[0042] S101: Acquire a shipbuilding task object, and generate a plurality of first work packages according to the shipbuilding task object and the shipbuilding task type.

[0043] The obtaining of the shipbuilding task object is specifically:

[0044] The shipbuilding task object basic library is compiled based on the shipbuilding intermediate product segmentation, area, system, etc., and the hierarchical structure of the shipbuilding task object is used as the WBS (Work Breakdown Structure); according to the shipbuilding task object basic library, the shipbuilding task object is obtained. As can be seen from the above, the shipbuilding task object is a task object in the shipbuilding process.

[0045] In this embodiment, the generating of a plurality of first work packages according to the shipbuilding task object and the shipbuilding task type is specifically as follows:

[0046] After associating the shipbuilding task object with the corresponding multiple shipbuilding task types according to multiple standard processes, multiple first work packages are generated. Among them, multiple shipbuilding task types are associated with each shipbuilding task object, and each shipbuilding task type corresponds to a sub-work package, so each shipbuilding task object corresponds to multiple sub-work packages. The first work package is a modular work package / template work package, and the modular work package includes: a collection of multiple sub-work packages corresponding to each shipbuilding task object. Furthermore, the first work package is used as the WP in the WBS (WBS corresponds to the decomposition of the task object, and WP corresponds to the task type under the final task object).

[0047] S102: configuring attributes of a plurality of first work packages according to the shipbuilding task type, and generating a first database according to the first work packages and their attributes.

[0048] The attribute includes the duration of the first work package. Specifically, the duration of the first work package is the time required to complete the first work package.

[0049] In a specific embodiment, the attributes further include: the code, name and management data of the first work package, wherein the management data includes: responsible department, task stage, area type, acceptance grade, acceptance stage, control level, etc.

[0050] S103: after obtaining a plurality of second work packages and their attributes according to the first preset shipbuilding plan and the first database, the shipbuilding plan time is calculated according to the plurality of second work packages and their attributes.

[0051] Among them, the shipbuilding plan time is: the time required to complete the first preset shipbuilding plan is the shipbuilding production plan schedule.

[0052] Furthermore, the obtaining of the plurality of second work packages is specifically as follows: according to the first preset shipbuilding plan, a plurality of first work packages and their attributes are selected from the first database, the plurality of first work packages are selected as the plurality of second work packages, and the plurality of second work packages and their attributes are obtained.

[0053] In this embodiment, the shipbuilding plan time is calculated according to the plurality of the second work packages and their attributes, specifically:

[0054] After selecting a plurality of the first work packages from the first database according to the first object, generating the second work package; wherein the first object is a shipbuilding task object in the first preset shipbuilding plan;

[0055] After obtaining the preset completion time of the first object, the shipbuilding plan time is calculated by combining the attributes of multiple second work packages.

[0056] Furthermore, the logical relationship between the second work packages is obtained, specifically:

[0057] According to the shipbuilding task type, configure the order of completion of multiple second work packages, form the logical relationship between the second work packages and obtain them. Among them, the logical relationship includes: FS, FF, SS, etc. S means start, F means completion, then FS means that after the previous work package is completed, the next work package is completed. Each work package can select multiple previous work packages or multiple next work packages as needed. You can also select multiple work packages, and after configuring the logical relationship in batches, perform loop detection through the program to avoid dead loops when calculating the planned time of work packages.

[0061] Among them, the preset completion time of the first object is used to ensure that the first object can be manufactured before the critical time node. Therefore, the offset days should be set to ensure that the manufacturing of the first object is completed on time. For example, there are multiple first objects in the first preset shipbuilding plan, and each of the first objects has a corresponding critical time node. The critical time node of a first object is September 30, 2021, and the offset days are 5 days. Then the preset completion time of the first object is September 25, 2021, to ensure that the first object can be manufactured before the critical time node.

[0062] In a specific embodiment, the obtaining of the preset completion time of the first object and the calculation of the shipbuilding plan time in combination with the attributes of the plurality of the second work packages are specifically as follows:

[0063] Since each first object includes multiple second work packages, and each first object has a corresponding preset completion time. Therefore, the corresponding preset completion time of each first object is used as a hard constraint, and the properties of the multiple second work packages contained in each first object (mainly the construction period and logical relationship), the work calendar and the preset algorithm are combined to calculate the planned time of each second work package. The planned time of the second work packages in all first objects constitutes the shipbuilding planned time. Among them, the planned time of each second work package includes: the planned start time and the planned completion time of the work package.

[0064] Among them, the working calendar can be calculated based on the different schedules of different shipyards.

The prototype ship is the ship numbered 1, which is manufactured according to the first preset shipbuilding plan. After copying the first preset shipbuilding plan and making corresponding adjustments, multiple ships with N numbers are obtained and manufactured according to multiple ship-building plans, which can effectively improve shipbuilding efficiency. N is a positive integer greater than 1.

[0069] Furthermore, the shipbuilding task objects in the plurality of single-ship shipbuilding plans are adjusted respectively according to preset conditions, specifically: the shipbuilding task objects in the single-ship shipbuilding plan are added, deleted, modified, etc. according to the preset conditions, and the work packages and attributes (mainly logical relationships and construction periods) of the shipbuilding task objects are adjusted accordingly.

[0070] In a specific embodiment, it also includes:
