The purpose of this research is to propose a maintenance support system for deciding assembly sequence of the product and appropriate tools that are used to assembly and disassembly of parts in the product when geometric properties of the product. The digital maintenance system (DMS) is developed to generate the maintenance guideline and the initial experiment is conducted especially for an underwater weapon system with cylindrical structure. DMS considers four factors to find the efficient assembly and disassembly procedure automatically: (1) assembly tree, (2) properties of each part, (3) distance from the center of the product, and (4) volume. Based on the factors, DMS simulate the movement of each tool virtually and the properties of tools are investigated to find an appropriate tool for using assembly and disassembly of each part in the product. The proposed approach integrates modeling, simulation, data configuration, and virtual reality to allow a development of preliminary maintenance guidance.

State-of-the-art design S/W and other 3D systems are used for design and development of weapon system. It is possible to detect problems of design through 3D or VR(Virtual Reality) in advance, and then reduce the development cost by finding solutions before prototype production. Therefore, we can increase efficiency for supportability of weapon system. In this study, we first propose a design verification procedure. Then we verify design of weapon system, underwater guided weapon, as a case study. Finally, we suggest alternatives for underwater guided weapon under development with DMS(Digital Maintenance System) and ICIDO from the point of view of ILS(Integrated Logistics Support). Developed S/W, DMS, draws maintenance procedures for components. Commercial S/W, ICIDO, verifies cable maintainability.

To improve the reliability of a weapon system, we perform the activities: setting the target reliability, reliability allocation, and reliability management, etc. Before starting weapon system development, the target reliability of system is set through advanced research and is allocated to its subsystems at the beginning of development. Then we manage the reliability of system and subsystems to meet the target reliability until completion of system development. In this paper, we research representative reliability allocation methods and introduce the suitable reliability allocation method followed by its application to the underwater guided weapon system. The purpose of this research is to review the proposed reliability allocation techniques and find an appropriate method for underwater weapon systems followed by the validation of its application.
