[0002] Framework agreements and material groups are commonly used forms of material procurement. For enterprises that use framework agreements and material groups for material procurement, when specific projects have not yet been issued, managers need to predict material demand based on historical experience, and the prediction result is all the materials required for the project. On this basis, it is also necessary to subtract the amount of materials that have not been delivered in the agreement, that is, the remaining amount of the agreement, to obtain the actual amount of materials that need to be purchased.

[0003] However, the calculation of the agreed remaining quantity is complex, and the detailed materials in the material group often change. The current method of reducing the forecast demand for materials has low accuracy. Summary of the invention

[0041] Figure 3 is a schematic diagram of a terminal provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0042] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0043] In order to make the purpose, technical solutions and advantages of the present invention more clear, specific embodiments will be described below in conjunction with the accompanying drawings.

[0044] See also Figure 1 , which shows a flowchart of the implementation of the method for reducing the predicted demand provided by an embodiment of the present invention, the method is applied to a terminal device, and is described in detail as follows:

[0045] Step 101, obtaining forecast demand and historical agreements, wherein the forecast demand includes at least one category of first material groups and forecast quantities of each category of first material groups, and the historical agreements include at least one category of second material groups and surplus quantities of each category of second material groups.

[0046] In this embodiment, the forecast demand can be the forecast demand obtained by the planning management personnel based on the historical experience when the specific project has not been issued and the initial design plan has not been completed. The historical agreement can be an agreement signed before the forecast demand and not fully delivered, usually a framework agreement using the material group model. Each type of material group corresponds to a material group ID, and a material group is used to represent a group of materials. The forecast quantity of each type of first material group represents the forecast demand quantity or forecast demand amount of each type of first material group. The balance of each type of second material group represents the undelivered quantity or undelivered amount of each type of second material group.

[0047] Step 102, for any category, obtain the material quantity of the first material group corresponding to the category as the first material quantity of the category, obtain the material quantity of the second material group corresponding to the category as the second material quantity of the category, and calculate the material change rate of the category based on the first material quantity and the second material quantity of the category.

[0048] In this embodiment, the material quantities corresponding to the same category of material group in different time periods may be different. Since the forecast demand and the historical agreement correspond to different time periods, if there are technical reasons that cause the material composition in a certain category of material group to change, the terminal device calculates the material change rate of the category based on the material quantity of the category of material group before the change and the material quantity after the change, that is, the material change rate of the category is calculated based on the first material quantity and the second material quantity of the category. The reduction logic of the category is determined based on the material change rate of the category.

[0049] Step 103: for each category, determine the predicted reduction amount of the first material group corresponding to the category based on the material change rate of the category and the predicted amount of the first material group corresponding to the category.

[0050] In this embodiment, the smaller the material change rate of a certain category is, the less the material components of the material group corresponding to the category are increased, that is, the more the proportion of the predicted quantity that can be reduced by the historical agreement is increased. Therefore, the reduction ratio of the predicted quantity of the first material group corresponding to the category can be determined based on the material change rate of the category, and a part of the predicted quantity of the first material group corresponding to the category is used as the predicted reduction amount based on the reduction ratio. The predicted reduction amount represents the predicted quantity that can be reduced without considering the surplus in the historical agreement.

[0051] Step 104: for each category, the smaller value between the predicted reduction amount of the first material group corresponding to the category and the remaining amount of the second material group corresponding to the category is used as the actual reduction amount of the first material group corresponding to the category.

[0052] In this embodiment, after determining the predicted reduction amount of the first material group corresponding to the category, it is also necessary to compare it with the balance in the historical agreement. If the balance in the historical agreement is larger, it means that the historical agreement can fully reduce the predicted reduction amount, and the predicted reduction amount of the first material group corresponding to the category can be used as the actual reduction amount of the first material group corresponding to the category; if the balance in the historical agreement is smaller, it means that the historical agreement cannot meet the predicted reduction amount, and at most the balance in the historical agreement can be fully reduced, that is, the balance of the second material group corresponding to the category is used as the actual reduction amount of the first material group corresponding to the category.

[0053] In a possible implementation, the historical protocol is at least one;

[0054] The smaller value between the predicted reduction amount of the first material group corresponding to the category and the remaining amount of the second material group corresponding to the category is used as the actual reduction amount of the first material group corresponding to the category, including:

[0055] For each category, sum the balances of the second material group corresponding to the category in each historical agreement to obtain the total balance;

[0056] The smaller value between the predicted reduction amount of the first material group corresponding to the first category and the sum of the remaining amounts of the second material group corresponding to the first category is taken as the actual reduction amount of the first material group corresponding to the first category; the first category is any category.

[0057] In this embodiment, if there is one historical agreement corresponding to the first material group corresponding to the first category, the balance in the historical agreement is compared with the predicted reduction amount of the first material group corresponding to the first category to determine the actual reduction amount of the first material group corresponding to the first category. If there are more than or equal to two historical agreements corresponding to the first material group corresponding to the first category, the balances of all historical agreements corresponding to the first material group corresponding to the first category are summed, and the sum of the balances is compared with the predicted reduction amount of the first material group corresponding to the first category to determine the actual reduction amount of the first material group corresponding to the first category.

[0058] In a possible implementation, if the predicted reduction amount of the first material group corresponding to the first category is less than the sum of the remaining amounts of the corresponding second material group, the historical agreements are sorted from small to large according to the remaining amounts of the second material group corresponding to the first category;

[0059] The predicted reduction amount of the first material group corresponding to the first category is used to write off the surplus of the second material group corresponding to the first category in each historical agreement in order, until the remaining predicted reduction amount is not greater than 0, thereby obtaining the historical agreement after write-off.

[0060] In this embodiment, if the predicted reduction amount of the first material group corresponding to the first category is greater than the sum of the surplus of the corresponding second material group, all historical agreements corresponding to the first category will be reduced; if the predicted reduction amount of the first material group corresponding to the first category is less than the sum of the surplus of the corresponding second material group, there may be historical agreements that cannot be reduced, and it is necessary to determine which historical agreements can be reduced and which historical agreements cannot be reduced. In order to use as many historical agreements as possible, in this embodiment, the historical agreements with small surpluses are first reduced, and then the historical agreements with large surpluses are reduced until all the reduction amounts are used.

[0061] In a possible implementation, calculating the material change rate of the category based on the first material quantity and the second material quantity of the category includes:

[0062] The difference between the quantity of the first material and the quantity of the second material in the first category is taken as the material change amount of the first category; the first category is any category;

[0063] The ratio of the change amount of the first category of materials to the amount of the second material is calculated to obtain the change rate of the first category of materials.

[0064] In this embodiment, the material change rate of the first category is used to reflect the degree of change of the material composition of the material group corresponding to the first category. The greater the material change rate of the first category is, the more the material composition of the material group corresponding to the first category increases.

[0065] In a possible implementation, determining the predicted reduction amount of the first material group corresponding to the category based on the material change rate of the category and the predicted amount of the first material group corresponding to the category includes:

[0066] Determine the reduction ratio corresponding to the first category based on the material change rate of the first category; the first category is any category;

[0067] The product of the reduction ratio corresponding to the first category and the predicted quantity of the first material group corresponding to the first category is calculated to obtain the predicted reduction quantity of the first category.

[0068] In this embodiment, the corresponding reduction ratio is determined based on the range of the material change rate of the first category. Specifically, it can be:

[0069] (1) When there is no new material component in the material group (i.e. material change rate = 0), the predicted quantity will be reduced;

[0070] (2) When there is a new material component in the material group (i.e. material change rate > 0), in order to meet future matching needs, the material component is reduced according to the step ratio:

[0071] If the material change rate is not greater than 30%, the reduction ratio is 70%, and the remaining 30% of the forecast quantity is retained;

[0072] If the material change rate is not greater than 60%, the reduction ratio is 40%, and the remaining 60% of the forecast quantity is retained;

[0073] If the material change rate is greater than 60%, the reduction ratio will be 0, no reduction will be made, and the entire forecast quantity will be retained.

[0074] In a possible implementation, the balance includes the amount balance, the predicted reduction includes the predicted reduction amount, and the actual reduction includes the reduction amount;

[0075] After, for each category, the smaller value between the predicted reduction amount of the first material group corresponding to the category and the remaining amount of the second material group corresponding to the category is used as the actual reduction amount of the first material group corresponding to the category, the method further includes:

[0076] Get the price of the first material group corresponding to each category;

[0077] Subtract the corresponding actual reduction amount from the predicted reduction amount of the first material group corresponding to each category to obtain the reduced amount of the first material group corresponding to each category;

[0078] For each category, the ratio of the reduced amount of the first material group corresponding to the category to the price of the first material group corresponding to the category is calculated to obtain the reduced quantity of the first material group corresponding to the category.

[0079] In this embodiment, after determining the actual reduced amount, the terminal device deducts the reduced amount from the predicted amount to obtain the reduced amount, and then calculates the reduced quantity based on the reduced amount. The terminal device may also first determine the reduced quantity, and then determine the reduced amount based on the reduced quantity.

[0080] In a possible implementation, the historical protocol is at least one;

[0081] Get historical agreements, including:

[0082] Determine whether the first historical agreement is signed in the form of a material group; the first historical agreement is any historical agreement;

[0083] If the first historical agreement is not signed in the form of material groups, the material balance of the first category in the first historical agreement is divided by the first material quantity corresponding to the first category to obtain the balance of the second material group corresponding to the first category in the first historical agreement; the first category is any category.

[0084] In this embodiment, if there are multiple historical agreements, the signing time of each historical agreement may be different, so some historical agreements may not be signed in the form of material groups. At this time, the historical agreements that are not signed in the form of material groups can be converted into the form of material groups. The terminal device can sort out the material balances of each category in the first historical agreement, and then divide the material balance of the first category in the first historical agreement by the latest material quantity, that is, divide it by the first material quantity corresponding to the first category, to obtain the balance of the second material group corresponding to the first category in the first historical agreement.

[0085] In a specific embodiment, the method for reducing forecast demand provided by the present invention may include the following steps:

[0086] (1) Set the agreed inventory reduction threshold, set the agreed balance calculation ratio and reduction ratio corresponding to different material change rates for equipment material groups and material material groups, and set the activation date for procurement by material group mode. The activation date for procurement by material group mode is used to distinguish whether the historical agreement was signed according to the material group mode.

[0087] (2) Obtain the forecast demand to be reduced and determine the scope of reduction. The forecast demand to be reduced can be the forecast demand confirmed by the staff in the demand reduction system.

[0088] (3) Import historical agreement information into the demand reduction system. For historical agreements that are not purchased according to the material group model, they are sorted according to the latest mapping relationship between material groups and material components and then imported into the system. Historical agreement information is used to calculate material change rates and perform reductions.

[0089] (4) Calculate the material change rate of each category in each historical agreement, and calculate the benchmark material change rate by batch and benchmark material.

[0090] (5) Perform reduction based on historical agreements. According to the material group category in the forecast demand to be reduced, query the historical agreements with surplus, and obtain the agreement execution ratio and remaining amount information. Summarize the forecast amount in the forecast demand to be reduced by material group category and category ID, and allocate it to the agreement lines with surplus. Among them, each historical agreement has multiple agreement lines, and each agreement line corresponds to a category of material group.

[0091] The logic for allocating the forecast amount is as follows: Based on the "Material Group Category and Category ID" dimension, fill in the "Demand Forecast" one by one from small to large according to "Breakage", and the "Demand Forecast" amount = "Breakage" amount, until the filled-in amount = the total forecast amount.

[0092] After the allocation is completed, the system calculates according to the reduction ratio to determine the deductible amount, the reduced amount, and the amount after reduction.

[0093] The calculation logic of the reduction amount is as follows: when the balance of the first historical agreement ≧ the sum of all demand forecasts under the first historical agreement, the reduction amount = demand forecast; when the balance of the first historical agreement < the sum of all demand forecasts under the first historical agreement, the reduction amount is calculated line by line item starting from the line with the smallest agreement execution progress under the first historical agreement, and the reduction amount = demand forecast * reduction ratio, until the sum of the reduction amounts of all agreement lines under the first historical agreement = the agreement balance.

[0094] Calculation logic for the amount submitted after reduction: amount after reduction = total forecast amount - reduced amount.

[0095] (6) Update the original forecast purchase plan based on the reduced amount. Summarize the reduced amount according to the material group category and category ID, and then allocate it according to the amount of forecast demand. Determine the quantity to be purchased after the reduction using the following formula:

[0096] Quantity after reduction = apportionment amount / material group price.

[0097] (7) Update the original forecast purchase requisition based on the reduced quantity and execute the purchase process after the purchase requisition is approved.

[0098] The above steps are implemented by the staff to control the demand reduction system, and the demand reduction system can also count and display the data calculated in the above steps.

[0099] The embodiment of the present invention provides a method for reducing forecast demand, the method comprising: obtaining forecast demand and historical agreements, the forecast demand including at least one category of first material group and the forecast quantity of each category of first material group, the historical agreement including at least one category of second material group and the surplus of each category of second material group; for any category, obtaining the material quantity of the first material group corresponding to the category as the first material quantity of the category, obtaining the material quantity of the second material group corresponding to the category as the second material quantity of the category, and calculating the material change rate of the category based on the first material quantity and the second material quantity of the category; for each category, determining the forecast reduction amount of the first material group corresponding to the category based on the material change rate of the category and the forecast quantity of the first material group corresponding to the category; for each category, the smaller value of the forecast reduction amount of the first material group corresponding to the category and the surplus of the second material group corresponding to the category is used as the actual reduction amount of the first material group corresponding to the category. The present invention determines the corresponding forecast reduction amount based on the material change rate of each category, compares the forecast reduction amount with the surplus of the historical agreement to obtain an accurate actual reduction amount, and can accurately reduce the forecast demand.

[0100] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.
