Research paper : New research trends in artifactology (J. OTA et al.)−209−Synthesiology - English edition Vol.7 No.4 (2015) were insufficiently dealt with in Phase II, we consider dealing with them in Phase III. This has been added to the paper.3 Modeling of individualsComment (Motoyuki Akamatsu)The article writes about modeling of individuals, but I was unable to grasp what this is based on just the description. Furthermore, the experimental economics approach is given as a case example, and I infer that it is employed as an experimental method to perform modeling of individuals, but no hypothesis is provided on what is a required condition for the modeling of individuals or what kind of functionality is made possible in the experimental system if this condition is met. I think that writing such hypotheses would enable readers to understand it as a concrete approach to achieve the center’s mission.Comment (Masaaki Mochimaru)“Modeling of individuals” is an important term in the research approach in Phase III. However, the reviewer has not been able to form an explicit understanding of this “modeling of individuals.”Answer (Jun Ota)Regarding modeling of individuals, we have firstly amended the description of the hierarchical structure. For simplicity’s sake, individuals in one box are considered to be expressed in its lowest part, and these are modeled in the form of interaction between homogeneous elements in the top position of the box immediately below (each having an internal state, and for this state different values can be taken). In this case, the internal state of the elements and the differences in interaction form the diversity of the individuals, and its dynamics form the dynamics of the individual. On that basis, we treat the individuals as agents and perform modeling from the perspective of three processes, namely, recognition of individuals, activities of individuals based on recognized results, and value construction of individuals, which underpins the generation of these activities. The aforementioned interaction is mainly expressed in the steps of recognition of individuals and activities of individuals, and the interaction and mediation among multi-stakeholders can then also be expressed. We have added an explanation to this effect. This is modeling of individuals.Regarding the experimental economics approach, modeling is easy in the case of singular agents since behavior is rationality based, but in the case of multi-stakeholder systems, because of the interdependence of each agent’s values, how each agent behaves is not well understood. Methods in experimental economics contribute to the model development of that aspect. Through experimental economics the experimenter induces specific utility functions in the subject, observes the behavior within a virtual social system where even utility is controlled, and, by looking at each actor’s utility change and overall social surplus, it becomes possible to deal with this explicitly as value. This method enables the modeling of the process of “value construction of individuals” outlined in chapter 2. This has been added to the paper.4 Socialization technologyComment (Motoyuki Akamatsu)As the initiative in Phase III centers on explaining experimental economics research, I think the approach of research relating to socialization technology has not been emphasized in concrete terms. As this is research that will be conducted from now onward, I do not think it can be easily organized along the lines of the framework, but for the reader to understand this emphasis it is desirable that it is adjusted to the extent that the overall article is organized in a logical manner.Answer (Jun Ota)As you have pointed out, the paper contained little discussion of socialization technology and we have therefore made an addition to this effect. Multi-stakeholder environments themselves are considered to be strongly linked to socialization technology. We have described the correspondence relation in figures 4 and 6. “Analysis” corresponds to problem setting, “function design” and “system design” to derivative analysis, “provision” to manufacturing, and “receipt” to evaluation and maintenance. This means that modeling of individuals is performed while problem setting (corresponding to socialization technology) is conducted based on the results received in the step immediately prior to “analysis.”
