Description

Design BOM management method for smart factory implementation {METHOD OF MANAGING BILL OF MATERIAL ON HULL STRUCTURE IN SHIP DESIGN FOR IMPLEMENTING SMART FACTORY}

The present invention relates to a smart factory, and more specifically, to implement a smart factory that makes arbitrary modification impossible when creating a linear BOM and ensures data consistency of the linear BOM through the linear BOM's own check logic or SAP check logic. This is about the design BOM management method for design.

Typically, in the ship structural production design process, the hull BOM (Bill of Materials) is managed in the form of a editable text file, which sometimes causes inconsistencies between SAP-based hull BOMs.

For example, as shown in FIG. 1, the conventional method for managing the generation and transmission of a line BOM roughly includes a modeling step (S10), a HIBS DB storage step (S20), a tree creation step (S30), It consists of a BOM Diff check step (S40) and a line BOM registration step (S50).

In the modeling step (S10), modeling is performed using structural detailed information (S10), and information about the hull member is extracted.

In the HIBS DB storage step (S20), hull parts information is stored in PLDB (PLate DB), PRDB (PRfile DB), and HIBS DB.

In the tree creation step (S30), analysis drawings are created using tree data, a hull parts list is created, block weight tons (block W/T) are created, robot information is created, assembly series are separated, and DAP is created. Create a (Detailed Assembly Procedure) and create an assembly BOM and a processing BOM.

In the BOM Diff check step (S40), the diff of the assembled BOM and the cut BOM are checked and the results are provided as a Diff file.

In the hull BOM registration step (S50), the previously checked hull BOM is transferred to SAP (company production application program) and registered.

That is, conventionally, when creating a hull BOM, it is created as a text file and can be modified arbitrarily. Even if the hull BOM is inconsistent, it is sent to SAP. In the case of series ships, the text file of the hull BOM can be copied and edited and used, and the BOM There is a problem that inconsistencies occur during revision processing.

Korean Patent Publication No. 1317351 (Method and system for creating corner plate development drawings of ships. 2013. 10. 04) Korean Patent Publication No. 1871300 (Method for automatically generating cut drawings of section steel and automatically extracting materials when designing ships. 2018. 06. 20)

The technical problem to be achieved by the idea of the present invention is to make it impossible to arbitrarily modify the text file related to the hull BOM, synchronize the hull BOM, efficiently perform revision management, and manage the hull BOM for each vessel. The purpose is to provide a design advance BOM management method for smart factory implementation.

In order to achieve the above-mentioned object, the present invention establishes and stores a design schedule according to a standard plan for ship construction, reflects and stores various prior information in modeling, and inputs production technology data into a design integrated database. ; Extracting design information and member information from the integrated design DB, generating a hull BOM for each ship, and storing it in HIBS DB; Confirming data consistency by performing a BOM Diff check of the hull BOM; And according to the information transmitted from the design integration DB, generating design data and 3D model information, and transmitting the hull BOM with confirmed data matching to the design information transmission DB; Design for smart factory implementation, including Provides a hull BOM management method.

Here, a step of identifying a revision may be further included by comparing the initial hull BOM stored in the integrated design DB with the hull BOM requested for revision due to mismatch information.

In addition, it is possible to manage the revision number of the hull BOM and manage revision history information based on the design information transmission DB.

In addition, the step of comparing the assembled BOM of the hull BOM and the cut BOM to perform a BOM Diff check of member quantity, member weight, bending code, and assembled transport line and providing check information may be further included.

In addition, the hull BOM whose data consistency is confirmed may be simultaneously transmitted to the design information transmission DB, and the hull BOM whose data consistency is not confirmed may not be transmitted to the design information transmission DB.

Additionally, data matching of the linear BOM may be performed by the linear BOM's own check logic or SAP check logic.

In addition, the line BOM stored in the HIBS DB cannot be arbitrarily modified and may not be stored or transmitted by copying.

In addition, when generating a hull BOM for each line, error information on the generated assembled BOM and cut BOM can be provided.

According to the present invention, arbitrary modification is impossible when creating a hull BOM, and there is an effect of securing data consistency of the hull BOM through the hull BOM's own check logic or SAP check logic.

In addition, if there is a mismatch after checking the hull BOM diff, transmission is impossible, which has the effect of implementing zero mismatch in the hull BOM.

Furthermore, when working on a series line, a hull BOM is created for each line, making copying of the mother ship hull BOM impossible, and transmitting each hull BOM at the same time to prevent omission of the assembly BOM and automate revision identification. there is.

Hereinafter, embodiments of the present invention having the above-described features will be described in more detail with reference to the attached drawings.

This is an example of an interface screen.

The design line BOM management method for smart factory implementation according to the present invention includes a design integration DB input step (S110), a HIBS DB storage step (S120), a data matching confirmation step (S130), and a design information transmission DB transmission step. Including (S140), the aim is to disable arbitrary modifications when creating the hull BOM, secure the data consistency of the hull BOM through the hull BOM's own check logic or SAP check logic, and implement zero inconsistency in the hull BOM.

First, through the standard plan establishment step (S101), a block (LOT) is created and a block-by-block standard plan including design schedule, production schedule (or production plan), and production shop is established for each block. .

Next, in the design integration DB input step (S110), for ship construction, a design schedule is established and stored according to the standard plan, various prior information is reflected in modeling and stored, and production technology data is input into the design integration DB. .

Here, the modeling is stored in Tribon, a 3D modeling software dedicated to shipbuilding, or in the structural member model storage DB (DB for the entire structure that stores member modeling), which is a data database of AM, and the production technology data is divided into blocks ( Block Division, MainPlate processing instructions, scaffolding arrangement, TEMP.ACC.HOLE, welding shrinkage or LIFT'G PLAN (lifting plan) data may be included.

For example, the design integrated DB is a production technology DB that manages production technology data by block, including block division, welding shrinkage, abacus processing tips, lifting plan, TEMP.ACC.HOLE, and scaffold placement hole, and production information. Production information feedback DB manages feedback data by block, structural modeling is performed without block distinction from structural detailed design information, design modeling information is added from design design information, production technology information is input from production technology DB, and production information is provided. It can be composed of a modeling DB that receives production information feedback data from the feedback DB and reflects it in modeling.

Next, in the HIBS DB storage step (S120), design information and member information are extracted from the design integrated DB, and the assembly BOM (ASS'Y BOM) and cut BOM (CUTT'), which are hull BOM (Bill of Material; member list), are extracted for each ship. G BOM) is created and stored in HIBS (Hull Information data Bank System) DB.

For example, design information and member information include material, thickness, weight, area, shape, bending, welding angle and joint length, margin, excess, distribution increase, and pin jig. It may consist of curved modeling information including (PIN JIG) and template.

Here, when generating the assembled BOM of the hull BOM and the cut BOM for each line, error information of the generated assembled BOM and cut BOM can be provided through an error list.

Next, in the data consistency confirmation step (S130), data consistency is confirmed by performing a BOM Diff check of the hull BOM.

That is, by comparing the assembled BOM of the hull BOM and the cut BOM, member quantity, member weight, bending code, and BOM Diff check of the assembled transmission line can be performed and check information can be provided (S131).

Next, in the design information transmission DB transmission step (S140), design data and 3D model information are generated according to the information transmitted from the design integration DB, and the hull BOM for which data matching was previously confirmed is transmitted to the design information transmission DB.

Here, the design information transmission DB may be composed of a DB of SAP (company production application program), and as shown in Figure 4, BOM Diff check between hull BOMs is sequentially performed (S141) and stored in HIBS DB. (S142), and can be transmitted to SAP by user confirmation (S143).

Meanwhile, as shown in Figure 5, the assembled BOM and cut BOM, which are line BOMs with confirmed data matching, are simultaneously transmitted to the design information transmission DB, and the assembled BOM and cut BOM, which are line BOMs with unconfirmed data matching, are sent to the design information. It may not be transmitted to the transmission DB.

Additionally, data matching of the hull BOM can be performed by the hull BOM's own check logic or SAP check logic.

Here, the simultaneous transmission of the assembled BOM and the cut BOM should be understood as being linked and transmitted at the same time, rather than an exact temporal coincidence, to prevent omission of the assembled BOM.

Meanwhile, as shown in FIG. 3, a step (S150) of identifying a revision may be further included by comparing the initial hull BOM stored in the design integration DB with the hull BOM requested for revision due to mismatch information.

For example, the revision identification step (S150) may be comprised of a mismatched line BOM correction step (S151), a line BOM mutual comparison step (S152), and an identification step (S153).

In addition, it is possible to manage the revision number of the hull BOM and manage revision history information (history data) based on the design information transmission DB.

In addition, the line BOM stored in HIBS DB cannot be arbitrarily modified and may not be saved or transmitted by copying.

Therefore, by configuring the design linear BOM management method for smart factory implementation as described above, arbitrary modification is impossible when creating a linear BOM, and data consistency of the linear BOM is secured by the linear BOM's own check logic or SAP check logic. You can implement hull BOM mismatch zero by checking the hull BOM diff and disabling transmission if there is a mismatch. When working on a series ship, a hull BOM is created for each ship, and copying of the mother ship hull BOM is disabled. By transmitting the line BOM at the same time, omission of the assembly BOM can be prevented and revision identification can be automated.
