The present invention relates to a simulation system technology specific to the production of ships and offshore plants, whereby the building process and method verification of ships and offshore plants, optimization and verification of facilities and layout, and optimization of production management can be simulated.
High-efficiency production technology has emerged as one strategy for achieving a technological competitive advantage in the shipbuilding and marine industry, and currently, shipyards are making efforts to develop and apply new production technologies and new building methods. As an example of a new technology, a simulation technology to support verification of new methods and optimized production flow is receiving much attention. However, due to specificity of the shipbuilding and marine industry, which is an engineering-to-order industry, there is a limit to directly applying simulation systems and tools for make-to-stock, order industry, such as machinery, automotive, and aerospace, to the shipbuilding and marine industry, so a production simulation technology specialized in shipyard is required.
To meet this need, a study is underway to develop a simulation system for production for ships and offshore plants, which combines IT simulation technology with a traditional shipyard. This study is referred to as a simulation of production for ships and offshore plants framework that systematically integrates sporadically developed production simulation programs. The purpose of this study is to design and develop a module with high recyclability considering scalability. In order to develop an integrated solution by designing the simulation framework for production of ships and offshore plants, it is firstly required to positively reflect on-site requirements in the shipbuilding and marine industry and solve them technically.
At this level, a large number of production simulation programs have been developed in existing large shipyards. These programs are usually developed by the needs and necessity of demand departments and are helping to improve productivity. However, conventional simulations for production of ships and offshore plants are being developed individually and locally by demand departments, and as such they are being developed/operated with different structures. Due to individual developments and different structures, the conventional simulations have drawbacks in terms of module recyclability and reusability.
The foregoing is intended merely to aid in the understanding of the background of the present invention, and is not intended to mean that the present invention falls within the purview of the related art that is already known to those skilled in the art.
Accordingly, the present invention has been made keeping in mind the above problems occurring in the related art, and the present invention is intended to propose an integrated solution for simulation-based production of ships and offshore plants, the integrated solution configured such that a simulation framework for production of ships and offshore plants can be universally applied regardless of different shipyard environments and is separably combined to a planning validation simulation system, a crane block lifting and erection simulation system, a GIS-based dock and quay simulation system, and a block monitoring and logistics simulation system, all of which are utilized in a integrated solution based on the simulation framework for production of ships and offshore plants but are applied differently according to different environments of each shipyard, whereby the integrated solution has scalability and recyclability to be effectively applied to the unique situations of individual shipyards.
