우리 해군은 함정 제품모델(Naval Ship Product Model, NSPM)을 중심으로 하는 협업 제품개발 환경 구축을 통해 설계 데이터의 재사용성과 M&S의 활용도를 높이고 있다. 그 결과 설계결과의 신뢰성이 높아지고 있으며, 이를 활용한 운영, 건조 시뮬레이션을 통해 소요군의 요구사항이 면밀히 반영되도록 하는 연구도 진행 중에 있다. 이에 따라 설계 데이터의 DB 구축 및 그 품질에 대한 중요성이 부각되고 있으나, 그와 관련된 연구는 초기상태에 머물러 있는 실정이다. 본 연구에서는 저자들의 선행연구 결과인 함정 제품모델의 품질검증 방법론에 기초하여 함정 제품모델을 구성하고 있는 형상요소의 구체적인 품질검증 방안과 이를 자동화하기 위한 연구를 수행하였다. 함정 제품모델 데이터 중 상대적으로 중요하며, 검증과정에 많은 시간이 소요되고 있는 선각모델을 사례연구 대상으로 정의하였으며, 자동차산업에서 사용되고 있는 제품데이터품질(Product Data Quality, PDQ)을 형상검증 기준으로 활용하였다. 최종적으로 선각모델의 형상 품질검증을 위한 기준과 알고리즘을 제안하였으며 이에 기반 한 초기 시스템을 개발하였다.

지금까지 제조업에서는 CAx(CAD, CAE, CAM) 시스템을 중심으로 설계와 생산의 효율성 증대를 이뤄왔다. 최근에는 제품을 중심으로 PLM(Product Lifecycle Management), 디지털 메뉴팩처링(Digital Manufacturing) 등의 개념을 도임하고 있으며, 이를 기반으로 설계와 생산의 효율성 증대뿐만 아니라, 디지털 제품을 중심으로 하는 제품 개발환경 구축을 통해 제조업의 불변과제 해결과 경쟁력 확보를 위해 노력하고 있다. 본 논문에서는 함정 설계와 정보 관리를 위한 프로세스 및 프레임워크 연구를 수행한다. 그리고 함정획득에 SBA 개념을 적용하기 위한 인프라스트럭쳐에 대해 연구를 수행한다. 객체 지향 개발방법론의 요구사항 분석법에 기반을 둔 SBA(Simulation-Based Acquisition) 프레임워크 정의 방법론을 정립하고 이를 바탕으로 3 차원 함정제품모델 중심의 획득업무 분석을 통해 SBA-NS 아키텍처와 함정제품정보(NSPI : Naval Ship Product Information) 참조모델을 정의하고자 한다.

In automotive industries, reusability of product information is increasing through database construction of previous product data. The product data is stored by data quality management in product information systems. For naval ships, have the functional similarity by the ships of the same classification and class, that are built by series. Information of hull structures as well as embarked equipments are similar. So it would be effective to use database systems that are considered product information quality of previous ships in design and production processes. In this paper we discuss product information quality in database construction of naval ship product models. For this, we propose a basic concept and reference model for data quality verification. Based on this concept, A verification guideline is defined and it is applied for the case study of the digital naval ship which was built to the naval ship product model.

The Korean navy has made many efforts to apply the concepts of PLM (Product Lifecycle Management) and M&S to its naval design and production. However, most of the efforts that have being applied to some acquisition processes, focused only on the element technologies without information models and data frameworks. This study discusses an information model of naval ships for advanced naval acquisitions. We introduce a naval ship product model, and it refers to the DPD (Distributed Product Description) concept of SBA (Simulation-Based Acquisition). To realize the product model concept, we design a data architecture and develop a Product Model Management System (PMMS) based on a PDM System. It is validated through the case study of building the product model of the battle ship that the PMMS has the applicability to effectively manage the naval ship acquisition data on the basis of a 3D product model.

To improve the naval ship acquisition process, systems engineering, modeling and simulation, etc. have been introduced, and there has been ongoing research on acquisition systems for effective support of it. However, due to characteristics of the naval ship acquisition process, development process mainly carried out at a shipyard such as basic design, detailed design, construction and test is difficult to integrate with the acquisition systems of IPT(Integrated Project Team). In addition, research aimed to improve this is rather lacking. In this paper, the naval ship product structure concept proposed in previous research was applied to the basic design system at shipyard, and basic research for expanding the coverage of naval ship acquisition systems to the basic design phase is performed. A data structure of modeling system appropriate to the basic design phase was proposed through research findings and the prototype system based on it was implemented.

Many manufacturers define the system of a new product flexibility, and take advantage of previous-product information using the product configuration concept. Product configuration is an approach that defines the system of a new product centered on the product structure by referring to the previous-product information. In this paper, it is established how to apply the concept of a product configuration utilizing previous-ships information in construction cost estimation process systematically and effectively. For this, we define the advanced-construction cost estimation process based on a naval ship product model, and design construction cost estimating model. It is validated that this process and model have the applicability through the case study of the construction cost estimating of the mine-warfare ship.
