Description

Technical Field

[0001] The present application relates to the technical field of engineering management, and in particular to a method, system, device and storage medium for scheduling raw materials of a concrete mixing station. Background Art

[0002] In large-scale engineering construction projects, there is a certain linear or nonlinear quantitative relationship between different raw materials. If the procurement and inventory management of different raw materials are not coordinated enough, conflicts may arise and affect the progress of engineering construction.

[0003] Cost control is the core link in the procurement and management of raw materials. However, existing cost control methods usually consider a single factor, such as purchase price or inventory cost, which leads to inaccurate and incomplete cost control and cannot accurately reflect the actual cost of raw materials. Especially in a complex and changing market environment, it may lead to the failure of cost control and affect the production efficiency of enterprises. Summary of the invention

[0004] In order to reduce the cost of purchasing and managing raw materials for a concrete mixing plant, the present application provides a raw material scheduling method, system, device and storage medium for a concrete mixing plant.

Then, all available raw materials in the concrete mixing station are retrieved, and the retrieved raw materials are marked as actual raw materials. Then, the target raw materials and actual raw materials of the same type are compared one by one. If it is determined that the actual raw materials in the concrete mixing station cannot meet the raw materials required for the construction project, the insufficient raw materials are used as the raw materials to be supplemented, and the related raw materials and the scheduling raw materials are determined based on the raw materials to be supplemented. Then, it is analyzed which scheduling method has a lower cost, using related raw materials instead of raw materials to be supplemented and retrieving the same raw materials to be supplemented from the raw material warehouse, so as to facilitate the selection of a scheduling method with lower cost, so that the present application achieves the purpose of reducing the cost of purchasing and managing raw materials for concrete mixing stations.

[0007] In a possible implementation, in the separately calculating the cost scores of the associated raw materials and the scheduled raw materials, calculating the cost scores of the associated raw materials includes: Determining an inventory score according to the type and inventory quantity of the associated raw materials, wherein the inventory quantity is the quantity of the associated raw materials stored in the concrete mixing station; Determine the purchase score according to the purchase price and usage frequency of the associated raw materials, wherein the usage frequency is used to reflect the number of times the associated raw materials are called; Determine a transportation score according to the transportation distance of the associated raw materials, where the transportation distance refers to the distance between a raw material warehouse storing the associated raw materials and the concrete mixing station; Calculating the sum of the inventory score, the purchase score and the transportation score to obtain a first score; Determining a first weight according to the engineering project and the associated raw materials, the first weight being used to reflect the difference between the engineering quality obtained when the associated raw materials are used as the raw materials to be supplemented and the engineering quality required by the engineering project; The product of the first score and the first weight is calculated to obtain the cost score of the associated raw material.

[0009] In a possible implementation, determining the purchase score according to the purchase price and usage frequency of the associated raw materials includes: F2=s*v*p, where F2 is the purchase score, s is the purchase price per unit volume of the associated raw materials, v is the total volume of the associated raw materials, p=1+di / d0, di is the number of times the associated raw materials have been called in the past period of time, and d0 is the number of times all types of raw materials in the concrete mixing station have been called in the same past period of time.

[0010] In a possible implementation manner, determining the first weight according to the engineering project and the associated raw materials includes: Determine the items included in the engineering quality based on the engineering project, where the items are the functions of the main structure required to be constructed in the engineering project; A deep neural network model is used to predict the number of items that the main structure constructed when the associated raw materials are used to replace the raw materials to be supplemented has; A first weight is obtained according to the items included in the engineering quality and the prediction results of the deep neural network model, including: W1=1-Hi / H0, wherein W1 is the first weight, Hi is the number of items of the main structure obtained by the deep neural network model when predicting that related raw materials are used instead of the raw materials to be supplemented, and H0 is the number of items included in the main structure set in the engineering project.

[0011] By adopting the above technical solution, when calculating the cost score of related raw materials, various factors affecting the cost score are considered in depth, such as the volume, storage conditions, inventory of related raw materials, etc., which affect the management cost of the concrete mixing plant; the purchase price and frequency of use of related raw materials, etc., which affect the purchase cost; when the related raw materials are exhausted, the distance between the raw material warehouse storing the related raw materials and the concrete mixing plant affects the transportation cost; and when the related raw materials are used to replace the raw materials to be supplemented in the construction of the project, the gap between the actual functions that can be achieved and the functions required in the project will also affect the final choice. Therefore, the cost score of the related raw materials is calculated by combining multiple influencing factors to ensure the accuracy of the calculated cost score of the related raw materials.

[0012] In a possible implementation manner, in the separately calculating the cost scores of the associated raw materials and the scheduled raw materials, calculating the cost score of the scheduled raw materials includes: The basic score is determined according to the transportation distance and the scheduling node of the scheduled raw materials, wherein the transportation distance is the distance between the raw material warehouse storing the scheduled raw materials and the concrete mixing station, and the scheduling node is the station passed or parked during the transportation of the scheduled raw materials; Determine a second weight according to the scheduling time of the scheduled raw materials, where the scheduling time is the time for transporting the scheduled raw materials to arrive at the concrete mixing station; The product of the basic score and the second weight is calculated to obtain the cost score of the scheduled raw material.

[0014] By adopting the above technical solution, when calculating the cost score of the dispatched raw materials, we also deeply consider various factors that affect the cost score, such as the distance between the raw material warehouse where the dispatched raw materials are stored and the concrete mixing plant, the dispatch nodes in the transportation process, etc., which affect the basic cost; and when using the dispatched raw materials, vehicles are required to transport the dispatched raw materials from the raw material warehouse to the concrete mixing plant, which takes time, and whether the transportation time reaches the time required by the project will also affect the final choice. Therefore, the cost score of the dispatched raw materials is calculated by combining multiple influencing factors to ensure the accuracy of the calculated cost score of the dispatched raw materials.

[0015] In a second aspect of the present application, a raw material scheduling system for a concrete mixing plant is provided. The system comprises: A first determination module is used to determine target raw materials according to the engineering project, wherein the target raw materials are raw materials required for executing the engineering project; A second determination module is used to determine the raw materials to be replenished according to the target raw materials and actual raw materials, wherein the actual raw materials are the raw materials available in the concrete mixing station; A third determination module is used to determine associated raw materials and scheduled raw materials based on the raw materials to be replenished, wherein the associated raw materials are raw materials that can replace the raw materials to be replenished to participate in the construction of the engineering project, and the scheduled raw materials are raw materials stored in the raw material warehouse and of the same type as the raw materials to be replenished; A data processing module, used to calculate the cost scores of the associated raw materials and the scheduled raw materials respectively, wherein the cost scores are proportional to the costs; A data generation module is used to select one of the associated raw materials and the scheduled raw materials as the raw material to be replenished according to the cost score.

[0023] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed. However, as long as it is within the scope of the claims of the present application, it shall be protected by the patent law.

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] Figure 1 A schematic diagram of an exemplary operating environment in which embodiments of the present application can be implemented is shown, in which a raw material warehouse, a concrete mixing plant and a dispatching center are provided. The raw material warehouse and the concrete mixing plant exchange information via the Internet. The dispatching center accesses the Internet via a mobile wireless network, and then exchanges information with the raw material warehouse and the concrete mixing plant respectively via the Internet.

[0026] Among them, the raw material warehouse is the site where the manufacturer that produces raw materials or the distributor that stores raw materials is located. For example, cement plants, quarries, etc. are all raw material warehouses.

[0027] Concrete mixing station is mainly composed of five systems including mixing main machine, material weighing system, material conveying system, material storage system and control system and other ancillary facilities. Concrete mixing station has high mechanization and automation, so its productivity is also high, and it can ensure the quality of concrete and save cement. It is often used in large and medium-sized water conservancy, power, bridge and other projects with large concrete engineering volume, long construction period and concentrated construction sites. In this example, in addition to being able to achieve the ratio between raw materials, the concrete mixing station also has a certain storage function, that is, it can temporarily store some commonly used raw materials.

[0028] There are multiple servers in the dispatch center, which are used to support the dispatch center to receive engineering projects and assign them to corresponding concrete mixing plants. At the same time, the dispatch center can also monitor the consumption of raw materials in the concrete mixing plants in real time. For concrete mixing plants with insufficient raw materials, timely intervention is carried out with cost control as the core, ensuring that the concrete mixing plants meet the requirements of the engineering projects while reducing investment costs.

[0029] It should be noted that Figure 1 The operating environment shown is only illustrative and is not intended to limit the application or use of the embodiments of the present application. For example, the operating environment may include multiple raw material warehouses and multiple concrete mixing plants, and the dispatch center can simultaneously monitor the raw material consumption in multiple concrete mixing plants.

[0030] Figure 2 The flowchart of the method for scheduling raw materials of a concrete mixing station according to an embodiment of the present application is shown, and the method is mainly executed by the above-mentioned scheduling center. Specifically, the main process of the method for scheduling raw materials of a concrete mixing station is described as follows.

[0031] Step S100: determining target raw materials according to the engineering project, where the target raw materials are the raw materials required for executing the engineering project.

[0032] The dispatch center receives engineering projects entrusted by customers. Engineering projects mainly include information such as project location, project cost, project scale, project quality and construction period. The project location refers to the location of the construction project, the project cost refers to the expected cost required to complete the project, and the project scale refers to the size and scope of the project. Engineering quality refers to the comprehensive characteristics required by customers and in line with the standards of engineering construction, including the physical quality of the project, such as whether the foundation is solid, whether the main structure is safe, and whether the ventilation and lighting are reasonable, that is, the main structure required to be constructed in the project has the function. Secondly, engineering quality may also include the quality of work that forms the physical quality, such as the efficiency of engineering construction. The construction period refers to the entire process of the construction project from the beginning to the end, which is mainly divided into three stages: decision-making period, implementation period and production operation period.

[0033] The dispatch center will divide the raw materials required for each stage according to the scale of the project and the construction period, thereby generating production tasks that include production time and the raw materials required within the production time, and assign the production tasks to the concrete mixing station located at the project site, which will perform the production tasks. Then, the dispatch center will retrieve the consumption of raw materials in the concrete mixing station that needs to perform the production tasks in real time. For concrete mixing stations with insufficient raw materials, for example, when the inventory of at least one type of raw materials in the concrete mixing station is lower than the preset minimum threshold, the dispatch center will mark all the raw materials involved in the production tasks as target raw materials, that is, obtain a list of raw materials required to execute the project.

[0034] The above raw material inventory refers to the quantity of raw materials stored and available in the concrete mixing plant.

[0035] Step S200: determining raw materials to be replenished according to target raw materials and actual raw materials, where the actual raw materials are raw materials available in the concrete mixing station.

[0036] After obtaining the target raw materials, the available raw materials in the concrete mixing station are retrieved, and the available raw materials are marked as actual raw materials. Then, the target raw materials and actual raw materials of the same type are compared. If the target raw materials are greater than the actual raw materials, that is, the raw materials in the concrete mixing station do not meet the raw materials required by the construction project, the raw materials of this type are marked as raw materials to be supplemented, and then the process goes to step S300. Otherwise, if the target raw materials and actual raw materials of each type are compared one by one and it is found that the target raw materials are less than or equal to the actual raw materials, it means that although the raw materials in the concrete mixing station are not much, they can meet the raw materials required by the construction project, so the concrete mixing station operates normally according to the production task.

[0037] Step S300: Determine associated raw materials and scheduled raw materials based on the raw materials to be replenished. The associated raw materials are raw materials that can replace the raw materials to be replenished and participate in the construction of the engineering project. The scheduled raw materials are raw materials stored in the raw material warehouse and of the same type as the raw materials to be replenished.

[0038] Establish a related raw material network in the dispatch center in advance, and determine the correlation and substitutability between various raw materials through big data analysis. Therefore, after determining the type of raw materials to be replenished, match the related raw materials that are substitutable with the raw materials to be replenished from the related raw material network.

[0039] At the same time, after determining the type of raw materials to be replenished, the raw materials stored in the raw material warehouse and of the same type as the raw materials to be replenished will be used as dispatched raw materials, that is, the dispatched raw materials are raw materials that need to be transported from the raw material warehouse to the concrete mixing station by vehicles.

[0040] Step S400: Calculate the cost scores of the associated raw materials and the scheduled raw materials respectively, and the cost scores are proportional to the costs.

[0041] Here, step S410 takes the calculation of the cost score of the associated raw materials as an example, and step S410 is composed of steps S411 to S416.

[0042] Step S411: Determine the inventory score according to the type and inventory quantity of the associated raw materials.

[0043] The type of related raw materials determines the volume and storage conditions of the related raw materials. When the volume of the related raw materials is larger and the storage conditions are stricter, if the inventory of the related raw materials is also larger, the cost of managing the related raw materials for the concrete mixing station will be higher. Therefore, this example calculates the corresponding inventory score based on the type and inventory of the related raw materials, specifically: F1=(V+C)*k, where F1 is the inventory score, V is the volume cost, V is related to the volume of the associated raw materials, C is the storage condition cost, C is related to the storage conditions of the associated raw materials, and k is the inventory adjustment coefficient, k is related to the inventory of the associated raw materials.

[0044] Wherein, V=v*f, v is the total volume of the associated raw materials, which is obtained based on the associated raw materials stored and available in the concrete mixing plant, and f is the storage cost per unit volume of the associated raw materials. If the associated raw materials are in bags, then f is the storage cost per bag, which is uploaded by the concrete mixing plant.

[0045] C=v*c, v is the total volume of the associated raw materials, which is obtained based on the associated raw materials stored and available in the concrete mixing plant, and c is the facility cost for storing the associated raw materials. For example, when the associated raw material is cement, it needs to be stored in a rain-proof warehouse, and the rental fee for the warehouse storing cement is the facility cost of the associated raw materials. It should be noted that the above storage fee f is the sum of the rental fee per unit volume of the associated raw materials and the labor management fee.

[0046] k=1+(v-v0) / v0. Similarly, v is the total volume of related raw materials, and v0 is the inventory threshold of related raw materials. Because the concrete mixing station has the conditions to store related raw materials, but the storage quantity is not as large as the quantity stored in the raw material warehouse, so when the total volume of related raw materials exceeds the storage threshold, the concrete mixing station needs to add a warehouse for storing related raw materials, and the management cost is also rising. Therefore, the maximum inventory that the concrete mixing station can currently store is used as the storage threshold v0.

[0047] Step S412: Determine the purchase score according to the purchase price and usage frequency of the associated raw materials.

[0048] If the purchase price of the related raw materials is higher than that of the raw materials to be replenished, and the frequency of use is also relatively frequent, it is inevitable to re-purchase the related raw materials after the related raw materials are used as the raw materials to be replenished, and the purchase cost will be higher. Therefore, this example determines the purchase score based on the purchase price and frequency of use of the related raw materials, specifically: F2=s*v*p, where s is the purchase price per unit volume of the associated raw materials, which is set according to the market price, v is the total volume of the associated raw materials, and p is the usage frequency coefficient, which is related to the usage frequency of the associated raw materials, that is, p=1+di / d0, di is the number of times the associated raw materials have been called in the past period of time, specifically the number of times they have participated in the construction of engineering projects, and d0 is the number of times all types of raw materials in the concrete mixing plant have been called in the same past period of time, such as one month, two months,..., one year, etc., and there is no restriction here.

[0049] Step S413: Determine the transportation score according to the transportation distance of the associated raw materials.

[0050] Usually, the raw material warehouse or concrete mixing plant has a fixed cooperative transport vehicle, so the vehicle for transporting the related raw materials usually does not change. Therefore, after the related raw materials are determined, the vehicle for transporting the related raw materials is basically locked and the startup fee of the vehicle is determined. The startup fee here refers to the fuel and driving fee consumed by the vehicle per kilometer, which is obtained based on the vehicle's historical transportation records. Therefore, as the distance between the raw material warehouse storing the related raw materials and the concrete mixing plant is longer, the transportation fee for transporting the related raw materials from the raw material warehouse will be higher after the related raw materials in the concrete mixing plant are exhausted.

[0051] Specifically, F3=Q1*L1, where Q1 is the fuel and driving fees consumed per kilometer by the vehicle transporting the related raw materials, and L1 represents the distance between the raw material warehouse storing the related raw materials and the concrete mixing plant, which is measured by the geographic information system (GIS) or navigation software.

[0052] Step S414: Calculate the sum of the inventory score, the purchase score, and the transportation score to obtain a first score.

[0053] Step S415: determining a first weight according to the engineering project and the associated raw materials, wherein the first weight is used to reflect the difference between the engineering quality obtained by construction when the associated raw materials are used as the raw materials to be supplemented and the engineering quality required by the engineering project.

[0054] First, retrieve the engineering quality in the project. The engineering quality here includes whether the main structure is solid, ventilated, lighted, and has working hours. In practical applications, additional items included in the engineering quality can be added as needed. Then, a deep neural network model is used to predict whether the main structure obtained by using related raw materials instead of the raw materials to be supplemented has four items: solid, ventilated, lighted, and has working hours. The deep neural network model is trained in advance by collecting the items that the related raw materials have participated in the construction of the project in the past as training samples.

[0055] Finally, the first weight is obtained according to the items included in the engineering quality and the prediction results of the deep neural network model, that is, W1=1-Hi / H0, where W1 is the first weight, Hi is the number of items that the main structure obtained by the deep neural network model predicts when the associated raw materials are used instead of the raw materials to be supplemented. The items here refer to the effect brought by the use of associated raw materials instead of the raw materials to be supplemented, which is better than or reaches the effect when the raw materials to be supplemented are used. For example, the ventilation volume required in the engineering quality is 20-30 cubic meters / (hour·person), and when the associated raw materials are used instead of the raw materials to be supplemented, the ventilation volume needs to be 20-30 cubic meters / (hour·person) or greater than 30 cubic meters / (hour·person), which indicates that the associated raw materials have the ventilation volume. H0 is the number of items included in the main structure set in the engineering quality and the specific value or range value of each item.

[0056] Step S416: Obtain the cost score of the associated raw materials according to the first score and the first weight.

[0057] Specifically, the calculation formula for the cost score of the associated raw materials is: Z1=Y*W1=(F1+F2+F3)*W1, where Z1 is the cost score of the associated raw materials, Y is the first score, and W1 is the first weight.

[0058] It should be noted that when there are multiple raw materials that can replace the raw materials to be replenished to participate in the construction of the engineering project, that is, when there are multiple types of related raw materials, each type of related raw materials can use the above steps S411 to S416 to calculate the corresponding cost score Z1.

[0059] In addition, step S420 takes the calculation of the cost score of the scheduled raw materials as an example, and for the sake of distinction, Z2 is used to represent the cost score of the scheduled raw materials. Step S420 is composed of steps S421 to S423.

[0060] Step S421: Determine the basic score according to the transportation distance and scheduling nodes of the scheduled raw materials.

[0061] Similar to step S413, the raw material warehouse or the concrete mixing station has a fixed cooperative transport vehicle, so the vehicle for transporting the scheduled raw materials usually remains unchanged. Therefore, after determining the scheduled raw materials, the vehicle for transporting the scheduled raw materials is basically locked and the startup fee of the vehicle is determined. The startup fee here also refers to the fuel and driving fees consumed by the vehicle per kilometer, which is obtained based on the historical transportation records of the vehicle. Therefore, as the distance between the raw material warehouse storing the scheduled raw materials and the concrete mixing station is longer, the transportation fee for transporting the scheduled raw materials from the raw material warehouse is higher.

[0062] At the same time, in the process of scheduling the transportation of raw materials, if there are more scheduling nodes (scheduling nodes such as warehouses, transfer points, and other stations where raw materials pass through or park during transportation scheduling), it will affect the complexity and cost of transportation, and each additional scheduling node may increase the risk of errors, delays and costs.

[0063] Therefore, this example determines the basic score based on the transportation distance and scheduling nodes of the scheduled raw materials. The specific calculation formula is: F4=G1+G2, where G1 is related to the transportation distance of the scheduled raw materials, G1=Q2*L2, where Q2 is the fuel and driving fees consumed per kilometer by the vehicle transporting the scheduled raw materials, and L2 represents the distance between the raw material warehouse storing the scheduled raw materials and the concrete mixing station. This distance is also measured through the geographic information system (GIS) or navigation software. G2 is related to the scheduling node, G2=n*r, n is the number of scheduling nodes, and r is the average cost consumed by all scheduling nodes, that is, the cost consumed by each scheduling node is collected in advance, and then the average cost consumed by all scheduling nodes is calculated and stored.

[0064] Step S422: Determine the second weight according to the scheduling time of scheduling the raw materials.

[0065] First, based on the production tasks assigned to the concrete mixing station, determine the time period for the concrete mixing station to perform the production tasks, and plan the specific operations performed at each time point within the time period, including the time for scheduling the raw materials to arrive at the concrete mixing station. In this example, the time for the scheduled raw materials to arrive at the concrete mixing station based on the production tasks is called the predicted time.

[0066] Then, the actual time for the scheduled raw materials to arrive at the concrete mixing station is calculated based on the distance between the raw material warehouse storing the scheduled raw materials and the concrete mixing station and the running speed of the vehicle.

[0067] Finally, the second weight is calculated based on the predicted time and the actual time, specifically: When the actual time is less than or equal to the predicted time, the calculation formula of the second weight is: W2=(T0-Ti) / T0, T0 is the predicted time, Ti is the actual time, Ti=L2 / υ, L2 represents the distance between the raw material warehouse storing the scheduled raw materials and the concrete mixing plant, υ represents the running speed of the vehicle transporting the scheduled raw materials, which is the average of the historical running speeds of the same type of vehicles when traveling on the L2 section. Therefore, when the actual time is less than the predicted time and the closer it is to the predicted time, the smaller the second weight W2 value is, indicating that the transported scheduled raw materials can be put into use sooner, thereby reducing the management fee for storing the scheduled raw materials; When the actual time is greater than the predicted time, the calculation formula of the second weight is: W2=1+(Ti-T0) / T0, T0 is the predicted time, Ti is the actual time, and the source of Ti can be found in the above introduction.

[0068] Step S423: Calculate the product of the basic score and the second weight to obtain the cost score of the scheduled raw materials. Therefore, the cost score of the scheduled raw materials is Z2=F4*W2=(G1+G2)*W2.

[0069] Step S500: Select one of the associated raw materials and the scheduled raw materials as the raw material to be replenished according to the cost score.

[0070] Finally, the cost scores of the associated raw materials and the scheduled raw materials are compared, and the scheduling method with the lowest cost score is selected as the final scheduling method, that is, if the cost score Z1 of the associated raw materials is less than the cost score Z2 of the scheduled raw materials, the associated raw materials are used as the raw materials to be replenished, and if there are multiple associated raw materials, the associated raw materials with the smallest cost score Z1 and the cost score Z1 less than the cost score Z2 are selected from the multiple associated raw materials as the raw materials to be replenished. Otherwise, when the cost score Z2 of the scheduled raw materials is the smallest, the scheduled raw materials are used as the raw materials to be replenished.

[0071] After the raw materials to be replenished are determined from the associated raw materials and the scheduled raw materials, the production task is started according to the selected raw materials to be replenished. For example, if the associated raw materials are selected, the associated raw materials are retrieved from the concrete mixing station, and then the production task is started. When the scheduled raw materials are selected, the vehicle is notified to transport the scheduled raw materials from the raw material warehouse. When the scheduled raw materials arrive at the concrete mixing station, the production task is started, thereby achieving the purpose of accurately scheduling raw materials and improving the construction efficiency of the engineering project.

[0072] In summary, the implementation principle of the raw material scheduling method of a concrete mixing station in the embodiment of the present application is as follows: First, when the raw material inventory of the concrete mixing station is insufficient, a list of raw materials required in the project is sorted out, and the raw materials on the raw material list are marked as target raw materials. Then all available raw materials in the concrete mixing station are retrieved, and the retrieved raw materials are marked as actual raw materials. Then, the target raw materials and actual raw materials of the same type are compared one by one. If it is determined that the actual raw materials in the concrete mixing station cannot meet the raw materials required for the construction project, the raw materials with insufficient quantity are used as the raw materials to be supplemented, and the associated raw materials and the scheduling raw materials are determined based on the raw materials to be supplemented. Then, it is analyzed which scheduling method has a relatively low cost, using the associated raw materials to replace the raw materials to be supplemented and retrieving the same raw materials to be supplemented from the raw material warehouse. Specifically, in the cost analysis process, a variety of factors affecting the cost are actually considered in depth, and the corresponding costs of each are calculated by combining multiple factors, so as to facilitate the selection of a scheduling method with a lower cost, so that the present application achieves the purpose of reducing the cost of purchasing and managing raw materials for concrete mixing stations.
