Example two:
the present invention also includes a method of implementing an advanced manufacturing process management system, in particular, comprising executing a first operational flow of an STDM system and executing a second operational flow of a PMTM system,
as shown in fig. 4, the first operational flow includes the following steps: :
(A) management execution criteria, shown as oval 700, which is the beginning of an execution criteria management flow, includes entering, viewing, editing, and/or deleting execution criteria information, etc., including but not limited to execution criteria name, number, version, release date, implementation date, standard file storage path, and associated other criteria, etc.; typically, the execution criteria information may be stored, for example, in a relational database table. As indicated at diamond 702, if the execution criteria does not have a standard file, the executable step (B) stores the standard file, and if the standard file already exists, determines whether to parse the file;
(B) the standard file is stored, as shown at block 704, which stores the standard file. It should be understood that the standard file is usually stored in PDF, Word or other format through a storage unit, such as storing path information of the standard file is stored in the execution standard information at the same time, based on which the standard file can be retrieved, downloaded or browsed online, etc.; typically, the standard file is stored in a computer file system, such as a disk or a cloud storage space. Determining whether to perform parsing as shown in diamond 706, if so, performing step (C), otherwise, returning to step (a);
(C) obtaining execution criteria information, as shown at block 708, it should be appreciated that the criteria file is typically published in an unstructured form suitable for human reading, and typically requires human parsing to make it a structured execution criteria accessible to the computer information system. Therefore, the parsing operation further includes the following steps based on the acquired execution standard information (including the standard file):
(D) resolving the product category, as indicated by diamond 710, and if it is determined to resolve the product category, then performing this step, as indicated by block 712, for resolving the product category in the standard file; otherwise, executing the next step. The product categories are generally classified according to key characteristics of the product, such as product type, material, condition, etc., for example, a precision copper tube may be of the coil type, a copper alloy material with alloy designation TP2 is used, and a copper tube in a hard condition is used. In fact, the product category is an identification of a combination of key characteristics of the product, such as may be described as "hard TP2 copper coil"; it should be understood that the product categories have hierarchical relationships, such as hard TP2 internal thread copper coil and hard TP2 plain copper coil are sub-categories of hard TP2 copper coil;
(E) parsing the process item, as shown at diamond 714, if it is determined that the process item is parsed, as shown at block 716, the step parses the process item from the standard file; otherwise, executing the next step. As previously mentioned, process items are process control points, such as outer diameter, wall thickness, ovality, etc. of precision copper tubing, which are typically present in a standard file in a human-readable, unstructured form. Step (F) may be performed based on the product category parsed in step (D) and the process item parsed in step (E);
(F) configuring and executing standard process items, as shown in a diamond 718, and executing the step when determining to configure and execute the standard bow chair items, as shown in a block 720, wherein standard process parameters are generally executed according to product key characteristic descriptions in a standard file, and the step configures the process items contained in the standard file one by one according to the analyzed product key characteristic combinations (namely product categories); otherwise, executing the next step. If the current standard is a new version of the original standard and no new or deleted items are added except for the change of the parameter value, the step (G) can be directly executed; otherwise, executing step (G) after the configuration information needs to be configured or adjusted;
(G) setting the execution standard process parameters, as indicated by diamond 722, and executing the step when determining to set the execution standard process parameters, as indicated by block 724, the step sets the parameters of the analyzed process parameters one by one according to the process items according to the execution standard and the configuration thereof; otherwise, the flow is ended. The process flow ends with no or completed execution of standard process parameter settings, as indicated by the oval 726.
Further, the execution criteria in the operational flow may be described as a software system model, which may include, but is not limited to, the following attributes:
TABLE 2 executive Standard Attribute Table
| 1 | Name (R) |
| 2 | Numbering |
| 3 | Version(s) |
| 4 | Date of release |
| 5 | Date of implementation |
| 6 | Standard document |
| 7 | Brief introduction to the drawings |
In practice, the execution criteria will tend to be associated with and by other execution criteria, and thus, the association between execution criteria may be expressed as a software system model that may include, but is not limited to, the following attributes:
TABLE 3 PERFORMATION STANDARD ASSOCIATION ATTRIBUTES TABLE
| 1 | Execution criteria |
| 2 | Association enforcement criteria |
| 3 | Association execution criteria type |
The product categories in the operational flow may be described as a software system model, which may include, but is not limited to, the following attributes:
TABLE 4 product Category Attribute Table
| 1 | Name (R) |
| 2 | English name |
| 3 | Code |
| 4 | Class of father |
| 5 | Key characteristics are |
| 6 | Key characteristic two |
| 7 | Key characteristics three |
| 8 | …… |
| 9 | Key characteristic N |
In reality, the process items of the execution standard may depend on other process items, for example, the range of the outer diameter deviation of the precision copper tube depends on the range of the outer diameter, and the range of the parameter values of the outer diameter is different accordingly, for example, the national standard GB/T17791 and 2007 stipulates that the range of the outer diameter is ± 0.05mm when the range of the outer diameter is > 15-20 mm, and the range of the outer diameter deviation is ± 0.07mm when the range of the outer diameter is > 20-30 mm; it should be understood that sometimes one process item may depend on a plurality of other process items, such as the artificial standard defect hole diameter range in the aforementioned national standard depends on both the pipe outer diameter range and the pipe wall thickness range. Furthermore, the parameter values or ranges of parameter values for a process item may depend on certain applicable conditions (commonly referred to as standards), such as the rate of flaring of copper tubing, with a 45 ° flare than a 60 ° flare. Thus, when describing using a software system model, some conventions are typically followed: the defined applicable condition (i.e., standard) can be defined as an attribute of the model when not dependent on other process items; the correlation model can be defined in dependence upon one or more other process items. Based on this convention, the process item may be described as a software system model that may include, but is not limited to, the following attributes:
TABLE 5 Process item Attribute Table
As mentioned above, the dependencies of the process items are typically involved in performing the standard process item configuration, and thus, the standard process item configuration may be described as an associated model when described as a software system model, which may include, but is not limited to, the following attributes:
TABLE 6 PERFORMATION STANDARD PROCESS CONFIGURATION ATTRIBUTES TABLE
| 1 | Class of execution criteria | The same standard belonging to one category, e.g. different versions |
| 2 | Type (B) | Such as dimensional measurements, chemical compositions, process properties, etc |

| 4 | Process item | Such as deviation of outer diameter |
| 5 | Associated itemEyes of a user | Such as the outside diameter |
| 6 | Type of association | Such as ranges, averages or other custom types, etc |
The execution criteria process parameters may be described as a software system model that may include, but is not limited to, the following attributes:
TABLE 7 PERFORMATION STANDARD PROCESS PARAMETER ATTRIBUTES TABLE
| 1 | Execution criteria | Execution criteria to which the parameter belongs |
| 2 | Standard configuration item | Execution standard process configuration item to which process parameter belongs |

| 6 | Associating item values | Value of executing standard process project association |
| 7 | Associated item minimum | Minimum value for executing standard process project associated project |
| 8 | Maximum value of associated item | Maximum value of associated items of executing standard process items |
It should be understood that one skilled in the art can flexibly define the relevant models as needed and desired, and that the models disclosed in this example can be augmented, reduced, or further refined, such as the data type of the model attributes and whether they can be empty, and so forth. Those skilled in the art may write specific processing logic, such as processing logic that implements the associated type of standard process project configuration, etc., according to the specific application scenario and needs.
As shown in fig. 5, the second operation flow includes the following steps:
(H) managing the product, as represented by oval 600, which is the beginning of the product manufacturing process management flow, which includes entering, viewing, editing, and/or deleting product information, etc.; the product information comprises product names, categories, specifications, applicable process flows and other product key characteristics needing to be managed and the like;
(I) managing product categories, as indicated by diamond 602, determining whether there are suitable product categories, and if there are not suitable product categories, performing this step, as indicated by block 604, as set forth in example two, where a product category is an identification of a key feature combination of a product, this step operation includes operations such as adding, editing, and deleting product categories; otherwise, executing the next step;
(J) managing the process flow, as indicated by diamond 606, to determine if there is a suitable process flow, and if there is a lack of a suitable process flow, performing this step, as indicated by block 608, which is modeling the product manufacturing flow, i.e., as a series of ordered processing nodes (commonly referred to as a sequence in a flow-type manufacturing model); otherwise, executing the next step. The completed product manufacturing process management is based on product information and product process flow and is based on process items, as shown in diamond 610, and step (K) may be performed if there are no suitable product process items available;
(K) managing the process items, as shown in diamond 610, determining whether there are suitable process items, if there are not suitable process items, executing the step, otherwise executing the next step; as shown in block 612, as set forth in the second embodiment, the process item is a process control point, and in practice, the manufacturing process of the product is generally managed according to the manufacturing node and the type, for example, the manufacturing process of the precision copper tube is organized according to the procedure, the product characteristics, the manufacturing manner, and the like, and includes many aspects such as dimension control, mechanical performance, tooling mold, lubrication, detection, and the like;
(L) configuring the product manufacturing process item, as indicated by diamond 614, confirming whether the product manufacturing process item is configured, performing this step if configuration is determined, otherwise performing the next step; this step implements product manufacturing process item configuration, as shown at block 616, it being understood that in a plant with product diversity, a certain class of products typically have the same manufacturing process flow and process control points, and thus, for ease of management, may be configured by product class when configuring product manufacturing process items, as described in the previous step, product manufacturing process items are typically configured on a process-by-process basis by a class such as product control size, mechanical properties, tooling mold, equipment operating parameters (e.g., pull speed), lubrication, cleaning, inspection, and operating methods, etc.; therefore, the process management efficiency can be remarkably improved and the working intensity of process management personnel can be reduced by managing the product manufacturing process parameters based on the product manufacturing process configuration project. A further step in which a compliance check configuration may be conducted, the compliance check configuration including a compliance check process item and compliance check logic;
(M) set product manufacturing process parameters, as indicated by diamond 618, confirm whether product manufacturing process parameters are set, confirm the settings to perform this step, otherwise end the product process management flow. This step configures the parameters of all process items one by one based on the product information and the product manufacturing process item configuration, as shown in block 620. It should be appreciated that in setting parameters for a product process item, a compliance check is required if the process item has a compliance check configuration, and success can be set only if the process parameters meet the compliance check. As indicated by oval 622, the operational flow ends with no product manufacturing process parameter settings or with the settings completed.
Further, a compliance check of the product manufacturing process parameters is implemented in step (M), and fig. 6 shows an execution flow of the compliance check, which includes the following steps:
(N) the product manufacturing process item is obtained, as shown by oval 800, which is the beginning of the compliance check flow. It should be understood that the acquired process item is acquired from a product manufacturing process item configuration, and the process item contains product information to which the process item belongs;
(O) setting product manufacturing process project parameters, as shown in block 802;
(P) determining whether the process item is subject to a compliance check, as indicated by diamond 804, based on a compliance check configuration of the product manufacturing process item configuration, and if the compliance check is not to be performed, performing step (S) of storing the product manufacturing process item parameters, and if the compliance check is to be performed, performing step (Q);
(Q) load process project compliance checking logic, as shown at block 806, from the product manufacturing process project configuration, which logic can be implemented and stored using DLLs (dynamic Link libraries) or other script files (e.g., JavaScript, Ruby, etc.), if desired;
(R) performing a compliance check, as shown in block 808, which may be implemented by one skilled in the art according to the actual situation, a method of compliance check is described here as an example: and (3) requesting the execution standard parameters of the current project from the execution standard management system according to the product information (including the product category information), judging based on the acquired information and the parameters set by the current project, if the parameters set by the current process project meet, returning to pass, otherwise, returning to fail, as shown in diamond 810, if the parameters do not pass, returning to the step (O) to reset the parameters of the product manufacturing process project, and if the parameters pass, executing the next step. It should be understood that the decision operation in the compliance checking method depends on the specific application scenario.
(S) store product manufacturing process project parameters, as indicated by oval 812, which confirms the product manufacturing process project parameters, stores the set process parameters and ends the compliance check operation flow.
Further, the product described in the operational flow may be described as a software system model, which may include, but is not limited to, the following attributes:
