건설산업관리는 건설사업의 초기부터 완성에 이르기까지 범위, 시간, 비용, 품질 등 관련 요소에 대한 통합 관리를 통해 프로젝트를 성공적으로 완수하기 위한 조직적 활동이며, 이의 궁극적 목표는 전사적 경영효율을 극대화하는 것이다. 이를 위해 관리자는 작업의 범위와 방법과 순서 및 비용과 일정을 계획, 실행, 감시 및 통제하며 그들에 수반되는 자원을 할당하고 조정한다. 자원배분은 공기 및 비용과 밀접하게 연관되고, 따라서 이들 관계에 근거한 효과적 자원배당은 하나의 의사결정문제로 모형화될 수 있다. 여기서 문제를 구성하는 의사결정기준과 대안의 성과뿐만 아니라 가중치 또한 중요한 기능을 하므로, 이들의 산정에는 일관성과 객관성이 담보되어야 한다. 본 논문은 다수의 의사결정기준하에 동시에 계획된 단일(복수) 프로젝트(현장)에 속한 활동들간에 한정된 동일 자원의 효과적 투입을 위한 우선순위를 결정하는 개념과 방법을 제시하였다. 기반 도구로 다기준 의사결정기법의 하나인 계층분석법을 활용하였으며, 세 가지 유형의 사례에 적용하여 그에 대한 타당성과 유용성을 보였다. 사례 1은 각 활동이 주공정상에 위치하며 선택기준으로 조기종료시간, 잔여후속공기, 후속활동수, 자원요구량 등을 선정하였으며, 사례 2는 경쟁 활동이 상이한 여유시간과 조기종료시간, 자원일수, 후속잔여공기, 후속활동수 등을 의사결정속성으로 선정하였다. 사례 3은 이미 수행된 4개의 농사에 대해 본 연구의 방법을 피드백하여 유용성을 검토하였다.

The Pusan Container Terminal faces a rapid increase in berthing time of container ships as well as in waiting time of external trucks, which is due to an absolute lack of yard space. This research is focused on the development of a decision support system for the planning of the container terminal yard assignment so that the yard space would be utilized most effectively. Efforts should be given to the reasonable assignment of the yard storage and the dynamic adaptation to the ever changing environment. The software introduced here is based on the know-how of the field exports and its framework takes the approach of the hierarchical decision making.

The international oil majors have been reducing the size of their own oil tanker fleet since early 1980s. Like international oil majors, the Korean refineries are becoming more dependent on tanker chartering rather than tanker ownership for their oil transportation since the 1990s. They also prefer spot charter to time charter and this kind of trend has continued up to now. Consequently, this paper attempted to find the factors influencing changes in tanker fleet composition. To attain the object of the paper, an empirical study is adopted using the ten decision-making factors derived from preceeding studies. The findings are that MARPOL and OPA 90, and transportation costs are the most important factors influencing an oil tanker fleet composition.

This study focus on oriental way for Win-win leadership of modern time using systems thinking approach. We constructed concept, 'Modesty Leadership' from oriental bible- Tao Te Ching, Change Ching, the Analects of Confucius. This work described in the paper based on case collected from 2011 Seoul city mayor election in the Korea. There are three initial aims : to confirm what feedback loop affected approval rating, to determine how these feedback interacted and to establish the significance of cognitive mapping. The use of system thinking to model cognitive mapping of political election untraditional approach in study of oriental bible. This approach is valuable in that it can be to understand management strategies and their effect on decision making.

Traditionally, the evaluation and selection of suppliers have been a major purchasing function. A growing concern for just in-time purchasing, global sourcing, and long-term partnership between buyers and suppliers makes selecting a righ supplier become more critical decision making process. Consequently, a rigorous and systematic method for evaluation suppliers is a must. However, assessing the values of factors(e.g. qulaity , delivery, and service) selected for evaluating suppliers contains elements of uncertainty. Although several methods have been developed for uncertainty analysis, they may not be proper tools for evaluating suppliers under uncertainty. In this paper, a methodology using a fuzzy-set approach in combination with a multicriterion decision-making (MCDM) technique is developed to use as a tool for evaluating suppliers under uncertainty. An numerical example is presented to demonstrate the method in practice.

We consider the question of warranties for repairable items. During the warranty period, each time an item fails the manufacturer has the obligation to restore the item to operational condition either by repairing the item or by replacing it by a new item. In this paper, we consider a warranty policy for making this decision based on the condition of the failed item. For products with phase-type lifetime distributions where the phases represent the condition of the item, we develop algorithms to determine the expected cost of servicing a warranty and use it in making the repair/replacement decision. illustrative numerical examples are presented.

When the large-capacity Mold type Transformer was passed through rain, after it was dried and it's parts were changed, Insulation Diagnosis was made to evaluate the condition of it and decide to recharge. Using the evaluation of Insulation Diagnosis, the urgent decision-making for recharge made blackout time minimum. In this study, it was considered that Insulation Diagnosis for the large-capacity Mold type Transformer is applied to decision-making for reuse of high voltage electric power equipment by analysis of the case study.

The purpose of this study is to provide necessity of job stress management to chief executives officers at small and medium size printing companies. At the same time, this study offers information of successful job stress management. When managing job stress is successfully accomplished, it increases job involvement of workers and brings high productivity eventually. Independent variables are decision-making right at the job, insecurity of job, and unreasonable reward at the company, while job involvement is dependent variable at this study. After analyzing data gathered, decision-making right influences job attachment and pursuing job outcome. And insecurity of job, that is the difficult job transferring, is significant to job accomplishment.

The intensive care unit (ICU) is the most common place to die. Also, ethical conflicts among stakeholders occur frequently in the ICU. Thus, ICU clinicians should be competent in all aspects for ethical decision-making. Major sources of conflicts are behavioral issues, such as verbal abuse or poor communication between physicians and nurses, and end-of-life care issues including a lack of respect for the patient's autonomy. The ethical conflicts are significantly associated with the job strain and burn-out syndrome of healthcare workers, and consequently, may threaten the quality of care. To improve the quality of care, handling ethical conflicts properly is emerging as a vital and more comprehensive area. The ICU physicians themselves need to be more sensitive to behavioral conflicts and enable shared decision making in end-of-life care. At the same time, the institutions and administrators should develop their processes to find and resolve common ethical problems in their ICUs.
