Description

Technical Field

[0001] The present application relates to the technical field of vehicle trial production information management, and in particular to a trial production process change management method, device, equipment and readable storage medium. Background Art

[0002] During the trial production of the whole vehicle, the sources of trial production tasks are diverse, the types of parts are many, the trial production workload is large, and the time requirements are urgent. In addition, the R&D nature of trial production makes it more personalized than mass production. Due to changes in R&D projects, the trial production BOM (Bill of Materials) and trial production plans change frequently, the types and quantities of parts change frequently, and the properties of trial production parts (specificity, versatility, procurement and suppliers) are diverse and changeable. The differences caused by the changes need to be dealt with in a timely manner at all stages of the entire trial production business.

[0003] However, the current management system is mainly used for the procurement of parts and production management scenarios for mass production of complete vehicles. Its management process is relatively unified, the changes in vehicle procurement needs are relatively small, the changes in vehicle manufacturing BOM and planning levels are relatively small, procurement is relatively centralized, and the procurement process is simpler than the business of trial production, making it difficult to meet the needs of multiple changes in trial production scenarios.

[0004] In summary, due to the large number of changes and frequent changes involved in each stage of trial production, the current management system is not efficient enough in managing changes in each stage of trial production. Summary of the invention

[0048] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0049] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0050] In a first aspect, an embodiment of the present application provides a trial production process change management method.

[0051] In one embodiment, referring to Figure 1 , Figure 1 This is a flow chart of an embodiment of the trial production process change management method of the present application, as shown in Figure 1 As shown in the figure, the trial production process change management method includes:

[0052] Step S10: When a material change occurs in the upstream link of the trial production process, a material change notification is sent to the downstream links step by step.

[0053] In this embodiment, the five common links of the trial production process, namely the bill of materials, trial production plan, material requirements, procurement tasks and warehousing, are taken as examples. The bill of materials and trial production plan links are the upstream links of the trial production process, and the material requirements, procurement tasks and warehousing links are the downstream links of the trial production process. The three downstream links are in an upstream and downstream relationship in order. When material changes occur in the bill of materials and trial production plan links upstream of the trial production process, such as the addition or deletion of material categories, the increase or decrease of material quantities, and the changes in key or non-key attributes of materials, the material changes in the upstream links will have corresponding impacts on the downstream material requirements, procurement tasks and warehousing links, and these impacts are generated step by step according to the relationship between the upstream and downstream. Therefore, it is necessary to send material change notifications to the downstream links step by step, so that the downstream links can perform corresponding changes after receiving the material change notifications, thereby achieving synchronization and unification of material changes in each link of the trial production process.

[0054] Step S20, for each downstream link, after receiving the material change notification sent by the previous link, the current link detects whether the change content requires feedback from the next link.

[0055] In this embodiment, for each link of downstream material demand, procurement tasks and warehousing, it can be pre-configured which material change item types require feedback from downstream links and which material change item types do not require feedback from downstream links. After the current link receives the material change notification sent by the previous link, it queries the pre-configuration according to the material change item type to detect whether the change content requires feedback from the next link. Taking the material demand link as the current link as an example, the previous upstream link is the material list or trial production plan link, and the next downstream link is the procurement task link.

[0056] Step S30: If no feedback is required from the next link, the current link executes the material change after receiving the confirmation change instruction and sends a material change notification to the next link.

[0057] In this embodiment, if the query detects that the current material change item type does not require feedback from the next link, the current link of the trial production process management system can directly execute the material change after receiving the confirmation change instruction entered by the user, and then continue to send the material change notification to the next link.

[0058] Step S40: If feedback from the next link is required, a material change notification is sent to the next link, and feedback from the next link is awaited.

[0059] In this embodiment, if it is detected through query that the current material change item type requires feedback from the next link, the current link of the trial production process management system cannot directly execute the material change. It is necessary to first send a material change notification to the next link and wait to receive feedback from the next link. The decision on whether the change can be executed is made based on the feedback from the next link.

[0060] Step S50, if the feedback from the next link is that the change is completed, the current link will execute the material change after receiving the confirmation change instruction, and feedback the change completion to the previous link.

[0061] In this embodiment, if the feedback from the next link is that the change is completed, the current link of the trial production process management system will execute the material change after receiving the confirmation change instruction entered by the user. This ensures that after the change in the downstream link is completed, the current link can also execute the change to keep the material updated synchronously, and feedback the change completion to the previous link so that the upstream link can also execute the change to keep the material updated synchronously.

[0062] Step S60: If the feedback of the next link is that it cannot be changed, a manual intervention prompt is output and feedback that it cannot be changed is given to the previous link.

[0063] In this embodiment, since the trial production process management system cannot automatically complete the synchronous change of certain material changes through programmed processing, if the feedback from the next link is that the change cannot be made, a manual intervention prompt is output and feedback is given to the previous link that the change cannot be made, requesting manual intervention to handle the abnormal data, so as to maintain the consistency of material change data in each link of the trial production process management system through manual intervention processing.

[0064] In this embodiment, when material changes occur in the upstream bill of materials and trial production plan links of the trial production process, such as the addition or deletion of material categories, the increase or decrease of material quantities, and the changes in key or non-key material attributes, material change notifications are sent to the downstream material requirements, procurement tasks, and warehousing links step by step, where the three downstream links have upstream and downstream relationships with each other in sequence, and the downstream links perform corresponding processing according to different situations step by step. Specifically, each downstream link executes material changes or requests manual intervention to process material changes according to whether feedback from the next link is needed and the feedback content of the next link, and continues to feedback to the upper link, so that each link of the trial production process can accurately and efficiently keep in sync with the material changes that occur, and can promptly request manual intervention for abnormal situations that cannot be changed as fed back by the next link, so that it can flexibly adapt to various types of high-frequency material changes in the trial production scenario, and make the processing of changes in each link of the trial production process form a closed loop and remain unified, which can better meet the needs of trial production process management. It should be noted that this embodiment only takes the five common links of the trial production process, namely the bill of materials, trial production plan, material requirements, procurement tasks and warehousing, as examples. More upstream and downstream links of the trial production process can adopt the same or similar processing methods, which will not be repeated here.

[0065] Further, in one embodiment, referring to Figure 2 , Figure 2 For this application Figure 1 The detailed flow chart of step S10 is as follows: Figure 2 As shown, step S10 includes:

[0066] Step S101, when the material category or quantity of materials increases or the non-critical attributes of materials change in the upstream bill of materials and trial production plan of the trial production process, a material change notification is sent to the downstream material demand, procurement tasks and warehousing links step by step;

[0067] Step S102: When the material category is deleted or the material quantity is reduced or the key attribute of the material is changed in the upstream material list and trial production plan of the trial production process, and the change content has not been confirmed by the downstream procurement task link, the material change content is marked and the material change notification is sent to the downstream material demand, procurement task and warehousing links step by step;

[0068] Step S103, when the material category is deleted or the material quantity is reduced or the key attribute of the material is changed in the upstream material list and trial production plan of the trial production process, and the change content has been confirmed by the downstream procurement task link, the material change content is marked, and the material change notification is sent to the downstream material demand, procurement task and warehousing links step by step for difference processing.

[0069] In this embodiment, the bill of materials and trial production plan are the upstream links of the trial production process. The bill of materials is the source of trial production materials for complete vehicles and complete machines. Changes in the bill of materials mainly include additions and deletions of parts categories, increases and decreases in the usage of single-vehicle parts, and adjustments to key attributes of parts (notification number, whether integrated procurement and solution conception). The trial production plan is mainly divided into annual plans and monthly plans, which correspond to plans at the complete vehicle and complete machine level and plans at the component material level, respectively. Changes in the trial production plan mainly include increases and decreases in the planned quantity of complete vehicles and complete machines, changes in configuration levels, increases and decreases in the planned quantity of component trial production, and additions and deletions of categories. In summary, the types of material changes involved in the bill of materials and trial production plan links can be mainly divided into additions or deletions of material categories, increases or decreases in material quantities, and changes in key or non-key attributes of materials. Different processing methods and change notification methods can be adopted for different types of changes. Specifically, if there is an increase in material categories or an increase in material quantities or a change in non-key attributes of materials in the upstream bill of materials and trial production plan links, such changes are relatively simple and the trial production After notifying and obtaining user confirmation, the process management system can complete the synchronous processing of the change by itself. It only needs to send material change notifications to the downstream material requirements, procurement tasks and warehousing links step by step. For the deletion of material categories or reduction of material quantities or changes in key material attributes in the upstream material list and trial production plan links, and the changes have not been confirmed by the downstream procurement task link, since the changes have not been confirmed by the downstream procurement task link, it is only necessary to mark the material changes and send material change notifications to the downstream material requirements, procurement tasks and warehousing links step by step. For the deletion of material categories or reduction of material quantities or changes in key material attributes in the upstream material list and trial production plan links, and the changes have been confirmed by the downstream procurement task link, since the changes have been confirmed by the downstream procurement task link, the downstream links must perform difference processing, so the material changes are marked, and material change notifications for difference processing are sent to the downstream material requirements, procurement tasks and warehousing links step by step.

[0070] Furthermore, in one embodiment, when a key material attribute changes in the upstream bill of materials and trial production plan of the trial production process, the trial production process change management method further includes:

[0071] When the upstream bill of materials and trial production plan link receives feedback from the downstream link that cannot be changed, new material categories are added for the materials with key attribute changes so that the downstream can initiate new procurement tasks.

[0072] In this embodiment, a change in a key attribute of a material is equivalent to the creation of a new material category. When the upstream bill of materials and trial production plan link receives feedback from the downstream link that it cannot be changed, in order to meet the change requirements of the trial production process, it is necessary to add a new material category for the material with the key attribute change so that the downstream link can initiate a new procurement task.

[0073] Furthermore, in one embodiment, the trial production process change management method further includes:

[0074] The downstream material demand link calculates the change quantity of material demand based on the material changes in the upstream material list and trial production plan link.

[0075] In this embodiment, the change of the material requirement module belongs to the core and key link of the trial production process change. It accepts the change difference input from the bill of materials and trial production plan link. It is the source of the change of procurement tasks and warehousing links. The material requirement change difference processing determines whether the trial production multi-scenario change can be achieved as required. It is easy to understand that the functional module of material requirement is mainly composed of the material requirement bottom table, summary table, gap calculation, etc., among which the bottom table is the basic table for material requirement calculation. All bills of materials, vehicle and machine trial production plans, and parts material trial production plans will refer to the materials and their single vehicle coefficients for calculation and store them in the bottom table. Then the material requirement module will merge the material requirements according to the attributes such as material code, supplier, manufacturing assembly route and arrival point. The merged data is stored in the material requirement summary table as the input of the subsequent procurement task link. When the material changes in the upstream bill of materials and trial production plan link, the material requirement link calculates the change quantity of the material requirement according to the content of the material change. The change quantity of the material requirement mainly includes increase and decrease.

[0076] Further, in one embodiment, referring to Figure 3 , Figure 3 This is a schematic diagram of the change execution process of an embodiment of the application trial production process change management method, such as Figure 3 As shown, the execution of material change includes:

[0077] Step S01, when the change quantity is changed to increase, if the purchase task link has not generated a purchase task, the material demand link will increase the material demand; if the purchase task link has generated a purchase task, the purchase task link will add a purchase task for the increased material;

[0078] Step S02, when the change quantity is changed to decrease, if the purchase task link has not generated a purchase task, the material demand link will reduce the material demand; if the purchase task link has generated a purchase task, the material demand link will reduce the material demand after the purchase task is rolled back;

[0079] Step S03, when the material change content is a change in the key attributes of the material, if the procurement task link has not generated a procurement task, the material requirement link will increase the material requirement; if the procurement task link has generated a procurement task, the material requirement link will increase the material requirement after the procurement task is rolled back.

[0080] In this embodiment, in the case where the changed quantity calculated in the material demand link is changed to an increase, if the procurement task link has not yet generated a procurement task, the material demand link can simply increase the material demand, and the procurement link can generate a procurement task for the increased material demand. If the procurement task link has already generated a procurement task, the procurement task link will add a procurement task for the added material. In the case where the changed quantity calculated in the material demand link is changed to a decrease, if the procurement task link has not yet generated a procurement task, the material demand link can simply reduce the material demand. The procurement link can generate a procurement task for the reduced material demand. If the procurement task link If the procurement task has been generated in the procurement task link, the material demand link needs to reduce the material demand after the procurement task is rolled back. There is also a situation where the material change content is the change of the material's key attributes. As mentioned above, the change of the material's key attributes is equivalent to the addition of a new material category. Therefore, if the procurement task link has not yet generated a procurement task, the material demand link can simply increase the material demand, that is, increase the material demand for the material with the key attribute change. The procurement link can generate procurement tasks for the increased material demand. If the procurement task link has already generated a procurement task, the material demand link needs to increase the material demand after the procurement task is rolled back. It should be noted that R&D and trial production procurement business involves many business scenarios, and its changes need to meet different procurement business scenarios. The change difference input of the procurement task link mainly comes from the upstream material demand link, involving the increase or decrease of the number of parts, the increase or decrease of parts categories, the unit price of parts, the total price of parts, tooling costs, other costs, etc., and the input of changes in other material demand fields. The corresponding changes in the procurement task link include changes in important procurement information, changes in non-important procurement information, and changes in business contracts. The trial production process management system determines the category of procurement changes based on the specific change inputs and reminds business personnel to execute the procurement changes.

[0081] Furthermore, in one embodiment, the executing material change further includes:

[0082] When the quantity change is reduced, if there is no similar replaceable inventory part in the inventory, the warehouse inventory link will perform the return process; if there is a similar replaceable inventory part in the inventory, the warehouse inventory link will deduct the inventory of the similar replaceable inventory part;

[0083] When the quantity is changed to increase, the warehouse inventory link performs warehousing processing for the increased materials.

[0084] In this embodiment, for the warehousing inventory link, if the material change quantity is changed to a decrease when the material change notification is received, if there are no similar replaceable inventory parts in the inventory for deduction, the warehousing inventory link must execute the return processing; if there are similar replaceable inventory parts in the inventory, the warehousing inventory link can perform inventory deductions for the similar replaceable inventory parts; if the material change quantity is changed to an increase when the material change notification is received, the warehousing inventory link executes the warehousing processing for the increased materials.

[0085] Furthermore, in one embodiment, the executing material change further includes:

[0086] When the quantity change is an increase or decrease, if no material picking occurs, the warehouse picking link updates the picking list and the collection list according to the changed quantity of material demand;

[0087] When the quantity change is changed to increase, if material picking has already occurred, the warehouse picking link will add a new picking list and collection list for the added materials;

[0088] When the quantity is changed to decrease, if material picking has already occurred, the warehouse picking link will update the picking list and the collection and distribution list after the return processing. The collection and distribution list is generated after aggregation based on the picking list, and the picking list is generated based on the bill of materials and the trial production plan.

[0089] In this embodiment, for the warehouse picking link, if the material change quantity is changed to increase or decrease when the material change notification is received, if the picking has not yet occurred, the warehouse picking link can update the picking list and the collection and distribution list according to the changed quantity of material demand. If the changed quantity is changed to increase and the picking has already occurred, the warehouse picking link will add a picking list and a collection and distribution list for the increased materials. If the changed quantity is changed to decrease and the picking has already occurred, the warehouse picking link needs to update the picking list and the collection and distribution list after the return processing, where the collection and distribution list is generated after aggregation based on the picking list, and the picking list is generated based on the material demand. The bill of materials and trial production plan are generated. A single material requisition is generated according to the trial production task order, vehicle model, assembly route, arrival date attributes corresponding to the standard parts of material requirements and the number of vehicles to be loaded in the trial production plan (specific to a single vehicle). The loading material requisition calculated according to the above process is the material requisition list data corresponding to a certain trial production task, a certain vehicle model, a certain assembly scene (final assembly, welding, etc.), a certain arrival time and a specific vehicle, and excludes the data that has been picked before. The collection order is summarized according to the material requisition list of each task of the assembly line on the same day or at a specific time.

[0090] In a second aspect, an embodiment of the present application also provides a trial production process change management device.

[0091] In one embodiment, referring to Figure 4 , Figure 4 This is a functional module diagram of an embodiment of a trial production process change management device for this application, such as Figure 4 As shown, the trial production process change management device includes:

[0092] The first notification module 10 is used to send material change notifications to downstream links step by step when a material change occurs in the upstream link of the trial production process;

[0093] The detection module 20 is used for each downstream link to detect whether the change content requires feedback from the next link after receiving the material change notification sent by the previous link;

[0094] The first change module 30 is used for executing the material change after receiving the confirmation change instruction if there is no need for feedback from the next link, and sending a material change notification to the next link;

[0095] The second notification module 40 is used to send a material change notification to the next link if feedback from the next link is needed, and wait to receive feedback from the next link;

[0096] The second change module 50 is used for executing the material change after receiving the confirmation change instruction if the feedback of the next link is that the change is completed, and feeding back the change completion to the previous link;

[0097] The output module 60 is used to output a manual intervention prompt and feedback to the previous link that it cannot be changed if the feedback of the next link is that it cannot be changed.

[0098] Furthermore, in one embodiment, the first notification module 10 is used to:

[0099] When the material category or quantity of materials increases or the non-critical attributes of materials change in the upstream bill of materials and trial production plan of the trial production process, material change notifications are sent to the downstream material requirements, procurement tasks and warehousing links step by step;
