In this paper, with the limited range of ammunition supply point(ASP) at ammunition battalion in specific corps and light automobile battalion(LAB) directly supports its vehicle for ammunition supply, we propose optimal model to minimize transportation time and logistics cost using integer programming(IP) for efficient ammunition resupply allocation during a given operation period of front combat unit. And then, we consider ammunition treatment and supply capacity of ammunition supply point(ASP), constraint elements of transportation ability considering time and cost, ammunition storage capacity of combat unit, combat situation and unit mission to propose this model. Finally, through numerical example, we examine the applicable feasibility of proposed model.

BBU for 155mm projectile has been verified its stable performance and quality reliability through the production for several years. We have researched substitution test for flight test of BBU. Through this research, we expect the verification of quality stability and other collateral effect like the cost reduction and delivery on time.

Bullet impact tests for two solid rocket motors were performed and its results were compared and analyzed. One was loaded with the existing propellant with decreased weight content of burning rate catalyst and added high density additives to improve mechanical properties and the other was loaded with the existing propellant with decreased weight content of burning rate catalyst to improve its insensitivity as well as to maintain the ballistic performance. The composite cases were used for both motors.

This paper presents a fault diagnosis(detection and isolation) approach for the Ammunition Transport Automation system(ATAS). Due to limited time and information available during its cyclic operation, the on-line fault detection algorithm consists of sequential test logics referring to the normal states, which can be considered as a kind of expert system. If a failure were detected, the off-line isolation algorithm finds the fault location through trained ART2 neural network. By the results of simulations and some on-line field test, it has been shown that the presented approach is effective enough and applicable to related automation systems.

The most portion of the Korean Army's ammunition management system has achieved efficiency and automation based on the Ammunition Information System (AIS). However, a few limitations for the automation system constructed at each site, exist in verifying the real time situation. At the present state of technology, the asset visibility of the located ammunitions is basically achieved. On the other hand, the ammunitions in the middle of transportation are difficult to achieve asset visibility. The RFID(Radio Frequency Identification) technology could be an appropriate solution in these circumstances. Therefore, the objective of this paper is to apply the RFID to improve defense asset management, total asset visibility and ammunition distribution efficiency in the ammunition management system of the Korean Army.

In order to enhance sustainable war fighting capabilities, it is important to maintain a good ammunition support system. In this paper, we evaluate the performance of ammunition companies using Imprecise Data Envelopment Analysis (IDEA)-BCC and IDEA-Additive model, which can deal with imprecise data in DEA. The input variables of IDEA models were selected by stepwise multiple regression analysis. With the regression model, we could choose the number of soldiers, officers, and ammunition warehouses as input variables that have significant effects on the output performance. Then, we applied the IDEA-BCC model with the concept of potential efficiency. The results of the model indicate that 8 out of 16 ammunition companies are efficient, 7 are inefficient, and 1 is potentially efficient. We could also identify the possible input excesses and output shortfalls to reach the efficient frontier using the IDEA-Additive model.

군사력은 국가경쟁력을 대표할 수 있는 가장 중요한 요소 중 하나이다. 세계 각국에서는 군사력 증진을 위한 군사장비의 수출과 수입이 활발하게 이루어지고 있다. 우리나라의 방산수출은 2006년 2.5억불에서 2017년 약 12배 증가한 31.2억불로 2011년부터 6년 연속 20억불 이상 성과를 달성하였으며 방위산업 수출은 탄약 부품류 위주의 수출에서 첨단 기술력에 기반을 둔 고부가가치 무기체계로 수출품목이 다양화 되고 있다. 이렇듯 우리나라도 이제 방위산업 기술보호에 대한 관심과 노력이 반드시 필요한 시기가 도래하였다. 본 연구에서는 수출 시 또는 적의 피탈에 의해 무기체계가 노출되는 상황에서 핵심기술의 유출을 방지하기 위한 기술보호기법에 대해 조사하고 실제 무기체계에 적용하여 구현하였다.

In order for a gun-launched guided projectile to glide to the maximum range, when to deploy the fin and start flight with guidance and control should be considered in range optimization process. This study suggests a solution to the optimal guidance problem for flight range maximization of the flight model of a guided projectile in vertical plane considering the aerodynamic properties. After converting the nonlinear Multi-Phase Optimal Control Problem to Two-Point Boundary Value Problem, the optimized guidance command and the best fin deployment timing are calculated by the proposed numerical method. The optimization results of the multiple flight rounds with various initial velocity and launch angle indicate that determining specific launch condition incorporated with the guidance scheme is of importance in terms of mechanical energy consumption.

Safety standards for long-range artillery ammunition test and training sites follow the US artillery shooting range safety zone standards. Although the South Korean geographical conditions of shooting ranges are different from those of the United States, there is no safety standard reflecting the South Korean topographical characteristics. Probable error associated with the shooting range, trajectory should be considered in establishing the safety standards. In this study, we present the safety standards for the ammunition testing site suitable for the Korean situation, with applying a concept of trajectory and probable error differed by ammunition type, which are currently confirmed by the South Korean Army's artillery shooting.
