Description

Technical Field

[0001] This invention relates to the field of shipbuilding data processing, and in particular to a method and system for managing data throughout the entire process of ship design change orders. Background Technology

[0002] Ship design change orders are modifications made to address various issues arising during the design and construction of ships, ensuring that the products meet functional specifications, improve quality, or reduce costs. Currently, the actual data management of design change orders suffers from inefficient methods such as manual judgment during procurement applications and manual dispatch of change orders to construction personnel. Furthermore, production-related data is primarily recorded on paper by construction staff. There is an urgent need for a systematically planned, information-based management approach to achieve comprehensive data management of design change orders across the entire process from design, procurement, operation, production, and quality control, thereby addressing the pain points of data silos and untimely data transmission in business processes. Summary of the Invention

[0003] In view of the shortcomings of the prior art described above, the present invention provides a method for full-process data management of ship design change orders, comprising the following steps:

[0004] S1. Organize the standard data involved in the entire process of design change order data management, build a standard database for data maintenance, and the standard data includes: pallet type and pallet production cycle data;

[0005] S2. Organize and input the design data involved in the entire process of design change order data management into the design data module; the design data includes: project number, change order number, change order stage, original drawing number corresponding to the change order, tray number, tray type, and change order issuance time;

[0006] S3. Organize and input the procurement data involved in the entire process of design change order data management into the procurement data module. The procurement data includes the department that requires pallets and the planned delivery time of the pallets; read the project number, change order number and pallet number stored in the design data module.

[0007] S4. Modification of single material application judgment; specifically including:

[0008] S41 reads the tray type of the relevant change order in the design data module based on the change order number;

[0009] S42 reads the pallet production cycle corresponding to the pallet type in the standard database based on the pallet type;

[0010] S43 reads the change order issuance time corresponding to the relevant change order number in the design data module; and determines the time based on the change order issuance time, the planned pallet delivery time, and the standard pallet production cycle.

[0011] The rules for determining single material applications have been changed as follows:

[0012] If the change order issuance time for order number α - the planned delivery time of the pallet for order number α < the standard production cycle of the pallet for order number α, it is determined that the original pallet should be inserted, and the materials on the original pallet should be adjusted accordingly.

[0013] If the change order issuance time for order number α minus the planned pallet delivery time for order number α is greater than or equal to the standard pallet production cycle for order number α, it is considered a re-request for delivery, and a new pallet will be created to meet the change requirement.

[0014] Optionally, the following steps may also be included:

[0015] S5. Organize and input the operational data involved in the entire process of design change order data management into the operational data module. The operational data includes the original drawing work package number, the original drawing work package status, and the actual working hours of the original drawing work package; read the project number, change order number, change order stage, and the original drawing number corresponding to the change order stored in the design data module.

[0016] S6. Change Order Rejection / Return Judgment. Based on the change order number, read the actual start time of the corresponding original drawing work package in the runtime data module and make a judgment;

[0017] Change the rules for determining rejection / return:

[0018] If the original drawing work package with change number α is not empty when it is actually started, then it is determined as yes;

[0019] If the actual work session of the original drawing work package with change number α is empty, then the result is considered negative.

[0020] Optionally, the following steps may also be included:

[0021] S7. Modify single dispatch determination; including:

[0022] S71 reads the corresponding change order stage from the design data module based on the change order number;

[0023] S72 reads the corresponding change order material application judgment from step S4 based on the change order number;

[0024] S73 makes a determination based on the change order stage and change order material application judgment of the relevant change order number; the rules for change order dispatch judgment are as follows: if the change order material application judgment for change order number α is to insert the original pallet or the change order stage for change order number α is detailed design, then it is judged as no; if the change order material application judgment for change order number α is to re-apply for delivery or the change order stage for change order number α is production design, then it is judged as yes.

[0025] Optionally, the following steps may also be included:

[0026] S8. Change order construction department judgment: Based on the change order number, read the status of the corresponding original drawing work package in the running data module and make a judgment;

[0027] Change the rules for determining the construction department:

[0028] If the status of the original drawing work package with change number α is "not started", then the construction department is determined to be the department responsible for the original drawing work package.

[0029] If the status of the original work package with order number α is changed to "started", then the construction department is determined to be manually involved.

[0030] Optionally, the following steps may also be included:

[0031] S9. Based on the determination result of the construction department in step S8, enter the construction department data for the change order.

[0032] Optionally, the following steps may also be included:

[0033] S10. Organize and input the production data involved in the entire process data management of design change orders into the production data module. The production data includes the construction work area of ​​the change order work package, the construction team of the change order work package, the actual working hours of the change order work package, the actual start time of the change order work package, and the actual end time of the change order work package; read the project number, change order number, and change order construction department stored in the operation data module.

[0034] Optionally, the following steps may also be included:

[0035] S11. Organize and input the quality data involved in the entire process of design change order data management into the quality data module; read the project number, change order number, change order construction department, change order work package actual working hours, change order work package actual start time, and change order work package actual end time stored in the production data module. The quality data includes change order quality confirmation.

[0036] The present invention also provides a data management system for the entire process of ship design change orders, wherein the data management system is used to implement the data management method described above.

[0037] Optionally, the data management system includes:

[0038] The standard data module is used to maintain the standard database involved in the entire data management process of design change orders.

[0039] The design data module is used to realize the input and management of data involving the design end in the whole process of design change order data management;

[0040] The procurement data module is used to input and manage the procurement-related data in the entire data management process of design change orders.

[0043] The quality data module is used to input and manage the quality-related data in the entire data management process of design change orders.

[0044] As described above, this invention provides a method and system for managing data throughout the entire process of ship design change orders. The method includes: constructing a standard database and maintaining standard data; inputting design data, procurement data, operational data, production data, and quality data; calculating and determining change order material requests based on change order issuance time, pallet planned delivery time, and pallet standard manufacturing cycle; determining change order work assignment based on change order material request judgment and change order stage; and determining the change order construction department and scrap / return determination based on original drawing work package number, original drawing work package status, and original drawing work package actual work commencement time. This data management method integrates data specifications and relationships across all stages, including design, procurement, production, operation, and quality, enabling full-process data input and management of design change orders. This ensures that all relevant data can be synchronously transferred and compared when changes occur, ensuring close collaboration among design, procurement, production, and quality stages during the change process, significantly improving the overall efficiency of shipbuilding and project management level. Attached Figure Description

[0045] Figure 1 The flowchart shown is a complete data management method flowchart of this invention.

[0046] Figure 2 The diagram shown is an architecture diagram of the end-to-end data management system in this invention. Detailed Implementation

[0047] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0048] It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of the present invention. Therefore, the illustrations only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0049] like Figure 1 As shown, this invention provides a method for managing data throughout the entire process of ship design change orders, comprising the following steps:

[0050] S1. Organize the standard data involved in the entire process of design change order data management, build a standard database for data maintenance, and the standard data includes: pallet type and pallet production cycle data;

[0051] S2. Organize and input the design data involved in the entire process of design change order data management into the design data module; the design data includes: project number, change order number, change order stage, original drawing number corresponding to the change order, tray number, tray type, and change order issuance time;

[0052] S3. Organize and input the procurement data involved in the entire process of design change order data management into the procurement data module. The procurement data includes the department that requires pallets and the planned delivery time of the pallets; read the project number, change order number and pallet number stored in the design data module.

[0053] S4. Modification of single material application judgment; specifically including:

[0054] S41 reads the tray type of the relevant change order in the design data module based on the change order number;

[0055] S42 reads the pallet production cycle corresponding to the pallet type in the standard database based on the pallet type;

[0056] S43 reads the change order issuance time corresponding to the relevant change order number in the design data module; and determines the time based on the change order issuance time, the planned pallet delivery time, and the standard pallet production cycle.

[0057] Changes to the single-item application judgment rules:

[0058] (Change order number α's order issuance time - Change order number α's pallet planned delivery time) < Change order number α's pallet standard production cycle, determined as "Insert original pallet"

[0059] (Order modification issuance time for order number α - planned pallet delivery time for order number α) >= standard pallet production cycle for order number α, then it is determined as "re-request delivery".

[0060] The core idea behind the judgment rule in this step is to determine how to handle change orders by calculating the time difference and comparing it with the standard production cycle. If the time difference between the change order issuance time and the planned delivery time is less than the standard production cycle, it means that the change order issuance time is close to the planned delivery time, and the remaining time is insufficient to remake a complete pallet for the change order. Therefore, the most efficient approach is to "insert" the change request into the already planned original pallet. This requires adjusting the composition of the original pallet's materials, adding or removing some items, without changing the overall delivery plan, thus helping to avoid delays and resource waste.

[0061] If the time difference between the change order issuance time and the planned delivery time is greater than or equal to the standard production cycle, it means that the change order issuance time is far from the planned delivery time, and there is enough time to remake the pallet. In this case, the system has sufficient time to respond to the change order, so a new delivery request can be submitted, i.e., a new pallet can be created to meet the change requirement.

[0062] Next, proceed to step S5: sort out the operational data involved in the entire process data management of design change orders, and enter it into the operational data module. The operational data includes the original drawing work package number, the original drawing work package status, and the actual working hours of the original drawing work package; read the project number, change order number, change order stage, and the original drawing number corresponding to the change order stored in the design data module;

[0063] S6. Change Order Rejection / Return Judgment. Based on the change order number, read the actual working hours of the corresponding original drawing work package in the running data module and make a judgment; here, the actual working hours of the original drawing work package refers to the working hours that the original drawing work package has actually been constructed.

[0064] Change the rules for determining rejection / return:

[0065] If the original drawing work package with change number α is not empty when it is actually started, then it is determined as yes;

[0066] If the actual work session of the original drawing work package with change number α is empty, then the result is considered negative.

[0067] Specifically, if the original work package is not empty when construction actually begins, it means that the original work package has already undergone substantial construction, and this change will render the completed portion invalid, thus requiring a rework. If the original work package is empty when construction actually begins, it means that the original work package has not undergone substantial construction, and there is no physical work to be discarded, thus requiring no rework.

[0068] S7. Modify the single dispatch determination.

[0069] S71 reads the corresponding "Change Order Stage" from the design data module based on the "Change Order Number";

[0070] S72 reads the corresponding "Change Order Material Request Judgment" from step S4 based on the "Change Order Number";

[0071] S73 makes a determination based on the "Change Order Stage" and "Change Order Material Request Judgment" of the relevant change order number; the rules for change order dispatch determination are as follows:

[0072] If the material request for change order number α is determined to be "insert original pallet" or the change order stage for change order number α is "detailed design", then it is determined as no.

[0073] If the material request for change order number α is determined to be "re-request delivery" or the change order stage for change order number α is "production design", then it is determined to be...

[0074] In this step, when the change order material request is determined to be "insert into existing pallet," it means that the material needs to be directly inserted into the existing pallet, which may involve inventory adjustments or minimizing changes, so no additional dispatching is required. Meanwhile, when the change order stage is "detailed design," it indicates that the change order is in the detailed design stage, usually involving design verification or drawing updates, and has not yet entered production execution; therefore, dispatching is not allowed.

[0075] Conversely, a change order material request classified as "re-request delivery" means that the material needs to be re-requested for delivery, possibly due to stockouts or changes in demand, thus requiring work assignment to handle the delivery task. A change order stage marked as "production design" indicates that the change order has entered the production design phase, typically involving process preparation or production scheduling, thus necessitating work assignment.

[0076] Next, proceed to step S8, the determination of the construction department for the change order. Based on the "Change Order Number," read the corresponding "Original Drawing Work Package Status" from the runtime data module and make a determination;

[0077] Change the rules for determining the construction department:

[0078] If the status of the original drawing work package with change number α is "not started", then the construction department is determined to be the "original drawing work package operation department". The work originally planned here has not yet started, and the drawings, materials, and manpower have not yet been put into the originally planned production or construction. The most efficient approach is to let the department originally responsible for this work (the original drawing work package operation department) directly take over this change task.

[0079] If the status of the original work package with order number α is changed to "Initiated", then the construction department is determined to be "Manually Determined". The planned work has already started; materials may have been cut, partial assembly may have been completed, or construction workers may already be on-site. This requires collaboration between the original work department, the on-site construction department, and even the quality inspection department to assess the impact and determine the leading department. Therefore, a construction department needs to be manually assigned after comprehensive judgment.

[0080] S9. Based on the "Change Order Construction Department Judgment" result in step S8, enter the "Change Order Construction Department" data.

[0081] S10. Organize and input the production data involved in the entire process of design change order data management into the production data module. The production data includes the construction work area of ​​the change order work package, the construction team of the change order work package, the actual working hours of the change order work package, the actual start time of the change order work package, and the actual end time of the change order work package; read the project number, change order number, and change order construction department stored in the operation data module.

[0082] S11. Organize and input the quality data involved in the entire process of design change order data management into the quality data module; read the project number, change order number, change order construction department, change order work package actual working hours, change order work package actual start time, and change order work package actual end time stored in the production data module. The quality data includes change order quality confirmation, that is, the final construction quality confirmation for each change order.

[0083] This invention also provides a data management system for the entire process of ship design change orders, used to implement the above-mentioned data management method. The system includes:

[0084] The standard data module is used to maintain the standard database involved in the entire data management process of design change orders.

[0085] The design data module is used to input and manage the data involved in the design process during the entire design change order data management workflow.

[0086] The procurement data module is used to input and manage the procurement-related data in the entire data management process of design change orders.
