This paper discusses the problem of determining locations for public health-care facilities and allocating patients to the public facilities with the objective of minimizing the total construction cost. The public health-care facilities have two types of facilities: public hospitals and health centers. The public hospital provides both hospital services and homecare services, while the health center provides only homecare service. We present an integer programming formulation for the problem, and develop two types of heuristics, based on priority rules and approximate mathematical formulation. Results of a series of computational experiments on a number of problem instances show that the algorithms give good solutions in a reasonable computation time.

Technological forecasting for microprocessor market can provide timely insight into the prospects for significant technological changes in computer hardware as well as software. In this paper, we use bibliometrics to forecast R&D trend on microprocessor technology. Cumulative numbers of US Patents on several generations of microprocessor technology (pipeline, superpipeline, supersclar and VLIW) approved since 1980 are applied to fit diffusion models. Our study results provide both the maximum market potential and the maturity time for each generation of microprocessor technology. Such information is expected to make contribution on making better decisions with regard to strategic corporate planning, R&D management, product development and investment in new technology of microprocessor.

In these days, the technical advances and complexities have generated much of the difficulties in managing the project resources, both time and costing to accomplish the project in the most efficient manner. The project manager is frequently required to render judgements concerning the schedule and resource adjustments. This research develops an analytical model for a schedule-cost and risk analysis based on visual PERT/CPM. We used a two-step approaches ：in the step 1, a deterministic PERT/CPM model for the critical path and estimating the project time schedule and related resource planning, In the second step, we developed a heuristic model for crash and stretch out analysis based upon a time-cost trade-off associated with the crash and stretch out of the project. Computer implementation of this model is provided based on GUI-Type objective-oriented programming for the users and provided displays of all the inputs and outputs in the form of visual graphical. Also developed GUI-type program, Dongeui Visual-PERT/CPM. The results of this research will provide the project managers with an efficient management tool.

This study is focused on acquiring through understanding of the S&T level of Korea to serve as an important basis for the government policy-making and to make available basic information for promoting the National R&D Program effectively. the survey of S&T level is a comparison of the highest level in the world to that of korea in 3 digit of the technology tree table. And survey of technological gaps is determined by year which Korea is able to reach the current level of the advanced countries. The results of the surveys should be applied to strategic technology planning for solving or nar-rowing the technology gap and the major criteria for resources allocation in national R&D Pro-grams. The results of he surveys should be the fundamental information for establishing strategic S&T policy in government.

Technology analysis is to analyze technological data such as patent and paper for a given technology field. From the results of technology analysis, we can get novel knowledge for R&D planing and management. For the technology analysis, we can use diverse methods of statistics. Time series analysis is one of efficient approaches for technology analysis, because most technologies have researched and developed depended on time. So many technological data are time series. Time series data are occurred through time. In this paper, we propose a methodology of technology forecasting using the dynamic time warping (DTW) of time series analysis. To illustrate how to apply our methodology to real problem, we perform a case study of patent documents in target technology field. This research will contribute to R&D planning and technology management.

As the speed of technological changes increase with the investment requirements steadily expanding, private firms and government-funded research institutes experience similar pressures with respect to the necessity of risk reduction and technological alliances in R&D activities. This paper first attempts to review previous research in managing R&D projects with large, risky, and long-term investment requirements. Our primary focus is placed on the "fuzzy front-end" (FFE) projects with uncertainties at the investigation and planning stages. We analyze various elements that create FFE conditions, classify them into basic constructs, and suggest tools and methods to deal with FFE conditions. The findings suggest that both initial FFE conditions and the effectiveness of FFE management affect the performance of the project later on, and thus, especially for large projects, we must deal with FFE seriously in a comprehensive manner. We utilize in-depth panel interviews and case studies to approach the research questions.

네트워크 관리자는 트래픽 증가에 따른 네트워크 성능저하 문제를 해결하기 위해 개별 링크에 필요한 용량을 산정해야할 때가 있다. 대규모 네트워크의 경우 이산 사건 시뮬레이션만을 수행하여 용량을 산정하는 것보다 분석적 시뮬레이션을 함께 사용하여 용량을 산정한다면 시뮬레이션에 필요한 시간을 줄일 수 있다. 본 논문에서는 링크 용량계획을 위한 분석적 시뮬레이션의 활용방안을 논하고 그 기법을 기술하였다. 제안한 분석적 시뮬레이션 기법은 정상상태의 네트워크 분석이기 때문에 이산 사건 시뮬레이션에 비해 시뮬레이션에 소요되는 시간은 작지만 정확도는 낮다. 하지만 대규모 네트워크의 상태를 빠르게 파악하고 문제를 해결해야 한다면 좀 더 정밀한 시뮬레이션이나 분석을 위한 사전자료를 만들기에 충분할 것이다.

This study not only suggests a methodology of science planning different from technology planning, but also applies the methodology to the case of astronomy and space science project. Throughout the analysis on this practice, we have provided logical tools for science project planning, and have identified a decision making process in science which has been regarded to be in a 'black box'. Therefore, this science planning technique can contribute to a more rationalized allocation of scientific resource at a project level as well as at a national level. In particular, catch-up countries in a transition to post catch-up stage such as Korea can establish a more efficient national R&D system by application of science planning concept to an emerging technology area.

국가연구개발사업은 국가연구개발사업의 관리 등에 대한 규정 제17조에 의거하여 연구개발결과를 활용하는데 그 목적을 가진다. 그러나, 사실상 최근 국가연구개발사업을 통해 개발된 연구기술들은 특허 등의 라이선스를 획득하고 기술이전을 통해 사업화로 이어지는 사례가 매우 미미하다. 실제로 2005년 산업자원부의 조사에 따르면, 국가연구개발사업의 사업화 성공률은 평균 31.4%로 선진국의 1/2에도 못 미치는 수준이다. 따라서, 본 논문에서는 국가연구개발사업의 예산 대비 기술이전 및 확산을 통한 기술사업화 성공률을 높이기 위한 하나의 방법으로, 연구과제 평가 시 기술의 가치를 평가하여 그 평가결과를 예산배분에 반영 할 수 있도록 기술가치평가방법을 활용한 R&BD(Research &Business Development) 활성화를 위한 평가항목 및 개발될 기술의 사업성을 평가할 수 있는 평가모델을 설계하였다.
