Purpose: The purpose of this study is to identify key performance evaluation items and factors that are effective and practical for project management of defense standard standard improvement projects, and to develop a quantitative performance evaluation model. Methods: For the development of a performance evaluation model for defense standard improvement projects, we analyzed past major project performance and derived evaluation items and factors. To increase the objectivity and efficiency of project evaluation, we developed an evaluation index that enables relative evaluation of evaluation targets, and calculated the main importance of evaluation items using the Analytic Hierarchy Process (AHP) method based on the main opinions of expert groups. Results: The study resulted in the identification of main performance items for defense standard improvement projects, which were classified into defense standard conformity review performance and defense standard improvement performance items. We also simplified the evaluation model by integrating various evaluation items into similar evaluation factors. Additionally, we developed a quantitative evaluation index that enables relative evaluation of the targets and verified the objectivity and validity of the suggested performance evaluation model by reevaluating it using performance data from past commissioned professional institutions Conclusion: Developing a quantitative evaluation model for defense standard improvement projects is expected to provide a means of measuring the effectiveness of the project, and to be used as a tool to determine the appropriateness and effectiveness of medium and long-term project plans.

Most existing studies on the wide-area differential global positioning system (WADGPS) employed a grid ionosphere model for error correction in the ionospheric delay. The present study discusses the application of satellite-based ionospheric delay model that provides an error model as a plane function with regard to individual satellites in order to improve accuracy in the WADGPS. The satellite-based ionospheric delay model was developed by Stanford University in the USA. In the present study, the algorithm in the model is applied to the WADGPS system and experimental results using measurements in the Korean Peninsula are presented. Around 1 m horizontal accuracy was exhibited in the existing planar fit grid model but when the satellite-based model was applied, correction performance within 1 m was verified.

In this paper, we consider a rule of application of PRICE(Parametric Review of Information for Costing and Evaluation) model to the environment of Korean defense industry. The PRICE model which is a computer model to estimate the cost of an acquisition program, was developed for the regulation of defense acquisition program in the United States. Therefore, it is essential for us to figure out how we can adopt it under our defense acquisition regulations. We will give an alternative method to apply the PRICE model to the mapping problem between two regulations.

방위산업은 국가 안보 유지를 위한 기간산업이자 첨단기술이 집약된 미래지향 산업으로써, 방위산업의 연구개발은 무척 중요하다. 우리 정부의 자주국방에 기반을 둔 과감한 정책으로, 국내 방위산업은 양적, 질적으로 많은 성장을 이루었다. 하지만 전문화 및 계열화 제도의 폐지에 따른 경쟁체제의 도입은 국내 방위산업체의 효율성 및 생산성 향상의 필요성이 대두되는 계기가 되었다. 본 연구에서는 DEA와 Super-SBM을 이용하여 국내 방위산업체의 연구개발 효율성을 측정하고자 한다. 이를 위해 한국방위산업진흥회의 '2019 방산업체 경영분석' 데이터를 활용하였으며, 국내 방위산업체의 연구원수 및 투자액을 투입변수로, 매출액을 산출변수로 설정하여 분석을 수행하였다. 방위산업체의 효율성을 분석하기 위해 규모수익불변(CRS)을 가정하는 CCR 모형과 규모수익가변(VRS)을 가정한 BCC 모형을 활용하였으며, 효율적인 업체들 간의 순위를 확인하기 위해 Super-SBM 모형을 사용하여 초효율성을 도출하였으며, 국내 방위산업체는 대체로 비효율적인 모습을 보였다. 본 연구를 통한 국내 방위산업체의 연구개발 효율성을 파악하여 향후 국내 방위산업체의 육성 정책 수립에 도움이 되기를 기대한다.
