Description

Technical Field

[0001] The present invention relates to the field of data processing technology, and in particular to a method, device, electronic equipment and storage medium for switching an ironmaking raw material peeling mode. Background Art

[0002] Iron ore, coking coal, PCI coal and other ironmaking raw materials are usually transported to steel mills by train and truck due to their large consumption. If they are transported by train, the gross weight is measured when entering the factory, and the tare weight (train car weight) is deducted from the tare weight when leaving the factory. The net weight of the ironmaking raw materials is the difference between the gross weight and the tare weight.

[0003] Tare weight is divided into real tare weight and nominal tare weight. Real tare weight refers to the actual weighed tare weight, while nominal tare weight refers to the nominal tare weight (designed tare weight of the carriage). However, with the wear and aging of the train over a long period of time, the real tare weight is usually smaller than the nominal tare weight. For a carriage's iron-making raw materials, if the net weight is calculated using the real tare weight as the tare weight, the net weight will be smaller. Enterprises switch between the real tare weight and the nominal tare weight according to the needs of production and operation, as the net weight of iron-making raw materials calculated in the two modes is different.

[0004] After the return mode is switched, if the consumption index of ironmaking raw materials is not adjusted, there will be surplus or shortage in the physical inventory. The existing technology usually adjusts the consumption index of ironmaking raw materials to achieve a balance between income and expenditure through the profit and loss tons of the inventory after the surplus or shortage occurs. However, it is difficult to accurately determine the profit and loss tons of ironmaking raw materials by inventory. Therefore, how to adjust the storage quantity and consumption index of ironmaking raw materials after the return mode is switched to achieve a balance between income and expenditure has become a technical problem that needs to be solved urgently.

[0030] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0031] Steel companies usually use trains to transport iron-making raw materials into the factory due to their large demand for iron ore, coking coal, pulverized coal and other iron-making raw materials. 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 wagon, and the tare weight is the weight of the wagon. In actual applications, according to the needs of production and operation, the tare weight is sometimes measured by standard tare (standard tare weight designed for the carriage) and sometimes by actual tare (actual tare weight of the carriage). After the carriage is worn and aged for a long time, the actual tare is usually smaller than the standard tare. If the net weight of the iron-making raw materials is calculated according to the actual tare, the net weight of the iron-making raw materials is equal to the actual weight. If the net weight is calculated according to the standard tare, the net weight is less than the actual weight.

[0032] For example, if a train of multiple cars of iron ore is purchased, the total gross weight of the train freight entering the factory is 10,000 tons. If the net weight of the iron ore is calculated according to the actual skin, it is 9,000 tons, and it is put into storage in the system at a net weight of 9,000 tons. If the net weight of the iron ore is calculated according to the standard skin, it may be 8,000 tons, and it is put into storage in the system at a net weight of 8,000 tons. However, in fact, the net weight of multiple cars of iron ore in a train is objectively the same, that is, the actual substance of the iron ore may be close to 9,000 tons. That is, no matter whether the iron ore is put into storage according to the actual skin or the standard skin, the weight of the finished iron that can be refined after the iron ore in the warehouse is consumed is the same. Assuming that the iron product is 3,000 tons, and assuming that the consumption index of the actual skin (the iron ore consumed for each ton of iron refined) is C1=9000 / 3000=3, when switching to When the standard skin is used, 8,000 tons of iron ore are put into storage. If the consumption is still calculated according to C1, 9,000 tons of iron ore will be consumed for 3,000 tons of iron products, but only 8,000 tons of iron ore are put into storage in the system, and the data of storage and outbound delivery cannot reach a balance between income and expenditure. In another case, assuming that the current consumption index C2 is calculated according to the standard skin, which is C2=8000 / 3000≈2.67, when switching to the actual skin, if the consumption is still calculated according to C2, 8,000 tons of iron ore will be consumed for 3,000 tons of finished iron, but 9,000 tons of iron ore are put into storage in the system. In theory, there will be 1,000 tons of iron ore left in the warehouse, but in fact it has been consumed, resulting in surplus and deficit in physical inventory, which cannot achieve a balance between income and expenditure, and for iron ore suppliers, there will be losses if the net weight is calculated according to the standard skin.

[0033] In order to solve the problems caused by switching between the above-mentioned different peeling modes, the present invention provides a method for switching the peeling mode of ironmaking raw materials in the following embodiment, so as to accurately calculate the storage quantity of ironmaking raw materials and accurately adjust the ironmaking raw material consumption index when the peeling mode is switched, so as to achieve a balance between income and expenditure.

[0034] Embodiment 1

[0035] Figure 1 This is a flow chart of a method for switching the peeling mode of ironmaking raw materials provided in the first embodiment of the present invention. This embodiment is applicable to the case of switching the peeling mode of ironmaking raw materials. The method can be executed by a switching device for switching the peeling mode of ironmaking raw materials. The switching device for switching the peeling mode of ironmaking raw materials can be implemented in the form of hardware and / or software and can be configured in an electronic device. Figure 1 As shown, the method for switching the ironmaking raw material peeling mode includes:

[0036] S101, determining a first return mode and raw material data of ironmaking raw materials to be stored, wherein the raw material data includes a first storage quantity, a train freight ratio and a first consumption index.

[0037] In this embodiment, the ironmaking raw materials may be iron ore, coking coal, pulverized coal and other ironmaking raw materials required by steel enterprises. The first return mode may be the current return mode of the ironmaking raw materials that have been put into storage. The raw material data may include the first storage quantity, the train freight ratio and the first consumption index, wherein the first storage quantity may refer to the net weight of the ironmaking raw materials calculated by the first return mode, the first consumption index may be the consumption index of the ironmaking raw materials under the first return mode, the consumption index may be the weight of the ironmaking raw materials consumed to produce unit weight of finished products, the ironmaking raw materials may be transported by train and car at the same time, and the train freight ratio may refer to 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 train and car transportation).

[0038] In one embodiment, when placing an order for ironmaking raw materials, a transportation mode is usually set, such as setting the train freight ratio, the automobile freight ratio, and the purchase quantity, etc. When the ironmaking raw materials are transported to the factory via train carriages, the gross weight is weighed, and then the total net weight of the ironmaking raw materials is calculated according to the net weight calculation method of the first return mode as the first inventory quantity.

[0039] S102. When receiving an instruction to switch from the first peeling mode to the second peeling mode, obtaining a storage correction coefficient and a consumption index correction coefficient of ironmaking raw materials.

[0040] In this embodiment, if the first return mode is real return mode, the second return mode is standard return mode, and if the first return mode is standard return mode, the second return mode is real return mode. When the return mode switching instruction is received, the storage correction coefficient and consumption index correction coefficient of the ironmaking raw materials can be obtained. Specifically, the storage correction coefficients and consumption index correction coefficients of different ironmaking raw materials can be pre-stored in the system, wherein the storage correction coefficient can be a correction coefficient for the storage quantity deviation caused by different return modes, and the consumption index correction coefficient can be a coefficient for adjusting the consumption index in order to balance the income and expenditure due to different return modes.

[0041] S103, calculating the second incoming quantity of the ironmaking raw materials in the second return mode based on the first incoming quantity, the train freight ratio and the incoming correction coefficient.

[0042] Specifically, the first warehouse quantity, the train freight ratio and the warehouse correction coefficient can be substituted into the warehouse quantity calculation formula of the second return mode to calculate the second warehouse quantity. After calculating the second warehouse quantity, when switching to the second return mode, the ironmaking raw materials are warehoused with the second warehouse quantity on the system account.

[0043] Exemplarily, if the second return mode is the standard return mode, the first warehouse quantity, the train freight ratio and the warehouse correction coefficient can be substituted into the first formula to calculate the second warehouse quantity, and the second warehouse quantity calculated by the first formula is less than the first warehouse quantity; if the second return mode is the real return mode, the first warehouse quantity, the train freight ratio and the warehouse correction coefficient can be substituted into the second formula to calculate the second warehouse quantity, and the second warehouse quantity calculated by the first formula is greater than the first warehouse quantity.

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

[0045] Exemplarily, if the second return mode is the standard return mode, the first consumption index can be reduced by the train freight ratio and the consumption index correction coefficient, and the second consumption index obtained is smaller than the first consumption index; if the second return mode is the real return mode, the first consumption index can be increased by the train freight ratio and the consumption index correction coefficient, and the second consumption index obtained is larger than the first consumption index.

[0046] After determining the first return mode of ironmaking raw materials and the ironmaking raw material data including the first incoming quantity, the train freight ratio and the first consumption index, the embodiment of the present invention obtains the incoming correction coefficient and the consumption index correction coefficient of the ironmaking raw materials when receiving the instruction to switch from the first return mode to the second return mode, calculates the second incoming quantity under the second return mode through the first incoming quantity, the train freight ratio and the incoming correction coefficient, and corrects the first consumption index based on the train freight ratio and the consumption index correction coefficient to obtain the second consumption index under the second return mode, thereby adjusting the incoming quantity and the consumption index when the return mode is switched, so that the consumption index and the incoming quantity are matched with the corresponding return mode, and the finished products, consumption indicators and the incoming quantity are matched with the inventory during inventory, thereby avoiding the phenomenon of inventory surplus and shortage and achieving a balance between income and expenditure.

[0047] Embodiment 2

[0048] Figure 2 A flow chart of a method for switching the ironmaking raw material peeling mode provided in the second embodiment of the present invention is provided. The embodiment of the present invention is optimized on the basis of the above-mentioned first embodiment. Figure 2 As shown, the method for switching the ironmaking raw material peeling mode includes:

[0049] S201. Determine a first return pattern of ironmaking raw materials and ironmaking raw material data, wherein the ironmaking raw material data includes a first storage quantity, a train freight ratio, and a first consumption index.

[0050] Specifically, the first inventory quantity A can be the inventory quantity calculated for ironmaking raw materials in the first return mode, the first consumption index can be the consumption index set in the first return mode, and the train freight ratio Rate can be the ratio of ironmaking raw materials transported by train set when purchasing ironmaking raw materials.

[0051] S202. When receiving an instruction to switch from the first peeling mode to the second peeling mode, obtaining a storage correction coefficient and a consumption index correction coefficient of the ironmaking raw materials.

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

[0053] This embodiment can be determined through statistical analysis of historical purchasing data of various ironmaking raw materials. Specifically, the historical purchasing data of ironmaking raw materials within a preset time period is obtained according to a preset cycle. The historical purchasing data includes the total net weight of ironmaking raw materials, the number of train freight cars, the total net weight of ironmaking raw materials transported by train, the actual total tare weight and the output of finished products of ironmaking raw materials by train freight. The total net weight of ironmaking raw materials, the number of train freight cars, the total net weight of ironmaking raw materials transported by train, the actual total tare weight and the output of finished products of ironmaking raw materials by train freight are used to calculate the warehousing correction coefficient and the consumption index correction coefficient.

[0054] This embodiment takes iron ore, coking coal and pulverized coal as examples of ironmaking raw materials, and studies and analyzes the historical procurement data of iron ore, coking coal and pulverized coal transported into the factory by train (railway transportation) for three consecutive years. As shown in Table 1 below, the total number of iron ore, coking coal and pulverized coal entering the factory by train in the past three years was more than 430,000. The average standard tare weight of train carriages was 23.2 tons, the actual tare weight was 22 tons, and the average tare weight difference was 1.2 tons.

[0055] Table 1:

[0056]

[0057] In the above Table 1, the standard total tare weight is the product of the number of train freight cars (the number of cars entering the factory) and the standard tare weight of a single carriage, the actual total tare weight is the cumulative value of the tare weight of the carriages weighed when the actual tare weight is returned, 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 iron ore, coking coal and PCI coal in the past three years, the total net weight of iron ore, coking coal and PCI coal according to the actual skin and skin return (the total net weight of ironmaking raw materials transported by train) is further obtained, and the ratio of the total tare weight difference to the total net weight of ironmaking raw materials transported by train is calculated to obtain the warehousing correction coefficient, as shown in Table 2 below:

[0059] Table 2:

[0060] Material Category Total net weight of train freight Standard total tare weight Actual total tare weight Total tare difference Incoming weight deviation rate iron ore 16942278 5984539 5673729 310810 1.83％ Coking coal 9714056 3449444 3272081 177363 1.83％ PCI 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 train freight in three years is 16942278t, and the total tare difference is 310810t. The warehouse weight deviation rate is the warehouse correction coefficient.

[0062] F=310810 / 16942278=1.83%. Similarly, it can be calculated that the storage correction coefficients of coking coal and pulverized coal are 1.83% and 1.88% respectively.

[0063] Since the amount of original historical procurement data is large enough and the time span for data collection is long enough (up to 3 years), the data analysis results are objective and representative.

[0064] For the consumption index correction coefficient, we can first calculate the first ratio of the total net weight of ironmaking raw materials in train freight to the total net weight of ironmaking raw materials to obtain the historical train freight ratio, calculate the second ratio of the finished product output to the total net weight of ironmaking raw materials in train freight to obtain the initial consumption index correction coefficient, and calculate the third ratio of the initial consumption index correction coefficient to the historical train freight ratio to obtain the target consumption index correction coefficient.

[0065] Specifically, the proportion of iron ore, coking coal and PCI train freight entering the factory in the past three years is shown in Table 3:

[0066] Table 3:

[0067]

[0068] In Table 3 above, iron ore is used as an example. The total incoming volume is the total volume of train and truck freight entering the factory (the total net weight of ironmaking raw materials entering the factory in three years). The proportion of train freight for iron ore is

[0069] Rate = 16942278 / 29480212 = 57.47%. Similarly, it can be calculated that the railway freight ratios of coking coal and PCI coal are 80.77% and 62.98% respectively.

[0070] The effect of the total tare difference on the consumption of iron ore, coking coal and PCI coal is determined as shown in Table 4 below:

[0071] Table 4:

[0072]

[0073] In the above Table 4, the iron output is the finished product output with iron ore and pulverized coal as iron-making raw materials (including freight volume of trains and cars), and the total coke output is the finished product output with coking coal as iron-making raw materials. From this, the initial consumption index correction coefficient of iron ore can be calculated: 310810 / 17919666=17.34kg / t, that is, the iron ore consumed for each ton of finished iron produced when the skin-returning mode is switched needs to be adjusted by 17.34kg to balance the change in quantity of different storage amounts after the skin-returning mode is switched, so as to achieve a balance between income and expenditure. Similarly, the initial consumption index correction coefficient of coking coal can be calculated: 177363 / 8063624=22.00kg / t, and the initial consumption index correction coefficient of pulverized coal can be calculated: 37543 / 17919666=2.1kg / t.

[0074] Table 4 above shows the consumption index correction coefficients when the train freight ratios of iron ore, coking coal and pulverized coal are 57.47%, 80.77% and 62.98% respectively. Different train freight ratios are different. After research and analysis, when switching between standard skin / real skin, the higher the train freight ratio, the greater the impact on the inventory book quantity, and then the greater the impact on consumption, that is, the impact of the train freight ratio on the warehousing and consumption of ironmaking raw materials is directly proportional.

[0075] For the consumption index correction coefficient, the ratio of the initial consumption index correction coefficient to the train freight ratio can be calculated to obtain the consumption correction coefficient for each percentage of the train freight ratio, as shown in Table 5:

[0076] Table 5:

[0077]

[0078]

[0079] In the above Table 5, it can be seen from Table 3 and Table 4 that when the railway freight ratio of iron ore is 57.47%, the ore consumption is 17.34kg / t. Since the railway freight ratio has a positive proportional relationship with the storage and consumption of ironmaking raw materials, the ore consumption change rate when the railway freight ratio changes by 1% can be calculated: 17.34 / 57.47=0.30kg / t. Similarly, the coal consumption and coal injection ratio when the railway freight ratio changes by 1% can be calculated to be 0.27kg / t and 0.03kg / t, respectively. That is, the final consumption index correction coefficients of iron ore, coking coal and pulverized coal are 0.30kg / t, 0.27kg / t and 0.03kg / t, respectively.

[0080] S203: If the second return mode is standard return mode, the second storage quantity of the ironmaking raw materials in the second return mode is calculated by the first formula.

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

[0082] B = A × (1-F × Rate);

[0083] A is the first warehouse quantity, Rate is the train freight ratio, and F is the warehouse correction coefficient. For example, assuming that the iron ore warehouse quantity calculated at the time of actual skin return is A=10000t, the train freight ratio Rate=50%, the warehouse correction coefficient F=1.83%, when switching to the standard skin return mode, the second warehouse quantity B=10000×(1-1.83×50%)=9908.5t, which meets the situation that the warehouse quantity at the time of standard skin return is less than the warehouse quantity at the time of actual skin return, avoiding the problem of high warehouse quantity on the books after switching to standard skin return and still calculating the warehouse quantity according to the actual skin return.

[0084] S204: If the second return mode is standard return mode, calculate the second storage quantity of the ironmaking raw materials in the second return mode by using the second formula.

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

[0086] B = A / (1-F×Rate);

[0087] A is the first warehouse quantity, Rate is the train freight ratio, and F is the warehouse correction coefficient. For example, assuming that the iron ore warehouse quantity calculated at the time of actual skin return is A=10000t, the train freight ratio Rate=50%, the warehouse correction coefficient F=1.83%, when switching to the standard skin return mode, the second warehouse quantity B=10000 / (1-1.83×50%)=10092t, which meets the situation that the warehouse quantity at the time of actual skin return is greater than the warehouse quantity at the time of standard skin return, avoiding the problem of low warehouse quantity on the books after switching to actual skin return and still calculating the warehouse quantity according to the standard skin return.

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

[0089] The consumption index correction coefficient refers to the adjustment amount per percentage of ironmaking raw materials consumption. The product of the railway freight ratio of ironmaking raw materials and the consumption index correction coefficient can be calculated to obtain the unit output index adjustment amount of this ironmaking raw materials, that is, the consumption index adjustment amount of ironmaking raw materials for each ton of finished products produced.

[0090] Taking iron ore as an example, the consumption correction factor for each percentage of iron ore is 0.30kg / t, that is, for every 1% increase in the proportion of iron ore transported by rail, the consumption of iron ore for each ton of iron produced by iron ore will increase or decrease by 0.3kg. For example, if the proportion of ironmaking raw materials transported by rail is 80%, the unit output index adjustment of iron ore is 80×0.30kg / t=24kg / t.

[0091] S206: If the second return mode is standard return mode, the difference between the first consumption index and the unit output index adjustment amount is calculated to obtain the second consumption index under the second return mode.

[0092] Specifically, if the first return mode is real skin return, and the second return mode is standard skin return, since the inventory quantity of standard skin return is smaller than that of real skin return, after switching to standard skin return, the second consumption index of standard skin return should be smaller than the first consumption index of real skin return. Specifically, the difference between the current first consumption index (consumption index of real skin return) and the unit output index adjustment amount can be calculated to obtain the second consumption index under the second return mode (consumption index of standard skin return), so that when switching to standard skin return, the second inventory quantity of ironmaking raw materials on the system account becomes smaller, and the second consumption index is also reduced. When calculating the product of the finished product and the second consumption index, it is equal to the second inventory quantity, so as to achieve a balance between income and expenditure.

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

[0094] Specifically, if the first return mode is standard return mode and the second return mode is real return mode, since the inventory volume of real return is greater than that of standard return, after switching to real return, the second consumption index of real return should be greater than the first consumption index when the standard return is applied. Specifically, the sum of the current first consumption index (the consumption index when the standard return is applied) and the unit output index adjustment amount can be calculated to obtain the second consumption index under the second return mode (the consumption index when the real return is applied), so that when the second inventory volume of the system account of ironmaking raw materials increases when switching to real return, the second consumption index also increases, and the product of the finished product and the second consumption index is equal to the second inventory volume, thereby achieving a balance between income and expenditure.

[0095] S208. Calculate the storage quantity deviation of the ironmaking raw materials based on the first storage quantity and the second storage quantity.

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

[0097] S209. Determine the reference price of ironmaking raw materials based on the inventory quantity deviation.

[0098] Specifically, if the first return mode is real skin return, and the second return mode is standard skin return, the second warehousing quantity is less than the first warehousing quantity, and the second warehousing quantity is less than the actual net weight of the ironmaking raw materials, the ironmaking raw material supplier will suffer a loss of tons. In order to make up for the supplier's loss, the purchase price of the ironmaking raw materials can be increased. Specifically, the increase in the purchase price can be calculated based on the warehousing quantity deviation, and the increase in the purchase price is proportional to the warehousing quantity deviation. Specifically, the sum of the first purchase price under the first return mode (real skin) and the increase in the price can be calculated to obtain the purchase price of the second return mode (standard skin) to obtain the reference price.

[0099] Similarly, if the first return mode is standard return mode, and the second return mode is real return mode, the second inventory quantity is greater than the first inventory quantity, and the second inventory quantity is equal to the actual net weight of the iron-making raw materials. If the iron-making raw materials continue to be purchased at the purchase price of the first return mode, the steel enterprise will suffer losses. The price reduction range of the purchase price can be calculated by the inventory quantity deviation, and the price reduction range is proportional to the inventory quantity deviation. Specifically, the difference between the first purchase price under the first return mode (standard purchase price) and the price reduction range can be calculated to obtain the purchase price of the second return mode (real purchase price) to obtain the reference price.

[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 reference price can be generated to prompt the system to modify the purchase price and consumption index so that the consumption index, finished product output and inventory quantity on the books are matched during inventory counting to achieve a balance between income and expenditure.

[0102] In order to enable those skilled in the art to better understand the ironmaking raw material peeling mode switching method of the present invention, the following is an example to illustrate the balance principle after the peeling mode switching:

[0103] Taking iron ore as an example, if 10,000 tons of iron ore are purchased for the first time, the iron ore supplier actually delivers 10,000 tons of iron ore via train freight, and the steel company puts the iron ore into storage according to the real-skin return mode. The system actually puts 10,000 tons into storage on the books, and 4,000 tons of molten iron are put into storage on the books. The iron ore consumption index is 10,000 / 4,000=2.5, that is, 2.5 tons of iron ore are consumed to produce 1 ton of finished iron.

[0104] If 10,000 tons of iron ore is purchased for the second time, the iron ore supplier actually delivers 10,000 tons of iron ore by train freight, and the steel enterprise switches to standard skin return storage. The actual storage in the system account is 9,000 tons. Since the actual iron ore is still 10,000 tons, after consuming 10,000 tons of iron ore, 4,000 tons of molten iron are actually produced. If the iron ore consumption index in the system is still 2.5, the iron ore consumption is calculated to be 4,000×2.5=10,000 tons, but the actual Only 9,000 tons were put into storage on the system account, resulting in a discrepancy between the accounts and the balance of payments during inventory. After adopting the solution of the embodiment of the present invention, the iron ore consumption index is adjusted to 2.25, that is, 2.5 tons of iron ore are required to produce 1 ton of finished iron. The iron ore consumption index of 2.25 is lower than 2.5 during actual skinning. The calculated consumption of iron ore is 4,000×2.25=9,000 tons, which is consistent with the 9,000 tons actually put into storage on the system account, achieving a balance of payments.

[0105] When the embodiment of the present invention receives an instruction to switch from the first return skin mode to the second return skin mode, it obtains the storage correction coefficient and the consumption index correction coefficient of the ironmaking raw materials, calculates the second storage quantity under the second return skin mode through the first storage quantity, the train freight ratio and the storage correction coefficient, and corrects the first consumption index based on the train freight ratio and the consumption index correction coefficient to obtain the second consumption index under the second return skin mode, thereby adjusting the storage quantity and consumption index when the return skin mode is switched, so that the consumption index and the storage quantity are adapted to the corresponding return skin mode, and the finished products, consumption indicators and storage quantity are adapted during inventory, thereby avoiding the phenomenon of inventory surplus and shortage and achieving a balance between income and expenditure.

[0106] Furthermore, the inventory quantity deviation of ironmaking raw materials is calculated based on the first inventory quantity and the second inventory quantity, the reference price of ironmaking raw materials is determined based on the inventory quantity deviation, and consumption index adjustment prompt information and purchase price adjustment prompt information are generated, thereby providing reference purchase prices for different return skin modes. When the actual inventory quantity is small when switching from real skin to standard skin return skin, resulting in supplier losses, the supplier's loss in weight can be balanced by increasing the purchase price.
