건축프로젝트의 성과향상을 위해 현장관리자들이 조직에 최선을 다할 수 있도록 효과적으로 관리하는 것이 중요하다. 또한, 현장조직은 끊임없이 의사결정을 하므로 조직에서 의사결정이 적절하게 이루어지는지가 성과에 많은 영향을 미친다. 따라서 본 연구에서는 현장조직의 성과향상을 위해 현장관리자의 의사결정 참여와 조직몰입의 관계를 파악하는 것이 목적이다. 연구 결과 현장관리자들은 의사결정을 할 때 사람 중심보다는 업무 중심으로 하는 성향이 높은 것을 알 수 있었다. 또한, 의사결정 유형에 따라 정서적 몰입에 차이가 있으며, 의사결정 참여도와 조직몰입 간에 약한 상관관계가 있는 것을 알 수 있었다. 본 연구는 현장조직의 직무수행관리 능력을 높이는 데 도움을 줄 수 있을 것이다.

최근 국내 건설산업에는 생산성 저하, 기능 인력 유입 부족, 품질 저하, 안전사고 증대 우려 등 다양한 문제점들이 나타남에 따라, 이를 해결하기 위한 대안으로 Off-Site Construction (OSC)이 주목을 받고 있다. 그에 따라, 건설 프로젝트의 주체들은 기존의 현장 타설 공법뿐만 아니라, OSC의 도입 또한 하나의 대안으로 고려를 하고 있다. OSC의 도입은 초기 단계에서의 의사결정이 매우 중요함에도 불구하고, 합리적인 의사 결정을 위한 방법론이 부족한 실정이다. 본 연구에서는 프로젝트 특성을 도출하여 그에 대한 공사 난이도 지수를 선정하고 각 공법별 cost model을 개발하여 표준 공사비를 산정하여 최종 공사비 점수를 도출하는 의사 결정 시스템을 개발하였다. 본 연구에서 개발한 의사 결정 시스템을 활용하여 초기 단계에서 OSC 공법의 효율적인 도입을 위한 의사 결정을 할 수 있을 것으로 기대한다.

LHR(Landfill Site Hazard Ranking Model) was developed for ranking the relative hazard of landfill sites by using the method of value-structured approach. LHR consists of combining a multiattribute decision-making method with a Qualitative risk assessment approach. A pairwise com parisian method was applied to determine weights of landfill site factors related. To determine the hazard of landfill site, hydrogeological factors, waste characteristics factors and receptors factors were evaluated by LHR. LHR can help decision-makers prioritization of remediation of landfill sites through the relatively convenient and concise evaluation method of landfill site features related. LHR focuses mainly on pathways of groundwater and surfacewater for evaluating landfill hazard to receptors including humans. To validiate the applicability of LHR, Nanjido Landfill site, Metropolitan Landfill site, and Hwasung Landfill site were evaluated.

국방 무기체계 연구개발 과정에서 관련 규정이나 지침에 명시되지 않았지만, 연구개발 주관기관 내부적으로도 합리적인 대안 선택의 문제가 많이 발생한다. 대안 선택에 있어서 합리적인 과정이 적용되지 않으면 사업진행에 차질을 초래할 수 있으며, 이로 인해 사업기간 연장이나 추가 자원이 투입되는 상황도 발생된다. 특히 국내 미사일 연구개발 시 시험평가를 위한 많은 의사결정 과제들이 도출되며, 대표적인 것 중의 하나가 시험장 선정의 문제이다. 대안이 되는 시험장의 우선순위만 판단해야 한다면 델파이 기법(Delphi Method)이나 분석적계층과정(Analytic Hirarchy Process)을 활용할 수 있지만, 비용의 투입요소가 고려된다면 자료포락분석(Data Envelopment Analysis) 더 적합하다. 본 연구에서는 미사일 시험 시 발생되는 다양한 의사결정의 문제들을 염출해 보고, 이를 합리적으로 해결할 수 있는 의사결정의 방법이 제시된다. 제시된 의사결정의 프레임워크(Framework)는 국외 시험장을 선정하는 문제와 연관하여 모의 사례연구(Simulated Case Study)로 적용 과정이 연구된다.

Purpose: In the case of mass disaster, the establishment of temporary medical facilities for the first aid and treatment is required for the stable accommodation of patients caused by the disaster. However, the criteria for decision making related to the deployment of field emergency medical facilities are not specified. So, The purpose of this study is to draw considerable factors needed for the deployment of field emergency medical facilities and to make proposal for site selection process of field emergency medical facilities on the basis of the factor. Methods: This study performs text mining of disaster-related laws, guidelines and documents to derive key factors affecting site selection, also proposes a decision making process and conducts virtual deployment to validate the process. Results: The key factors for the site selection derived as the size of the damage, the size of the DMAT inputs, the location of available place, and distance to the disaster base hospital. As a result of virtual deployment following proposed decision making process, It is confirmed that the site of field emergency medical facilities is changed depending on the type of disaster, even if the scope of the disaster damage was the same. Implications: The deployment of field emergency medical facilities requires a separate criteria for each type of disaster, not uniform, as a future research a quantitative approach of the criteria needs to be performed.

A spatial decision making process is needed when a local government tries to make polices and plans for eco-tourism in urban and regional site scale. This study aimed to suggest an assessment model to support spatial decision making on planning and making polices for eco-tourism. The model composes 6 stages of 'setting up ecogeographic territories'. 'value analysis method as ecotourism resources' 'synthetic assessing', 'grading values', 'selecting main resources for ecotourism' and 'spatial decision making support'. Applying the model to Shiheung city in Kyounggi province, validity was secured. By using the model, it was possible to make some decisions effectively such as selection of ecotourism resources, decision of the priorities of polices for ecotourism, and setting up the type of ecotourism to be introduced. In addition, by visualizing high valued resources and areas for ecotourism it w possible to support to make plans and policies effectively.

According to growing interest in environmental quality with improvements of a standard of living site selection problems such as waste landfill sites, caused regional conflicts. This study investigates a waste landfill estimation method that was used to for storage, management, analysis and display of environmental information provided by geo-spatial information system(GIS) and analytic hierarchy process(AHP) as a decision-making method. If GIS is integrated with AHP, site selection problems of environmental hatred facilities shall be able to be very useful, because of AHP with flexibility which appropriately reflects opinions of the related group.

Expectation and interest about e-CRM are rising for more efficient customer management in on-line including electronic commerce. The decision-making tree can be used usefully as the data mining technology for e-CRM. In this paper, the representative decision making techniques, CART, C4.5, CHAID analyzed the differences in personalization point of view with actuality customer data through an experiment. With these analysis data, it is proposed a new decision-making tree system that has big advantage in personalization techniques. Through new system, it can get following advantage. First, it can form superior model more qualitatively in personalization by adding individual's weight value. Second it can supply information personalized more to customer. Third, it can have high position about customer's loyalty than other site of similar types of business. Fourth, it can reduce expense that cost marketing and decision-making. Fifth, it becomes possible that know that customer through smooth communication with customer who use personalized service wants and make from goods or service's quality to more worth thing.

Construction management requires decision-making skills. Main approaches to training construction management students are: (1) analyzing sample situations involving decision-making; and (2) teaching logical decision-making procedures. The absence of 'pressure' factors in these approaches has significant impacts on the success of the training. The approaches also lack 'dynamic' effects that help create a spontaneous plan for construction projects where unforeseen changes and interruptions may occur. To minimize the adverse effects of the existing approaches, this paper proposes a framework for developing a web-based training system. The application is delivered as a game involving decision-making on the student's part in response to developments at the job-site, and where one student competes against another in an attempt to simulate a real-world scenario.

Social commerce is a subset of e-commerce that involves using social media, and user contributions to assist in the online buying and selling of products and services. Given the rapid growth of social commerce sites such as Groupon, Ticketmonster, and Coupang, it has become critical to understand customer purchasing decision-making processes in the social commerce environment. This study developed a theoretical model to examine the role of social commerce site's stickiness in customers' repurchasing decision processes. This study identifies price attribute, variety of selection, shopping enjoyment, and anger as the key factors of social commerce site's stickiness. Data collected from 164 users who had more purchasing experiences with social commerce for more than 7 months were empirically tested against the research model. The analysis results indicate that social commerce site's stickiness plays an important role in enhancing customer's purchasing behavior. Moreover, price attribute and shopping enjoyment significantly influence social commerce site's stickiness, whereas anger does not significantly affect consumer purchasing decision-making processes. However, contrary to our expectation, variety of selection negatively influences social commerce site's stickiness. The theoretical and practical implications of the findings are described.
