With the development of technology, in modern Manufacturing factories, Manufacturing Execution Systems (MES) are usually constructed to optimally manage the entire production process from order placement to product completion through information transfer. In manufacturing plants, because the manufacturing process for the product is often complex, equipment constraints are established for each piece of equipment in the MES system to make the production of the equipment meet the regulatory requirements. Wherein each device constraint comprises at least one constraint condition; each equipment constraint is used to allow or prohibit the target equipment from producing the product batch when the product batch meets each constraint included in the equipment constraint. Taking a semiconductor plant as an example, there are on average about 500 equipment constraints per equipment in the MES system, with as few as one, and as many as tens of constraints per equipment constraint. In the production process, the MES system needs to count the product quantity of each product batch produced by the target equipment under the constraint of each equipment so as to realize the information management of the production process.
Research shows that with the advance of the production process, the constraint conditions under the constraint of the equipment can be changed frequently due to various reasons such as equipment upgrading, version updating, production debugging and the like. The existing product quantity statistical method can not change the statistical value according to the change of the constraint condition, so that the MES system makes the statistics of the product quantity wrong, and the statistics is lost; the other quantity statistical method sets respective statistical values for each constraint condition, so that a large amount of repeated statistical data exist in the MES system, a large amount of storage and calculation resources are occupied, and the statistical efficiency is low. Therefore, the existing statistical method for the product quantity in the production process cannot meet the requirements of production and management.

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. Every other embodiment that can be obtained by a person skilled in the art without making creative efforts based on the embodiments of the present application falls within the protection scope of the present application.
With the development of technology, in modern Manufacturing factories, Manufacturing Execution Systems (MES) are usually constructed to optimally manage the entire production process from order placement to product completion through information transfer. In manufacturing plants, because the manufacturing process for the product is often complex, equipment constraints are established for each piece of equipment in the MES system to make the production of the equipment meet the regulatory requirements. Wherein each device constraint comprises at least one constraint condition; each equipment constraint is used to allow or prohibit the target equipment from producing the product batch when the product batch meets each constraint included in the equipment constraint. During the production process, the MES system needs to count the product quantity of each product batch produced by the equipment under the constraint of each equipment so as to realize the information management of the production process.
Research shows that with the advance of the production process, the constraint conditions under the constraint of the equipment can be changed frequently due to various reasons such as equipment upgrading, version updating, production debugging and the like. The existing product quantity statistical method can not change the statistical value according to the change of the constraint condition, so that the MES system makes the statistics of the product quantity wrong, and the statistics is lost; the other quantity statistical method sets a statistical value for each constraint condition, so that a large amount of repeated statistical data exists in the MES system, a large amount of storage and calculation resources are occupied, and the statistical efficiency is low.
Therefore, the existing statistical method for the product quantity in the production process cannot meet the requirements of production and management.
Based on this, the embodiment of the application provides a product quantity statistical method and a product quantity statistical device in a production process, which can determine whether a new counting key needs to be generated or not by comparing constraint conditions under the equipment constraint before and after the change when the equipment constraint occurs, and record the product quantity in a counting value corresponding to the new counting key after the occurrence condition is changed; therefore, the quantity counting efficiency can be improved, and the problems of product quantity counting errors and counting loss when the equipment constraint changes are solved.
Referring to fig. 1, fig. 1 is a flowchart illustrating a product quantity statistical method according to an embodiment of the present disclosure. As shown in fig. 1, the product quantity statistical method provided in the embodiment of the present application includes:
s101, aiming at any first constraint condition changed in the target equipment constraint with changed conditions, determining whether a second constraint condition corresponding to the first constraint condition exists.
Wherein the first constraint condition is obtained after the second constraint condition is changed; the target device constraints are used to allow or prohibit the target device from producing any product lot when the product lot satisfies each constraint included in the target device constraints.
It should be noted that each equipment in the MES system includes at least one equipment constraint, each equipment constraint includes at least one constraint condition, and when a certain product batch satisfies each constraint condition under a certain equipment constraint, it is determined that the product batch satisfies the equipment constraint; if the equipment constraint is a forward equipment constraint, allowing the target equipment to produce the product batch; if the equipment constraint is a negative equipment constraint, the target equipment is prohibited from producing the product batch.
Each constraint condition comprises a product parameter and a value range of the product parameter; the product parameter includes at least one of: processes, working procedures, product manufacturing procedures, formulas, data acquisition plans and customer information; for example, the constraint may be "procedure 1 or 2" and "recipe K".
In one possible implementation, as the production process advances, conditional changes to target equipment constraints are required for many reasons, such as equipment upgrades, version updates, production commissioning, etc. At this time, the user may change the conditions of the target device constraints through the setting interface of the device constraints, for example, modify the parameter value range of any constraint condition in the target device constraints, add a new constraint condition in the target device constraints, or delete the original constraint condition in the target device constraints. After the user completes the setting, the modified constraint conditions can be saved in the MES system by clicking a 'save' or 'confirm' control so as to complete the change of the equipment constraint. The MES system can automatically determine whether the target equipment constraint has changed conditions, which constraint conditions in the target equipment constraint have changed, and obtain information such as a second constraint condition before change corresponding to the first constraint condition after each change by comparing the data of the target equipment constraint and the like.
In this step, it should be noted that the product parameters in the first constraint after the change and the second constraint before the change corresponding to the first constraint after the change are the same; that is to say, in the embodiment of the present application, only the parameter value range in a certain constraint condition is changed for the change of the constraint condition, and exemplarily, the "procedure of 1 or 2" of the constraint condition is modified to "procedure of 3"; if the second constraint condition corresponding to the first constraint condition does not exist, the product parameter in the first constraint condition is changed, for example, the constraint condition 'procedure is 1 or 2' is modified to 'formula is K', which is actually equivalent to deleting the original constraint condition and creating a new constraint condition; for another example, if a constraint condition "recipe is K" is added, it means that the constraint condition is not set for the product parameter "recipe" under the constraint of the target device before the condition is changed.
S102, if a second constraint condition corresponding to the first constraint condition exists, comparing the first constraint condition with the second constraint condition, and determining whether the first constraint condition meets a preset change condition.
In one possible implementation, step S102 may include the following steps:
and S1021, determining whether the first value range of the first constraint condition can completely comprise the second value range of the second constraint condition.
S1022, if the first value range cannot completely include the second value range, determining that the first constraint condition satisfies the predetermined change condition.
In a possible implementation manner, it is determined whether the first value range can completely include the second value range by comparing the first value range of the first constraint condition with the second value range of the second constraint condition. For example, if the constraint condition "procedure is 1" is modified to "procedure is 2", the first value range is 2, the second value range is 1, and at this time, the first value range cannot completely include the second value range; for another example, if the constraint condition "procedure is K or E" is modified to "procedure is K", the first value range is K, and the second value range is K or E, and at this time, the first value range cannot completely include the second value range. That is to say, the phrase "the first value range cannot completely include the second value range" in the embodiment of the present application includes: the first value range does not include the second value range at all and the first value range can only include a portion of the second value range.
S1022, if the first value range cannot completely include the second value range, determining that the first constraint condition satisfies the predetermined change condition.
S103, if at least one first constraint condition meeting the preset change condition exists in the target equipment constraint, setting a new counting key for the target equipment constraint.
Wherein, the counting key and the target device constraint respectively have an association relationship, and the counting key and at least one counting value respectively have an association relationship; the count key is a unique serial number that indexes the count value for the target device constraint; and each counting value has an association relationship with one product batch and is used for recording the product quantity of the product batch produced by the target equipment under the constraint of the target equipment.
In this step, if there are a plurality of first constraints in the target device constraint and there is at least one first constraint satisfying the predetermined change condition, a new count key is set for the target device constraint. The setting method of the count key may be time plus serial number, such as 20211221007, to ensure that the count key is a unique serial number under the constraint of the target device.
In one possible embodiment, the association relationship between the count key and the target device constraint may be established by a data structure of a data table; the counting key (key) and the at least one counting value (value) form a key value pair, so that the at least one counting value can be indexed through the counting key; when the product quantity of a certain product batch is recorded in the count value, the batch number of the product batch can be recorded in the data table at the same time, so as to establish the association relationship between each count value and the product batch corresponding to the count value.
In specific implementation, when a certain product batch is to be put into the target equipment for production, the MES system first determines whether the target equipment can produce the product batch according to all equipment constraints under the target equipment; specifically, it may be arranged to allow the target equipment to produce the product lot if the product lot satisfies at least one forward equipment constraint and does not satisfy all reverse equipment constraints. Recording the batch number of the product batch in the process of producing the product of the product batch by the target equipment; meanwhile, each equipment constraint of the target equipment in the MES system is provided with a corresponding counting key, and each counting key is respectively associated with at least one counting value. For each equipment constraint satisfied by the product batch, when the target equipment produces the product of the product batch, the number of the product batch produced by the target equipment under the equipment constraint is recorded by the counting value.
S104, determining at least one new count value associated with the new count key, and continuously recording the product quantity of the product batch corresponding to the new count value after the condition change occurs in each new count value.
In a possible implementation, the determining at least one new count value associated with the new count key in step S104 includes:
s1041, determining whether each product batch produced by the target device under the constraint of the target device before the condition change meets each first constraint condition.
S1042, determining the product batch meeting each first constraint condition as a target product batch.
S1043, determining, for each target product batch, a count value associated with the target product batch before the condition change occurs.
S1044, determining the count value as a new count value associated with the new count key.
When the condition is changed, the product lot originally capable of being produced under the target equipment constraint may not meet the production requirement of the equipment constraint after the condition is changed. At this time, it is necessary to determine whether each product lot produced by the target device under the constraint of the target device before the condition change meets the constraint of the target device after the condition change, that is, whether each first constraint condition is met.
In one possible embodiment, it may be determined whether the product lot satisfies each of the first constraints by:
step 1, obtaining batch information of the product batch.
In one possible embodiment, during the process of producing the product of the product batch by the target device, the batch number of the product batch is recorded; the batch information of the product batch can be found through the batch number.
The batch information comprises at least one product parameter and the value of each product parameter;
and 2, aiming at each first constraint condition, searching a first product parameter in the first constraint condition and a value of the first product parameter in the batch information.
And 3, if the value of the first product parameter in the batch information falls into a first value range in the first constraint condition, determining that the product batch meets the first constraint condition.
Illustratively, if a certain first constraint condition "procedure" is 1 or 2 ", a first product parameter" procedure "is searched in the batch information; if the batch information includes information of "procedure ═ 1", it is described that the value of the first product parameter falls within the first value range in the first constraint condition, and it is determined that the product batch meets the first constraint condition.
Further, if the product batch meets each first constraint condition, determining the product batch as a target product batch; for each target product batch, determining an original count value associated with the target product batch before the condition change occurs, and inheriting the original count value into a new count value associated with a new count key to continue counting the number of products of the product batch.
Illustratively, the first constraint in the target equipment constraint after the condition change is "process is a". The corresponding second constraint condition is that the process is A or B, the batch information of a certain product batch a comprises the process is A, and the original count value corresponding to the product batch a is 50; then, after the condition is changed, inheriting the original count value 50 corresponding to the product batch a into a new count value, and continuously counting the product quantity of the product batch a from 50 by the new count value.
In one possible embodiment, the step S104 of continuously recording the product quantity of the product batch corresponding to the new count value after the condition change occurs in each new count value includes:
s1045, determining whether the target product batch comprises the product batch to be counted.
S1046, if the target product batch comprises the product batch to be counted, continuously recording the product quantity of the product batch to be counted in a new counting value associated with the product batch to be counted.
S1047, if the target product batch does not include the product batch to be counted, newly establishing a new counting value and establishing the association relationship between the new counting value and the new counting key and between the new counting value and the product batch to be counted.
S1048, recording the product quantity of the product batch to be counted in the newly-built counting value; wherein, the initial value of the newly-built counting value is a set value.
In one possible embodiment, when the target device is ready to produce a certain product batch after determining that the certain product batch meets the changed target device constraint, the number of products produced by the certain product batch to be counted under the target device constraint needs to be counted.
First, determining whether the product lot to be counted is the target product lot (i.e., the product lot to be counted is a product lot that has been produced under the constraint of the target device before the condition change, and the target device can still count the product lot after the condition change); if the product batch to be counted is the target product batch, determining a counting value corresponding to the product batch to be counted to continue counting according to the association relationship between the counting value and the product batch; if the product batch to be counted is not the target product batch, indicating that the target device does not produce the product batch under the constraint of the target device, at this time, a new count value needs to be newly established, and an association relationship between the new count value and the new count key and between the new count value and the product batch to be counted is established; optionally, the set value is preset by a user according to production needs, for example, the set value may be 0, and then the product quantity of the product batch to be counted is counted from 0 in the newly-created count value.
In a possible embodiment, said constraint also comprises a product quantity limit; the product quantity statistical method further comprises the following steps:
when the target device produces any product batch under the constraint of the target device, if the sum of the count values indexed by the count key corresponding to the constraint of the target device exceeds the product quantity limit, the target device is prohibited from continuing to produce the product batch.
It should be noted that in some scenarios of industrial production, a small amount of products are often produced for testing or verification; in this case, the constraint may also include a product quantity limit, and the target equipment may be constrained by "a product with a formula of K, and the production quantity is less than 100 sheets". If the first product lot, the second product lot, and the third product lot all satisfy the target equipment constraint; the target device is constrained by the target device to produce the first product batch for 50 pieces, produce the second product batch for 30 pieces, and produce the third product batch for 20 pieces, and if the target device continues to produce under the constraint of the target device, the sum of the count values will exceed the product quantity limit for 100 pieces, so the target device is prohibited from continuing to produce the first product batch, the second product batch, and the third product batch.
Further, when the target device constraint changes the condition, the limit of the number of products in the constraint condition may also be changed, and corresponding to the above example, the constraint condition is modified to "the product with formula K and the number of produced products is less than 150", in which case, it is also not necessary to set a new count key, and the counting is continued in the count value associated with the original count key.
In a possible embodiment, if it is determined in step S101 that there is no second constraint condition corresponding to the first constraint condition, which indicates that the target device constraint does not limit the value range of the first product parameter included in the first constraint condition before the condition is changed to form the constraint condition, for example, the first constraint condition is "recipe K", and the target device constraint does not limit the product parameter of "recipe" before the condition is changed, the target device constraint may restrict the batch information of each product batch produced before the condition is changed to have multiple values with respect to the product parameter of "recipe"; after the condition is changed, a new count key may also be set for the target device constraint, the product batch meeting each of the first constraint conditions is determined as a target product batch, and the original count value associated with the target product batch is determined as a new count value to continue counting the number of products, for which, the specific implementation manner may be referred to the foregoing, and is not described herein again; corresponding to the foregoing example, this time corresponds to screening out a target product batch with a product parameter "K" of the batch information, which is "recipe", from each product batch produced before the condition is changed, and inheriting the count value of the target product batch.
According to the product quantity statistical method in the production process, whether a second constraint condition corresponding to a first constraint condition exists or not is determined according to any first constraint condition changed in the target equipment constraint with changed conditions; wherein the first constraint condition is obtained after the second constraint condition is changed; the target equipment constraint is used for allowing or forbidding the target equipment to produce the product batch when any product batch meets each constraint condition included by the target equipment constraint; if a second constraint condition corresponding to the first constraint condition exists, comparing the first constraint condition with the second constraint condition, and determining whether the first constraint condition meets a preset change condition; if at least one first constraint condition meeting the preset change condition exists in the target equipment constraint, setting a new counting key for the target equipment constraint; wherein, the counting key and the target device constraint respectively have an association relationship, and the counting key and at least one counting value respectively have an association relationship; the count key is a unique serial number that indexes the count value for the target device constraint; each counting value has an association relationship with one product batch and is used for recording the product quantity of the product batch produced by the target equipment under the constraint of the target equipment; and determining at least one new counting value associated with the new counting key, and continuously recording the product quantity of the product batch corresponding to the new counting value after the condition change occurs in each new counting value.
By the method, when the equipment constraint occurrence condition is changed, whether a new counting key needs to be generated or not is determined by comparing constraint conditions under the equipment constraint before and after the change, and the product quantity is recorded in the counting value corresponding to the new counting key after the condition change occurs; therefore, the quantity counting efficiency can be improved, and the problems of product quantity counting errors and counting loss when the equipment constraint changes are solved.
