  • This research suggests the FD-AHP decision making model for Construction Projects which is composed of two main method to prevent a ranking invert situation ; First, to make the consensus of the experts consistent, we utilize Fuzzy-Delphi method to adjust the fuzzy rating of every expert to achive the consensus condition with the fuzzy linguistic presentation. Second, to handle vague linguistic presentation caused by expert's experiences and subjective judgement, we propose Fuzzy-AHP which is able to enhance precision of construction projects decision mating situation. Moreover, with the correlation analysis, we show that the validity of the FD-AHP model under a decision making task specially on where highly demanded expert's experiences and intuition.

  • This study was carried out to investigate TF(Technological Forecasting) of ISDN (Integrated Services Digital Network) by Delphi method. Since the technology of science has been developed rapidly, the necessity of TF, which can predict the future direction and intensities of technological progress, has been gradually recognized in various fields. Therefore the purpose of this study was to explore the normative statistical data so that our business or nation may have better decision-making with the TF of ISDN which will be come into in the 21st century, presenting the appropriate methodology to the application of methods.

  • The goal of this research paper is to respond to changing paradigms in urban planning and derive requirements needed for urban archiving for the purpose of urban growth. In this research, the Delphi research method was used twice on experts on urban archiving in order to derive areas and required elements of urban archiving. Moreover, each area and elements were formalized and categorized. The results of this research is as follows. In the 1st Delphi research, 6 areas (natural environment, liberal arts environment, historical and cultural environments, social and educational environment, industrial and economic environment, transportation and communication environment), a total of 62 elements. In the 2nd Delphi research, six areas, a total of 32 elements.

  • This research presents an analysis of some of the occupations associated with Korea‘s national strategic industries. Therefore, the objectives of this paper can be summarized as follows: By classifying existing occupations and identifying potential future ones, this paper will strive to present a systematic analysis of environmental related occupations. In order to achieve the objectives of this research, related literature was examined, a Delphi Survey was conducted. In order to select potential future occupations, this research used a qualitative method that involved interviews with specialists. More specifically, a Delphi Survey was used to collect the specialists' opinions. The potential occupations were selected using a three-prong procedure involving an analysis of related literature and materials, a Delphi Survey, as well the holding of conferences with specialists and visits to those in the actual field. Through this process, 33 different potential future occupations were selected.

  • We investigate into some problems related to Corruption Perception Index(CPI). Delphi method is a popular for obtaining CPI; it is a mean of systematically collecting and progressively refining information provided by a group of selected experts in order to obtaining the weight values of questionnaires. However, Delphi method hold low aspect, to some extent, for it is solely dependent upon the judgment of a few professionals. In this paper, we propose the measurement model for X in LISREL as alternative for gaining the weight values of questionnaires. We use the 1999 Seoul ACI(Anti- Corruption Index) for empirical study.

  • This paper shows that fuzzy set theory can be useful in modeling and solving job scheduling problems with uncertain processing times. The processing times are considered as fuzzy numbers(fuzzy intervals or time intervals) and the fuzzy Delphi method is used to estimate a reliable time interval of each processing time. Based on these time estimates, we then propose an efficient methodology for calculating the optimal sequence and the fuzzy makespan.

  • Recently, conservation and utilization of cultural heritage has been regarded as importance. So, various research papers about maintenance of the remains have been presented in many conferences. But most of researches have focused on introduction about maintenance methods and explanation about maintenance concepts of remains. And even in case of a few papers treated post-evaluation about maintenance of the remains the criteria of the evaluation has tended to somewhat subjective. So, the purpose of this study is to show the objective post-evaluation indexes which was developed by Delphi AHP methods. This research was proceeded in two stages. First, we arranged the evaluation index in a hierarchy to be made through the analyses about references and researches about maintenance of remains. 304 evaluation articles were elicited through the process. And then, elicited evaluation articles were classified with 'conservation' and 'utilization'. Second step was to figure out importance and validity of hierarchical evaluation articles with twice questionnaire surveys. This research used interval scale to comprehend validity and AHP method to evaluate relative importance of each other articles.

  • The objective of this study is to subdivide the tactical considerations (METT+TC; Mission, Enemy, Terrain & Weather, Troops available, Time available, Civil considerations) through Delphi method and prioritize those via AHP (Analytic Hierarchy Process). Though it has been taken for granted that the tactical considerations were inevitable for decision making relating to military operations, their segmentation and priority have not been studied sufficiently in military. The data for Delphi method and AHP were based on interview with military experts and questionnaires answered by those. Six tactical considerations were segmented into 34 sub-considerations by Delphi, and Six tactical considerations and 34 sub-ones were prioritized through AHP in attack and defense aspects. If the research results will be embedded into database of automatic command and control system (e.g. ACTIS; Army Tactical Command Information System), effective decision-making process will get easier and faster.

  • Purpose: Given the emergence of a new profession called a palliative care aide, this study aims to develop the scope of its practice using the Delphi consensus method. Methods: This study was participated by a panel of experts comprising 36 members who were involved in either hospice palliative care practice or making relevant policies. Through a four-step Delphi study, the feasibility of the duty, task and task element was examined. Among the results, items that scored over 4.0 out of 5.0 were selected. Results: The analysis of the Delphi study suggested four job duties, 15 tasks and 46 task elements to be included in the practice scope for palliative care aides. Conclusion: This study defined the scope of practice for palliative care aides, which is expected to prevent any conflict or confusion regarding their job and to promote the quality of their service.

  • Purpose: The purpose of this study was to develop a respiratory infection prevention program for the rural elderly in the post-coronavirus disease 2019 (COVID-19) era. Methods: The Delphi method was used to validate the contents of the program. Two rounds of Delphi surveys and one individual interview were conducted on four subjects and 16 categories with nine experts. Content validity was calculated using the content validity ratio (CVR) and coefficient of variation (CV). Results: This study verified the content validity of the existing program components, such as respiratory infection prevention characteristics, cough etiquette, correct hand washing, oral hygiene, correct tooth brushing, and exercise by walking. The study comprised 28 categories covering seven subjects, including the provision of knowledge and information about COVID-19, environmental management for respiratory infection prevention, and exercise training for immunity enhancement. Conclusion: This Delphi study examined the respiratory infection prevention program that was redesigned for the post-COVID-19 era and confirmed the validity of the educational contents. The findings of this study suggest that the program can be used practically for the prevention of respiratory infection among the rural elderly.
