The application provides an erp management system and method, which can save deployment resources of the erp management system and ensure effective monitoring of profit values of each product line.
In a first aspect, the present application provides an erp management system.
Fig. 1 shows a block diagram of an erp management system in an embodiment of the present application.
Referring to fig. 1, the system includes a data acquisition module 110, a profit calculation module 120, and a calculation control module 130.
Wherein the data collection module 110 is configured to correspond to the product line one by one, and is configured to collect a set profit value of a product corresponding to the product line, a product amount of an order to be delivered, a stock amount of the product, and a planned production amount of the product; the profit calculation module 120 has a plurality, the number of the profit calculation modules 120 is smaller than the number of the data collection modules 110, the profit calculation module 120 is used for linking to the data collection modules 110 to calculate the expected profit value of the product line according to the established profit value of the corresponding product line of the linked data collection modules 110, the product quantity of the order to be delivered, the inventory quantity of the product and the planned production quantity of the product; the calculation control module 130 is used to control the linking of the profit calculation module 120 with the data acquisition module 110 according to the desired profit value of the product line. The calculation control module 130 has one.
Let n product lines of the enterprise have n >10, the number of data acquisition modules 110 is n, the number of profit calculation modules 120 has m, m < n, in general, m is between 0.2n and 0.8n, and the setting of m relates to the minimum link time interval between the profit calculation modules 120 and the data acquisition modules 110, which can be set according to specific monitoring requirements, in this embodiment, m=0.5n.
In the profit calculation module 120, the expected profit value is calculated in the following way:wherein E is a desired profit value,for a given profit value to be achieved,for the amount of product to be delivered to the order,is the profit per unit of the product,in order to be a stock quantity of the product,for the intended throughput of the product,for the pre-acquired risk factor(s),。
the expected profit value is used to calculate the profit that the product line is expected to be able to generate. The predetermined profit value refers to the total amount of profit for an order that has been delivered, which profit has occurred and can be considered fixed. The order to be delivered is signed, and the related profit can be obtained after the delivery is completed. Both the established profit and the profit of the order to be delivered can be considered as established profits, but the product is still in advance production, the sum of the product inventory and the product scheduling throughput must be greater than the product quantity to be delivered, the sum of the product inventory and the product scheduling throughput minus the product quantity of the order to be delivered is the advance throughput, and the profit of the advance throughput is a split risk, so that the split profit needs to be multiplied by a risk factor.
In the above, the planned production amount of the product is determined by the enterprise, and may be a fixed amount, or may be appropriately controlled within a range according to the production capacity, and may be a pre-obtained value.
How to reasonably determine the risk factors is described below.
In the embodiment of the application, the risk coefficient is calculated based on a historical order record of the product line. Specifically, the data collection module 110 is further configured to obtain a history order record of the corresponding product line product, where the history order record includes a product amount of the history order and a time of signing the history order.
The profit calculation module 120 is further configured to calculate the risk factor according to the historical order record of the product line corresponding to the linked data acquisition module 110.
In one example, a specific method of calculating the risk series is:wherein F is the number of risk stages,product quantity for the pre-acquired expected order; substituting the risk series into a pre-acquired coefficient series comparison table to obtain the risk coefficient.
The coefficient level comparison table is constructed based on enterprise experience data, and comprises a plurality of level ranges, wherein all the level ranges form all possible complete sets of risk levels, namely the risk levels fall in a certain level range. And setting a risk coefficient corresponding to each series range, so that the risk series can be substituted into the coefficient series comparison table to obtain a determined risk coefficient. The higher the risk level, the greater the corresponding risk coefficient and the less the corresponding actual risk may be.
In the above example, the method for calculating the product quantity of the pre-acquired expected order includes:in the method, in the process of the invention,for the pre-fetched product volume of the intended order,for the product quantity of the ith intent order,for the intent rate of the ith intent order,the time influence coefficient of the ith intention order is given, and n is the number of the intention orders.
The method for calculating the time influence coefficient comprises the following steps:in the method, in the process of the invention,for the predicted time of issuance for the ith intent order, T is the current time,in order to set the time interval to be a predetermined time interval,for the reference time to be used,。
in this example, the time-affecting factor may be controlled between 0.1-0.9 to reasonably calculate the product volume of the intended order.
By combining the above, reasonable calculation of the risk coefficient can be realized.
How the calculation control module 130 implements the link control of the calculation module and the data acquisition module 110, for example, is described below.
When a profit computation module 120 is linked to a data collection module 110 and completes computation of the desired profit value for a product line, the computation control module 130 determines the time at which the product line needs to compute the desired profit value next time based on the expected profit value computed this time and the previously computed historical expected profit value for the product line.
Specifically, when a profit calculation module 120 is linked to a data collection module 110 and completes calculation of expected profit values for a product line, a specified number of historical expected profit values for the product line corresponding to the data collection module 110 before that time are obtained;
the appointed number of historical expected profit values and the expected profit values at the moment are ordered from first to last according to time, and the appointed number of profit value variation is obtained according to the calculation mode that the previous value is subtracted from the next value in every two adjacent values;
judging whether the profit value variation amounts are all larger than 0 or not larger than 0, and calculating profit variation speed according to the profit value variation amount; if yesIf otherwise->Wherein v is profit change speed, < + >>For the desired profit value at that moment, +.>For specifying the first one of a number of historic expected profit values>For the time and the most of the specified quantity of historic expected profit valuesThe duration between the historic occurrence moments of the preceding one,/->At the time of the preset speed, the speed is set to be the preset speed,quantity of profit change greater than 0, < >>A quantity of profit margin variation of not more than 0;
determining a profit level interval in which a desired profit value at the moment is located based on pre-constructed profit level data, the profit level data including a plurality of profit level intervals, each profit level interval including an interval lower limit and an interval upper limit;
the desired time interval is calculated and,wherein G is a desired time interval,and->The upper limit and the lower limit of the profit level section where the expected profit value at the moment is located are respectively;
judging whether the expected time interval is in a time threshold range or not, wherein the time threshold range comprises a lower time interval limit and an upper time interval limit, if the expected time interval is in the time threshold range, enabling the link time interval to be the expected time interval, if the expected time interval is smaller than the lower time interval limit, enabling the link time interval to be the lower time interval limit, and if the expected time interval is larger than the upper time interval limit, enabling the link time interval to be the upper time interval limit;
the linking of the profit computation module 120 with the data collection module 110 is controlled according to the linking time interval, and after the linking time interval at that time, the idle profit computation module 120 is controlled to link with the data collection module 110.
In summary, the number of profit calculation modules 120 to be deployed in the erp management system can be reduced, and the calculation control module 130 is adopted to reasonably control the time for calculating the expected profit value of the product line by the profit calculation modules 120, so that the weight reduction of the erp management system is ensured, and the effective monitoring of the expected profit value of the product line is ensured.
