[0136] It should be noted that see Figure 4 , Figure 4 This is a schematic diagram of the pilot master plan generation in the multi-level linkage plan control method of the present invention, such as Figure 4 As shown, when a new trial production master plan is created, the annual plan with a release status and a total number of remaining prototypes / machines greater than 0 is obtained according to the projects and trial production stages in the annual plan, and the test plan details transmitted by the upstream test data management system are traversed to match the test plan data of the same project, the same stage and prototype number and for which a master plan has not been created.

[0137] In the specific implementation, the assembly batch is set, the total number of sample vehicles is divided by the total number of batches, and the number of sample vehicles is evenly divided into all batches, taking into account both single batches and multiple batches. For the case of non-divisibility, the Math.floor function is used to get the maximum integer rounded down, and then all the batches are traversed, and the number that is less than the maximum integer is placed in the last batch. The number of each batch can be freely edited, but it cannot be greater than the total number of sample vehicles.

[0138] It should be understood that the master trial plan for each prototype vehicle is generated in real time based on the reverse order of the prototype vehicle task start time or the forward or reverse order of the loading start time, and the preset algorithm device is called in combination with the professional group trial production cycle library. The master trial production plan is released after confirmation and sent back to the upstream test system to ensure the consistency and linkage of the plans of both parties.

[0139] It can be understood that the test plan includes information such as project number, trial production stage, trial production category, number of prototypes, prototype number, test purpose, and start time of the test task. The annual plan acquisition method includes that each project plan supervisor creates and publishes an annual trial production plan based on the trial production needs, which mainly includes the number of prototypes, delivery date, and batch number. Based on the trial production master plan, a vehicle trial production application is initiated, and a grid plan is automatically generated in combination with the cycle library of the parts and components business department. At the same time, the preset algorithm device is called to match the process cycle library to automatically generate the welding, assembly, and delivery plan. Based on the acquired test plan information and annual plan, the preset algorithm device is called to match the professional group trial production cycle library to automatically generate the initial trial production master plan.

[0140] Step S14: confirm and fine-tune the line-specific planning time of the preliminary version of the trial production master plan to generate a final version of the trial production master plan.

[0141] It can be understood that after confirming and fine-tuning the line-specific planning time of the initial version of the trial production master plan, the final version of the trial production master plan can be generated.

[0142] Through the above scheme, this embodiment obtains the parts business cycle library, professional group trial production cycle library, workshop calendar and process cycle library corresponding to the whole vehicle trial production plan; constructs a model database for automatic scheduling of the whole vehicle trial production plan according to the parts business cycle library, the professional group trial production cycle library, the workshop calendar and the process cycle library; obtains the test plan information and the annual plan from the model database, matches the professional group trial production cycle library according to the test plan information and the annual plan, and automatically generates a preliminary trial production master plan; confirms and fine-tunes the line-specific planning time of the preliminary trial production master plan to generate the final version of the trial production master plan, and can generate the final version of the trial production master plan, ensuring the consistency and linkage of data between plans at different levels, meeting the planning control needs of different roles at different stages, and improving the efficiency of trial production plan preparation and overall control.

[0143] Further, Figure 5 FIG. 1 is a flow chart of a third embodiment of the multi-level linkage planning control method of the present invention. Figure 5 As shown, a third embodiment of the multi-level linkage plan control method of the present invention is proposed based on the first embodiment. In this embodiment, the step S20 specifically includes the following steps:

[0144] Step S21: Initiate a vehicle trial production application according to the trial production master plan, obtain trial production BOM data and business progress information obtained through the upstream procurement system.

[0145] It should be noted that the vehicle trial production application form is initiated based on the trial production master plan, combined with the trial production BOM data and the business progress information obtained from the upstream procurement system.

[0146] Step S22, calling a preset algorithm device to match the trial production BOM data and the business progress information with the parts business cycle library corresponding to the vehicle trial production plan, and generating a grid plan for each part.

[0147] It can be understood that calling the preset algorithm device, matching the parts business cycle library, automatically generating a grid plan for each part, matching the warehouse arrival progress, and updating the parts arrival status in real time makes it easier to grasp the parts business procurement progress, arrival plan, and comparison with the actual execution in real time.

[0148] Furthermore, the step S22 specifically includes the following steps:

[0149] Obtaining part information in the trial production BOM data, and obtaining a parts list and a parts procurement method from the part information;

[0150] Matching the parts list and the parts procurement method with the parts business cycle library corresponding to the vehicle trial production plan to obtain a preliminary grid plan corresponding to the seasonal change plan time;

[0151] Calculate the current stage of the parts and the actual completion time of each business purchase according to the business progress information;

[0152] The warehouse module interface is called to obtain the arrival status of each part, and a grid plan for each component is generated according to the initial grid plan, the actual completion time and the arrival status.

[0153] In the specific implementation, see Figure 6 , Figure 6 This is a schematic diagram of trial-produced grid plan generation in the multi-level linkage plan control method of the present invention, such as Figure 6 As shown in the figure, after the trial production application is released, the parts information under the application form is obtained from the BOM list of the corresponding project in combination with the sample vehicle number and vehicle model configuration of the trial production master plan in the application form, which is used as the data source of the parts list in the parts grid plan; according to the obtained parts list and parts procurement method, the parts business cycle is matched to automatically calculate the planned time of each link to form the initial version of the grid plan; according to the progress of parts procurement of the corresponding documents obtained from the upstream procurement system, the current link of the parts and the actual completion time of each business procurement are automatically calculated, and if the plan is delayed, the risk is actively warned and the person in charge of the trial production is reminded; the warehouse module interface is called to obtain the arrival status of the parts. If it has arrived, the arrival time of the parts is obtained to the actual arrival time in the grid plan.

[0154] Through the above scheme, this embodiment initiates a vehicle trial production application through the trial production master plan, obtains trial production BOM data and business progress information obtained through the upstream procurement system; calls a preset algorithm device to match the trial production BOM data and the business progress information with the parts business cycle library corresponding to the vehicle trial production plan, and generates a grid plan for each part. The grid plan can be generated quickly, ensuring the consistency and linkage of data between plans at different levels, meeting the planning control needs of different roles at different stages, and improving the efficiency of trial production plan preparation and overall control.

[0155] Further, Figure 7 FIG. 4 is a flow chart of a fourth embodiment of the multi-level linkage planning control method of the present invention. Figure 7 As shown, a fourth embodiment of the multi-level linkage plan control method of the present invention is proposed based on the first embodiment. In this embodiment, step S30 specifically includes the following steps:

[0156] Step S31, calling the corresponding preset algorithm according to the trial production application form published in the grid plan, matching the process cycle library according to the preset algorithm, and obtaining the first-level trial production process in the detailed list of the trial production master plan.

[0157] It should be noted that after obtaining the vehicle trial production application form, the trial production resource allocation to-do reminder can be generated in combination with the planned start time of each workshop in the trial production master plan. The assembly supervisor will allocate resources and mainly define and maintain workstations, personnel and production modes.

[0158] In the specific implementation, see Figure 8 , Figure 8 This is a schematic diagram of the automatic scheduling logic of the trial production plan in the multi-level linkage planning control method of the present invention, such as Figure 8 As shown in the figure, based on the released vehicle trial production application form, resource allocation tasks are sent X days in advance according to the planned start time of each workshop in the master plan, and trial production stations, personnel, production modes, etc. are allocated respectively. At the same time, combined with the process cycle library and the workshop work calendar, the planned start time and planned completion time of each line process are calculated, and the trial production plan is automatically generated.

[0159] Step S32, sort the processes in the first-level trial production process, which are equal to welding, final assembly, and delivery, in the order of earliest, and automatically generate a trial production task ledger.

[0160] It can be understood that according to the process cycle model library, the cycle of each process is matched, and at the same time, the first-level trial production process in the trial production master plan details table is sorted according to the earliest plandate_start sequence of "welding assembly", "general assembly" and "shipping assembly", and the trial production task ledger is automatically generated.

[0161] Step S33: Obtain the workshop calendar working days and working hours, and determine the available working time period according to the workshop calendar working days and the working hours.

[0162] It should be understood that the workshop calendar working days and working hours are obtained, and the workable time period can be determined based on the workshop calendar working days and the working hours.

[0163] Step S34, calculating the planned start time and the planned completion time of each line according to the available working time and the production rhythm sequence of the line.

[0164] It can be understood that the planned start time and planned completion time of each line can be calculated based on the working time and the line production rhythm sequence.

[0165] Step S35: After the planned start time and the planned completion time are confirmed and adjusted, a preliminary plan for corresponding welding, final assembly and delivery is generated according to the adjusted planned start time, planned completion time and trial production task ledger.

[0166] It should be understood that after the planned start time and the planned completion time are confirmed and adjusted, a preliminary plan for corresponding welding, final assembly and delivery can be generated based on the adjusted planned start time, planned completion time and the trial production task ledger.

[0167] In the specific implementation, the workable time period is obtained according to the workshop calendar working days and working hours, and the planned start time and planned completion time of each line are calculated according to the working day start time + line production rhythm (unit: hour) sequence (line sequence), and the first version of the trial production plan is produced; the line plan time is confirmed and adjusted to generate the final version of the trial production plan; the generated trial production plan is generated and executed, and the execution results are synchronized to the trial production master plan, so that the trial production plan supervisor can timely grasp the trial production progress and risks.

[0168] Through the above scheme, this embodiment calls the corresponding preset algorithm through the grid plan, matches the process cycle library according to the preset algorithm, obtains the first-level trial production process in the detailed table of the trial production master plan; sorts the processes equal to welding, assembly, and delivery in the first-level trial production process in the earliest order, and automatically generates a trial production task ledger; obtains the workshop calendar working days and working hours, and determines the workable time period according to the workshop calendar working days and working hours; calculates the planned start time and planned completion time of each line according to the workable time and the line production rhythm sequence; after the adjustment is confirmed between the planned start time and the planned completion time, the adjustment is made according to the adjustment The planned start time, the planned completion time and the trial production task ledger are used to generate the initial plan for welding, final assembly and delivery. This ensures the consistency and linkage of data between plans at different levels, meets the planning and control needs of different roles at different stages, and improves the efficiency of trial production plan preparation and overall management and control. Through the pre- and actual comparative analysis of the plan, risk warnings can be sent in a timely and proactive manner, which can effectively reduce the delivery risk of trial production prototypes. Based on the big data model analysis of the actual execution situation, a reasonable cycle can be calculated more accurately, and updated and improved to the model cycle library, which improves the accuracy of trial production plan scheduling and the efficiency of multi-level linkage plan management and control.

[0169] Correspondingly, the present invention further provides a multi-level linkage planning control device.
