  • In the MEP(Mechanical Electrical and Plumbing) field, the utilization of BIM-based drawings is lower than in the architectural and structural sectors, and the limited BIM collaboration problem caused by different levels of BIM utilization in each field is becoming a serious problem in adoption and utilizing BIM. Therefore, this study analyzed the current status of BIM application in the field of mechanical equipment in the construction industry and analyzed the practical problems and limitations of adoption and utilizing BIM from a corporate perspective based on Delphi analysis techniques. Based on the results of the analysis, the limitations of the current MEP BIM application were classified into economic, technical, institutional, and social factors to derive detailed items, and, accordingly, the improvement measures were classified as institutional, policy, and technical measures. As a result, the company intends to maximize the value of BIM utilization in the MEP field by presenting improvement plans to activate BIM in the field of mechanical equipment based on the opinions of the company, thereby laying the foundation for BIM in the construction industry by creating a collaborative BIM environment for each sector in the domestic construction industry.

  • This paper considers the reliability computation of the network with dependent components and a software system is developed for supporting the reliability analysis and improvement of the system reliability. At first, We propose the common cause failure and load sharing models as the typical models considering the dynamic behaviors of networks with dependent components. Secondly, the algorithm is proposed to obtain the network reliability and reliability importance of component. The software, Delphi, is used to develop the our reliability analysis system.

  • Many countries implement an offset program as a method of the acquisition of modern military technology for enhancement of the domestic military strength. Offset agreements are made based on the value, not a monetary unit. The value should be above minimum threshold fixed by the related regulation. Hence, technology valuation model which is objective and reasonable is required vitally. At present, some defense related organizations such as DTaQ, ADD valuate the proposed technology by using their own method. However, due to the lack of differentiation of valuation analysis indicators for various technologies, existing offset valuation models are inadequate to consider whole characteristics of such technologies. In this paper, we developed four sets of offset valuation analysis indicators considering the characteristics of each technology, parts production, depot maintenance, military equipment performance upgrade, and R&D related technology, by using the Delphi method. Also, we structurized those indicators in each technology by using the factor analysis. Through applying developed indicators, it is expected that technology valuation in the offset program would be more credible and accurate. Ultimately, it gives greater bargaining power to negotiators in the procedure of the offset negotiation.

  • Since CM for Fee has been introduced in domestic market of construction industry, Construction Management(CM) has been familiar with one of the established delivery systems in Korea. However, CM(CM for Fee) construction market has been stagnant consistently due to recent economic recessions. The fundamental causes of the current depression of CM construction market are highly related to the social/environmental factors(such as owner's negative perception about CM services, exclusive formation of the CM markets, unfeasible fee and limitations on technology developments in CM services) and the shortage of institutions associated with CM. Accordingly, fundamental improvements on the CM environment are required. This study suggests the feasible methods for improvement on CM system based on fundamental analysis of problems related to the environmental factors by conducting a delphi technique with professional personnels on various positions in CM markets.

  • Objectives: Tobacco control in Indonesia is very lenient compared to international standards. This study explored the perspectives of tobacco control stakeholders (TCSs) on the likelihood of advancing tobacco marketing regulation in Indonesia. Methods: Data were collected from TCSs who were members of the Indonesia Tobacco Control Network group in a modified Delphi study. We collected the data in 2 waves using a questionnaire that comprised a set of closed and open-ended questions. For this paper, we analysed 2 of the 3 sections of the questionnaire: (1) tobacco advertising, promotions, and sponsorship (TAPS) bans, and (2) marketing and retailing regulations. We conducted a descriptive analysis of the scores using Stata/IC.13 and summarised the comments for each item. Results: The TCSs viewed the measures/strategies across all aspects of TAPS and tobacco marketing regulation as highly desirable, but provided varied responses on their feasibility. They rated political feasibility lower than technical feasibility for most measures. Advancing TAPS measures and prohibition of selling to minors were considered more attainable by sub-national governments, while prohibition of tobacco corporate social responsibility was considered as the least feasible measure in the next 5 years. Conclusions: Despite little optimism for substantial national-level change, there is a positive expectation that sub-national governments will strengthen their tobacco control regulation. It is paramount that the government reduce tobacco industry leverage by implementing Article 5.3 of the World Health Organization Framework Convention on Tobacco Control. Extending advocacy networks beyond tobacco control groups and framing tobacco control more effectively are necessary steps.
