Description

Technical Field

[0001] The present invention relates to the field of product data management, and particularly to a method, device, equipment and readable storage medium for managing design changes of common parts for vehicle models. Background Art

[0002] With the booming development of the automotive industry, new car manufacturers have emerged like mushrooms after a spring rain, and the competition in the automotive market has become increasingly fierce. As a result, the R & D cycle of automobiles has been continuously compressed, and agile development has become an inevitable trend. The compression of the development cycle, the contraction of costs, the improvement of quality requirements, and the frequent changes in market demands have all directly led to frequent changes in the project boundaries of new vehicle model development and post-production, and thus a substantial increase in the number of design changes. Referring to the design changes of a typical new vehicle model in China from the engineering design stage to 6 months after its launch, the number is as high as nearly 3,000 times.

[0003] Ideally, the implementation and introduction of design changes are carried out in an orderly manner. However, in reality, there is a situation where one (or more) parts are used by multiple vehicle models at the same time. Referring to a typical new vehicle model in China with forward development, the number of common parts is as high as 1,500.

[0004] The design changes of common parts will affect all vehicle models using this part. At this time, the complexity and impact scope of the implementation and introduction of design changes increase. After the design changes of common parts for multiple vehicle models occur, due to mutual influence, if there is no effective control method for the implementation and introduction of design changes of common parts, and then according to the implementation and introduction method of design changes for a single vehicle model, due to issues such as non-intercommunication of implementation and introduction information among vehicle models and inconsistent implementation and introduction progress, the management of the implementation of design changes for special parts of multiple vehicle models will be chaotic and out of control, such as:

[0005] 1) It is impossible to locate the first vehicle model using the part. After the part is sent to the manufacturing system, the change management personnel cannot determine which vehicle model's change management personnel will manage this part;

[0006] 2) The change management personnel of each vehicle model cannot accurately receive the change notice, and there may even be omissions;

[0007] 3) The implementation and introduction progress within each vehicle model is not unified. The information sources received by downstream procurement, quality, process, and production switchover personnel are not unified, and the switchover instructions received by suppliers are not unified, resulting in the loss of control over the implementation and introduction of design changes, and ultimately leading to the delay of project plans for multiple vehicle models or the suspension of production lines of the vehicle manufacturer.

[0060] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0061] In a first aspect, an embodiment of the present invention provides a vehicle model common part design change management device.

[0062] Referring to Figure 1 , Figure 1 It is a schematic diagram of the hardware structure of the vehicle model common part design change management device involved in the embodiment solution of the present invention. In the embodiment of the present invention, the vehicle model common part design change management device may include a processor 1001 (such as a Central Processing Unit, CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Among them, the communication bus 1002 is used to realize the connection and communication between these components; the user interface 1003 may include a display screen (Display) and an input unit such as a keyboard (Keyboard); the network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a Wireless-FIdelity, WI-FI interface); the memory 1005 may be a high-speed random access memory (random access memory, RAM), or a stable memory (non-volatile memory), such as a disk memory, and the memory 1005 may optionally also be a storage device independent of the aforementioned processor 1001. Those skilled in the art can understand, Figure 1The hardware structure shown does not constitute a limitation on the present invention, and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0063] Continuing to refer to Figure 1 , Figure 1 In the memory 1005, which is a computer storage medium, an operating system, a network communication module, a user interface module, and a vehicle model common part design change management program may be included. Among them, the processor 1001 may call the vehicle model common part design change management program stored in the memory 1005 and execute the vehicle model common part design change management method provided by the embodiments of the present invention.

[0064] In a second aspect, embodiments of the present invention provide a vehicle model common part design change management method.

[0065] Referring to Figure 2 , Figure 2 is a schematic flowchart of an embodiment of the vehicle model common part design change management method of the present invention.

[0066] In an embodiment of the vehicle model common part design change management method of the present invention, the vehicle model common part design change management method includes:

[0067] Step S10, when receiving a design change initiation instruction for a target part, determine the relevant vehicle model codes corresponding to the target part;

[0068] In this embodiment, there are some target parts in the vehicle BOM of each vehicle model, and these target parts are common parts shared with other relevant vehicle models. When design changes occur to such target parts, the vehicle models using these target parts will affect each other. Therefore, when receiving a design change initiation instruction for a target part, it is necessary to first determine the relevant vehicle model codes corresponding to the target part.

[0069] Further, in an embodiment, before the step S10, it includes:

[0070] Step S01, record the release time of the target part and the time when each vehicle model first uses the target part, where the target part is a multi-vehicle model common part;

[0071] Step S02, based on the release time of the target part and the time when each vehicle model first uses the target part, label the first vehicle model code that first calls the target part to the first field corresponding to the target part, and label the vehicle model codes of each vehicle model that calls the target part to the second field corresponding to the target part;

[0072] Step S03, based on the part code of the target part, the first field, and the second field, construct a relevant vehicle model set model of the target part.

[0073] In this embodiment, considering that in the existing solution, the relevant vehicle models corresponding to the target part are determined based on the content in the design change notice, and the design change notice is filled in manually, which may cause omissions. Therefore, in the solution of this embodiment, two attribute management fields are added to each target part in the management system: the first field and the second field. When generating the vehicle BOM corresponding to each vehicle model, the above-mentioned first field and second field will be marked. Specifically, record the release time of the target part (a common part for multiple vehicle models) in the manufacturing system and the time when each vehicle model first uses the above-mentioned target part. Based on the recorded release time of the target part and the time when each vehicle model first uses the above-mentioned target part, the first vehicle model code that first calls the target part and all the vehicle model codes that call the target part can be determined. Mark the first vehicle model code that first calls the target part to the first field, and mark the vehicle model codes of each vehicle model that calls the target part to the second field corresponding to the target part. The content of the above-mentioned first field and second field will change in real time based on the change of the vehicle models using the target part. Based on the part code of the target part, the first field and the second field, a relevant vehicle model set model of the target part can be constructed. The above-mentioned relevant vehicle model set model will also change in real time with the change of the vehicle models using the target part. The above method can prevent the omission of the relevant vehicle models using the target part, thus ensuring the accuracy and timeliness of the record of the vehicle models using the target part, and ensuring that the control persons in charge of all affected vehicle models can receive the design changes accurately and in a timely manner.

[0074] Furthermore, in one embodiment, referring to Figure 3 , the step S10 includes:

[0075] When receiving the design change initiation instruction for the target part, determine the relevant vehicle model codes corresponding to the target part based on the relevant vehicle model set model corresponding to the target part.

[0076] In this embodiment, before the design change of the target part is initiated, a relevant vehicle model set model corresponding to the target part has been constructed based on the part code of the target part, the first field and the second field. The above-mentioned relevant vehicle model set model includes all the vehicle model codes using the above-mentioned target part and the first vehicle model code that first uses the above-mentioned target part. Therefore, after the relevant vehicle model set model of each target part is constructed, when receiving the design change initiation instruction for the target part by the designer in the design system, that is, applying the relevant vehicle model set model corresponding to the target part, the relevant vehicle model codes corresponding to the target part can be calculated. Among them, the accuracy of the relevant vehicle model codes obtained by the above method is high.

[0077] Step S20, obtain the design change implementation node of the relevant vehicle model codes corresponding to the target part, and based on the design change implementation node, determine the main control person and the deputy control person corresponding to the target part;

[0078] In this embodiment, after obtaining the relevant vehicle model codes corresponding to the target part, the designer will define the design change implementation nodes of each relevant vehicle model in the design system based on the obtained relevant vehicle model codes corresponding to the target part. The above-mentioned design change implementation nodes of each relevant vehicle model are the time nodes for implementing design changes of the target part on each used vehicle model. Based on the above time nodes, the main controller and the deputy controller corresponding to the target part can be determined. Therefore, when receiving the design change initiation instruction of the target part, after determining the relevant vehicle model code corresponding to the target part, it is necessary to obtain the design change implementation node of the relevant vehicle model code corresponding to the target part, and based on the design change implementation node, determine the main controller and the deputy controller corresponding to the target part, so as to distinguish the main and deputy controllers of the design change and automatically complete the distribution of the control tasks. Among them, the main controller and the deputy controller have different control authorities, and the authority level of the main controller is higher than that of the deputy controller, which can avoid the problem that when multiple vehicle models simultaneously perform design changes on the target part, the authority levels of the design change control responsible persons of each vehicle model are the same, and it is impossible to coordinate and confirm all relevant information of all relevant vehicle models.

[0079] Further, in one embodiment, the step of determining the main controller and the deputy controller corresponding to the target part based on the design change implementation node includes:

[0080] If the times corresponding to the design change implementation nodes of each vehicle model are different, the design change responsible person corresponding to the vehicle model code with the earliest corresponding time in the implementation nodes is used as the main controller, and the design change responsible persons corresponding to other relevant vehicle model codes are used as the deputy controllers;

[0081] If the times corresponding to the design change implementation nodes of each vehicle model are the same, the design change responsible person corresponding to the first launched vehicle model code is used as the main controller, and the design change responsible persons corresponding to other relevant vehicle model codes are used as the deputy controllers.

[0082] In this embodiment, specifically, the steps of determining the main controller and the deputy controller corresponding to the target part based on the design change implementation node include: If the times corresponding to the design change implementation nodes of each vehicle model are different, the design change person in charge corresponding to the vehicle model code with the earliest corresponding time in the implementation nodes is used as the main controller, and the design change persons in charge corresponding to other relevant vehicle model codes are used as the deputy controllers. If the times corresponding to the design change implementation nodes of each vehicle model are the same, the design change person in charge corresponding to the first launched vehicle model code is used as the main controller, and the design change persons in charge corresponding to other relevant vehicle model codes are used as the deputy controllers. For example: The design change implementation nodes of relevant vehicle models 1, 2, 3,... are D1, D2, D3..., respectively, where D1 is the first launched vehicle model. When D1 > D2\D3..., it is determined that the design change control person in charge of vehicle model 1 is used as the main controller, and the design change control persons in charge of vehicle models 2, 3,... are used as the deputy controllers; D2 > D1\D3,... It is determined that the design change control person in charge of vehicle model 2 is used as the main controller, and the design change control persons in charge of vehicle models 1, 3,... are used as the deputy controllers; D3 > D1\D2,... It is determined that the design change control person in charge of vehicle model 3 is used as the main controller, and the design change control persons in charge of vehicle models 1, 2,... are used as the deputy controllers; D1 = D2 = D3,... It is determined that the design change control person in charge of the first launched vehicle model 1 is used as the main controller, and the design change control persons in charge of vehicle models 2, 3,... are used as the deputy controllers.

[0083] Through the above method, that is, when the implementation nodes are the same, the control person in charge corresponding to the first launched vehicle model is used as the main controller; when the implementation nodes are different, the control person in charge of the vehicle model with the earliest design change implementation node is used as the main controller. It can avoid the problem of management chaos caused by the inability to determine the main controller for overall management when multiple vehicle models simultaneously carry out design changes on the target part.

[0084] Step S30: Send the design change implementation node and the design change notice to the main controller and the deputy controller;

[0085] In this embodiment, before obtaining the design change implementation node of the relevant vehicle model code corresponding to the target part and determining the main controller and the deputy controller corresponding to the target part based on the above design change implementation node, a corresponding system account has already been established in the manufacturing system for the vehicle model control person corresponding to the relevant vehicle model code of the target part. After determining the design change implementation node, the corresponding main controller and the deputy controller of the relevant vehicle model code of the target part, the design change implementation node and the design change notice can be sent to the main controller and the deputy controller. When sending the design change notice, the main controller and the deputy controller can be notified by means such as the system account email of the manufacturing system, and different task chains are established for the system accounts of the main controller and the deputy controller. Different task chains correspond to different control authorities. The deputy controller only has the authority to reply and confirm the design change notice, and the main controller also has the authority to summarize and confirm the reply situations of the deputy controller and other relevant personnel.

[0086] Step S40: Obtain the production preparation tasks created by the main controller based on the design change implementation node and the design change notice, and send the production preparation tasks to the target personnel, where the target personnel include the deputy controller, the purchasing personnel, the quality personnel, the process personnel, and the production switchover personnel.

[0087] In this embodiment, after the main controller receives the sent design change implementation node and the design change notice, production preparation tasks will be created based on the above design change implementation node and the design change notice. The above production preparation tasks need to be sent to the target personnel in a coordinated manner for information confirmation. Therefore, after sending the design change implementation node and the design change notice to the main controller and the deputy controller, it is necessary to obtain the above production preparation tasks, send the production preparation tasks to the target personnel, and conduct summary collection and confirmation of information such as the production preparation cycle, the inventory quantity, the sample delivery cycle and quantity, and the estimated switchover time. The target personnel include the deputy controller, the purchasing personnel, the quality personnel, the process personnel, and the production switchover personnel.

[0088] Step S50: Obtain the confirmation information of the target personnel for the production preparation tasks, and based on the confirmation information, change the trial assembly verification control information, the inventory quantity control information, and the switchover time control information of the target part.

[0089] In this embodiment, after the target personnel receive the production preparation task, they will feedback the confirmation information for the production preparation task. Based on the confirmation information feedback by the above-mentioned target personnel, the trial assembly verification control information, inventory quantity control information, and switching time control information of the target part can be changed. Therefore, after the production preparation task is issued to the target personnel, the confirmation information of the target personnel for the production preparation task can be obtained, and based on the confirmation information, the trial assembly verification control information, inventory quantity control information, and switching time control information of the target part can be changed. The above-mentioned trial assembly verification control information of the target part, such as determining whether the target part is qualified for trial assembly verification on all relevant vehicle models; the above-mentioned inventory quantity control information of the target part, such as determining whether the quantity of old parts (target parts before design change) in the inventory supports the normal production of relevant vehicle models before the change according to the implementation node of the design change, calculating and alarming for abnormal inventory situations; the above-mentioned switching time control information of the target part, such as determining the production switching time for relevant vehicle models to change from old parts (target parts before design change) to new parts (target parts after design change) based on the trial assembly results and implementation nodes. Through the task chain of the main controller, the design change of multi-vehicle common parts can be overall controlled, which can effectively ensure the intercommunication of control information of each vehicle model and the unity of control progress, and by unifying the information sources of downstream procurement, quality, and process acceptance and the production switching instructions received by suppliers, the orderly and precise management of the design change of multi-vehicle common parts is guaranteed, and the stable production of the manufacturing plant is ensured.

[0090] Further, in one embodiment, referring to Figure 4 , the steps of obtaining the confirmation information of the target personnel for the production preparation task include:

[0091] Step S60, obtaining the sample part requirement quantity of the target part after the change of the corresponding vehicle model confirmed by the deputy controller, and the tracking result of the trial assembly verification corresponding to the target part after the change;

[0092] Step S70, obtaining the inventory quantity of the target part before the change confirmed by the purchasing personnel, and the production preparation cycle and quantity of the external parts corresponding to the target part after the change;

[0093] Step S80, obtaining the quality confirmation result of the trial assembly sample parts corresponding to the target part after the change confirmed by the quality personnel;

[0094] Step S90, obtaining the influence information of the target part after the change on the process assembly, and the production preparation cycle and quantity of the internal parts corresponding to the target part after the change confirmed by the process personnel;

[0095] Step S100, obtaining the switching time corresponding to the target part after the change confirmed by the production switching personnel.

[0096] In this embodiment, specifically, the steps of obtaining the confirmation information of the production preparation tasks by the target personnel include: obtaining the sample requirement quantity of the target parts after the corresponding vehicle model change confirmed by the deputy controller, and the tracking results of the trial assembly verification for the target parts after the change. Obtaining the inventory quantity of the target parts before the change confirmed by the purchaser, as well as the production preparation cycle and quantity of the external parts corresponding to the target parts after the change. Obtaining the quality confirmation results of the trial assembly samples corresponding to the target parts after the change confirmed by the quality personnel. Obtaining the information on the impact of the target parts after the change on the process assembly, as well as the production preparation cycle and quantity of the in-house parts corresponding to the target parts after the change. Obtaining the switching time corresponding to the target parts after the change confirmed by the production switchover personnel. The confirmation information obtained above can ensure the information interconnection, progress unification of the implementation of each vehicle model, and the information unification of downstream procurement, quality, and process.

[0097] In this embodiment, considering the problem that after the design change of the common parts shared by multiple vehicle models in the existing solution, due to the mutual influence of multiple vehicle models, if the single vehicle model design change implementation management method is followed, the implementation management will be chaotic and out of control. For example: for vehicle model 1, design changes occur to parts A, B..., the common part A is changed to part C, and part B is changed to D, and C and D must be switched synchronously. The design change controller A of vehicle model 1 conducts design change control, issues the design change notice to the corresponding procurement, quality, process, and production switchover personnel of vehicle model 1, and conducts production switchover for vehicle model 1 according to the control information and progress. For vehicle models 2...N, design changes occur to parts A, E..., the common part A is changed to part C, and part E is changed to F, and C and F must be switched synchronously. The design change controller B of vehicle model 2 conducts design change control, issues the design change notice to the corresponding procurement, quality, process, and production switchover personnel of vehicle models 2...N, and conducts production switchover for vehicle models 2...N according to the control information and progress. In the above situations, the information of the design change controllers of vehicle models 1, 2...N is not interconnected, and the information of the corresponding procurement, quality, process, and production switchover personnel is not interconnected. If the control progress of vehicle model 1 is faster than that of vehicle models 2...N, parts C and D have passed the trial assembly verification and the old parts A and B have been consumed and are ready to be switched. But at this time: ① For vehicle models 2...N, due to the omission of relevant vehicle models in the design change notice, they did not receive this design change; ② The trial assembly of parts C and F has not been carried out yet. If the trial assembly of parts C and F for vehicle models 2...N cannot be organized in time, since the common part C has not been verified qualified by trial assembly on all vehicle models, vehicle models 1, 2...N cannot be switched to C, and since part F has not been verified qualified by trial assembly on vehicle models 2...N, vehicle models 2...N cannot be switched to C and F; more seriously, at this time, the old parts A and B have been consumed. If they cannot be immediately switched to C, D, and F, vehicle models 1, 2...N will face the risk of production stoppage and line shutdown.

[0098] Therefore, a method for managing design changes of common parts for vehicle models is provided, which includes: when receiving an instruction to initiate a design change for a target part, determining the relevant vehicle model codes corresponding to the target part; obtaining the design change implementation nodes of the relevant vehicle model codes corresponding to the target part, and based on the design change implementation nodes, determining the main controller and the deputy controller corresponding to the target part; sending the design change implementation nodes and the design change notice to the main controller and the deputy controller; obtaining the production preparation tasks created by the main controller based on the design change implementation nodes and the design change notice, and sending the production preparation tasks to the target personnel, where the target personnel include the deputy controller, purchasing personnel, quality personnel, process personnel, and production switchover personnel; obtaining the confirmation information of the target personnel for the production preparation tasks, and based on the confirmation information, changing the trial assembly verification control information, inventory quantity control information, and switchover time control information of the target part.
