Description

Technical Field

[0001] The present application relates to the technical field of shipbuilding, and in particular to a management method and system for quantitative disassembly of ship piping systems. Background Art

[0002] Modern shipbuilding generally adopts a regional construction model. After detailed and production design, the pipe segment model is roughly divided into multiple pallets according to the area. The pallets contain numerous pipe segments, ranging from a few to 500 or 600. Regardless of the quantity, each pallet is submitted to the pipe production unit for production and delivery on an agreed date. This relatively simple division method makes the pallets non-quantitative and non-qualitative, which also causes two problems:

[0003] One issue is inconsistent production planning. Pallets contain numerous pipe segments with varying characteristics, which can result in some segments being completed prematurely, occupying the site, or too late, impacting construction. Pallets contain a wide variety of pipe segments, and when submitted to the manufacturer for production, only the delivery date for the entire pallet is agreed upon. Due to factors such as raw material customization, such as the short production cycle for carbon segments and the long production cycle for alloy segments, the production cycles for different types of segments within a pallet vary significantly. Even if carbon segments can be completed ahead of time, they cannot be delivered as finished products for on-site installation.

[0004] Secondly, when the number of pipe sections on pallets is huge, delivery and installation schedules become difficult. Pallets need to be temporarily split into smaller groups and transported to designated areas in batches, making management difficult. Furthermore, with hundreds of pipe sections, construction workers struggle to quickly locate designated sections for installation, significantly impacting work efficiency.

[0005] In summary, it is necessary to provide an improved technical solution to address the above-mentioned deficiencies in the existing technology. Summary of the Invention

[0006] The purpose of the embodiments of the present application is to provide a management method and system for the quantitative disassembly of ship piping systems, which can reduce the impact of pallet production and distribution on pipe section installation and construction, and avoid the problem of stacking of inventory pallets, while ensuring the timely delivery of pallets of finished pipe sections.

[0007] In a first aspect, a management method for quantitative disassembly of a ship piping system is provided, comprising the following steps:

[0008] S1. After establishing the piping system model within the ship area, determine the manufacturing cycle and assembly cycle of all pipe sections in the piping system model within the area based on the manufacturing characteristics and installation characteristics of different types of pipe sections.

[0009] S2. Divide all pipe sections in the pipe system model in the area into multiple standard trays through quantitative splitting.

[0010] S3. Determine the production cycle and assembly cycle of each standard pallet based on the production cycle and assembly cycle of each pipe segment.

[0011] S4. Determine the delivery and installation date of each standard pallet based on the production plan. Determine the start date of production of each standard pallet based on the production cycle, assembly cycle, and delivery and installation date of each standard pallet.

[0012] S5. Production is carried out in sequence according to the start date of production of each standard pallet. After the production of each standard pallet is completed, each standard pallet is delivered and assembled according to the scheduled delivery and installation date.

[0013] In one embodiment, before step S1, the manufacturing characteristics and installation characteristics of different types of pipe segments are obtained, including the following:

[0014] Based on factors such as the material and processing technology of the components in the pipe section, a standard production cycle table for each type of pipe section is formulated, and the production time of each type of pipe section is consulted and determined through the standard production cycle table; based on factors such as the diameter of the pipe section, a standard installation cycle table for the pipe section is formulated, and the installation time of each type of pipe section is consulted and determined through the standard installation cycle table.

[0015] In one embodiment, in step S1, determining the manufacturing cycle and assembly cycle of all pipe segments in the pipe system model within the region includes:

[0016] After the large-area piping system modeling is completed, the production type of each pipe segment is clarified, and the production time of the pipe segment is calculated by matching the standard production cycle table of the pipe segment; the installation type of each pipe segment is clarified, and the installation time of the pipe segment is calculated by matching the standard installation cycle table of the pipe segment.

[0017] In one embodiment, in step S2, the quantitative splitting includes primary splitting, secondary splitting, and tertiary splitting.

[0018] In one embodiment, the first-level splitting includes: dividing the large area space where the pipe segment model is located into multiple small area spaces, and determining the small area to which each pipe segment belongs based on the spatial position of each pipe segment, to obtain multiple first-level pipe segment sets based on spatial division.

[0019] In one embodiment, the secondary splitting is a secondary splitting performed on the primary pipe segment set, including:

[0020] The shortest and longest production times of the pipe segments in the first-level pipe segment set are clarified, and the total time period between the shortest and longest production times is divided into multiple time periods. The time period to which each pipe segment belongs is determined based on the production time of each pipe segment in the first-level pipe segment set, and multiple pipe segments belonging to the same time period are set as a second-level pipe segment set.

[0021] In one embodiment, the three-level splitting includes: establishing a standard assembly workload indicator for a team based on the assembly workload of each pipe segment; and performing a three-level splitting on each of the second-level pipe segment sets according to the standard assembly workload indicator for the team to obtain multiple third-level pipe segment sets.

[0022] In one embodiment, during the quantitative splitting of pipe segments, priority is given to grouping pipe segments with similar spatial locations and the same material into the same set.

[0023] In one embodiment, in step S5, the scheduled delivery and installation date is the delivery date of the standard pallet, and multiple standard pallets are delivered to the designated area in batches according to their respective scheduled delivery and installation dates, and the corresponding construction teams complete the installation of the pipe sections in the standard pallets.

[0024] According to a second aspect of the present application, a management system for quantitative disassembly of ship piping systems is also provided, comprising a memory and a processor, wherein the memory stores a computer program, which, when executed by the processor, implements the management method for quantitative disassembly of ship piping systems provided in the first aspect.

[0025] Compared with the prior art, the present invention has the following advantages:

[0026] In the technical solution of the present application, the pipe segment models within the region are quantitatively split based on the manufacturing characteristics of the pipe segments. This ensures that each pipe segment within the pallet has relatively consistent manufacturing characteristics. At the same time, the size of the pallet is quantified based on the workload of pipe segment assembly. While ensuring the timely delivery of pallets of finished pipe segments, the impact of pallet production and distribution on pipe segment installation and construction can be reduced, and the problem of stacking of inventory pallets can be avoided. This not only saves space, but also facilitates installation and construction, avoiding the need for construction workers to search for specific pipe segments from a large number of pipe segments, and thus improving work efficiency.

[0032] According to the first aspect of this application, see Figure 1 First, a management method for quantitative disassembly of ship piping systems is provided, comprising the following steps:

[0033] S1. After establishing the piping system model within the ship area, determine the manufacturing cycle and assembly cycle of all pipe sections in the piping system model within the area based on the manufacturing characteristics and installation characteristics of different types of pipe sections.

[0034] S2. Divide all pipe sections in the pipe system model in the area into multiple standard trays through quantitative splitting.

[0035] S3. Determine the production cycle and assembly cycle of each standard pallet based on the production cycle and assembly cycle of each pipe segment.

[0036] S4. Determine the delivery and installation date of each standard pallet based on the production plan. Determine the start date of production of each standard pallet based on the production cycle, assembly cycle, and delivery and installation date of each standard pallet.

[0037] S5. Production is carried out in sequence according to the start date of production of each standard pallet. After the production of each standard pallet is completed, each standard pallet is delivered and assembled according to the scheduled delivery and installation date.

[0038] Specifically, by the delivery date, all pallets have been manufactured and delivered; according to the established delivery and installation date sequence, the module pallets are delivered to the designated area in batches, and the corresponding construction teams complete the pipe section installation.

[0039] This application uses the manufacturing characteristics of pipe segments as a basis to quantitatively split the pipe segment models within the region. This ensures that each pipe segment within the pallet has relatively consistent manufacturing characteristics. At the same time, the size of the pallet is quantified based on the workload of pipe segment assembly. While ensuring the timely delivery of pallets of finished pipe segments, it can reduce the impact of pallet production and distribution on pipe segment installation and construction, and avoid the problem of stacking of inventory pallets. This not only saves space, but also facilitates installation and construction, avoiding the need for construction workers to search for specific pipe segments from a large number of pipe segments, and thus improving work efficiency.

[0040] In one embodiment, before step S1, the manufacturing characteristics and installation characteristics of different types of pipe segments are obtained, including the following:

[0041] Based on factors such as the material and processing technology of the components in the pipe section, a standard production cycle table for each type of pipe section is developed. The production time of each type of pipe section can be checked and determined through the standard production cycle table. Based on factors such as the diameter of the pipe section, a standard installation cycle table for the pipe section is developed. The installation time of each type of pipe section can be checked and determined through the standard installation cycle table. The specific steps include:

[0042] a. Taking each pipe segment as the research object, identify the key factors that affect the pipe segment production cycle during the production process, from order submission to product delivery, and establish quantitative indicators for each factor to describe the impact on the pipe segment production cycle.

[0048] Table 3 Influence of processing technology on pipe segment production

[0049] Serial number Processing technology Quantitative indicators (days) 1 galvanized 3 2 paint 2 … … …

[0050] b. Using pipe segments as the research object, identify the key factors that affect the installation cycle during the installation process and establish quantitative indicators for each factor to describe its impact on the installation cycle. Here, the maximum diameter of the components within the pipe segment is used as the key influencing factor, as shown in Table 4.

[0051] Table 4 Effect of diameter on pipe installation

[0052] Serial number caliber Quantitative indicators (man-days) 1 DN50 0.08 2 DN200 0.2 … … …

[0053] For example, if a pipe section is made of alloy steel and requires painting, the standard production cycle for the alloy steel pipe is 10 + 2 = 12 days. If the maximum diameter of the internal components of the pipe section is DN200, the standard installation cycle for this pipe section is 0.2 man-days.

[0054] In one embodiment, in step S1, after the large-area piping system model is completed, the production type of each pipe segment is determined, and the production time of the pipe segment is obtained by matching it with the standard production cycle table of the pipe segment; the installation type of each pipe segment is determined, and the installation time of the pipe segment is obtained by matching it with the standard installation cycle table of the pipe segment. Specifically, the following steps are included:

[0055] S11. After the piping system production design is completed, the piping system model is segmented and a pipe segment object is generated;

[0056] S12. According to Table 2, the quantitative indicators A1, A2, ..., Ax of the material of each component in the pipe segment affecting the pipe segment production cycle are obtained in sequence, and Amax (the maximum value among A1, A2, ..., Ax) is calculated;

[0057] S13. According to Table 3, determine the quantitative index B of the pipe segment processing technology affecting the pipe segment production cycle;

[0058] S14, the standard production cycle of the pipe section is obtained as Amax+B, recorded as M;

[0059] S15. Obtain the diameters D1, D2, ..., Dx of the components in the pipe section in sequence, and match the largest diameter to Table 4 to determine the quantitative index C of the diameter's impact on the pipe section installation period.

[0060] S16. Calculate the standard installation period F of the pipe section, where F=C.

[0061] In one embodiment, in step S2, the quantitative splitting includes primary splitting, secondary splitting, and tertiary splitting.

[0062] In one embodiment, the first-level splitting includes: dividing the large spatial region where the pipe segment model is located into multiple small spatial regions, and determining the small region to which each pipe segment belongs based on its spatial position, thereby obtaining a plurality of first-level pipe segment sets based on spatial partitioning. Specifically, the following steps are included:

[0063] S21a. According to the regional construction mode, the large area space of the pipe segment model is divided into multiple small areas to facilitate pallet distribution, pipe segment installation and other tasks. The small areas can be divided according to the hull sections, and the small areas are named z1, z2, ..., zn.

[0064] S22a. Based on the spatial position of the pipe segment model and its positional relationship with each small area space, all pipe segments in the large area space are divided into small area spaces in sequence, obtaining multiple pipe segment sets Z1, Z2, ..., Zn with the same name as the small area spaces, and the intersection of any two sets is an empty set.

[0065] Perform a secondary split on the first-level pipe segment set. Identify the shortest and longest production times for the pipe segments within the first-level pipe segment set, and divide the total time period between the shortest and longest production times into multiple time periods. Determine the time period to which each pipe segment belongs based on the production time of each pipe segment within the first-level pipe segment set, and set multiple pipe segments belonging to the same time period as a second-level pipe segment set. This specifically includes the following steps:

[0066] S21b. Process the set Zi, where i∈(1, 2, 3, ..., n), and obtain the standard production time M1, M2, ..., Mx of each pipe section in the set in turn, and calculate Mmax (the maximum value among M1, M2, ..., Mx) and Mmin (the minimum value among M1, M2, ..., Mx).

[0067] S22b, with 3 days as the separation segment, there are k time periods in total, namely (Mmin, Mmin+3), (Mmin+3, Mmin+6), ..., (Mmin+3*(k-1), Mmax).

[0068] S23b. Based on the standard production time of the pipe segment model, all pipe segments in the set Z1 are divided into corresponding time periods in sequence to obtain multiple pipe segment sets Zi1, Zi2, ..., Zik, and the intersection of any two sets is an empty set.

[0069] S24b, repeat steps S21b to S23b, continue processing the next first-level pipe segment set, until the second-level splitting of all first-level pipe segment sets is completed, and all pipe segments are split into multiple second-level pipe segment sets.

[0070] In one embodiment, the three-level splitting includes: establishing a standard assembly workload indicator for a team based on the assembly workload. Based on the standard assembly workload indicator, the secondary pipe segment set is split into three levels to obtain multiple tertiary pipe segment sets. The assembly workload of each tertiary pipe segment set meets the standard indicator. Specifically, the following steps are included:

[0071] S21c. Based on the specific conditions of on-site construction, determine the standard assembly workload indicator based on the three-day assembly workload of the on-site construction team. This quantitative data is recorded as T, with the unit being person-days. For example, using a standard three-person construction team, the T value is 9.

[0072] S22c. Process the set Zik, where i∈(1, 2, 3, ..., n), k∈(1, 2, 3, ..., ki), obtain the standard installation time of the pipe segments in the set in turn, and sum them up to obtain the overall assembly workload W of all pipe segments in the set.

[0073] S23c. Verify the overall assembly workload W and the team's standard assembly workload T. When W > 1.2*T, the pipe segment set needs to be further split to obtain multiple pipe segment sets, denoted as Zik1, Zik2, ..., Zikj, such that the assembly workload of the split pipe segment sets is less than or equal to 1.2*T.

[0074] S24c: Repeat steps S21c to S23c to process the next secondary pipe segment set until all secondary pipe segment sets are split into three levels, and all pipe segments are split into multiple third-level pipe segment sets. The third-level pipe segment sets are defined as standard pallets.

[0075] It should be noted that in the process of quantitative splitting of pipe segments, priority is given to dividing pipe segments with similar spatial positions and the same material into the same set.

[0076] In one embodiment, in step S4, the delivery date of each standard pallet is obtained in conjunction with the overall production plan, and the delivery, installation, and assembly dates of the pallets can be further determined. The production start date of the standard pallets is then determined based on the calibrated production time of each standard pallet. Specifically, the following steps are included:

[0077] S41. The installation workload for each standard pallet is approximate, so it is recorded as T.

[0078] S42. Based on the overall production plan, the delivery date of each standard pallet's finished product can be determined. Based on the installation dependencies of the pipe sections between pallets, the pallet delivery and installation dates are adjusted based on the pallet delivery date to facilitate installation work by on-site workers.

[0079] S43. For any standard pallet, obtain the standard production time M1, M2, ..., Mx of all pipe segments in the standard pallet in sequence, and define Mmax (the maximum value among M1, M2, ..., Mx) as the production cycle of the standard pallet.

[0080] S44. Determine the production start date for each standard pallet based on the finished product delivery date and production cycle of each standard pallet, so that the pipe section production unit can formulate a pipe section production plan to ensure that all pallets can be delivered on schedule.

[0081] In one embodiment, step S5 specifically includes the following:

[0082] S51. By a certain delivery date, all standard pallets belonging to that delivery date have been delivered and passed inspection.

[0083] S52. On the delivery and installation date of the standard pallets, the corresponding departments deliver the finished pallets to the designated area; and the construction teams in the designated area receive the finished pipe segment pallets.

[0084] S53. The construction team quickly finds the corresponding pipe section in the finished pipe section pallet according to the construction drawings and installs it.

[0085] According to a second aspect of the present application, a management system for quantitative disassembly of ship piping systems is also provided, comprising a memory and a processor, wherein the memory stores a computer program, which, when executed by the processor, implements the management method for quantitative disassembly of ship piping systems provided in the first aspect.

[0086] In summary, this application uses the manufacturing characteristics of pipe segments as a basis to quantitatively split the pipe segment models in the area. This allows each pipe segment in the pallet to have relatively consistent manufacturing characteristics. At the same time, the size of the pallet is quantified based on the workload of pipe segment assembly. On the one hand, the production plans for pallet manufacturing, delivery, and distribution can be arranged in a refined manner to make the production plan more reasonable, ensure the timely delivery of the finished pipe segments on the pallets, and reduce the impact on the installation and construction of the pipe segments. On the other hand, with the help of quantitative pallets, the refined distribution of pipe segments can be achieved, and the stacking of inventory pallets can be reduced. This not only saves space, but also facilitates installation and construction, avoiding the work of construction workers looking for specific pipe segments from a large number of pipe segments, and is conducive to improving work efficiency.

[0087] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
