Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

The following describes a product data tracing method and system based on an information system according to an embodiment of the present application with reference to the drawings. First, a product data tracing method based on an information system according to an embodiment of the present application will be described with reference to the accompanying drawings.

Fig. 1 is a flowchart of a product data tracing method based on an information system according to an embodiment of the present application, and as shown in fig. 1, the method includes the following steps:

step 101, connecting the structure trees in multiple stages of product development, and communicating a function baseline, a distribution baseline and a product baseline in the technical state management of the product, wherein the multiple stages comprise a design stage, a process stage and a production stage.

The multiple stages can include various links in the product development process such as design, process, production preparation, manufacturing and plan management, the structure trees in the various stages related to product data tracing can be connected, and the specific related stages are not limited herein. The structure tree is a data model describing a data structure in a tree manner, and in the embodiment of the present application, the structure tree in each stage may include: three-dimensional design models, bill of Material (bom) trees of various types, process structure trees, production plan trees, and so on.

The technical state of the product refers to physical and functional characteristics specified in a technical document and achieved in the product, and the technical state management of the product refers to various types of means, such as technical and administrative management, for performing various types of management activities on the technical state of the product, including identification, control, auditing, remembering and the like. The base line in the technical state management is an initial plan formed by any configuration item after the configuration item passes through formal review and enters a controlled state at different time points of product development, for example, the distribution base line refers to a requirement specification which is formally reviewed and approved at the end of a requirement analysis stage, namely the distribution base line is an initially approved distribution configuration identifier.

In the embodiment of the application, related structure trees distributed in each stage in each information system corresponding to a product are connected in series in different forms, and then an implementation bom tree and an implementation route tree generated in the manufacturing process are added, so that the connection of the structure trees in a plurality of stages is realized, and the whole process from a function baseline to a distribution baseline and then to a product baseline in the technical state management is completed.

As an example, in order to more clearly describe a specific implementation process of the present application for implementing connection and communication of baselines of the structure trees, a specific method for performing different-form series connection on the structure trees in multiple stages of product development provided by an embodiment of the present application is described below, and fig. 2 is a schematic flow chart of the specific method for performing different-form series connection on the structure trees in multiple stages of product development provided by the embodiment of the present application, as shown in fig. 2, the method includes the following steps:

step 201, designing a three-dimensional model of the product to generate a three-dimensional model tree of the product.

Specifically, a product three-dimensional model is designed in a product data management system through design application, for example, CAD software, and after the design is completed, a three-dimensional model tree of the product, that is, an Engineering bill of materials (Engineering BoM, abbreviated as EBOM) of the structure of the product, is automatically generated in the product data management system.

And step 202, after supplementing the drawing-free parts and the main data attributes in the three-dimensional model tree, carrying out design file examination and signing to generate a design bill of materials DBOM of the product.

The non-drawing component is a component without a view of parts, such as an auxiliary material, and the attribute of the main data may be a related attribute of the main data applied by a user in the main data system.

Specifically, in this embodiment, after the three-dimensional model tree is supplemented with the non-image parts such as the auxiliary materials, the related attributes of the main data applied in the main data system are supplemented, the Design document approval process is initiated, the Design manufacturability review is performed by the related personnel such as the process personnel, and after the process meeting is completed, the Design bill of materials (Design BoM, DBOM for short) of the product is formed through approval.

Step 203, compiling a process bill of materials (PBOM), determining process routes and material information of parts of the product, and initiating a process route and material rating approval process.

Specifically, after the Process is qualified, a Process bill of materials (Process BoM, PBOM for short) may be compiled, and information such as a Process route and materials of the component part may be determined, for example, the determined information may specifically include: the method comprises the steps of self-making outsourcing, whether the materials are fed internally, a main pipe unit, a main manufacturing unit, blank types, outsourcing or outsourcing manufacturers of blanks, blanking sizes, the number of the producible products, single-piece process quota and the like.

And, after the product design approval process in step 202 is completed, a process route and material rating approval process may be initiated.

In an embodiment of the present application, after the PBOM is controlled, the PBOM can be synchronized to the enterprise resource management system and the manufacturing execution system, and the determined material information and the structure of the PBOM are synchronized to the enterprise resource management system and the manufacturing execution system.

Step 204, planning a manufacturing process route, allocating manufacturing resources, and compiling a structuring process used by the manufacturing execution system.

Specifically, after the process route and the material rating approval are completed, a manufacturing process route can be planned, resources can be reallocated, and a check point can be set. Then, the structured processes used by the manufacturing execution system are compiled according to preset compiling criteria and methods, for example, the processes available for the downstream manufacturing execution system are compiled according to the structured process compiling method according to the principle of one step, one graph and one card and one inspection. Wherein, the structured process of weaving can include but is not limited to: the method comprises the following steps of process route, operation steps, process drawings, detection parameters, check points, loading part distribution, process resource distribution and the like, so that a process structure tree is generated by a structural drawing compiling method and is issued to a manufacturing execution system along with a structured process.

And step 205, combining the process sent by the product data management system and the production order sent by the enterprise resource management system to produce the product, and summarizing the production and processing information of the product after the production is finished so as to generate a bill of material (BOM) for the product.

Specifically, the process issued by the received product data management system and the production order issued by the enterprise resource management system are bound in the manufacturing execution system, and the product production is started. After production is finished, according to actual generation operation, information of actual production and processing of the product is summarized to form the actual BOM of the product.

Therefore, the method carries out subsequent structure tree compiling in other related systems based on the structure tree generated in one system, realizes the series connection of different forms of the structure tree, and connects the structure trees in a plurality of stages. Through data synchronization and transmission among all information systems, the whole process communication of a function baseline, a distribution baseline and a product baseline in technical state management is realized. Therefore, data tracing paths among systems such as a product data management system, an enterprise resource management system, a manufacturing execution system and the like are opened, and effective tracing of data of each stage such as design, process, product and the like is facilitated.

Step 102, integrating a plurality of information systems corresponding to the product, and performing forward tracing on the technical state of the product, wherein the plurality of information systems comprise a product data management system, an enterprise resource management system and a manufacturing execution system.

Specifically, the product data management system may be integrated with an enterprise resource management system, or the product data management system may be integrated with a manufacturing execution system, and forward query is performed in the product data management system from a product entity to a process to a designed technical state.

In one embodiment of the present application, the forward tracing of the technical state of the product may include the following exemplary ways:

as a first example, a phase flag is set to a design file of a product, and tracing is performed by the phase flag when design data is changed. Specifically, the phase mark is added to the design file of the product, and when the design data changes, such as the change of the design data or the transition of the design data, the design data can be traced back through the phase mark version preset in the design file.

As a second example, different versions of the process file are determined, and the process is traced through the process file of the current version. Specifically, version management is performed on the design file, so that not only can the version be traced when the design data is changed, but also the process can be traced. For example, for the processes associated with different versions in the same stage of the product, the process file corresponding to the current version can be checked by selecting the design files of different versions. For the process tracing of different product stages, the corresponding process file of the current stage can be checked by selecting the product of the specified stage.

As a third example, the manufactured product information returned by the enterprise resource management system is acquired from the first query information sent to the enterprise resource management system integrated in advance. The first query information may be data encoding information, and specifically, the first query information is integrated with the enterprise resource management system in advance, and sends the main data encoding information to the enterprise resource management system in the product data management system to query the status information of the manufactured product, that is, the product in stock, on the way (outsourcing shopping) of the material returned by the enterprise resource management system. In addition, in-transit materials returned by the enterprise resource management system, namely various materials which are acquired through outsourcing or outsourcing and are not accepted and put in storage can be acquired.

As a fourth example, the second query message is sent to a manufacturing execution system which is integrated in advance, and the information of the work in process returned by the manufacturing execution system is obtained. The second query information may be information such as a pattern or a code of a material or a product, and specifically, the second query information is integrated with the manufacturing execution system in advance, the pattern code information of the material or the product to be manufactured is sent to the manufacturing execution system in the product data management system, and the information of the material in-process state returned by the manufacturing execution system is further queried and displayed to the user.

Therefore, the forward tracing from the design file to the process file to the design and manufacturing process of the production batch and the physical product is realized.

And 103, taking the execution process of the production plan as a tracing route, and reversely tracing the quality of the product through product pedigree tracing based on the tracing relation between the raw materials and the product.

Specifically, when the quality of the product is reversely traced, the production plan order can be used as a main route, the manufacturing execution system can receive the product from the production plan and store the relevant data of the product production such as the quality information in the whole process until the production plan is finished, and according to the quality information in the whole process executed by the production plan stored in the manufacturing execution system, when the quality of the product has a problem, the production plan execution process can be used as a tracing route for product quality tracing, namely, the quality data and the maintenance record of the product in the production process are traced.

It should be noted that, in the embodiment of the present application, the pedigree tracing is established on the retroactive relationship between the raw materials and the products, and based on the retroactive relationship between the finished products and the raw materials of the products, the raw material profile used by the generation equipment can be determined through the pedigree tracing. In a specific implementation, in an embodiment of the present application, batch numbers of raw materials and finished products may be preset, and a traceability relationship between the raw materials and the products is established through the batch numbers.

It should be noted that, since the production equipment is usually operated by the engine, in one embodiment of the present application, the output of the quality report sheet can be performed according to the engine number, and the component file used by each engine is established through pedigree tracking management, so that the unique identification of the related material batch or the used component can be conveniently found after the problem is found. In this embodiment, the product pedigree tracing comprises tracing the parts according to the engine and tracing the engine according to the parts, and reversely tracing the quality of the product through the product pedigree tracing, and comprises reversely tracing the product number according to the currently determined product problem by combining two product pedigree tracing modes of tracing the parts according to the engine and tracing the engine according to the parts.

Specifically, in this example, the flow of the engine tracing the parts is: the flow of the part tracing engine comprises the following steps: "supplier number-part lot number-product archive- > order number- > product number", and realize that the reverse retrospection of product quality combines the flow of two above-mentioned pedigree pursuits modes, and specific flow is: "find specific product problem- > engine trace back part- > supplier number- > supplier survey- > supplier number- > part trace back engine- > problem product number".

Therefore, the data tracing function development among the systems is carried out on the data in each system according to the technical state management idea, the reverse tracing from product objects to process and design is realized, and the reliability of the data tracing in each stage is further improved.

To sum up, the product data tracing method based on the information system of the embodiment of the application connects the structure trees in multiple stages of product development at first, communicates the function base line, the distribution base line and the product base line in the technical state management of the product, then integrates and sets up a plurality of information systems corresponding to the product, carries out forward tracing to the technical state of the product, then uses the production plan execution process as a tracing route, and carries out reverse tracing to the quality of the product through product pedigree tracing based on the tracing relation between the raw material and the product. Therefore, the method develops the data tracing function between systems corresponding to the product according to the technical state management thought, gets through the data tracing path between information systems of the products such as a product data management system, an enterprise resource management system, a manufacturing execution system and the like, is convenient for realizing the tracing from the design file to the process file to the design and manufacturing process of production batches and physical products, and particularly realizes the forward query and the reverse tracing of the technical state and quality histories of the products from physical products to various stages of process, design and the like, thereby ensuring that the data of each stage can be effectively traced, improving the convenience and the accuracy of tracing various product data and improving the efficiency of tracing the product data.

In order to more clearly describe the product data tracing method based on the information system in the embodiment of the present application, a detailed description is given below with respect to a specific embodiment of product data tracing based on the information system.

In this embodiment, a product data management architecture is first established based on the association of multiple information systems, fig. 3 is a schematic diagram of a specific product data management architecture combining multiple information systems provided in the embodiment of the present application, and as shown in fig. 3, the product data management architecture includes product development systems UG and TC, a resource planning system SAP, a production information management system MES, and a data acquisition and monitoring control system SCADA, where structure trees included in the systems and information included in the structure trees are shown in fig. 3, and are not described here again. In the manner shown in fig. 3, besides the functional structure tree and the distribution base line of the technical status management, the related structure trees (for example, the three-dimensional model, the design bom tree, the process bom, the process structure tree, the production plan tree, and the like included in fig. 3) distributed in each information system at each stage of design, process, production preparation, and the like are connected in series in different forms, and the real bom tree and the real route tree generated in the manufacturing process are added, so that the whole process from the functional base line to the distribution base line and then to the product base line in the technical status management is completed.

When the method is specifically executed, the method can comprise the following steps:

firstly, a designer opens CAD software from a product data management system to design a three-dimensional model of a product, and the product three-dimensional model tree, also called a structure EBOM, is automatically generated in the product data management system after the design is finished.

And secondly, supplementing the main data related attributes applied in the main data system by designers after supplementing auxiliary materials and other figures in the three-dimensional model tree, initiating a design file approval process, carrying out design manufacturability review by the relevant personnel such as technologists, and forming a product EBOM (namely, a design BOM) after approval after completing process countersigning.

And thirdly, returning the design files with unqualified work inspection to perfect design modification, and after the work inspection is qualified, a process worker can start to compile the PBOM and determine information such as a process route, materials and the like of the product part assembly, wherein the information specifically comprises the following steps: the method comprises the steps of self-making outsourcing, whether the outsourcing is made internally or not, a main pipe unit, a main manufacturing unit, a blank type, a blank/outsourcing manufacturer, a blanking size, the number of the producible products, a single-piece process quota and the like. After the product design approval process is completed, a process route and a material rating approval process can be initiated. After the PBOM is controlled, materials and PBOM structures are synchronized to an enterprise resource management system and a manufacturing execution system.

Fourthly, after the process route and the material rating approval are finished, process personnel plan a manufacturing process route, allocate resources, set inspection points, and compile available processes of a downstream manufacturing execution system according to a structured process compilation method according to the principle of one step, one diagram, one card and one inspection, and specifically comprises the following steps: the process structure tree is formed by process routes, operation steps, process drawings, detection parameters, check points, distribution of loading parts, distribution of process resources and the like, and is issued to a manufacturing execution system along with the structured process.

And fifthly, binding the received product data management system issued process with the production order issued by the enterprise resource management system in the manufacturing execution system by the user, and starting product production. After production is finished, according to actual installation actions, information of actual production and processing of the product is summarized to form a product implementation BOM.

Furthermore, the technical state in the product data management system is traced forward. In the forward tracing process, the following implementation modes can be included:

first, based on phase state tracing.

The version management of the design file is carried out, and the stage marking, the change of the design data, the stage conversion of the design data and the like can be traced through the version of the design file and the version of the stage marking.

Second, process tracing.

For the processes related to different versions of the product at the same stage, the process files corresponding to the current version can be checked by selecting the design files of different versions.

For the process tracing of different product stages, the corresponding process file of the current stage can be checked by selecting the product of the specified stage.

And thirdly, inquiring the manufactured information of the enterprise resource management system.

The method is integrated with an enterprise resource management system, and by transmitting main data coding information to the enterprise resource management system, the method inquires the in-transit (outsourcing and outsourcing) and manufactured (inventory) state information display of the materials returned by the enterprise resource management system.

Fourth, the manufacturing execution system is queried for work-in-process information.

And the material manufacturing state information display is acquired through the information of 'pattern code' and the like by integrating with a manufacturing execution system.

Furthermore, the product quality is reversely traced.

The product quality reverse tracing takes a production plan order as a main route, and quality information of the product in the whole process of receiving a production plan from the production plan and finishing the production plan is displayed in a manufacturing execution system by taking a product certificate number or a tracking card digital label as a key path. As an illustration example of product quality tracking, fig. 4 is a schematic diagram of a specific product quality tracking process proposed in an embodiment of the present application, and product quality tracking may be performed in the manner shown in fig. 4.

In addition, the manufacturing execution system can trace the quality data and the maintenance record of the product in the production process through the stored production related data. The user may select the engine number for output of the quality report. The reverse retrospective management of the product matching table is established on the basis of batch management of raw materials and finished products, and the retrospective relation between the finished products and the raw materials is established through batch numbers. By means of pedigree tracing management, a part file for each engine can be established, and after a problem is found, a batch of related materials or a unique identification of used parts can be conveniently found.

Specifically, the product pedigree tracing may include the following ways:

the first way, the engine traces the part:

product number- > order number- > product file- > part lot number- > supplier number

The second way, the part traces back the engine:

supplier number- > part batch number- > product file- > order number- > product number

The product tracking problem is the combination of the two modes, and the specific flow is as follows:

find specific product problem- > engine tracing part- > supplier number- > supplier survey- > supplier number- > part tracing engine- > problem product number.
