Description

Technical Field

[0001] This invention relates to the field of automobile manufacturing technology, specifically to a method, apparatus, system, and electronic equipment for setting standard working hours in vehicle manufacturing. Background Technology

[0002] Standard man-hours for vehicle manufacturing are core foundational data for automakers' capacity planning, production cost accounting, production line manpower allocation, process cycle optimization, and performance evaluation. Currently, there are three major technical pain points in setting man-hours for vehicle factories: First, the traditional stopwatch timing method relies on manual timing on site, which is greatly affected by the operator's skill level, working environment, and human error. It has poor repeatability. In the pre-research stage of new vehicles, there are no physical objects or work data, so it is impossible to establish a working time benchmark in advance. It can only rely on experience to estimate, and the deviation of working time data generally exceeds 18%.

[0003] Second, existing general MTM (predetermined time method) applications are mostly simple applications for single processes and single parts, without layered combination optimization for complex scenarios involving multiple processes, multiple materials, and multiple postures of the whole vehicle. Directly applying general time values ​​will result in problems such as mismatch of working conditions, omission of special operation actions, and distortion of the working time of the whole vehicle linkage, and it is impossible to form a unified working time benchmark system for the whole vehicle.

[0004] Third, the current industry's time management system lacks standardized combination logic. The statistical standards for time management in various process sections are not uniform. The time management for stamping, welding, painting, and final assembly is calculated independently, making it impossible to achieve data integration of time management for the entire vehicle. This results in inaccurate capacity matching analysis, rough breakdown of manufacturing costs, and a lack of precise data support for the planning of new factory IE (Industrial Engineering), which seriously restricts the implementation of the lean production system for the entire vehicle.

[0005] In summary, existing vehicle manufacturing time setting technologies suffer from low accuracy, poor versatility, inability to perform pre-modeling, and lack of integration across all processes. The industry urgently needs a high-precision time setting method that is compatible with the entire vehicle manufacturing process, based on standardized action combinations, and adaptable to different working conditions. Summary of the Invention

[0006] In view of this, it is necessary to provide a method, device, system and electronic equipment for setting standard time for vehicle manufacturing, in order to solve the technical problems of low accuracy, poor universality, inability to perform pre-modeling and lack of continuity across the entire process in the existing vehicle time setting technology.

[0007] To address the aforementioned problems, in a first aspect, the present invention provides a method for setting standard working hours in vehicle manufacturing, comprising: Determine the standard time values ​​for each basic motion unit in the entire vehicle manufacturing process; The standard time values ​​of each basic motion unit are chained together to obtain the basic working time for a single step operation. The basic working hours of all single-step operations in the same process are superimposed and combined to obtain the combined basic working hours. The combined basic working hours are then corrected according to the working conditions of the process to obtain the process reference working hours. Based on the process operation mode, the process baseline time is reorganized and optimized to eliminate process action overlap error and obtain the section baseline time; A unified standard for the benchmark working hours of each section of the vehicle is established to determine the standard working hours for the entire vehicle.

[0008] In one possible implementation, the standard time value of each basic motion unit in the entire vehicle manufacturing process is determined, including: The entire process of vehicle manufacturing is structurally broken down to obtain the standardized work content of each process; Based on the MTM standard motion library, the standardized work content of each process is broken down into multiple basic motion units, and the standard time value of each basic motion unit is determined.

[0009] In one possible implementation, the entire vehicle manufacturing process is structurally broken down to obtain standardized work content for each process, including: The parts are disassembled in a hierarchical order of vehicle, section, process, and operation steps. Invalid waiting and redundant actions are eliminated from the disassembled parts, and pure value-added operations are retained to obtain the standardized operation content of each process.

[0010] In one possible implementation, the combined basic time is modified according to the work process conditions to obtain the work process reference time, including: Based on preset material coefficients, environmental coefficients, and compliance operation allowance time, the combined basic working hours are modified to obtain the process baseline working hours; The material coefficient is determined based on the weight, size, and assembly difficulty of the parts, while the environmental coefficient is determined based on the temperature and humidity of the workshop, the working height, and the degree of confinement of the space.

[0011] In one possible implementation, the combined base time is modified based on preset material coefficients, environmental coefficients, and compliance work allowance time to obtain the process baseline time, including: The product obtained by multiplying the combined basic working hours by the preset material coefficient and environmental coefficient in sequence, and then adding the compliant operation allowance time, yields the process baseline working hours.

[0012] In one possible implementation, the method for setting standard working hours for vehicle manufacturing also includes: Obtain batch trial production data based on the standard working hours of the entire vehicle, and remove abnormal working hours from the standard working hours of the entire vehicle based on the batch trial production data to obtain the corrected standard working hours of the entire vehicle.

[0013] In one possible implementation, the baseline time of the process is reorganized and optimized based on the process operation mode, including: Based on the process operation modes of parallel and / or sequential processes, the baseline working time of the process is reorganized and optimized.

[0014] Secondly, the present invention also provides a standard time setting device for vehicle manufacturing, comprising: The basic motion timing value determination module is used to determine the standard timing value of each basic motion unit in the entire process of vehicle manufacturing; The single-step operation time determination module is used to combine the standard time values ​​of each basic motion unit in series to obtain the basic time of the single-step operation. The process baseline time determination module is used to superimpose and combine the basic time of all single-step operations in the same process to obtain the combined basic time, and to correct the combined basic time according to the process operation conditions to obtain the process baseline time. The section baseline working time determination module is used to reorganize and optimize the process baseline working time based on the process operation mode in order to eliminate process action overlap error and obtain the section baseline working time. The whole vehicle work time determination module is used to unify the benchmark work time of each section of the whole vehicle and determine the standard work time of the whole vehicle.

[0015] Thirdly, the present invention also provides an electronic device, including a memory and a processor, wherein, The memory is used to store programs; The processor, coupled to the memory, is used to execute the program stored in the memory to implement the steps of the vehicle manufacturing standard time setting method as described in any of the preceding claims.

[0016] Fourthly, the present invention also provides a standard time setting system for vehicle manufacturing, comprising: the aforementioned electronic device and a human-machine interaction device communicatively connected to the electronic device, wherein the human-machine interaction device is used to receive input of the entire process of vehicle manufacturing.

[0017] The beneficial effects of adopting the above implementation method are as follows: The method, device, system and electronic equipment for setting standard working hours for vehicle manufacturing provided by the present invention determine the standard time value of each basic action unit in the entire process of vehicle manufacturing; the standard time values ​​of each basic action unit are combined in series to obtain the basic working hours of a single step operation; all the basic working hours of a single step operation in the same process are superimposed and combined to obtain the combined basic working hours, and the combined basic working hours are corrected according to the working conditions of the process operation to obtain the process reference working hours; based on the process operation mode, the process reference working hours are reorganized and optimized to eliminate the error of overlapping process actions to obtain the section reference working hours; and the standard working hours of the section reference working hours corresponding to each section of the vehicle are standardized to determine the standard working hours of the entire vehicle.

[0018] This invention abandons the traditional mode of directly taking values ​​from a single action. Instead, it breaks down the entire vehicle manufacturing process into layers, such as basic action units, processes, sections, and the whole vehicle, and determines the working time layer by layer. First, it determines the basic working time for a single step, then determines the benchmark working time for the process based on the basic working time for the single step, then determines the benchmark working time for the section, and finally obtains the standard working time for the entire vehicle. This invention adopts a unique five-step process: process decomposition, action unit splitting, layered combination modeling, multi-dimensional working condition correction, and overall vehicle working time summary and calibration. This process achieves accurate and unified setting of standard working times for the four major processes of the whole vehicle, solving the technical problems of low accuracy, poor universality, inability to perform pre-modeling, and lack of integration across the entire process in existing vehicle working time setting technologies.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] In the description of the embodiments of this application, unless otherwise stated, "a plurality of" means two or more.

[0023] In this embodiment of the invention, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, apparatus, product or device that includes a series of steps or modules is not necessarily limited to those steps or modules that are explicitly listed, but may include other steps or modules that are not explicitly listed or that are inherent to such process, method, product or device.

[0024] The naming or numbering of steps in the embodiments of the present invention does not mean that the steps in the method flow must be executed in the time / logical order indicated by the naming or numbering. The execution order of the named or numbered process steps can be changed according to the technical purpose to be achieved, as long as the same or similar technical effect can be achieved.

[0025] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] This invention provides a method, apparatus, system, and electronic device for setting standard working hours in vehicle manufacturing, which will be described below.

[0027] This invention provides a method for setting standard working hours in vehicle manufacturing, which can be implemented by executing an application program on a computer device; such as Figure 1 As shown, the method includes: S101. Determine the standard time value of each basic motion unit in the entire process of vehicle manufacturing.

[0028] It is understandable that the basic action units in the entire process of vehicle manufacturing are different, such as reaching out, grasping, transporting, positioning, aligning, tightening, fitting, releasing, and walking. These basic action units cannot be further divided.

[0029] S102. Connect and combine the standard time values ​​of each basic motion unit to obtain the basic working time of a single-step operation.

[0030] It is understood that this invention no longer simply retrieves the MTM standard time value, but instead performs layered combination matching based on the vehicle operation logic. The layers include: basic layer, process layer, section layer, and vehicle layer. The basic layer concatenates and combines the standard time values ​​of each basic action unit to obtain the basic working time for a single step operation.

[0031] S103. The basic working hours of all single-step operations in the same process are superimposed and combined to obtain the combined basic working hours. The combined basic working hours are then corrected according to the working conditions of the process to obtain the process reference working hours.

[0032] Understandably, the process layer combines the time of all steps within the same process, matching the process operation logic to generate the process baseline time. The core of the process operation logic in vehicle manufacturing follows the main line of four major processes that are sequentially advanced and interconnected, with clear sequential dependencies between each process. The processes include, in order: stamping, welding, painting, and final assembly.

[0033] S104. Based on the process operation mode, the process baseline time is reorganized and optimized to eliminate process action overlap error and obtain the section baseline time.

[0034] Understandably, process operation modes include parallel and sequential modes. The sequential mode refers to breaking down the entire vehicle development / production process into independent stages such as requirements analysis, product design, process design, stamping, welding, painting, and final assembly, with the next stage only starting after the previous one is 100% complete. The parallel mode, also known as concurrent engineering, breaks down departmental barriers and organizes cross-team involvement from design, process, quality, and supply chain teams in the early stages of vehicle development, allowing processes that would otherwise be performed sequentially to be processed in parallel as much as possible.

[0035] S105. Standardize the benchmark working hours for each section of the vehicle and determine the standard working hours for the entire vehicle.

[0036] Understandably, standardizing the benchmark working hours for each section of the vehicle manufacturing process solves the problems of inconsistent working hour standards across different sections, making horizontal comparison impossible and causing inaccurate production capacity calculations.

[0037] This invention provides a method for accurately setting the standard working time for the entire vehicle process through action unit decomposition, layered combination modeling, and adaptive correction of working conditions. It is applicable to the four major processes of vehicle stamping, welding, painting, and final assembly, as well as the scenario of establishing working time benchmarks before mass production of new vehicles.

[0038] In some embodiments, determining the standard time value of each basic motion unit in the entire vehicle manufacturing process includes: The entire process of vehicle manufacturing is structurally broken down to obtain the standardized work content of each process; Based on the MTM standard motion library, the standardized work content of each process is broken down into multiple basic motion units, and the standard time value of each basic motion unit is determined.

[0039] Understandably, relying on the MTM standard motion library, the work actions of each process are broken down into basic motion units that cannot be further divided, such as reaching out, grasping, moving, positioning, aligning, tightening, fitting, releasing, and walking, and the standard time value of each motion unit is recorded.

[0040] The MTM standard motion library is a set of basic motion units that are pre-determined and standardized in the Methods-Time Measurement (MTM) system, with each motion unit corresponding to a fixed time value.

[0041] In some embodiments, the entire vehicle manufacturing process is structurally broken down to obtain standardized work content for each process, including: The parts are disassembled in a hierarchical order of vehicle, section, process, and operation steps. Invalid waiting and redundant actions are eliminated from the disassembled parts, and pure value-added operations are retained to obtain the standardized operation content of each process.

[0042] Understandably, with the four core processes of vehicle stamping, welding, painting, and final assembly as the core, all standardized operations are broken down into four levels: "vehicle-section-process-operation step," and all non-value-adding actions are streamlined. Ineffective waiting and redundant movement are eliminated, retaining only pure value-adding processes to form a standardized operation list for the entire vehicle. This list clarifies the operating environment, material specifications, operating posture, and equipment matching conditions for each process, establishing a scenario benchmark for MTM (Manufacturing Module) action matching.

[0043] In some embodiments, the combined basic time is modified according to the process operation conditions to obtain the process reference time, including: Based on preset material coefficients, environmental coefficients, and compliance operation allowance time, the combined basic working hours are modified to obtain the process baseline working hours; The material coefficient is determined based on the weight, size, and assembly difficulty of the parts, while the environmental coefficient is determined based on the temperature and humidity of the workshop, the working height, and the degree of confinement of the space.

[0044] It is understandable that this embodiment is designed for the complex working conditions of vehicle manufacturing. It introduces material coefficients, environmental coefficients, and compliance operation allowance time to accurately calibrate the combined basic working time and avoid the defects of general MTM model working condition adaptation.

[0045] In some embodiments, the combined base time is modified based on preset material coefficients, environmental coefficients, and compliance work allowance time to obtain the process baseline time, including: The product obtained by multiplying the combined basic working hours by the preset material coefficient and environmental coefficient in sequence, and then adding the compliant operation allowance time, yields the process baseline working hours.

[0046] It is understandable that the standard working time for a process (also known as the standard working time for a process) = the base working time of the MTM combination. Material coefficient Environmental factors + lenient time for compliant operations.

[0047] The grace period for compliant operations can be obtained by multiplying a preset baseline time by a reasonable grace coefficient that takes into account the differences in operations between new and experienced workers in mass production.

[0048] In some embodiments, the method for setting standard working hours for vehicle manufacturing further includes: Obtain batch trial production data based on the standard working hours of the entire vehicle, and remove abnormal working hours from the standard working hours of the entire vehicle based on the batch trial production data to obtain the corrected standard working hours of the entire vehicle.

[0049] Understandably, after completing the calculation of time for a single process and a single work section, a preliminary standard time for the entire vehicle is generated. Through reverse verification using small-batch trial production data on-site, abnormal time data is eliminated. This includes abnormal time in the standard time for the entire vehicle and its corresponding abnormal process time and abnormal work section time. The parameters of the combined model are then corrected, and the calculation rules, splitting standards, and lenient benchmarks for the four major processes of the entire vehicle are unified. Ultimately, a reusable, iterative, and factory-wide unified standard time system for vehicle manufacturing is formed.

[0050] In some embodiments, the baseline time of the process is reorganized and optimized based on the process operation mode, including: Based on the process operation modes of parallel and / or sequential processes, the baseline working time of the process is reorganized and optimized.

[0051] Understandably, the work section level combines parallel and sequential operation modes of processes to optimize work time reorganization and eliminate errors caused by overlapping process actions.

[0052] The error here refers to overlapping of process actions. For example, when two parallel processes or multiple parallel and serial processes overlap in time, in order to reduce the error and avoid repeated calculations, reorganization optimization is required. The overlapping time only needs to be calculated once.

[0053] In some embodiments, the present invention provides a method for setting standard working hours for vehicle manufacturing based on the combination of MTM action units, which solves the industry pain points of large errors in traditional working hour calculation, inability to model new vehicles in advance, inconsistent working hours for multiple processes of the whole vehicle, and poor adaptability to special working conditions. It realizes the standardization, accuracy, advance and traceability of working hours for the whole vehicle process, and provides accurate benchmark data for process planning, capacity accounting, cost control and lean improvement of new factories.

[0054] This embodiment relies on the MTM-UAS (MTM Advanced Process Module System) universal motion analysis system, abandoning the traditional mode of directly taking values ​​from single motions. It adopts a unique five-step process: process decomposition, motion unit splitting, layered combination modeling, multi-dimensional working condition correction, and vehicle time summary calibration. This process achieves accurate and unified setting of standard working hours for the four major processes of the vehicle. The specific steps are as follows: Step 1: Structured disassembly of the entire vehicle manufacturing process.

[0055] Centered on the four major processes of vehicle stamping, welding, painting, and final assembly, and broken down into four levels—"vehicle-section-process-operation step"—all standardized operations are streamlined. Ineffective waiting and redundant movement are eliminated, retaining only pure value-added processes to create a standardized vehicle operation list. This list clarifies the operating environment, material specifications, operating posture, and equipment matching conditions for each process, establishing a scenario benchmark for MTM (Manufacturing Module) action matching.

[0056] Step 2: Minimum Action Unit Decomposition Based on MTM.

[0057] Based on the MTM standard motion library, each process operation is broken down into indivisible basic motion units such as reaching, grasping, moving, positioning, aligning, tightening, fitting, releasing, and walking, and the standard time value of each motion unit is recorded. Unlike traditional coarse decomposition, this invention refines differentiated motion decomposition rules for special scenarios such as heavy-duty vehicle handling, high-altitude operations, precision assembly, and welding positioning, and supplements the special motion units specific to the whole vehicle.

[0058] Step 3: Create a unique layered action unit combination model.

[0059] This invention no longer simply retrieves the MTM standard time value, but instead performs layered combination matching based on the overall vehicle operation logic: The basic layer connects and combines multiple basic action units of a single step to form the basic working time for a single step operation; At the process level, the time of all work steps in the same process is superimposed and combined, matched with the process operation logic, to generate the process baseline time. At the work section level, time reorganization and optimization are carried out by combining parallel and serial operation modes of processes to eliminate errors caused by overlapping actions in processes; At the vehicle level, the working hours of the four major process sections are integrated, statistical standards are unified, and a standard working hour database for the entire vehicle is established.

[0060] Step 4: Multi-condition adaptive coefficient correction.

[0061] To address the complex operating conditions of vehicle manufacturing, a three-dimensional correction coefficient is introduced to accurately calibrate the combined basic operating time, thus avoiding the shortcomings of the general MTM model in adapting to operating conditions. Material coefficient, adjusted based on part weight, size, and assembly difficulty; Environmental factors are used to fine-tune working hours based on workshop temperature and humidity, working height, and confined space. The proficiency coefficient should be set with a reasonable leniency factor, taking into account the differences in operation between new and experienced workers in mass production. Final formula: Standard working time for a process = MTM combined basic working time Material coefficient Environmental factors + lenient time for compliant operations.

[0062] Step 5: Vehicle labor time verification and standardization.

[0063] After completing the time calculation for a single process and a single work section, the abnormal time data is verified by reverse verification through small-batch trial production data on site. Abnormal time data is eliminated, the parameters of the combined model are corrected, and the time calculation rules, splitting standards, and lenient benchmarks for the four major processes of the whole vehicle are unified. Finally, a reusable, iterative, and factory-wide unified standard time system for whole vehicle manufacturing is formed.

[0064] The present invention has the following beneficial effects: 1. Calculation accuracy has been greatly improved. Compared to the error of over 18% in traditional stopwatch timing methods, this invention controls the error of vehicle process timing tests to within 3% through standardized action combinations and adaptive correction of working conditions, significantly improving the accuracy of timing data.

[0065] 2. Implement pre-planning of new vehicle manufacturing processes. Without relying on mass production and trial production, the time system can be established during the construction of new factories and the development of new car projects, supporting production line cycle design, manpower allocation, equipment selection, and cost budgeting in advance, and significantly shortening the preparation cycle for mass production of new cars.

[0066] 3. Unify lean management standards across the entire group This will enable the standardization of time requirements and data sharing across the four major processes of vehicle manufacturing, providing a unified and traceable technical benchmark for capacity load analysis, production efficiency improvement, process improvement, performance evaluation, and refined control of production costs.

[0067] 4. The model has strong iterative reusability. The MTM motion unit combination model can be quickly iterated and adapted to new models and new processes without the need to repeatedly build a testing system, which greatly reduces the cost of building and maintaining the car company's work hour system and adapts to multiple models and multiple batches of vehicle production modes.

[0068] In some embodiments, taking a vehicle assembly chassis line as an example, the method of the present invention is used to set the working hours: The process breakdown of the engine assembly process is divided into seven steps: part removal, handling, positioning, docking, bolt tightening, inspection, and resetting. Action decomposition involves breaking down each step into the smallest standard action unit of MTM and retrieving the standard time value of each unit. Layered combination, linking the time values ​​of each action unit, and superimposing the step time to form the basic combination time of the process; The working conditions are adjusted, taking into account the material coefficient of large components in engine assembly, the tight working environment coefficient of the final assembly workshop, and the relaxation of standard operations, to calculate the final standard working hours; After verification and on-site testing, the calculated working hours deviated from the actual optimal working hours by only 2.7%, which is far better than the traditional calculation method and can be directly used for production line cycle planning and manpower allocation.

[0069] Simultaneously, this combined method was applied to core processes such as welding of the vehicle body, inspection of the paint finish, and stamping of parts, achieving high-precision time verification in all of them, and successfully establishing a brand-new standard time system for the entire vehicle in the factory.

[0070] The key innovations of this invention include: 1. Unique hierarchical MTM combined modeling logic for the entire vehicle Breaking through the limitations of existing MTMs which are only applicable to single-process calculations, we have pioneered a four-layer combination algorithm of "action unit-process-section-vehicle", which upgrades from single action value acquisition to systematic combination modeling and solves the industry problem of inconsistent time for multiple processes in the whole vehicle.

[0071] 2. Vehicle-specific adaptive correction system for specific operating conditions Unlike the general MTM fixed time value mode, it establishes a dedicated correction coefficient library for special scenarios such as vehicle welding, painting, heavy assembly, and precision operations, to solve the defects of mismatch between the general model and the vehicle manufacturing conditions and large calculation deviations.

[0072] 3. New vehicle pre-production time modeling capability Based on pure motion unit combination calculations, without relying on mass production site data, the time frame can be set up in advance during the new vehicle SE synchronous engineering and factory planning stages, realizing the pre-positioning of time frame standards and filling the technical gap of no accurate time frame benchmark in the new vehicle pre-research stage.

[0073] 4. A unified and standardized time system for the entire process. The unified rules for the breakdown, calculation, leniency, and summarization of the four major processes of stamping, welding, painting, and general assembly completely solve the problems of inconsistent time standards for different work sections, inability to make horizontal comparisons, and inaccurate capacity calculations.

[0074] like Figure 2 As shown, the present invention also provides a standard time setting device 200 for vehicle manufacturing, comprising: The basic motion time value determination module 201 is used to determine the standard time value of each basic motion unit in the entire process of vehicle manufacturing. The single-step operation time determination module 202 is used to connect and combine the standard time values ​​of each basic motion unit to obtain the basic time of the single-step operation. The process baseline time determination module 203 is used to superimpose and combine the basic time of all single-step operations in the same process to obtain the combined basic time, and to correct the combined basic time according to the process operation conditions to obtain the process baseline time. The section baseline working time determination module 204 is used to reorganize and optimize the process baseline working time based on the process operation mode to eliminate process action overlap error and obtain the section baseline working time. The whole vehicle working time determination module 205 is used to unify the standard working time of each section of the whole vehicle and determine the standard working time of the whole vehicle.

[0075] The present invention also provides an electronic device, including a memory and a processor, wherein, The memory is used to store programs; The processor, coupled to the memory, is used to execute the program stored in the memory to implement the steps of the vehicle manufacturing standard time setting method as described in any of the preceding claims.

[0076] The present invention also provides a standard time setting system for vehicle manufacturing, comprising: the aforementioned electronic device and a human-machine interaction device communicatively connected to the electronic device, wherein the human-machine interaction device is used to receive input of the entire process of vehicle manufacturing.

[0078] like Figure 3 As shown, the present invention also provides an electronic device 300. The electronic device 300 includes a processor 301, a memory 302, and a display 303. Figure 3Only some components of the electronic device 300 are shown, but it should be understood that it is not required to implement all of the components shown, and more or fewer components may be implemented instead.

In other embodiments, memory 302 may also be an external storage device of electronic device 300, such as a plug-in hard disk, smart media card (SMC), secure digital (SD) card, flash card, etc. equipped on electronic device 300.

[0080] Furthermore, the memory 302 may include both internal storage units of the electronic device 300 and external storage devices. The memory 302 is used to store application software and various types of data installed on the electronic device 300.

[0081] In some embodiments, processor 301 may be a central processing unit (CPU), microprocessor, or other data processing chip, used to run program code stored in memory 302 or process data, such as the method for setting standard working hours for vehicle manufacturing in this invention.

[0083] In some embodiments of the present invention, when the processor 301 executes the vehicle manufacturing standard time setting program in the memory 302, the following steps can be implemented: Determine the standard time values ​​for each basic motion unit in the entire vehicle manufacturing process; The standard time values ​​of each basic motion unit are chained together to obtain the basic working time for a single step operation. The basic working hours of all single-step operations in the same process are superimposed and combined to obtain the combined basic working hours. The combined basic working hours are then corrected according to the working conditions of the process to obtain the process reference working hours. Based on the process operation mode, the process baseline time is reorganized and optimized to eliminate process action overlap error and obtain the section baseline time; A unified standard for the benchmark working hours of each section of the vehicle is established to determine the standard working hours for the entire vehicle.

[0084] It should be understood that when the processor 301 executes the vehicle manufacturing standard time setting program in the memory 302, in addition to the functions mentioned above, it can also perform other functions, as can be found in the description of the corresponding method embodiments above.
