The shipbuilding industry until the '80s was an industry of scale. The key was to build a shipyard by investing a large amount of capital, and to inject a lot of manpower to create a huge ship structure from an industrial point of view and at a low cost. Today, as in most industries, time and cost savings remain the same as the goal of technology development, but the shipbuilding industry has neglected to develop new technologies and build infrastructure compared to the machinery / manufacturing sector because of its conservatism. .

However, the shipbuilding industry is at an important point where the world is a single market and must have international competitiveness. Therefore, Korea's shipbuilding industry needs to build an infrastructure equipped with new technology instead of the existing system. Securing new sources of growth must first of all reinforce the innovation capacity of existing industries. For this purpose, it is essential to strengthen shipbuilding technology. Informatization should be reconsidered in each shipbuilding industry's value chain, from research and development to design, construction, and marketing.

In particular, in order to build a ship, business design (design phase) starts according to the type of vessel (commercial vessel, special ship, etc.) and size (drainage), etc., which have been ordered (estimated stage), and the ship planning plan (production stage) in the production plan. Will be established.

Once the sales design is established, a detailed design is made, a purchase schedule is established accordingly, and a reference plan is established to link with the purchase schedule.

Once the detailed design and reference plan is established, the production design required for production is established, and the execution plan required for production is established by department and by sector, and the production of the purchased materials is carried out and the production is executed.

In order to establish the production plan as described above, estimates-> design-> production schedule according to the production schedule, cost plan will be established. In other words, the estimating stage (order), design stage (reference plan), and production stage (production schedule, detailed production schedule plan) for building a ship will be established. At this time, necessary cost, material supply, manpower supply, equipment supply, production time, etc. are planned and set.

Referring to Figure 1, the conventional E-BOM function system as a single level structure to procure the product-P, product-R, product, installation raw materials, etc. under the steps of the installation and production drawings.

In particular, the BOM structure created in SAP is a product, function-oriented BOM created in the design, and the components of the production BOM are reprocessed into a production BOM for purchase / production in procurement for the purpose of using a production order in production.

The existing D / O system provides design information for production, procurement, and procurement. The units of design, planning, procurement, and production are different, and there is no common communication medium. In addition, after generating design information by SAP E-BOM function, procurement / production necessary information was generated by a separate program, and the linkage of materials for generating requirements and required dates was also dualized (standard / executed). In addition, the production order was created before the quantity was confirmed, and history management was not possible due to information tracking and complicated logic.

These conventional problems have been subject to many limitations in the simplification, automation and standardization of the chairman logistics process.

We present a unique design logistics system characterized by procurement of materials through the detail order (DO) stage, which serves as an application unit.

At this time, the material is registered as a component of the M-BOM and MRP is generated to generate the required amount, the material required date is managed by the offset of the M-BOM and the summary DB, and the change history is managed by simplifying the material required date generation logic. do.

In addition, the production process is divided into a reference plan (PS) and an execution plan (PP), the reference plan (PS) has a reference plan activity on the network, the reference plan activity is a first action plan activity (GDO1) ) And the second action plan activity (GDO2).

In addition, the execution plan PP includes a production order, the production order includes an operation, and the operation includes a detail order DO having a work order and a standard time.

In addition, the reference planning activity vs. GDO production order is made of 1: N, and the GDO production order of operation is made of 1: 1.
