Description

Automatic generation of standard GORM structure {STANDARD BOM STRUCTURE AUTO GENERATION METHOD}

The present invention relates to a method for implementing a design plan PRELIMINARY BOM early on the information processing device by using the MASTER BOM in the design of similar ships, copper wire boats or new ships in shipyards.

In the prior shipyard, the MANUAL work was performed according to the following steps (a) to design similar ships, copper ships or new ships (see FIG. 1).

end. PROJECT / OPTION / PE / BLOCK TREE structure MANUAL by BLOCK DIVISION Standard: Before the ship is built, BLOCK DIVISION is distributed to the design department, which divides the ship into blocks that can be produced in units of blocks to make the ship in the production process. By looking at the BLOCK DIVISION of the line, the block structure is combined to become PE, and the PE is combined to make an OPTION structure.

I. Review the use of OPTION: Review whether the OPTION to be configured is the same as the existing OPTION. In this case, existing equipments will be used as they are.

All. ITEM Review of Production ACTIVITY / ROUTING Criteria: The target ITEM for ACTIVITY and ROUTING is reviewed by the design department to see whether it is necessary to create or not enter the appropriate structure. In this case, it is not necessary to create an ITEM means that there is no work in the structure.

la. After the TEMPLATE (EXCEL) is confirmed, the upper structure is composed through TPI: Based on the TEMPLATE (EXCEL) checked in the design department for design creation, the ITEM is created by loading the EXCEL file from the TPI and sending it to PLM. It is serialized and the BOM structure is automatically generated.

hemp. PRELIMINARY BOM CONFIGURATION (PENDING & STANDARD ITEM)

However, there are many problems with the manual work method as follows.

First, there is excessive manual work. In order to create the upper tree structure with reference to the block division, it is necessary to create an ITEM with MANUAL and associate BOM with each other.When forming PRELIMIANRY BOM, the PENDING ITEM & STANDARD ITEM connection must be configured with MANUAL.

Second, errors can occur in the ITEM & BOM structure. Duplicate structures can be created between departments and missing ITEM & BOM structures due to manual work can occur. In addition, there is a high possibility of confusion in post-department departments due to missing ITEM for production ACTIVITY / ROUTING connection.

Third, there may be confusion in procurement, logistics, production, management, and cost sectors due to excessive technological change. PR / PO, production planning, cost and accounting errors can occur due to ITEM changes and BOM structure errors.

Fourth, it is difficult to establish a standard structure. It is difficult to establish a standard structure according to departmental MANUAL management and the efficiency of the system may decrease with increasing MASTER DATA. If the performance of PROJECT BOM is accumulated, BOM information will continue to accumulate by MODEL (group of ships with the same ship type and similar specifications). At this time, such BOM information is collectively called MASTER BOM. When creating PROJECT BOM in the future, if there is similar structure in MASTER BOM, the structure is used. By the way, as the data of the MASTER ship is built, the more the ship is built, the more difficult it is to establish a standard structure, and it is difficult to utilize the OPTION from many MASTERs. Therefore, it is necessary to find a way to make it easier to utilize the data of the MASTER line by establishing a standard structure.

The present invention has been proposed to solve the above problems, it is possible to construct a design plan PRELIMINARY BOM early on the information processing device by using the MASTER BOM in the design of similar ships, copper wires or new ships in shipyards The goal is to provide a way to implement it.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted. In addition, the following will describe a preferred embodiment of the present invention, but the technical idea of the present invention is not limited thereto and may be variously modified and modified by those skilled in the art.

First, terms necessary for describing the present invention will be defined first.

* OPTION: It is a unit that classifies the functions necessary for constructing the product according to purpose and use. The blocks are combined to become PE and the PE is combined to form an OPTION. And the OPTION will come together to make a PROJECT. This is mainly the case of large blocks mounted as goliath cranes at the DOCK site.

* ACTIVITY: The work or group of work performed for the completion of work by each responsibility unit. It is used as a unit of performance aggregation and process control.

* ROUTING: Process standard information for production, which includes work department, process effective date, material release method, resource name, cost charging method, resource usage unit, scheduling method, and other production related information not defined in BOM. In addition to the BOM, it is used as the basic information for work order and material supply and demand planning.

* TEMPLATE (EXCEL): EXCEL file that shows the design items for each OPTION / PE / BLOCK in the table before constructing the BOM for the ship. When the design workers check the necessary design items for the structure, the BOM is in accordance with the structure. You will create a superstructure.

* PENDING ITEM: SPEC / MAKER / Design, etc. is not confirmed, so the final information on PROJECT BOM is not attached and the representative ITEM named PENDING is temporarily attached. The most similar ITEM on the existing line is used as reference ITEM and PENDING ITEM attribute values.

* STANDARD ITEM: ITEM of standardized BOM structure by ship type / building base.

* TPI: Abbreviation for 'TRIBON PLM INTERFACE', a module that enables batch sequencing and batch transfer operations for uploading items modeled (design information design) through PB (CAD program) in PLM to be.

STANDARD STRUCTURE The relationship between the items that make up a line can be plotted as a pyramid. In order to construct the structure, the structure should be centered on the vertex of the pyramid. The STANDARD STRUCTURE is a structure corresponding to the upper end of the pyramid structure. In general, the structure from the line to the unit block structure is configured as a superstructure.

* PLM stands for 'PRODUCT LIFECYCLE MANAGEMENT'. It is a system that manages ENGINEERING DATABASE that occurs in the life cycle of products with a focus on R & D. Correlate and manage all data related to product development, from product planning to design / manufacturing / certification and marketing, including BOM, plan, model, CAD drawings as well as project data, records and documents. All the necessary data for each stage of development, including images, images and more are included.

* ERP: Short for “ENTERPRISE RESOURCE PLANNING”, it refers to an enterprise-wide integrated system that enables rapid and transparent business processing by sharing information in real time through integrated management of overall business processes.

* BOM: means 'BILL OF MATERIAL'. Specifically, it contains structured information about which parts (ITEM) a ship (product) consists of, and the relationship between the parts (ITEM). Means data defined. At this time, the part (ITEM) is a concept that collectively refers to the materials that go into the shipbuilding, such as raw materials, semi-finished products, finished products.

* PROJECT BOM: A BOM corresponding to a specific line, which means a structured structure of material details used to produce products for a specific line by selecting group items and values by characteristics.

* PRELIMINARY BOM: BOM for design / production / management plan prior to drawing confirmation. It is the initial stage of PROJECT BOM. It is a draft for PROJECT BOM composition and is used for scheduling and estimating quantity.

* MASTER BOM: It is the existing performance BOM stored in PLM / ERP. It means the representative BOM for each line type that has been registered so that the selected standard model can be registered and used when constructing the project BOM.

* STANDARD BOM: This is a standard data structure negotiated by each department and managed by classifying common BOM structure by ship type. When constructing PROJECT BOM, BOM is constructed by referring to STANDARD BOM. The STANDARD BOM consists only of the work order unit (JOB ORDER).

* Hull BOM: Refers to BLOCK DIVISION and uses only hull structure (mounted PE, ship PE, BLOCK, etc.)

JOB ORDER: Performance code of the present invention. Process-based information for production, which defines work units, process expiration dates, material release methods, resource names, costing methods, resource usage units, scheduling methods, and other production-related information that are not defined in the BOM. In addition to the BOM, it is used as basic information for work order and material supply and demand planning.

The present invention, as a way to implement a design plan PRELIMINARY BOM early on the information processing device by using a master BOM in the design of similar ships, copper wire boats or new ships in shipyards, see the target of each part 'MASTER BOM Assignment' step of designating line; A 'MASTER BOM extraction' step of extracting DATA having a structure similar to the PROJECT BOM to be currently generated from the MASTER BOM that is permanently additionally structured based on a specific MODEL as the DATA existing in the ERP; 'Generating a design standard structure' to add a design BOM to the hull BOM based on the extracted DATA; A 'PENDING ITEM generation' step of generating a PENDING ITEM including attribute values at the bottom of the design bill of materials consisting of the extracted DATA; Standard 'BOM batch number' step to batch process the PROJECT BOM created through the 'MASTER BOM designation' step to 'PENDING ITEM generation' step, reflect to the PLM and transmit the relevant information to the TPI; A method of automatically generating a BOM structure is presented (see FIG. 2).

'MASTER BOM designation' step is to designate target reference line for each part such as F.BODY, MID DECK, D / H, E / ROOM.

This 'MASTER BOM designation' step consists of four divisions that separate STAGE (large assembly / heavy assembly / small assembly) of block production process into F.BODY, MID DECK, DECK HOUSE & FUNNEL CASING, ENGINE ROOM in PROJECT BOM. 'Separation of input values by STAGE / ZONE' step of adding one division of PE production STAGE and separating it into 5 input values; A 'selection of PROJECT for each zone' step of selecting a reference project in which BLOCK DIVISION is identical among PROJECTs having the same MODEL based on the five input factors; When the JOB ORDER of the reference BOM is created, the ERP JOB ORDER completion BOM extraction step extracts only the complete BOM. Meanwhile, the 'ERP JOB ORDER Complete Criteria Extraction' step is replaced by the 'Extract all MASTER BOM' step, which extracts the entire MASTER BOM when the JOB ORDER of the reference BOM is not generated.

Manual work is required to utilize the existing master, but this step enables efficient master application. Each step will be described below (see FIG. 3).

'Separation of input values by STAGE / ZONE' step: In the present invention, the MASTER BOM is managed by setting five areas having similar characteristics in the vessel. The five parts are divided into four divisions of FLOCK BODY, MID DECK, DECK HOUSE & FUNNEL CASING, ENGINE ROOM, and PE Production STAGE 1 There are a total of five categories.

On the other hand, the BOM in the present invention is composed of a structure similar to the ship drying process. Shipbuilding process proceeds in the order of 'Processing work → Assembly work (Small assembly → Heavy assembly → Contrast) → Preliminary mounting (PE, PRE ERECTION) → Mounting (ERECTION) → Quay wall construction (QUEY). Design / painting work is included. Here, when the installation of the equipment is completed in the contrasting stage, it becomes a block. After doing the JOINT of these blocks early (line PE work), the final PE work is done with a large block (OPTION) just before entering the DOCK. After that, a large block (OPTION) is lifted into the goliath crane at the DOCK site to carry out mounting work (welding).

'Select PROJECT by ZONE' step: Based on the above five input factors, select the reference project with the same block division among the projects with the same MODEL.

'' ERP JOB Extraction of ORDER Completion Criteria 'Step: When the BOM is constructed, it is sent from PLM to ERP SYSTEM. When the relevant line is completed in production, the BOM is processed in JOB ORDER. The code is used based on the completed code.

' MASTER Extract all BOM 'step: This step is implemented in case that some ERP's performance is not processed or ERP system is not established. For example, if the ERP SYSTEM is too late to reflect the results, the system has not yet been properly constructed, or the earnings process is input when work is completed.

'MASTER BOM Extraction' is the data existing in ERP. It is a step of extracting DATA having a structure similar to the project BOM that is to be created from MASTER BOM that is additionally structured based on specific MODEL.

This 'MASTER BOM extraction' step, the 'extract the cosmetics list' to load from the MASTER extraction data to the JOB ORDER lower 1 LEVEL ITEM; A 'Create New Apparel' step of creating a new Apparel ITEM at the same location as the LOADING BOM; It consists of a 'line common structure UPDATE' step that automatically updates the standard structure of equipment (standard structure: data is managed inside the system) that is commonly applied according to a specific stage and zone in a specific project.

According to this step, it is possible to collectively generate the design VIRTUAL CODE early to prevent cross talk between design departments and to efficiently standardize the BOM structure. Each step will be described below (see FIG. 4).

"EQUIPMENT LIST extraction" step: extraction to extract the MASTER BOM to ORDER JOB 1 LEVEL lower structure. This is because the lower 1 level has items linked to and ordered for the work. If there are no items at the bottom, it means no actual installation work. However, if MANHOUR must be put in place, it will be managed in a separate consultation structure.

'New creation of design' step: In the 'process of design list extraction' step, if there is a BOM under the item, the new JOB ORDER CODE is created in the same BOM structure location of the currently working ship. In other words, it is assumed that the line currently being worked on has the same work in the reference line and the corresponding section.

'Structure common structure UPDATE ' step: Create a structure negotiated by MANHOUR and other ship types even if there is no installation work like the 'extract design list' step.

'Generating design standard structure' step is to construct additional design BOM in hull BOM based on extracted data.

This 'creation of the standard structure of the furniture' step, 'determining the presence of the PENDING reference ITEM' judging whether there is an ITEM under JOB ORDER material; A 'PENDING generation' step of generating a PENDING ITEM when the JOB ORDER lower material ITEM exists in the 'determining PENDING reference ITEM' step; A 'select reference ITEM' step of designating the JOB ORDER submaterial ITEM as a reference ITEM; After ERP is finalized, WBS-Activity constant value (Calculation schedule is calculated based on WBS-ACTIVITY value from PROJECT BOM in the Production Planning Department. WBS is called Work breakdown Structure. 'PENDING termination date registration' step of loading and calculating and automatically inputting. On the other hand, the PENDING generation step is replaced by a PENDING non-generation step that does not generate a PENDING ITEM when the JOB ORDER lower material ITEM does not exist in the PENDING reference ITEM determination.

Approximately 4375 MANHOUR is consumed per year to produce the PENDING ITEM, which can be reduced innovatively by this step. Each step will be described below (see FIG. 5).

'PENDING See ITEM determine whether or not "phase: PENDING See ITEM sets connected temporarily to the calculation plan / orders until they are linked to the actual item jeonghaejyeoseo JOB ORDER children. Therefore, if there is an item under the JOB ORDER performance code to refer to, a PENDING reference ITEM is created with that code as a reference value. PENDING ITEM's main input values are reference line, reference item CODE, PENDING ITEM deletion and actual CODE linkage date.

' PENDING generation' step: As in the 'extract design list' step, if there is an item in the lower level of JOB ORDER, the PENDING ITEM is linked to the ITEM as a reference ITEM.

' Select reference ITEM ' step: Enter the item of JOB ORDER sub 1 LEVEL as reference ITEM.

' PENDING Termination Date Registration' Step: After sending to ERP, the termination date is automatically registered according to the planned JOB ORDER schedule. This is to make time management easier when the worker connects the actual ITEM in the future.

'No PENDING ' step: If there is no item in JOB ORDER 1 level LEVEL, PENDING ITEM is not created. Since there is no quantity, it is excluded from the reference.

In the 'Generating Pending ITEM' step, create a Pending ITEM with attribute values under the design BOM that consists of extracted data.

In the 'BOM batch collection' step, the PROJECT BOM generated through the process of 'MASTER BOM designation' to 'PENDING ITEM generation' is collected and reflected in the PLM and transmitted to the TPI.

When BOM of the target ship is completed from PROJECT to PENDING ITEM, ITEM creation work is carried out at the end. In PLM, each ITEM can be created, but the entire ITEM information and BOM connection information can be input at once, so that the BOM can be simultaneously numbered. According to this step, the time can be shortened by generating the BOM collectively.

The above description is merely illustrative of the technical idea of the present invention, and various modifications, changes, and substitutions may be made by those skilled in the art without departing from the essential characteristics of the present invention. will be. Accordingly, the embodiments disclosed in the present invention and the accompanying drawings are not intended to limit the technical spirit of the present invention but to describe the present invention, and the scope of the technical idea of the present invention is not limited by the embodiments and the accompanying drawings. .
