1 is a configuration diagram schematically showing a steel management system according to an embodiment of the present invention.

Referring to FIG. 1, the steel management system 10 includes an input unit 110, a processing unit 200, a retained steel information database 300, and a display unit 400.

The input unit 110 inputs attributes of the ordered steel required for production, and includes a processing condition input module 110 and an ordered steel material information input module 120.

In the present specification, the ordered steel material means a steel material required for the construction of a ship, etc., and the reserved steel material means a steel material that is received in advance and held in stock. In addition, the replacement steel means a steel material that meets the requirements of the ordered steel.

The processing condition input module 110 inputs a condition of the retained steel corresponding to the condition of the ordered steel required for production.

The processing condition input module 110 includes a steel position selection element 111, a material selection element 112, a thickness selection element 113, a scrap rate selection element 114, a classification selection element 115, and a width selection element 116. ) And length selection element 117.

The steel position selection element 111 may select whether or not the position of the used steel and the position of the retaining steel is used. Specifically, it is selected whether or not the position of the shipyard required to place the ordered steel and the location of the shipyard provided with the retained steel.

The material selection element 112 selects a grade of the ordered steel and the retained steel, which selects whether the materials of the ordered steel and the retained steel are the same.

The thickness selection element 113 selects a condition in which the thickness between the cast steel and the retained steel is consistent. In the case of the thickness selection element 113, not only the thickness of the cast steel and the retained steel may be selected to match, but the retained steel may be selected as a condition that can be used within a certain tolerance range of the cast steel.

The scrap rate selection element 114 may select a scrap rate condition which is a loss ratio between the cast steel and the replacement steel.

The class selection element 115 may select one of the conditions in the case of matching the steel class conditions of the same class (class) and the case where other class steels are also available.

The width selection element 116 and the length selection element 117 may select a condition in which the retaining steel matches the width and length conditions of the cast steel.

The retained steel information database 300 includes information such as the position, material, thickness, class, width, and length of the retained steel received and held.

The processing unit 200 receives the processing condition and the ordered steel information from the input unit 100, compares and discriminates it with the retained steel condition of the retained steel information database 300, and searches for a substitute steel.

The processor 200 may calculate a scrap rate, which is a loss ratio between the ordered steel and the substitute steel, through the ordered steel information and the substitute steel information.

The display unit 400 may display a processing result from the processing unit 200. Specifically, the ordering steel information, the replacement steel information and scrap rate can be displayed, and if there is no retaining steel that matches the ordering steel conditions, only such ordering steel can be displayed separately.

Figure 2 is a flow diagram schematically showing a steel management method according to an embodiment of the present invention.

Hereinafter, a steel management method according to the present invention with reference to FIG.

First, the ordered steel material information and processing conditions required for production are input through the input unit 100 (S100).

The input of the processing conditions may include selecting a condition for matching the position of use and the position of the steel, selecting a condition for matching the steel material, selecting a thickness condition for the steel, and a loss ratio between the ordered steel and the replacement steel. Selecting a scrap rate condition, selecting a class condition, selecting a width condition of the steel, it may be made including a step of selecting the length of the steel.

Subsequently, the processing unit 200 and the holding steel information database 300 compare and determine previously stored steel information and ordering steel information (S200), and search for a replacement steel that satisfies the processing condition (S300).

The retrieved alternative steel may be displayed together with the ordered steel, and the ordered steel without the retained steel that satisfies the condition may be separately displayed (S400).

3 and 4 show an example of steel management by the steel management system 10 according to the present invention.

3 shows a result of searching for substitute steel according to processing condition input.

Referring to Fig. 3, the processing condition is configured to select one of "=" and: X "for each condition, for example, in the steel position item," = "means the use position of the cast steel and the stock position of the retained steel. "X" means that the used location and the stock location do not have to match, in which case the condition can be ignored.

In addition, "+1" in the thickness (Thick) condition means a condition that can allow the error up to "1mm".

Looking at the alternative steel search results of Figure 3, if there is a steel material (that is, replacement steel) that meets the processing conditions for each ordered steel material is displayed together with the ordered steel material and retained steel. That is, the steel holdings corresponding to the ordered steels are indicated.

However, when there are no retained steels meeting the processing conditions or when the number of retained steels required is insufficient, corresponding cast steels are marked with a separate mark (for example, a mark using a different color). do.

4 illustrates an example in which only ordered steels and replacement steels meeting the conditions are displayed at a glance. Referring to FIG. 4, the ordered steel and the corresponding replacement steel may be displayed for each item, and analysis information about the replacement result may be separately displayed. That is, the items such as the total number and weight of the ordered steel, the number and weight of the replacement steel, and the scrap weight and ratio may be displayed at a glance.

According to the steel management system and method according to the present invention, not only can the steel replacement error is reduced, but also the cost can be minimized by reducing the scrap rate.

As described above, the present invention has been described with reference to the preferred embodiments, but those skilled in the art can variously modify the present invention without departing from the spirit and scope of the invention as set forth in the claims below. It will be appreciated that it can be changed.
