  • This paper presents a strike velocity estimation using the recursive Bayesian filter that operates both correction and prediction models to probabilistically remove noises of sensors and accurately estimate the strike velocity during the real-time experiments. Four different types of bullets such as 5.56 mm M193, 7.62 mm M80, 5.45 mm 7N10 and 7.62 mm MSC were used to validate the proposed method. Compared to the existing method, the proposed method statistically results in higher stability of the strike velocity estimation as well as its reliability for the ballistic limit velocity computation.

  • The purpose of this paper is to present reliability analysis procedures for repairable systems and apply the procedures for assessing the reliabilities of two subsystems of a specific group of military equipment based on field failure data. The mean cumulative function, M(t), the average repair rate, ARR(t), and analytic test methods are used to determine whether a failure process follows a renewal or non-renewal process. For subsystem A, the failure process turns out to follow a homogeneous Poisson process, and subsequently, its mean time between failures, availability, and the necessary number of spares are estimated. For subsystem B, the corresponding M(t) plot shows an increasing trend, indicating that its failure process follows a non-renewal process. Therefore, its M(t) is modeled as a power function of t, and a preventive maintenance policy is proposed based on the annual mean repair cost.

  • This paper deals with the improvement of doctrine, organization, and training for Weapon systems during the defense acquisition process. We analyze the combat development element such as doctrine, organization, and training which is working in the United States of America. then we apply the ideas to our proposal for the improvement of doctrine, organization, and training for weapon systems. This paper will be contributed to the improvement of doctrine, organization, and training and the efficiency of defense acquisition program management.

  • ACTDs exploit mature technologies to solve important military problems. A reducing budget, significant changes in threats, and an accelerated pace of technology development have challenged our ability to adequately respond to rapidly evolving military needs. This work describes ACTD management and its program applications. It is presented a prospective and applications of domestic defense acquisition programs.

  • In digital warfare, communications between combat vehicles should be managed and synchronized in order to ensure the survivability of vehicles. Embedded battle management systems is designed to share battle information with combat vehicles in real-time. In this study, the details of embedded battle management systems which are successfully implemented in combat vehicles are presented.

  • In recent years, interest in the welfare of soldiers is increasing. More specifically, soldiers enlisted to fulfill their military service obligations live a group life that is controlled by group life, unlike military officers selected by their will. Therefore, this study aims to verify whether there is an effect of improving the morale of soldiers by increasing the satisfaction of military service meals along with the trend of increasing morale through enhancement of soldier welfare. In order to achieve the purpose of this study, we surveyed 145 army soldiers working in the front and rear areas and used 137 valid samples for analysis. The results of this study are as follows. First, both SERVQUAL (Responsiveness·Assurance, Tangibles) and Servicescape (Spatial Environment, Spatial Design) had a positive (+) effect on military meal satisfaction. Second, military service satisfaction and emotional commitment have a positive (+) effect on morale. Third, satisfaction with military meals has a positive effect on emotional commitment. This research has also shown that improvements in SERVQUAL (Responsiveness·Assurance, Tangibles) and Servicescape (Spatial Environment, Spatial Design) improve military service satisfaction and emotional engagement. Military food service SERVQUAL (Responsiveness·Assurance, Tangibles) and Servicescape (Spatial Environment, Space Design) must pay attention to increase military morale.

  • In this paper, we first present an in-depth survey of the research on Verification, Validation and Accreditation (VV&A) applied in various areas. Then we introduce the characteristics of the military and defense Modeling and Simulation (M&S) and propose the direction of method for VV&A with the identified characteristics. The M&S has been widely used in many different applications in the military and defense area including training, analysis, and acquisition. Methods and processes of VV&A have been proposed by researchers and M&S practitioners to guarantee the correctness of the M&S. The idea of applying the formal credibility assessment in VV&A is originated from the Software Engineering Reliability Test and Systems Engineering Development Process. However, the current VV&A techniques and processes proposed in the research community have not utilized the military-and-defense specific characteristics. We identify the characteristics and issues that can be found in the military and defense M&S. Then propose the direction of techniques and methods for VV&A considering the characteristics and issues. Also, possible research direction on the development of VV&A is proposed.

  • The improvement of the reliability of weapon systems and the reduction of the total life-cycle cost based on the improving of the DT&E system for Company Organized weapon systems research and development are urgently required. The major advanced countries operate test and evaluation centers for military (U.S.), manage a large scale organization of IPT personnel (England) or conduct management of DT&E through a third party organization (France). Based on a survey of experts, an improvement of the DT&E policy in terms of reliability and objectiveness is needed, and management through a third party national defense agency and civilian agency such as the Surion development case is required. In addition, although it appears that efficiency improves when management of DT&E is performed by national defence agencies rather than civilian agencies, it is necessary to proceed by selecting a civilian agency based on competition in the case that it is difficult to select a national defence agency.
