[0002] Refined oil refers to petroleum products after processing, refining or extraction. Common refined oils include gasoline, diesel, aviation kerosene, lubricating oil, etc. Refined oil has a wide range of applications in industrial production and daily life and is an indispensable energy product in modern society.

[0003] For large oil companies, the capital occupation brought by refined oil inventory, storage costs and the derivative risks of inventory value caused by price fluctuations are important factors affecting the efficiency of large oil enterprises. Thus, the increase or decrease in inventory value will directly affect the efficiency of the entire enterprise. Due to the many factors affecting the inventory scale and the complex inventory classification, the demands for inventory scale in midstream refining enterprises and downstream sales enterprises in the entire oil supply chain are different, making it extremely difficult to formulate a reasonable and universal inventory calculation method.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer and more understandable, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but not to limit the present invention. It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined arbitrarily with each other.

[0023] To facilitate the understanding of the technical solutions provided in this application, the relevant content of the technical solutions in this application will be described first below.

[0024] Through the research on the current refined oil inventory, it is found that there are the following problems in the calculation of refined oil inventory. (1) The consideration of inventory calculation is insufficient and the direction is single. For example, for the current rapidly changing external environment, the reference value of historical data in the historical inventory method is limited, and there is also unreasonable data pollution; the model established by the business operation method does not consider the non-movable, in-transit, and seasonal reserves of refined oil in oil enterprises, and only focuses on the current turnover, and cannot cope with annual and overall changes; the safety operation method starting from the perspective of safety inventory will lead to problems such as overstocking in the off-season of demand, excessive capital occupation, and poor economy. (2) For the different requirements of sales companies and refining companies for reasonable inventory, the existing technologies do not classify them, nor build a systematic model, and cannot fully meet the requirements of their respective inventory operations.

[0025] The high and low levels and specific capacities of inventory are mainly determined by its carrying functions. To study the inventory level, it is necessary to first study the functions it carries. According to the definition of logistics, inventory plays a buffering, regulating, and balancing role in the production and operation of enterprises, can eliminate the differences in time between the production and consumption of products, enable enterprises to provide services on time and as needed, prevent out-of-stock situations, save expenses, and ensure the smooth progress of production and sales. Usually, according to the functions carried by inventory, inventory is divided into seven categories, namely safety inventory, transportation process inventory (in-transit inventory), backlog inventory, promotional inventory, time utility inventory, turnover inventory, and seasonal inventory.

[0026] Safety stock refers to the buffer stock prepared to prevent uncertain factors. In-transit inventory refers to the inventory in the state of transportation. Overstock inventory refers to the inventory of goods with quality problems, damages, or unsalable due to lack of market. Promotional inventory refers to the inventory established to match the company's promotional activities and increase the overdue sales volume. Time-utility inventory refers to the inventory established to avoid losses caused by rising commodity prices to the enterprise or to gain benefits from rising commodity prices. Cycle inventory refers to the periodic inventory formed by batch production or ordering, mainly considering factors such as inventory costs and ordering costs. Seasonal inventory refers to the inventory established to meet special demands in a certain season.

[0027] Concept of reasonable refined oil inventory: The range of inventory that minimizes capital and physical occupancy without affecting production. When the inventory operation is within the reasonable inventory range, production is stable and the economy is relatively high; when the inventory fluctuates outside the reasonable inventory range, it may affect production or economic benefits.

[0028] Classify refined oil inventory through research and in combination with the theoretical basis of logistics and the production operation of petroleum enterprises; then establish an inventory measurement model based on the functions of each inventory and the inventory characteristics of petroleum enterprises; construct respective inventory measurement models for refining enterprises and sales enterprises based on their demand characteristics to measure their respective reasonable inventories.

[0029] Because there are deficiencies in the existing methods and the classification of oil depot inventory, this application classifies refined oil inventory in more detail based on the theory of logistics and the current situation of petroleum company inventory, and qualitatively defines inventories with different characteristics. At the same time, fully mine the data characteristics, sort out factors such as refined oil inventory, actual turnover, and seasonal changes, and clarify the specific algorithms for each functional inventory in combination with the current operation situation and the actual oil depot container structure. After clarifying the specific algorithms for various inventories, explore the upper and lower limits of reasonable refined oil inventory in combination with the current operation mode and the functional composition of the inventory, and complete the construction of the inventory measurement models for refineries and sales enterprises.

[0030] Figure 1 It is a schematic flowchart of the refined oil inventory measurement method provided by the first embodiment of the present invention. As Figure 1 shown, the refined oil inventory measurement method provided by the embodiment of the present invention includes:

[0031] S101. Obtain the refined oil measurement data of the measurement object, where the refined oil measurement data includes refined oil classification and the measurement data of each type of refined oil;

[0032] Specifically, import the refined oil measurement data of the measurement object. The refined oil measurement data includes refined oil classification and the measurement data of each type of refined oil. Among them, the measurement object includes, but is not limited to, refineries and sales enterprises. The refined oil classification includes, but is not limited to, regular gasoline, ethanol gasoline, diesel, and kerosene, which is set according to actual needs and is not limited in the embodiments of the present invention. The refined oil measurement data is selected according to actual needs and is not limited in the embodiments of the present invention. Among them, the execution subject of the refined oil inventory measurement method provided by the embodiments of the present invention includes, but is not limited to, a computer.

[0033] S102. Obtain the reasonable inventory range of each type of refined oil according to the measurement data of each type of refined oil and the inventory measurement model corresponding to the measurement object; among them, the inventory measurement model corresponding to the measurement object is pre-established based on different inventory types of the measurement object.

[0034] Specifically, for each type of refined oil of the measurement object, input the measurement data of each type of refined oil into the inventory measurement model corresponding to the measurement object, and the reasonable inventory range of each type of refined oil can be output. The reasonable inventory range can include the upper limit of the reasonable inventory and the lower limit of the reasonable inventory. The inventory measurement model corresponding to the measurement object is pre-established, and the inventory measurement model corresponding to the measurement object can be established based on different inventory types of the measurement object.

[0035] It can be understood that according to the upper limit of the reasonable inventory and the lower limit of the reasonable inventory of each type of refined oil of the measurement object, the upper limit of the reasonable inventory and the lower limit of the reasonable inventory of the measurement object can be obtained.

[0036] The refined oil inventory measurement method provided by the embodiments of the present invention can obtain the refined oil measurement data of the measurement object. The refined oil measurement data includes refined oil classification and the measurement data of each type of refined oil. According to the measurement data of each type of refined oil and the inventory measurement model corresponding to the measurement object, the reasonable inventory range of each type of refined oil is obtained. Since the inventory measurement model corresponding to the measurement object is established through different inventory types of the measurement object, the accuracy of determining the reasonable inventory range is improved.

[0037] On the basis of the above embodiments, further, the measurement object is a refinery.

[0038] According to the operation situation of the refinery, the inventory of the refinery includes six functions: bearing the bottom of the tank, turnover, seasonal adjustment, alleviating the contradiction between production and sales, export reserve, and maintenance reserve. Combining the four existing types of inventory in the refinery and the six functions of the refinery inventory, the inventory of the refinery can be subdivided into: bottom inventory, turnover inventory, seasonal inventory, production and sales contradiction inventory, export inventory, and maintenance inventory.

[0039] According to the functional composition of the refinery's inventory, the reasonable upper limit and reasonable lower limit of the refinery's inventory can be expressed as:

[0040] The reasonable lower limit of the refinery's inventory = bottom inventory + working inventory + seasonal inventory

[0041] The reasonable upper limit of the refinery's inventory = reasonable lower limit + export inventory

[0042] Since the refined oil products of the refinery can be divided into multiple types, the reasonable inventory of each type of refined oil product can be measured.

[0043] Combining the current operation mode of the enterprise and the functional composition of the inventory, exploring the reasonable upper and lower limits of the refined oil product inventory through different inventory types is beneficial to improving the accuracy of obtaining the reasonable inventory range.

[0044] Figure 2 It is a schematic flowchart of the refined oil product inventory measurement method provided by the second embodiment of the present invention. As Figure 2 shown, obtaining the reasonable inventory range of each type of refined oil product according to the measurement data of each type of refined oil product and the corresponding inventory measurement model of the refinery includes:

[0045] S201. Obtain the first reasonable lower limit of each type of refined oil product according to the bottom inventory, first working inventory, and first seasonal inventory of each type of refined oil product of the refinery;

[0046] Specifically, for each type of refined oil product of the refinery, the sum of the bottom inventory, first working inventory, and first seasonal inventory of each type of refined oil product can be calculated as the first reasonable lower limit of each type of refined oil product.

[0047] S202. Obtain the first reasonable upper limit of each type of refined oil product according to the first reasonable lower limit of each type of refined oil product and the export inventory of each type of refined oil product.

[0048] Specifically, for each type of refined oil product of the refinery, the sum of the first reasonable lower limit of each type of refined oil product and the export inventory of each type of refined oil product can be calculated as the first reasonable upper limit of each type of refined oil product.

[0049] On the basis of the above embodiments, further, the inventory measurement model corresponding to the refinery includes a bottom inventory measurement sub-model; correspondingly, according to the number of storage tanks corresponding to each type of refined oil product, each storage tank parameter, the liquid level retention height of each storage tank, and the bottom inventory measurement sub-model, the bottom inventory corresponding to each type of refined oil product is obtained.

[0050] Specifically, the inventory measurement model corresponding to the refinery includes a bottom inventory measurement sub-model, which is used to measure the bottom inventory of refined oil. Among them, the bottom inventory of refined oil refers to the part of refined oil located at the bottom of storage tanks (storage tanks) that cannot be pumped out and used due to objective conditions such as process requirements, tank type settings, or production safety considerations.

[0051] Input the number of storage tanks corresponding to each type of refined oil, various storage tank parameters, and the reserved liquid level height of each storage tank into the bottom inventory measurement sub-model, and the bottom inventory corresponding to each type of refined oil can be output. Among them, the measurement data of each type of refined oil includes the number of storage tanks corresponding to each type of refined oil, various storage tank parameters, and the reserved liquid level height of each storage tank.

[0052] For example, if the storage tank is cylindrical, the bottom inventory measurement sub-model is Where C 1 represents the bottom inventory, in ten thousand cubic meters, R i represents the radius of the i-th storage tank, in meters, H represents the reserved liquid level height of the storage tank, in meters, n represents the number of storage tanks, i is a positive integer and i is less than or equal to n, and π represents pi.

[0053] Based on the above embodiments, further, the inventory measurement model corresponding to the refinery includes a first turnover inventory measurement sub-model; correspondingly, according to the daily ground delivery volume of each type of refined oil, the ground delivery reserve days, the single-batch transportation preparation scale and transportation cycle corresponding to various factory transportation methods, and the first turnover inventory measurement sub-model, the first turnover inventory corresponding to each type of refined oil is obtained.

[0054] Specifically, the inventory measurement model corresponding to the refinery includes a first turnover inventory measurement sub-model, which is used to measure the first turnover inventory of refined oil. The first turnover inventory of refined oil refers to the refined oil available for loading and external transfer in the refined oil storage of the refinery, and its scale should ensure the highway ground delivery demand of the refinery and the smooth progress of single-batch operations in ways such as railway, pipeline, and waterway.

[0055] Input the daily ground delivery volume of each type of refined oil, the ground delivery reserve days, the single-batch transportation preparation scale and transportation cycle corresponding to various factory transportation methods into the first turnover inventory measurement sub-model, and the first turnover inventory corresponding to each type of refined oil can be output. Among them, the measurement data of each type of refined oil includes the daily ground delivery volume of each type of refined oil, the ground delivery reserve days, the single-batch transportation preparation scale and transportation cycle corresponding to various factory transportation methods. The types of factory transportation methods include but are not limited to waterway transportation, railway transportation, pipeline transportation, etc., which are set according to actual needs, and are not limited in the embodiments of the present invention.

[0056] For example, the first cycle inventory measurement sub-model includes where C 2 represents the first cycle inventory, in ten thousand cubic meters; E represents the daily ground delivery volume, in ten thousand cubic meters per day; D represents the minimum reserved ground delivery days, in days; S j represents the single-batch transportation stock preparation scale corresponding to the j-th type of factory-out transportation method, in ten thousand cubic meters per cycle; T j represents the transportation cycle, in days; j is a positive integer and j is less than or equal to m, where m represents the types of factory-out transportation methods.

[0057] The daily ground delivery volume, the minimum reserved ground delivery days, the single-batch transportation stock preparation scale corresponding to the factory-out transportation method, and the transportation cycle can be determined based on historical data. For example, based on the daily ground delivery volume of oil production, the ground delivery reserve days, the single-batch transportation stock preparation scale and the transportation cycle corresponding to three types of factory-out transportation methods of a refinery from 2017 to 2021, the daily ground delivery volume of oil production is obtained as a ten thousand cubic meters, the minimum reserved ground delivery days is b days, the single-batch transportation stock preparation scale corresponding to railway transportation is c ten thousand cubic meters per cycle, the transportation cycle corresponding to railway transportation is d days, the single-batch transportation stock preparation scale corresponding to waterway transportation is e ten thousand cubic meters per cycle, the transportation cycle corresponding to waterway transportation is f days, and the single-batch transportation stock preparation scale corresponding to pipeline transportation is g ten thousand cubic meters per cycle, and the transportation cycle corresponding to pipeline transportation is h days.

[0058] On the basis of the above embodiments, further, the inventory measurement model corresponding to the refinery includes a first seasonal inventory measurement sub-model; correspondingly, according to the first time series inventory data of each type of refined oil and the first seasonal inventory measurement sub-model, the first seasonal inventory corresponding to each type of refined oil is obtained.

[0059] Specifically, the inventory measurement model corresponding to the refinery includes a first seasonal inventory measurement sub-model, and the first seasonal inventory measurement sub-model is used to measure the first seasonal inventory of refined oil. The first seasonal inventory of refined oil refers to the refined oil that needs to be temporarily stored to cope with the short-term demand fluctuations and the imbalance contradictions caused by long-term seasonality.

[0060] Inputting the first time series inventory data of each type of refined oil into the first seasonal inventory measurement sub-model, the first seasonal inventory corresponding to each type of refined oil can be obtained. Among them, the measurement data of each type of refined oil includes the first time series inventory data of each type of refined oil. The first time series inventory data is the inventory data of refined oil in a set time period, such as the refined oil inventory in the past 12 months.

[0061] For example, the first seasonal inventory measurement sub-model can be constructed based on the seasonal decomposition (additive) method, or implemented by calling the seasonal decomposition model of existing software.

[0062] Based on the above embodiments, further, the inventory measurement model corresponding to the refinery includes an export inventory measurement sub-model; correspondingly, according to the single-batch transportation preparation scale and export transportation cycle corresponding to each type of export transportation method of each type of refined oil and the export inventory measurement sub-model, the export inventory corresponding to each type of refined oil is obtained.

[0063] Specifically, the inventory measurement model corresponding to the refinery includes an export inventory measurement sub-model, and the export inventory measurement sub-model is used to measure the export inventory of refined oil. The export inventory of refined oil refers to the inventory that needs to be prepared in advance due to the export demand of the smelter.

[0064] Inputting the single-batch transportation preparation scale and export transportation cycle corresponding to each type of export transportation method of each type of refined oil into the export inventory measurement sub-model, the export inventory corresponding to each type of refined oil can be obtained. Among them, the measurement data of each type of refined oil includes the single-batch transportation preparation scale and export transportation cycle corresponding to each type of export transportation method of each type of refined oil. The export transportation methods include but are not limited to water transportation, railway transportation, pipeline transportation, etc., which are set according to actual needs and are not limited in the embodiments of the present invention.

[0065] For example, the export inventory measurement sub-model includes Among them, C 3 represents the export inventory, in ten thousand cubic meters, S k represents the single-batch transportation preparation scale corresponding to the kth type of export transportation method, T k represents the export transportation cycle corresponding to the kth type of export transportation method, k is a positive integer and k is less than or equal to p, and p represents the type of export transportation method.

[0066] Based on the above embodiments, further, the measurement object is a sales enterprise. The sales enterprise may include multiple gas stations and oil depots.

[0067] Combined with the operation of the petroleum sales enterprise, the inventory of the sales enterprise includes five functions: bearing the bottom of the storage tank and the bottom of the tank, emergency reserve, in-transit transportation, turnover, and seasonal adjustment, corresponding to four types of inventory in logistics. Then, the inventory of the petroleum sales enterprise can be subdivided into: the bottom inventory of the gas station oil tank, the bottom inventory of the oil depot, the emergency inventory, the in-transit inventory, the turnover inventory, and the seasonal inventory.

[0068] Combined with the meaning of reasonable inventory and the functional composition of the inventory of the sales enterprise, the reasonable inventory upper limit and reasonable inventory lower limit of the sales enterprise can be expressed as:

[0069] The reasonable inventory lower limit of the sales enterprise = non-movable inventory + turnover inventory + emergency inventory

[0070] The reasonable inventory upper limit of the sales enterprise = reasonable inventory lower limit + seasonal inventory

[0071] Among them, the non-movable inventory is equal to the sum of the bottom inventory of the gas station oil tank, the bottom inventory of the oil depot, and the in-transit inventory.

[0072] Combined with the current operation mode of the enterprise and the functional composition of the inventory, exploring the upper and lower limits of the reasonable inventory of refined oil through different inventory types is conducive to improving the accuracy of obtaining the reasonable inventory range.

[0073] Figure 3 It is a schematic flowchart of the refined oil inventory calculation method provided by the third embodiment of the present invention. As Figure 3 shown, obtaining the reasonable inventory range of each type of refined oil according to the measurement data of each type of refined oil and the corresponding inventory measurement model of the sales enterprise includes:

[0074] S301. Obtain the second reasonable inventory lower limit of each type of refined oil according to the non-movable inventory, the second turnover inventory, and the emergency inventory of each type of refined oil of the sales enterprise; among them, the non-movable inventory of each type of refined oil is equal to the sum of the bottom inventory of the gas station oil tank, the bottom inventory of the oil depot, and the in-transit inventory of the non-movable inventory of each type of refined oil; the second turnover inventory of each type of refined oil is equal to the sum of the gas station turnover inventory and the oil depot turnover inventory of each type of refined oil.

[0075] Specifically, for each type of refined oil of the sales enterprise, the sum of the non-movable inventory, the second turnover inventory, and the emergency inventory of each type of refined oil can be calculated as the second reasonable inventory lower limit of each type of refined oil. Among them, the non-movable inventory of each type of refined oil is equal to the sum of the bottom inventory of the gas station oil tank, the bottom inventory of the oil depot, and the in-transit inventory of the non-movable inventory of each type of refined oil; the second turnover inventory of each type of refined oil is equal to the sum of the gas station turnover inventory and the oil depot turnover inventory of each type of refined oil.

[0076] S302. Obtain the second reasonable inventory upper limit of each type of refined oil according to the second reasonable inventory lower limit of each type of refined oil and the second seasonal inventory of each type of refined oil.

[0077] Specifically, for each type of refined oil of the sales enterprise, the sum of the second reasonable inventory lower limit of each type of refined oil and the second seasonal inventory of each type of refined oil can be calculated as the second reasonable inventory upper limit of each type of refined oil.

[0078] On the basis of the above embodiments, further, the inventory measurement model corresponding to the sales enterprise includes a bottom inventory measurement sub-model of the gas station oil tank; correspondingly, according to the reserved liquid level height, the oil tank radius, and the oil tank length of each gas station oil tank of each type of refined oil and the bottom inventory measurement sub-model of the gas station oil tank, the bottom inventory of the gas station oil tank of each type of refined oil is obtained.

[0079] Specifically, the inventory calculation model corresponding to the sales enterprise includes a gas station oil tank bottom inventory calculation sub-model, which is used to calculate the gas station oil tank bottom inventory of finished oil. The gas station oil tank bottom inventory of finished oil refers to the inventory that cannot be completely extracted due to objective reasons such as the gas station oil tank type and the oil pump pipeline inlet height during normal operation.

[0080] By inputting the reserved liquid level height, tank radius and tank length of each gas station tank of each type of refined oil into the gas station tank bottom inventory calculation sub-model, the gas station tank bottom inventory of each type of refined oil can be obtained. Among them, the calculation data of each type of refined oil of the sales enterprise includes the reserved liquid level height, tank radius and tank length of each gas station tank of each type of refined oil.

[0081] For example, the oil tank at a gas station is a horizontal cylindrical tank, and the sub-model for calculating the bottom inventory of the oil tank at the gas station is in, h j =2r j β / α, C 4 Indicates the oil tank bottom inventory at the gas station, L j A represents the length of the oil tank of the jth gas station. j represents the cross-sectional area of ​​the finished oil corresponding to the reserved liquid level height of the oil tank of the jth gas station, r j represents the radius of the oil tank of the jth gas station, h j represents the length of the oil tank of the j-th gas station, and α represents the length of 2r j Make α equal divisions.

[0082] On the basis of the above embodiments, further, the inventory calculation model corresponding to the sales enterprise includes an oil depot bottom inventory calculation sub-model; accordingly, the oil depot bottom inventory of each type of finished oil is obtained according to the bottom tank height and oil depot radius of each oil depot of each type of finished oil and the oil depot bottom inventory calculation sub-model.

[0083] Specifically, the inventory calculation model corresponding to the sales enterprise includes an oil depot bottom inventory calculation sub-model, which is used to calculate the oil depot bottom inventory of finished oil. The oil depot bottom inventory of finished oil refers to the inventory that cannot be drawn out in time due to objective conditions such as oil tank type and oil pumping port height when the oil depot is operating normally.

[0084] By inputting the bottom tank height and radius of each oil depot of each type of refined oil into the oil depot bottom inventory calculation sub-model, the bottom inventory of each type of refined oil can be output. Among them, the calculation data of each type of refined oil of the sales enterprise includes the bottom tank height and radius of each oil depot of each type of refined oil. The bottom tank height refers to the height of the refined oil that cannot be extracted and used in the oil depot.

[0085] For example, the oil depot is in the shape of a cylinder, and the sub-model for calculating the inventory at the bottom of the oil depot includes where C 5 represents the inventory at the bottom of the oil depot, R e represents the radius of the e-th oil depot, h e represents the oil depot radius of the e-th oil depot, e is a positive integer and e is less than or equal to U, U represents the number of oil depots, and π represents the pi.

[0086] Based on the above embodiments, further, the inventory calculation model corresponding to the sales enterprise includes a sub-model for calculating the in-transit inventory; accordingly, according to each in-transit inventory type of each type of refined oil, the capacity corresponding to each in-transit inventory type, the in-transit ratio corresponding to each in-transit inventory type, and the sub-model for calculating the in-transit inventory, the in-transit inventory of each type of refined oil is obtained.

[0087] Specifically, the inventory calculation model corresponding to the sales enterprise includes a sub-model for calculating the in-transit inventory, and the sub-model for calculating the in-transit inventory is used to calculate the in-transit inventory of refined oil. The in-transit inventory of the refined oil of the sales enterprise refers to the quantity of refined oil in the process of transportation.

[0088] Inputting each in-transit inventory type of each type of refined oil, the capacity corresponding to each in-transit inventory type, and the in-transit ratio corresponding to each in-transit inventory type into the sub-model for calculating the in-transit inventory, the in-transit inventory of each type of refined oil can be output. Among them, the measurement data of each type of refined oil of the sales enterprise includes each in-transit inventory type of each type of refined oil, the capacity corresponding to each in-transit inventory type, and the in-transit ratio corresponding to each in-transit inventory type. The in-transit inventory types include but are not limited to road, railway, pipeline, shipping, etc., which are set according to actual needs, and are not limited in the embodiments of the present invention. The capacity corresponding to the in-transit inventory type refers to the total volume of refined oil that the transportation tool corresponding to the in-transit inventory type can accommodate. For example, if the in-transit inventory type is road, then the capacity corresponding to the in-transit inventory type is the available tank capacity of the road oil tanker for transporting refined oil; if the in-transit inventory type is railway, then the capacity corresponding to the in-transit inventory type is the available tank capacity of the railway tank car for transporting refined oil; if the in-transit inventory type is shipping, then the capacity corresponding to the in-transit inventory type is the oil tanker's warehouse capacity for transporting refined oil. The in-transit ratio corresponding to the in-transit inventory type is set according to actual experience and is not limited in the embodiments of the present invention.

[0089] For example, the sub-model for calculating the in-transit inventory includes where C 6 represents the in-transit inventory, V f represents the capacity corresponding to the f-th in-transit inventory type, and γ f represents the in-transit ratio corresponding to the f-th in-transit inventory type.

[0090] Based on the above embodiments, further, the inventory measurement model corresponding to the sales enterprise includes a gas station turnover inventory measurement sub-model; correspondingly, according to the number of gas stations corresponding to each type of refined oil, the average delivery cycle and daily sales volume corresponding to each type of ex-factory transportation method of each gas station, and the gas station turnover inventory measurement sub-model, the gas station turnover inventory of each type of refined oil is obtained.

[0091] Specifically, the inventory measurement model corresponding to the sales enterprise includes a gas station turnover inventory measurement sub-model, and the gas station turnover inventory measurement sub-model is used to measure the gas station turnover inventory of refined oil. The gas station turnover inventory of the refined oil of the sales enterprise refers to the inventory that the gas station must reserve to ensure normal supply.

[0092] Inputting the number of gas stations corresponding to each type of refined oil, the average delivery cycle and daily sales volume corresponding to each type of ex-factory transportation method of each gas station into the gas station turnover inventory measurement sub-model, the gas station turnover inventory of each type of refined oil can be obtained. Among them, the measurement data of each type of refined oil includes the number of gas stations corresponding to each type of refined oil, the average delivery cycle and daily sales volume corresponding to each type of ex-factory transportation method of each gas station.
