Application of a grounded group decision-making (GGDM) model: A case of micro-organism optimal inoculation method in biological self-healing concrete

Abstract:

The importance of enhancing group decision-making and involving different professionals in decision-making process is a challenging issue in diverse disciplines, engineering, medicine, and also biotechnology. Literature review highlights the basic needs of integrative group decision-making. However, such an integrative group decision-making has not been yet applied in biology and biotechnology areas of research. Using an appropriate decision-making model will aid researchers in accurate experimental decision-making process. In this regard, this study developed an integrative group decision-making model called "Grounded-Group Decision Making (GGDM)" model. The current body of knowledge in group decision-making methods was investigated to understand shortcomings and constrains faced by previous researchers. Accordingly, this study developed the GGDM model which was specifically applied in biological self-healing concrete construction process. As a case of application, the GGDM was applied to validate constructability of diverse inoculation methods in biological self-healing concrete construction, including, vascular network, encapsulation, silica gel, active carbon, and direct use. The GGDM model was implemented within three (3) decision-making sessions. In conclusion, GGDM model provided considerably more accurate, integrative, and consensus-value-based results in validation of inoculation methods. In conclusion, "Adaptation" and "Benchmarking" methods were the most suitable methods in biological self-healing concrete construction process. Moreover, establishment of GGDM model will aid software development in biological decision-making process design in future. © 2013 Balaban Desalination Publications.
