Society is developing fast. Nobody could expect that computer could be used in purpose of trajectory calculation when the ANIAC was developed in the past. However, nowadays technology development brought computerization which substitutes to mankind's working. And personal computer including internet make our society to be IT age. Such age is in revolutionizing now that could be able to bring a new paradigm. We should prepare to such change which scholars predict the end of revolution could be reached at ubiquitous age. This study is purposing firstly for predicting which changes are arisen in the defence sector when social system will become ubiquitous age. That is how change of ubiquitous paradigm could influence to the defence sector and which appearance could be arisen in ubiquitous defence environment. The second purpose of this study is to predict the characteristics of Planing, Programing, Budgeting, Executing, Evaluating, System (PPBEES) of the defence sector.

Cost estimation has posed a significant challenge to estimators, planners, and managers in both government and military. Considerable historical evidence shows that accurate cost estimation has been difficult to achieve across a wide range of projects, including weapon systems. This paper introduces new cost estimating concept, CAIV(Cost As an Independent Variable) and a cost estimating case study using PRICE model, computer aided parametric estimating models(CAPE) for K1 tank cost estimate. CAIV concept is to set realistic but aggressive cost objectives easily in each acquisition program and to achieve cost, schedule, and performance objectives considering various managing risks with a project manager and industry teams. The Price model is one of computer aided cost estimating models and widely used in U.S. defense system analysis as a tool for CAIV. We analyze theories, inputs, outputs of the PRICE model and present a case study for K1 tank to estimate costs in requirement and concept phase, program and budgeting phase, and life cycle phase. Finally we obtain results that the Price model can be used in various phases of PPBEES depending upon available data and time.

The main purpose of this study is to review the current system and to develop a decision support system for evaluating the priorities among those possible alternatives in the army facility enterprise. This paper also provides an information system which can be effectively applied to various criteria and stages in decision making process such as Planning and Programming phases in PPBEES. The model base of decision support systems uses the concepts of the analytic hierarchy process along with the supplementary techniques such as TOPSIS and 0-1 integer programming. Both AHP and TOPSIS are used scoring approaches in the Planning phase and IP is induced at the Programming phase to give GO/NO-GO solution for each project. We use Expert Choice, Excel and LINDO s/w's to implement a prototyped model. The proposed methodology in this paper enables the decision makers to evaluate the priority based on quantitative and qualitative data in a systematic way.

국방기획관리 제도(PPBEES)에서 기획단계(P)의 전력증강소요가 국방 예산을 초과하기 때문에 계획단계(P)나 예산편성 단계(B)에서 예산을 고려한 우선순위 결정이 필요하다. 본 논문의 목적은 한정된 예산범위 내에서 기 결정된 소요의 우선순위 결정에 영향을 주는 요인을 분석하여 도출하는 것이다. 이를 위해 2014년 방위력개선사업 중 신규 착수 및 계약사업 20개를 쌍대비교하여 소요 우선순위 결정 이유를 도출하고, EFA(Exploratory Factor Analysis)를 통해 6개의 대표 요인을 추출하였다. 6개의 요인에 대한 KMO는 0.779로 요인분석하기에 적절하다고 할 수 있고, 총 분산은 79.590%로 받아들이기에 적절하고, Cronbach's Alpha계수도 모두 0.7 이상을 얻었다. 본 논문은 지금까지 연구가 제한적이던 전력 소요 기획에 있어 실제 업무 유관자를 대상으로 실제 무기체계간 비교를 통해 집행 우선순위 영향 요인을 도출했다는 데에 의미가 있다. 이 같은 집행우선순위 영향요인은 전력소요 우선순위를 결정하고자 할 때 AHP 또는 델파이 등의 다양한 의사결정 방법에 활용될 수 있을 것이며 궁극적으로 한정된 재원 내에서 군사전략목표 달성을 위한 합리적 전력소요 판단에 기여할 수 있다.

In light of the recent developments of transitory nature, it is likely that national defense decision-making will be more difficult to make for years to come. In other words, sudden changes in security environment would call into question the basic assumptions on which we have built our national defense planning and increase the number of the uncertain factors in the decision-making process; the subdivision and ramification of national defense management would increase the factors for decision-making and complicate even further the mutual interactions among these factors; the accelerated pace of sophistication and diversification of weapon systems and military technology would increase the risk of failure and system costs geometrically; and the reduced level of acceptance among the people on the sanctification of national defense in proportion to the rapid progress toward a more democratic and industrial society would engender an increased criticism or checking role by the National Assembly or by the mass media. As the changes in national defense environment and conditions create an innumerable number of new tasks, this paper intends to suggest a few core policy measures to improve the quality of national defense decision-making. More specifically, it proposes to 1) eradicate entirely the bureaucratic behavior and tendencies; 2) utilize actively the brain staff for quality assurance of decision-making; 3) and introduce and apply as a whole set, a total system, or an incorporated pack age the PPBEES(Planning-Programming-Budgeting-Executing-Evaluating-System)/LCMM (Life-Cycle Management Model for System Acquision), the OR/SA(Operations Research/Systems Analysis), and DMIS (Defense Management Information System).
