Since variety of construction projects with their individual specifications could be handled through different procurement systems, selection of the most appropriate project delivery system is a vital step towards more efficient project execution. The appropriate selection of project delivery system may also ensure more competent management of the project. Its impacts are not only limited to the first stages of the project, as it could also influence pre-construction, construction and operational phases of the project. Among different approaches exerted for this purpose, none has taken uncertainty into account, despite the fact that during first stages of the project most of the selection factors are still uncertain and not clearly defined. This paper, hence, aims to provide a fuzzy insight into the project delivery system selection. Through this approach more tangible model of the evaluation process may be presented. Proposed fuzzy method is indeed a multi criteria decision making model, based on the group of criteria, assigned for the evaluation procedure. A case study is also conducted, based on the opinion of an invented group of the experts.

The selection of an appropriate contract method is vital for the successful operation of the project. However, there has been a lack of studies on objective decision making support models for use in the planning stage of a project contract. The present study had the goal of analyzing the factors that influence contract method selection, as an initial study for developing a project contract method selection model. The existing related studies were analyzed, and the factors considered in the literature were selected. Then, based on the findings, the opinions of an expert group on the important factors for contract method selection were collected through a survey. The collected opinions were analyzed using factor analysis, a statistical analysis method. The results will be utilized in the future as preliminary data for developing a decision making model for selecting a contract method.

오늘날 건설수요는 고도화, 프로젝트의 대형화, 공사여건의 복잡화와 같은 외부환경에 의해 변하고 있다. 이에 정부에서는 외부환경의 변화에 적절히 대응하고자 선진화된 발주방식을 도입하였다. 그러나 이러한 의도와는 달리, 기 발주된 프로젝트에서는 발주방식별 장${\cdot}$단점 등이 효과적으로 나타나지 못하고 있다. 이러한 원인은 사업의 기획단계에서 발주방식을 선정할 때 사업의 특성을 충분히 반영하지 못하는 현재의 "대형공사 입찰방법 심의기준"에서 그 원인을 찾을 수 있다. 따라서 본 연구는 프로젝트의 특성에 따른 적절한 발주방식을 적용하기 위하여 발주방식 선정기준을 위한 모델을 제시하고자 한다.

건설공사는 복잡화, 다양화, 대형화 되고 있으며 이러한 다변화된 건설 환경에 대응하기 위해 건설 선진국에서는 다양한 발주방식을 도입 적용해 오고 있다. 국내에서도 지속적으로 발주제도를 개선해 오고 있으며, 최근에는 공공건설공사의 발주방식을 보다 다양화하려는 취지에서 국가계약법시행령 개정을 통해 "기술제안입찰", "설계공모 기술제안입찰"을 새로 도입하였다. 이러한 정부의 노력에 부합되도록 공공공사에 적절한 발주방식선정기준이 제시되어야 한다. 이에 본 연구에서는 기 발주된 건설 공사 실태 및 현황분석을 설문조사를 통하여 문제점을 정리하였고, 이 문제점에 대한 개선방안으로 사업유형별 발주방식 선정기준을 제시하였다.

On the situation cooperating with business partners on the supply chain, systematic decision making process is a critical issue for them. The two major issues of purchasing strategy such as selecting vendors and managing them are important part of their overall business activities. This study mainly focus on the former issue of the vendor selection. Through the empirical study, analytical hierarchy process (AHP) method was applied to select vendors among supplier vendors based on four selection criteria such as the level of quality, product on management ability, delivery, and price. The results of study showed the main criteria of vender selection was the ability of quality management. The vender selected based on AHP and the current selection method was different, but implicitly projected the dilemma situation between quality and price which occurs in decision making process of real life.

The supplier selection problem is perhaps the most important component of the purchasing function. Some of the common and influential criteria in the selection of a supplier include quality, price, delivery, and service. These evaluation criteria often conflict, however, and it is frequently impossible to find a supplier that excels in all areas. In addition, some of the criteria are quantitative and some are qualitative. Thus, a methodology is needed that can capture both subjective and objective evaluation measures. The Analytic Hierarchy Process(AHP) is a decision-making method for ranking alternative courses of action when multiple criteria must be considered. This paper proposes the AHP-based approach which can structure the supplier selection process and the achievements-based procedure which can allocate order quantities for the selected suppliers In automotive part manufacturers. Also, through the practical case of 'D' automotive part manufacturing company, we shows that the proposed AHP based supplier selection approach and the achievements-based allocation procedure of order quantity can be successfully applied for supplier selection and order quantity allocation problems.

Purpose: This study was to examine the degree of prenatal emotional status, preparation for delivery, postpartum social support, and postpartum blues and to investigate the relationship of the above variables in postpartum women. Method: The subjects were 131 postpartum women. Selection criteria were women who were 2 to 8 weeks post delivery. After Informed consent was obtained, they were asked to fill out a self-administered questionnaire. The instrument was a Postnatal Depression & Anxiety check list. Result: The mean age of the subjects was 29.3 years, and 63.4% of subjects delivered their children by vaginal birth. 18.3 percent had felt depressed during their pregnancy. The mean score of the postpartum blues was 19.2. 61.8 percent of the subjects had postpartum blues and 8.4 percent experienced postpartum depression. Monthly income was negatively correlated to postpartum blues (r=-.189, p<.05), but the emotional status during pregnancy had a significant and positive relationship. However, preparation for delivery had no significant correlation with postpartum blues. While husband support and social support had a tendency to have a negative correlation. Conclusion: Further research is needed to identify the factors that affect the emotional status during pregnancy with various scales. Also, intervention programs to increase emotional support for pregnancy and husband support are needed.

대형마트보다 저렴하고 편의성도 높은 창고형 매장에 대한 물류 중요성이 증대되고 있다. 하지만 창고형 매장의 통합 Depot 위치선정에 관한 연구는 부족한 실정이다. 이러한 측면에서 본 연구에서는 통합 Depot 위치선정을 위한 요인도출 및 가중치 산출, 대상지의 위치 우선순위 산정을 다기준 의사결정 방법인 AHP(Analytic Hierarchy Process)방법을 도입하여 계산하는 것을 연구의 목적으로 한다. 분석결과, 선정 요인별 중요도에서는 수배송 비용절감(0.198)이 가장 높게 나왔으며, 수배송 거리절감(0.168), 수배송 시간절감(0.149) 순으로 도출 되었다. 본 연구 결과는 Depot를 통합 운영 시 비용 절감과 효율성 증가를 수치화하여 실제 실무자들에게 보다 현실적인 기초자료를 제시할 수 있을 것으로 판단된다. 향후연구에서는 분석에 사용되는 요인의 추가작업을 통하여 분석모형을 정교화 할 필요가 있다.

Due to the rapid change of global business environment, the growth of China's steel industry and the inflow of cheap products, domestic steel industry is faced on downward trend. The change of business paradigms from a quantitative growth to a qualitative product is needed in this steel industry. In this environment, it is very important for domestic steel distribution companies to secure their competitiveness by selecting good supply companies through a efficient procurement strategy and effective method. This study tried to find out the success factors of steel distribution industry based on survey research from experts. Weighted values of each factors were found by using AHP (analytic hierarchy process) analysis. The weighted values were applied to DEA(data envelopment analysis) model and eventually the best steel supply company were selected. This paper used 29 domestic steel distribution firms for case example and 5 steps of decision process to select good vendors were suggested. This study used quality, price, delivery and finance as a selection criteria. Using this four criterions, nine variable were suggested. Which were product diversity, base price, discount, payment position, average delivery date, urgency order responsibility and financial condition. These variables were used as a output variable of DEA. Sales and facilities were used as an input variable. Pairwise comparison was conducted using these variables. The weighted value calculated by AHP pairwise comparison were used for DEA analysis. Through the analysis of DEA efficiency process, good DMU (decision making unit) were recommended as a steel supply company. The domestic case example was used to show the effectiveness of this study.
