R'||'&'||'D project management is a process of decisions concerned with the achievement of goals of objectives. Especially, defense R'||'&'||'D project planning is the key in the successfull management of defense development. The defense project managers are constantly having to perform "what if\ulcorner" exercise, such as what if the project is extended out for an additional cost\ulcorner In this reserch, we developed a schedule-cost analysis model based upon Critical Path Method(CPM) and Venture Evaluation and Review Technique(VERT) for schedule-cost trade off analysis defense R'||'&'||'D projects. In the first step, a deterministic model is developed as a heuristic which deterministic model is developed as a heuristic which determines the schedule extension and reduction cost as a function desired schedule. In the second step, a stochastic network simulation model is developed to analyse the project risk (sucess and failure). The expected time and cost can be determined for desired schedule under the assumptions of stochastic arc data (time and cost) with a various precedence relationships. This model provides the defense R'||'&'||'D managers with an estimated and expected cost for curtailing or extending a project a given amount of time. The effectiveness and efficiency of the proposed methods, a heuristic and stochastic networks simulations, have been demonstrated through examples.

Military aircraft R&D projects require large-scale investment in cost and time, and involve a complex coordination process in decision-making. The R&D project manager should determine the development management priorities as accurately as possible and focus on R&D capabilities, thereby reducing the risks of the aircraft R&D project. To this end, this study aims to reduce R&D risk by prioritizing cost, schedule, and performance, which are basic management factors used in R&D project management in defense project management regulations. Analytic Hierarchy Process (AHP) is applied using a questionnaire for managers in charge of aviation R&D under the Defense Acquisition Program Administration. As a primary result, the importance of the factors that the aircraft R&D project manager should consider was derived in the order of performance, cost, and schedule, and the priorities of performance and cost in the lower layer were also identified. In addition, in order to provide practical risk management measures to aircraft R&D project managers, the results of analyzing 28 cases of US National Transportation Safety Board accidents were compared and analyzed with the AHP analysis results, and management measures suitable for the situation were specified.

Application of system engineering should be realized on necessary condition being to propel National Defense R&D Program. But, these necessity is yet not realized easily to many project managers of Defense Acquisition Program Administration(DAPA). As one person of DAPA project manager, system engineering hard to approaches easily by the word itself. There are a lot of difficult sections where should apply how. This paper established DAPA Project Manager and Acquisition Point of Contact of demand Military by main customer (reader), and wished to make understood more easily and approach system engineering application to these. Also, this paper studied project management example that scientific project management techniques of Earned Value Management(EVM) and Cost As an Independent Variable(CAIV) etc. is taken abuzz in DAPA inside by Project management technique that become reform, arc Integrated in system engineering.

In acquiring and transferring a superior knowledge assesing the intermediate result value of a competitive R&D project is very important for a firm engaging in R&D. Most existing literatures on R&D evaluation are concerned with project selection and resource allocation. In this paper the stage of an R&D project is classified into research, exploratory development, and development. And a model is suggested which evaluates the intermediate result value before completion of development stage under duopoly and oligopolistic competition. Assessed value of the intermediate result transferred to the next tier company can be used as a minimum acceptable price to the inventor when more advanced knowledge acquired through R&D is transferred to the next tier one. The model suggested is composed of structural variables including research cost, success rates, potential profits, discount rate degree of competition. By using exponential distribution for invertion process time in each stage, we derive a formula that can assess the value of the intermediate result, and we demonstrate how the model can be applied to a competitive R&D situation through an example.

During the 'Cold War', DoD had focused on the high performance and timely acquisition which enabled quick field out the superior weapons than the enemy regardless of acquisition cost. But, after the cold war, the focus has been changed to the 'cost effective acquisition' of weapon systems because of tremendous investment cost & economic theory. The U.S. DoD has been tried to make 'the most effective acquisition system'(AR, Acquisition Reform) from mid-80's with their enough experienced program data, and as a result, they had launched the new acquisition procedure - DoD 5000 series - in 1996. DoD is continuously doing the study and making several improvements on the procedure after it had been once announced. On Oct 30. 2002, DoD noticed that they cancelled the DoD 5000 series documents(5000.1, 5000.2, 5000.2-R) and 5000.2-R will be reissued as a guide. The most recent version which focused on 1) evolutionary acquisition and spiral development, 2) procedure for future technology systems including software and IT, 3) supplement on the area of efficiency, flexibility, creativity and innovation of old system was issued by May 12. 2003. This article suggests a 'good idea' based on the reviewing of these DoD efforts for our defense acquisition regulation and procedure to go. It includes the CAIV concept application, IPT utilization, T&E method, cost or price based contract etc-all for the effective acquisition.

The Core in Weapon system R&D is to realize the user required capabilities in limited schedule and cost. Therefore, the design of weapon system focuses to functional design for realization of requirement capabilities. However, the weapon system should not only basically bring the confidence to friendly forces bring fear to enemy forces to maximize the operational effectiveness of weapon systems and we consider the exterior design as the important factor to compete with foreign systems in international defense market besides capabilities and cost. For that reason, we made study case about the visual design decision process applied to the LVT(light tactical vehicle) project which was recent successful deployment among the many R&D projects of auto industry. Based on this case, this study suggests the necessity of the exterior design decision process the maneuver weapon system is developed.

EVMS(Earned Value Management System)는 사업을 관리하는 정부나 사업을 수행하는 업체의 관리자들이 비용과 일정을 주기적으로 추적함으로써 현재의 사업진행 상태를 파악하고 미래를 예측할 수 있는 관리기법이다. 이 관리기법은 미국, 호주 등에서 국방연구개발 사업에 의무적으로 적용해오고 있으며, 그 효율성이 이미 입증된 기법이다. 그러나 외국에서 수행하고 있는 EVMS를 그대로 우리나라에 도입하는 것은 환경적 차이로 인해 많은 문제점을 가지고 있기 때문에 우리나라에 환경에 적합한 EVMS 적용을 위해 연구를 꾸준히 수행하고 있다. 본 논문에서는 먼저 EVMS에 대한 개념을 먼저 고찰 해보고, 저자가 직접 관리하고 있는 차기경구난차량 연구개발사업에 적용한 EVMS 적용실태 분석을 통해 문제점을 도출하고자 한다.

In the Core Technology R&D of the defence area, the development of the related core element technology could be the foundation to develop advanced weapon system in the future. But it might make various problems if you can not accurately define the TRL of the element technology. In other words, if the technology is not sufficiently mature and then the project starts, it might require an increase in the development period and additional cost. Finally the system will be in an incomplete state and result in user dissatisfaction and the project failure. Therefore it is a very important task to properly assess the TRL for a successful project. In this study, We propose the method for risk management of core technology R&D project of the defence area using the QFD process with degree of difficulty and technology readiness level. It is also presented the process to determine the risk level using TRL and Degree of difficulty. Finally We apply this method to UGV system for verifying the result of this study.
