프로젝트 관리는 통합적인 노력으로 수행되어 어떤 분야에 대한 특정의 조치 또는 불이행은 다른 분야에 영향을 미치게 된다. 즉 프로젝트 범위의 변경은 거의 대부분 프로젝트의 원가에 영향을 미치게 되지만 팀 사기나 품질에는 영향을 미칠 수도 있고, 그렇지 않을 수도 있다. 이와 같은 상호작용은 종종 프로젝트 목표들 간의 다음 그림과 같이 상호절충(Trade-Off)을 필요로 하여, 특정 분야의 성과가 다른 분야의 성과를 희생해야만 향상될 수 있는 경우도 생길 수 있기 때문이다. 한 프로젝트의 성공적인 관리는 이와 같은 상호작용의 적극적인 관리를 필요로 한다.

In this study, the project manager-oriented organization model has been verified by analysing it with forming a clear definition of detailed unitary duty entity to develop current non-efficient CM system constituted by functional organization with the decentralized responsibility and apply the model As a result from verification that the model provides valid solutions by comparing it with the existing, the model is better than the existing in cost savings, target profit sales rate, total rate of new on sales. Moreover, various activities in cost savings and cases where improvement is feasible are executed. However, the model caused some problems in organizational operation, project management and in division of duties so this study proposed improving management method

The main purpose of this study is to analyze the impact of the cost estimates on the construction work in residential apartment housing facilities. The planning work of facility construction is roughly divided into five main tasks which are further broken down into the following: process plan (P1-P6), construction plan (C1-C5), environmental management plan (E1-E4), quality management plan (Q1-Q5) and the safety management plan (S1-S5). In this study these tasks were classified into 25 detailed planning duties and a statistical analysis was performed on each one to determine its impact on cost. Finally this study derives from major planning tasks for effective cost management through correlation between planning tasks, cost indicators and t-test.

The goal of the construction work in the past was to improve the efficiency through cost reduction and shortening the construction period. However, the importance of safety management has recently been emphasized, and the Ministry of Employment and Labor has set a goal of reducing the number of deaths caused by industrial accidents by half. As a result, institutional and legal improvements are pursued and the need for safety is emphasized. However, most construction companies, except for some large construction companies, are lacking in safety management. So, In this paper, we design and implement a safety management system for construction site using smart helmets and beacons.

Quality is the core competence for customer satisfaction in current competitive business environments. The manufacturing companies regard the quality as the success factor in enhancing competitiveness and foremost concept of the management innovation. But in many cases, the basis for the quality management and the action programs are not prepared yet. In construction industry, normally schedule and cost have priority over quality and the level of overall quality is relatively lower than other industries. This is caused by the vague quality goal and result-oriented management. This study suggests the quality performance indicators for measuring performance objectively, and develops the continuous quality monitoring system based on those indicators. By using this system, the quality improvement can be expected and corporate quality competitiveness can be ensured.

최근 우유 소비량 감소로 인한 분유 재고 증가, 원유생산할당제, 더 강화된 체세포 등급 및 유대산정 기준, 매년 증가되는 우유 생산 원가, 질병 및 환경 스트레스로 인한 젖소 유지 및 생산비용 증가 등으로 인하여 우리나라 낙농가들의 경영성적이 극도로 악화되고 있는 실정이다. 문제는 이러한 요인들이 단시일 내에 낙농가들의 의지와 노력만으로는 극복하기 어렵다는 점이다. 이러한 이유로 인하여 전국의 낙농가 수들은 점차적으로 감소하고 있고 앞으로도 이런 추세는 당분간 지속될 것으로 보고 있다. 그렇다면 어떻게 해야 우리 목장은 살아 남을 수 있을까? 답은 변화다. 그동안 관행적으로 해 왔던 사양관리나 환경관리, 구체적이지 못한 경영목표 관리, 소극적인 신기술 접목 등이 목장 경영 선진화에 큰 걸림돌일 수밖에 없으므로 이에 대한 혁신이 필요하다. 본고에서 목장 경영 선진화에 필요한 기술 경영 특히 스트레스 환경관리, 초산분만 월령 단축 및 적정 육성우 보유 개선 방안들을 중점적으로 다루려 한다.

Although there are many positive sides of the current fee-for-service payment schedule, there is a strong necessity to control the rapidly increasing national healthcare expenditure. The global budget is often mentioned as one prominent alternative for solutions. In this article, both microscopic and macroscopic approaches are considered to set the hospital medical expenditure budget. In a macroscopic aspect, the SGR model, which considers the financial limit of the healthcare system, is used to set the next year target budget. In addition, the DEA model is used to measure the inefficiency and cost recognition. In this article, the national medical target expenditure is distributed to an individual hospital based on the level of efficiency. By combining the SGR and DEA, it will be possible to set a real world applicable target medical expenditure budget model.

The main purpose of this study is to identify the tasks performed at the construction stage of apartment houses and analyze the major construction tasks that may affect the performance indicators and analyze the impact on project performance. Based on expert opinions through preliminary research, pilot data, construction database, and other research trends, domestic and foreign research trends are divided into five major tasks, and each is divided into process management (P'1 ~ P'6), construction management (C'1 ~ C'5), environmental management (E'1 ~ E'4), quality control (Q'1 ~ Q'5), safety management (S'1 ~ S'5). Subsequently, each major task was subdivided into 24 detailed tasks. An independent t-test was conducted to analyze the impact on cost. We compared the importance of achieving the project goal and identified the construction work of concrete important construction which affects not only the cost but also the schedule performance index for the degree of significance of less than 0.05.

공급망관리(SCM:Supply Chain Management)는 자신의 비즈니스를 개선하고자 노력하는 대부분의 기업들에게 있어서 핵심 목표가 되고 있다. 공급망최적화(SCO:Supply Chain Optimization)는 이러한 개선 노력의 중심 목표로서 등장했으며, 보다 높은 수준의 고객 만족을 제공하기 위해, 공급망 구성원들이 최상의 업무 수행 사례를 공유하여 공급망 상호작용의 최저 원가와 최고 효율 시스템을 개발하기 위한 조직화 된 노력을 의미한다. 이러한 공급망에서 성과를 내기 위해서는 각 구성 요소들 사이의 조정과 협력이 필요하다. 그러나 기업내부와 기업외부의 환경의 동적인 면으로 인해 이러한 조정에 어려움이 있다. 예를 들면 공급업체로부터 원자재 도착시간의 지연, 생산 설비의 고장, 작업자의 질병, 고객의 주문에 대한 취소 및 변경을 계획의 변화를 유발시킨다. 몇 가지의 경우에는 지엽적으로 다루어 질 수 있지만 대부분의 경우는 공급망의 여러 기능들 사이에서 다루어져야만 한다. 이에 따라 본 연구에서는 중소기업의 각 프로세스를 최적화시키기 위해 에이전트를 이용한 e-SCM 프레임워크를 구축하고, 시뮬레이션 기법을 통해 그에 따른 성과를 제시한다.
