage quantity deviation. Specifically, the second purchase price of the second return skin mode (real skin) can be obtained by calculating the difference between the first purchase price of the first return skin mode (marked skin) and the decrease range, and the reference price is obtained.

[0100] S210, generate consumption index adjustment prompt information and purchase price adjustment prompt information.

[0101] After correcting the consumption index and calculating the reference price, a prompt message including the corrected consumption index and the reference price can be generated to prompt the system to modify the purchase price and the consumption index, so that the consumption index, the finished product yield and the storage quantity on the account are matched during the inventory to achieve the balance of income and expenditure.

[0102] In order to make the person skilled in the art more request to understand the iron-making raw material return skin mode switching method of the present application, the balance of income and expenditure after the return skin mode switching is explained as follows:

[0103] Taking iron ore as an example, if 10000 tons of iron ore are purchased for the first time, the iron ore supplier delivers 10000 tons of iron ore by train, and the steel enterprise stores the iron ore according to the real skin return mode. The system account actually stores 10000 tons, and 4000 tons of molten iron are output and stored. The iron ore consumption index is 10000 / 4000 = 2.5, that is, 2.5 tons of iron ore are consumed for every ton of finished product iron.

[0104] If 10,000 tons of iron ore is purchased for the second time, the iron ore supplier delivers 10,000 tons of iron ore by train freight, the steel enterprise switches to the standard skin back to the skin storage, the system actually stores 9,000 tons on the account, since the actual iron ore is still 10,000 tons, 4,000 tons of molten iron is actually produced after 10,000 tons of iron ore is consumed, if the iron ore consumption index in the system is still 2.5, the calculated consumed iron ore is 4,000*2.5=10,000 tons, but actually only 9,000 tons is stored in the system account, which is inconsistent with the account, and the balance cannot be balanced during the inventory, after the scheme of the embodiment of the application is used, the iron ore consumption index is adjusted to 2.25, that is, 2.5 tons of iron ore is consumed for producing 1 ton of finished product iron, the iron ore consumption index 2.25 is reduced compared to 2.5 when the real skin back to the skin is used, the calculated consumed iron ore is 4,000*2.25=9,000 tons, which is consistent with the actual 9,000 tons stored in the system account, and the balance is achieved.

[0105] When the instruction of switching from the first skin back mode to the second skin back mode is received, the embodiment of the application acquires the storage correction coefficient and the consumption index correction coefficient of the iron-making raw material, calculates the second storage amount in the second skin back mode through the first storage amount, the train freight ratio and the storage correction coefficient, and modifies the first consumption index based on the train freight ratio and the consumption index correction coefficient to obtain the second consumption index in the second skin back mode, which realizes the adjustment of the storage amount and the consumption index when the skin back mode is switched, so that the consumption index and the storage amount are adapted to the corresponding skin back mode, the finished product, the consumption index and the storage amount are adapted during the inventory, the phenomenon of inventory surplus or inventory loss is avoided, and the balance is achieved.

[0106] Further, the storage amount deviation of the iron-making raw material is calculated based on the first storage amount and the second storage amount, the reference price of the iron-making raw material is determined based on the storage amount deviation, the consumption index adjustment prompt information and the purchase price adjustment prompt information are generated, which realizes the provision of the reference purchase price for different skin back modes, and the loss of the supplier in weight can be balanced by increasing the purchase price when the actual storage amount is small after the real skin is switched to the standard skin back.
