The present invention relates to a steel stockyard operating system, and more particularly, to a steel stockyard operating system that queries steel stockyard status and supports efficient operation of the steel stockyard.

In general, several ships are built at the same time in a shipyard, and each ship is completed through various types of steel processing, assembly, and mounting processes.

Usually, as few as hundreds of thousands of steel materials are used to build one ship, ship manufacturers have a steel material stockyard that can store and manage steel materials so that they can be put into processing and cutting processes in a timely manner. Taking care of it.

While designing a ship, a ship manufacturer places an order for steel materials according to the characteristics of a ship block, and the steel materials are received accordingly.

When steel materials are received from a steel material producer, a ship manufacturer classifies, stores, and manages steel materials by ship number and block number to be used in the steel material stockyard before being used for ship construction.

In general, the steel material stocking operation method divides the steel material stockyard into zones, assigns a file number to the pile for each zone, and then assigns a line and block number for each pile to determine the steel material stacking location.

Steel materials that have entered the steel material loading dock are unloaded by a trailer, and workers place and manage steel materials in separate files after determining a bay in the stockyard in consideration of various conditions such as the loading status of each bay and daily workload. do.

To this end, the stocked steel materials are all unloaded at a certain loading dock in the stockyard, and the worker marks the steel material information engraved on the side of the stocked steel material on the upper surface of the steel material by hand. Then, after determining which file to place by referring to the marked steel material information, the assigned file number is marked by hand at the lower left corner of the steel material.

Steel material transportation to the assigned pile is performed by a magnetic crane, and the magnetic crane operator moves the steel material to a predetermined location by visually checking the file number assigned to each steel material and the steel material information marked on the upper surface of the steel material.

Steel materials piled up in the stockyard are put into pre-processing equipment to proceed with steel material pre-processing prior to cutting when the cutting schedule for the relevant line or block approaches.

As described above, there was a problem that the conventional steel stockyard operation method, which had to manually check the status of steel stockpiles, was inefficient.

In order to solve this problem, Korean Patent Laid-open Publication No. 10-2010-0115433 tracks the stocking status of steel materials in real time through a monitoring system, and optimizes the movement plan of steel materials accordingly to create an efficient work schedule. ), an optimal steel material stacking algorithm and a lot management method for missing steel materials were proposed considering the production schedule and stacking status that automatically generate the steel material. However, it is unreasonable to computerize all the information about the change plan that is managed from time to time at the site where the amount of steel stock fluctuates greatly depending on the amount of orders received in shipyards and the method of operating stockyards changes frequently according to the amount of steel stock received. Therefore, it is difficult to systematize this and establish an optimal work plan, and it is difficult to automatically create an optimal schedule because the work schedule in the steel stockyard must always be flexible in case there is a change in the production plan.
