The embodiment provides a method for generating a production form as shown in fig. 1, which includes:
and step S11, constructing a blank production form template according to the production cycle and a plurality of procedures of the target production line.
In step S12, a target projected production volume for each of a plurality of processes is determined.
Step S13, filling the blank production form template with the target planned output of each of the plurality of processes to generate a production form.
In the field of metallurgy, the target production line according to this embodiment may be one of a steel-making production line, a hot rolling production line, and a cold rolling production line, or may be a combination of several production lines, for example, the target production line may be a production line composed of steel making and hot rolling. The target production line includes a plurality of processes, and the relationship between the plurality of processes may be an upstream-downstream relationship or a parallel relationship. As shown in fig. 2, the method includes a step a1, a step a2, a step A3, a step B1, a step B2, a step C1, a step C2, a step C3, and the like, wherein the step a1 and the step B1 are in a vertical relationship, and the step a1 and the step a2 are in a parallel relationship.
The present embodiment constructs a blank production form template according to a production cycle based on a plurality of processes of a target production line. The production period can be a day, week, month, quarter period, etc. The blank production form template includes the name or number of each process, the target planned output of each process in the production cycle is determined through step S12, and the target planned output is filled into the blank production form template, so as to obtain the production form, and the target production line performs production according to the target planned output in the production form.
Specifically, each process in the blank production form template may be obtained from a process database, corresponding processes are obtained from the process database according to different target production lines, a corresponding blank production form template is generated according to the corresponding processes, and then the target planned yield of each process is determined according to a specific target planned yield determination mode, so as to complete the construction of the production form.
The step S12 specifically includes steps S21-S24.
Step S21, dividing the plurality of processes into a plurality of supply groups in a raw material supply relationship, each supply group of the plurality of supply groups including an upstream process that supplies raw material and a downstream process that receives raw material.
The upstream process a1 receives the raw material a, processes the raw material a to obtain a product a, and transmits the product a to the downstream process B1, and the downstream process B1 processes the product a as the raw material to obtain a product B, and transmits the product B to the corresponding downstream process for further processing.
The present embodiment divides a plurality of processes into a plurality of supply groups according to the material supply relationship, and the principle of determining whether the plurality of processes are in the same supply group includes: in principle 1, parallel processes are described as the same step, and principles 2 and 3 are executed for two adjacent steps. In principle 2, for a downstream process, one or more upstream processes that supply raw materials to the downstream process and the downstream process are divided into a supply group. In principle 3, for an upstream process (and the upstream process cannot be the downstream process mentioned in principle 2), the downstream process or processes to which the feedstock received the upstream process is provided and the upstream process are divided into a supply group.
For example, as shown in fig. 2, when the step a1, the step a2, and the step A3 are parallel steps, the step a1, the step a2, and the step A3 are classified into the same step; if the steps B1 and B2 are parallel steps, the steps B1 and B2 are divided into the same step. Using principle 1, if the process a1 and the process B1 belong to two different processes, and the two processes are adjacent to each other, the supply groups can be divided into the process a1, the process a2, the process A3, the process B1, and the process B2. As shown in fig. 2, in the downstream step B1, when the upstream step of supplying the raw material to the step B1 includes the steps a1, a2, and A3 using the principle 2, the steps a1, a2, A3, and B1 are divided into one supply group. In the upstream process A3, when the downstream process including the process B1 and the process B2, which receives the raw material supplied from the process A3, uses the principle 3, the process A3, the process B1, and the process B2 are divided into one supply group. In summary, it can be seen that the process a1, the process a2, the process A3, the process B1 and the process B2 are divided into the same supply group. Likewise, a supply group division as shown in fig. 3 may be obtained, including a first supply group, a second supply group, and a third supply group.
Each supply group may include a plurality of upstream processes and a plurality of downstream processes within the same supply group, the upstream processes being processes that supply raw materials to the downstream processes, and the downstream processes being processes that receive raw materials supplied from the upstream processes. However, in the same supply group, the upstream process does not need to supply material to every downstream process (e.g., process a2 in fig. 3 supplies material only to process B1), nor does the downstream process need to receive material supplied by every upstream process (e.g., process B2 in fig. 3 receives material only to process A3).
Step S22, for the downstream processes in each supply group, determines the raw material demand that needs to be accepted from the corresponding upstream process during the production cycle.
Since the material supply or production yield between the respective processes (particularly, between the processes having the material supply relationship) in the target production line is correlated, when determining the material demand to be received from the corresponding upstream process for the downstream process of each supply group, the material supply amount to be supplied by the downstream process as the upstream process is actually calculated. For example, as shown in fig. 3, the process B1 is a downstream process of the first supply group, and is also an upstream process of the second supply group, and for the first supply group, when step S22 is executed, it is determined that the raw material demand that the process B1 should receive from three upstream processes, i.e., the process a1, the process a2 and the process A3, and it is actually determined how much raw material demand should be needed for the process B1, and factors influencing the raw material demand of the process B1 include not only the process B1 itself but also downstream processes in the second supply group in which the process B1 is located, i.e., the process C1 and the process C2 (in the second supply group, the process B1 is an upstream process, and only the processes C1 and C2 have supply relations, so that the downstream processes corresponding to the process B1 in the second supply group include only the processes C1 and C2 and not the process C3). Thus, the raw material demand for the downstream process B1 in the first supply group is determined, and is actually the raw material demand required in the determination process B1 and subsequent processes (e.g., process C1 and process C2).
It can be seen that in actual operation, step S22 can be executed from the last supply group where the last process is located, so as to achieve the purpose of determining, for the downstream processes in each supply group, the raw material demand that needs to be accepted from the corresponding upstream process in the production cycle. For example, as shown in fig. 3, if the process D1 is the last process and is in the third supply group, the amount of raw material required for the downstream process D1 of the third supply group is only the amount of raw material required, and the yield required for the process D1 can be directly determined from the production order, and further how much raw material is required for the process D1 can be determined, and the raw material for the process D1 is supplied only from the process C1, so that the amount of raw material required for the downstream process C1 in the second supply group can be determined.
That is, in actual operation, the raw material demand of all the last steps (for example, step D1, step D2, step D3, and step D4) may be calculated first, and the raw material demand of the upstream step corresponding to the last step (for example, step C1, step C2, and step C3) may be calculated, that is, the raw material demand of each step may be determined step by step in the reverse direction of the production flow.
In summary, in step S22, only the required amount required when the process is the downstream process of the supply group is considered. However, although the raw material demand of the downstream process is known from the actual production situation, the raw material demand of the downstream process may not be satisfied by the upstream process, and therefore, it is necessary to perform step S23 in consideration of the upstream process, that is, in consideration of the raw material supply amount that the upstream process can provide.
In step S23, for the upstream process in each supply group, the supply amount of raw material to be supplied to the corresponding downstream process in the production cycle is determined.
For each process, whether it is an upstream process or a downstream process, in the case of a raw material satisfaction, the production thereof has an upper limit value within one production cycle, i.e. the production of a process within a production cycle (for example, one day) is of limited value; in the case where the raw material is not satisfied, the upper limit value in one day is correlated with the amount of the raw material. Step S23 is the maximum value that can be produced in the production cycle in view of the upstream process. That is, in step S23, for the upstream process of each supply group, the supply amount of its raw material, that is, the highest yield within the production cycle that can be processed from the actual raw material that can be obtained therefrom, is determined.
For example, if the maximum yield of the process B1 is 1000 tons in one day when the raw material is sufficient, the corresponding raw material supply amount is 1000 tons, that is, the sum of the raw materials that can be supplied to the process C1 and the process C2 in the process B1 is 1000 tons. In actual production, when a special situation of continuous material supply shortage occurs, a situation of raw material shortage may occur, and normally, each process is provided with a standard plan stock, and the stock quantity in the standard plan stock is generally three times to six times of a daily constant, so that the situation of raw material supply shortage exists only when the standard plan stock cannot be replenished for continuous days. If the shortage of the raw material occurs, the raw material usable in the step B1 is limited, and the amount of the raw material supplied is affected. For example, if the raw material can only be supplied to the process B1 for 800 tons, the corresponding raw material supply amount is 800 tons, i.e., the sum of the raw materials supplied to the process B1 for the process C1 and the process C2 is 800 tons.
In step S24, a target projected production volume for each of the plurality of processes is determined based on the raw material demand and raw material supply volumes for each of the plurality of supply groups.
After steps S22 and S23 are executed, the raw material demand amount and the raw material supply amount for each process are known, and the target planned production amount for each process can be determined based on the raw material demand amount and the raw material supply amount for each process and the raw material supply relationship between the processes.
In calculating the required amount of raw material and the supplied amount of raw material for each process, the yield of each process should be considered, for example, in the process B1, 1000 tons of raw material a are obtained from the processes a1, a2 and A3, but when the product B is obtained after processing the raw material a in the process B1, loss is usually generated, that is, 1000 tons of raw material a cannot be obtained, 1000 tons of product B should be obtained, and the product B actually obtained at the end should be the product of 1000 tons and the yield, for example, the yield is 0.9, and then 900 tons of product B obtained by processing 1000 tons of raw material a in the process B1 should be obtained. Therefore, the yield rate should be also considered when determining the target planned yield for each process, and the accuracy of the target planned yield can be improved.
In the embodiment, steps S11-S13 and S21-S24 all adopt a computer to realize automatic calculation, so that a worker can input necessary initial data (for example, the process related to a specific target production line, the required amount of raw materials that can be used in the first process, the production cycle, and the target yield that needs to be produced in the last process) into the computer, and the computer can perform logical operations according to steps S11-S13 and steps S21-S24, so as to quickly determine the target planned yield.
In conclusion, the target planned yield of each process can be determined quickly, the yield of each process is prevented from being combed manually, and the production plan arrangement efficiency is improved; meanwhile, because the data is calculated by the logic operation of the computer, if the initial data or other data needs to be updated, the data can still be updated quickly and accurately, and the influence on the production efficiency is avoided. For each process, on one hand, the raw material supply amount of the upstream process facing a plurality of downstream processes is determined, and raw materials with proper proportion can be distributed to the downstream processes according to the raw material supply capacity of the upstream process, on the other hand, the raw material demand amount of the downstream process is determined, the raw material demand amount of the downstream process facing the upstream processes is considered, the target planned yield of each process is determined by combining the raw material supply amount and the raw material demand amount and comprehensively considering the limitation between the supply capacity and the raw material demand, the accuracy of the target planned yield of each process can be further improved, the feeding direction of each process can be adjusted, and the execution efficiency of the feeding balance is improved.
Further, step S22, determining the raw material demand required to be received from the corresponding upstream process in the production cycle includes:
step S31, it is determined whether or not the downstream process in each supply group is provided with a node inventory.
In actual production, each process needs to have inventory, and the inventory has the function of avoiding influence on normal delivery when raw material supply is not timely or process equipment is failed to cause process suspension or emergency situations occur when emergency orders are added. The inventory is divided into node inventory and standard planning inventory, the priority of the node inventory is higher than that of the standard planning inventory, the node inventory is set for special conditions such as additional output, emergency order output and the like, and the standard planning inventory is set for emergency conditions such as untimely raw material supply or process suspension caused by process equipment failure and the like. The high inventory can improve the risk capability of the process for resisting shutdown, and the low inventory can reduce the capital occupation of enterprises. Therefore, inventory is necessary and as many as possible in a reasonable number.
When determining the material demand that needs to be provided to the upstream process in the downstream process, the demand of the stock needs to be considered, and when the process is provided with the node stock, the influence of the node stock on the material demand produced by the process needs to be considered preferentially, that is, step S32 is executed. When the process does not set the node inventory, only the influence of the standard planning inventory is considered, and step S33 is executed.
And step S32, if yes, determining the raw material demand quantity which needs to be received from the corresponding upstream process in the production period according to the original planned yield, the node inventory, the actual inventory and the preset adjustment period.
The original planned yield refers to the planned yield obtained by considering only the basic production demand and not considering the influence of the inventory. The actual inventory refers to the remaining inventory at the preset time of the production cycle, for example, if the production cycle is one day and the preset time is 0, the actual inventory is the remaining inventory at zero time per day. Because the inventory is an emergency storage resource, the inventory needs to be ensured to be sufficient, and when the inventory is consumed, the consumption needs to be compensated as soon as possible, namely the inventory is compensated within a preset adjustment period.
For example, the originally planned production of process B1 is 1000 tons. The node inventory is 800 tons, but the actual inventory is only 600 tons, and the inventory lacks a gap of 200 tons, and the 200 tons need to be replenished within three days (three days are the preset adjustment period), the 200 tons are shared to the production plan within 3 days, so that the yield of 67 tons needs to be increased every day, and at the moment, the raw material demand of the process B1 is 1067 tons.
And step S33, if not, determining the raw material demand required to be received from the corresponding upstream process in the production cycle according to the original planned output, the standard planned inventory, the actual inventory and the preset adjustment cycle.
The principle of step S33 is similar to that of step S32, and is not described here.
Step S32 or step S33 may be broken down into the following detailed steps (here, step S33 is taken as an example for explanation).
Step S33 specifically includes:
step S41, obtain original planned output, standard planned inventory, actual inventory, and preset adjustment periods.
Raw planned output, standard planned inventory, actual inventory, and preset adjustment periods are all directly available data.
Step S42, determining an additional planned output for adjusting the actual inventory to the standard planned inventory by the downstream process within a preset adjustment period according to the standard planned inventory, the actual inventory and the preset adjustment period.
The additional planned production needed to be added based on the original planned production can be determined according to the standard planned inventory, the actual inventory and the preset adjustment period. The additional planned output needs to meet a preset condition, that is, all additional planned outputs produced within a preset adjustment period can fill the actual inventory to the standard planned inventory at the end of the preset adjustment period.
Step S43 determines the raw material demand that the downstream process needs to receive from the corresponding upstream process in the production cycle, based on the original planned output and the additional planned output.
By adding the original planned output and the additional planned output, the raw material demand that the downstream process needs to receive from the corresponding upstream process in the production cycle can be determined.
Further, an optimization technical scheme is further provided on the basis of the technical scheme provided by the above:
in step S51, for the downstream processes in each supply group, when the number of corresponding upstream processes is plural, the raw material supply ratio between the plural upstream processes is determined.
The number of upstream processes corresponding to downstream processes in each supply group may be one or more. When the number of the corresponding upstream processes is 1, it is only necessary to directly supply the determined raw material demand to the corresponding upstream processes. When the number of the corresponding upstream processes is plural, it is necessary to determine how much demand the downstream processes should provide to each of the upstream processes, respectively. And how much demand the downstream process should provide to each upstream process is determined by the specific raw material supply ratio (the principle supply ratio can be determined according to the actual production situation).
For example, as shown in fig. 3, the downstream process B1 corresponds to an upstream process including a process a1, a process a2 and a process A3, and the raw material supply ratio of the process a1, the process a2 and the process A3 is 1:2: 3. In actual production, for the downstream process B1, the ratio of the upstream process supplies is generally distributed in such a way that the sum of the ratios is 1, that is, the sum of the ratios of the raw materials supplied by all the upstream processes to the downstream process B1 is recorded as 1, and then the raw material supply ratio of the process a1, the process a2 and the process A3 can be converted from 1:2:3 to 0.17:0.33: 0.5.
In step S52, a raw material demand component received by the downstream process from each of the plurality of upstream processes is determined based on the raw material supply ratio and the raw material demand.
The raw material demand is the total amount of the downstream process that should be received from all the upstream processes, and the raw material demand can be used to determine the raw material demand component corresponding to each upstream process according to the raw material supply ratio.
For example, as shown in fig. 3, if the raw material demand of the process B1 is 6000 tons, the raw material demand of the process a1, the process a2 and the process A3 are 1000 tons, 2000 tons and 3000 tons, respectively.
Further, step S23, determining the raw material supply amount required to be provided to the corresponding downstream process in the production cycle, specifically includes:
in step S61, for each upstream process in the supply group, when the number of corresponding downstream processes is plural, the target production amount of the upstream process is acquired, and the raw material demand amount of each of the plural downstream processes is acquired.
In step S62, a planned supply amount of raw material for the upstream process is determined based on the raw material demand for each of the plurality of downstream processes.
The number of downstream processes corresponding to upstream processes in each supply group may be one or more. When the number of the corresponding downstream processes is 1, all the products produced by the upstream process are conveyed to the downstream process for further processing, and when the number of the corresponding downstream processes is multiple, the products produced by the upstream process need to be distributed to the multiple downstream processes. And the specific amount of the downstream processes to be distributed is determined according to the raw material demand of each downstream process in the downstream processes. The sum of the raw material demand amounts of the plurality of downstream processes can be used as the planned raw material supply amount of the upstream process.
In step S63, when the planned supply amount of the raw material is equal to or greater than the target production amount, the target production amount is set as the supply amount of the raw material required by the upstream process to be supplied to the corresponding downstream process in the production cycle.
In step S64, when the planned supply amount of raw material is smaller than the target production amount, the planned supply amount of raw material is used as the supply amount of raw material required by the upstream process to be supplied to the corresponding downstream process in the production cycle.
In the case where the planned supply amount of the raw material is equal to or greater than the target production amount, that is, the planned supply amount of the raw material exceeds the maximum production amount in the production cycle, the planned supply amount of the raw material means that the planned supply amount of the raw material cannot be completed, and the target production amount is taken as the supply amount of the raw material in the upstream process. When the planned supply amount of the raw material is smaller than the target production amount, that is, the planned supply amount of the upstream process does not exceed the maximum production amount in the production cycle, the planned supply amount of the raw material is directly used as the supply amount of the raw material of the upstream process.
For example, referring to fig. 3, if the raw material demand amounts of process B1 and process B2 to process A3 are 1000 tons and 1200 tons, respectively, and the sum of the raw material demand amounts of the two downstream processes is 2200 tons, and the maximum value in the production cycle of process A3, i.e., the target production amount is 2000 tons, then process A3 actually does not complete the 2200 tons, and therefore, only 2000 tons can be used as the raw material supply amount of process A3. If the target production amount of the process A3 is 2300 tons, 2200 tons can be directly used as the raw material supply amount of the process A3.
More specifically, after determining the raw material supply amount of the upstream process, it is necessary to determine the raw material supply amount that the upstream process needs to provide to each downstream process, that is:
in step S71, for the upstream process in each supply group, when the number of the corresponding downstream processes is plural, the raw material demand ratio between the plural downstream processes is determined.
In step S72, a raw material supply amount to be supplied from the upstream process to each of the plurality of downstream processes is determined based on the raw material demand ratio and the raw material supply amount.
When the number of the downstream processes corresponding to the upstream process is plural, it is necessary to determine a raw material demand ratio according to the raw material demand of each downstream process, divide the raw material supply of the upstream process according to the raw material demand ratio, and further determine the raw material supply amount of each downstream process corresponding to the upstream process.
For example, referring to fig. 3, the process B1 corresponds to two downstream processes C1 and C2, the ratio of the raw material demand of the process C1 and the process C2 is 2:3, and the raw material supply amount of the process B1 is 3000 tons, then the raw material supply amount of the process B1 to the process C1 is 1200 tons, and the raw material supply amount of the process B1 to the process C2 is 1800 tons. In actual production, for the upstream process B1, the distribution ratio is generally determined to each downstream process in such a manner that the sum of the ratios is 1, that is, the sum of the ratios of the upstream process B1 distributing the raw materials to all the downstream processes is recorded as 1, and then the raw material demand ratio of the process C1 and the process C2 can be converted from 2:3 to 0.4: 0.6.
Further, for each process of the target production line, the products produced in each process are not all sent to the next process for further processing, for example, as shown in fig. 4, process A3 requires raw material supply to process B1 and process B2, and process A3 has a portion of the products sold directly for sale without further processing. In general, when the product produced by a process satisfies the processing demand and the inventory demand of the subsequent process and has a remaining production volume, the part of the product is directly sold as an outsourced product, and therefore, when the planned supply amount of the raw material is smaller than the target production volume and the target production volume is the supply amount of the raw material required by the upstream process to be supplied to the corresponding downstream process in the production cycle, the production volume other than the planned supply amount of the raw material in the target production volume is used as the outsourced filling production volume.
In summary, in the embodiment, the raw material demand of the process is adjusted according to the node inventory or the standard plan inventory set in the process, so that the accuracy of the target planned yield of each process can be effectively improved; for each process, on one hand, the raw material supply amount of the upstream process facing a plurality of downstream processes is determined, and raw materials with proper proportion can be distributed to the downstream processes according to the raw material supply capacity of the upstream process, on the other hand, the raw material demand amount of the downstream process is determined, the raw material demand amount of the downstream process facing the upstream processes is considered, the target planned yield of each process is determined by combining the raw material supply amount and the raw material demand amount and comprehensively considering the limitation between the supply capacity and the raw material demand, the accuracy of the target planned yield of each process can be further improved, the feeding direction of each process can be adjusted, and the execution efficiency of the feeding balance is improved.
