This work describes a basic process of OMS/MP in guided weapons on board ship. The OMS/MP which provided basic data of ROC & RAM analysis must be prepared by user But data acquisition Quantified by specific operational environment of ship and related preparing instructions which are not established are now insufficient of reliable weapon systems acquisition. The OMS/MP is an important area that become measures of Acceptance Test and doctrine considering future battlespace environment From a development of the OMS/MP template that describe systematically and as quantitative of shipped guided weapons, combat developer oriented product development & reliable weapon system acquisition are ta be accomplished. This research developed OMS/MP preparation templete that presented quantified OMS/MP derivation and RAM target value calculation process which provide optimum weapon systems design concept to research developers

To develop weapon system, Concurrent Spare Parts(CSP) is one of the important somethings in terms of Intergrated Logistics System(ILS). CSP is very important to improve the availability of weapon system, and various research about CSP are performed. However, most of the research does not consider the effects between sub-item's failure and weapon system's multiple function. In other words, if sub-item's failure does not seriously influence weapon system's specific function, the point, not necessarily to replace sub-item, is not considered. Therefore, the method to calculate CSP based on above consideration is written by failure-function matrix in this paper. The study follows the procedure below. First, it's to define the operation and maintenance procedure of weapon system. Second, failure-function matrix is developed. Third, simulation model is desinged by input data. Finally, The quantity of CSP is calculated by simulation and evolution strategy, meta-model. This study suggests new research direction to calculate CSP.

RAM of elements to support weapon systems is conducted at the initial development phase and standard is suggested to accomplish strategy requirement performance from a design spec. Operational availability is a key point of the military's ability to ensure combat readiness and to win the battle. In the weapon system development phase, operational availability is used as a development standard. The military provides ALDT, operation and standby time, which are elements of operational availability. ALDT is a key element of operational availability that must be maintained for combat readiness, as it depends on the aging of a weapon system, maintenance policies and geographical conditions. Operational Availability to be set at the development phase has many differences from the operational availability that is analyzed in the actual operational phase because ALDT is applied as a simple assumption. In the paper, we analyzed ALDT applying the decision tree method through failure data acquired from initial operation. Through this study, we have devised the optimal ALDT setting method to achieve operational availability about operation when the weapons system is unstable.

항공기 정비는 고도의 기술과 많은 노력, 시간을 필요로 한다. 첨단화 되어가는 항공무기체계에 따라 정비작업도 고도화되어 가면서 시간과 작업량이 늘어나게 되고 정비사 부족 문제를 않고 있는 현시점에서는 업무량은 과중되어 질 수 밖에 없다. 하지만 현재 공군에서는 보다 체계적이고 효율적인 정비사들의 업무 할당에 대한 시스템이나 절차가 없었다. 본 연구는 항공기의 비행스케줄에 따른 정비사들의 정비 시간을 균등히 할당함으로써 업무의 효율을 높이고 향후 정비사들의 스케줄 관리를 위한 지침을 제공하는데 그 목적이 있다. 현재 공군에 있는 실질적인 자료를 가지고 실험을 하여 입력 자료에 대한 현실성을 보다 높였으며, 수학적 모델링을 통하여 구축된 스프레드시트 모형을 가지고 인원할당과 근무시간 할당을 위한 최적의 시스템을 palisade사의 evolver를 사용하여 구축하였다.

As the future national defense plan of government focus on advanced weapon system, military maintenance facility becomes more important. However, military maintenance facility has been managed by director's experience and simple mathematical calculation until now. Thus, the optimization for the management of military maintenance facility is suggested by more scientistic and logical methods in this study. The study follows the procedure below. First, simulation is designed according to the analysis of military maintenance facility. Second, independent variable and dependent variable are defined for optimization. Independent Variable includes the number of maintenance machine, transportation machine, worker in the details of military maintenance facility operation, and dependent variable involves total maintenance time affected by independent variable. Third, warmup analysis is performed to get warmup period, based on the simulation model. Fourth, the optimal combination is computed with evolution strategy, meta-heuristic, to enhance military maintenance management. By the optimal combination, the management of military maintenance facility can gain the biggest effect against the limited cost. In the future, the multipurpose study, to analyze the military maintenance facility covering various weapon system equipments, will be performed.

Since AlphaGo's Match in 2016, there has been a growing calls for artificial intelligence applications in various industries, and research related to it has been actively conducted. The same is true in the military field, and since there has been no weapon system with artificial intelligence so far, effort to implement it are posing a challenge. Meanwhile, AlphaGo Zero, which beat AlphaGo, showed that artificial intelligence's self-training data-based approach can lead to better results than the knowledge-based approach by humans. Taking this point into consideration, this paper proposes to apply Reinforcement Learning, which is the basis of AlphaGo Zero, to the Shipboard Combat System or Combat Management System. This is how an artificial intelligence application to the Shipboard Combat System or Combat Management System that allows the optimal tactical assist with a constant win rate to be recommended to the user, that is, the commanding officer and operation personnel. To this end, the definition of the combat performance of the system, the design plan for the Shipboard Combat System, the mapping with the real system, and the training system are presented to smoothly apply the current operations.

This study proposes an OMS/MP preparation methodology using a simulation method instead of a survey method. We applied our methodology to the next generation detection radar, providing reasonable peace- and war-time OMS/MP values. Based on these results, we propose the process to calculate RAM objective values. The previous survey method required to supplement its method since the method used data from a similar weapon system. In addition, the previous method didn't provide enough reliability for the future weapon system. Instead of using the previous survey method, we propose to use war game simulation, which provides a better OMS/MP values. Based on these results, we propose the logical consecutive process that prepares combat and simulation scenarios, peace- and war-time OMS/MP values and RAM objective values.

The flight test operational procedure artifact includes mission planning, execution methods, and safety measures for each step of test progress. As the development of guided missiles has become more advanced and strategic, flight test has become increasingly complex and broadened. Therefore, increased reliability of the flight test operation procedures was required to ensure test safety. Particularly, the design of the flight test operational procedures required verification through M&S to predict and prepare for the uncertainty in a new test. The relevant studies have published the optimal framework development for flight tests and the model-based improvements of flight test processes, but they lacked the specificity to be applied directly to the flight test operational procedures. In addition, the flight test operational procedures, which consist of document bases, have caused problems such as limitations of analysis capabilities, insensitive expressions, and lack of scalability for the behavior and performance analysis of test resources. To improve these problems, this paper proposes how to design operational procedure of guided missile flight test system by applying MBSE(Model-based Systems Engineering). This research has improved reliability by increasing the ability to analyze the behavior and performance of test resources, and increased efficiency with the scalability applicable to multiple flight tests. That can be also used continuously for the guided missile flight tests that will be developed in the future.
