Abstract
I submitted a thesis of "the concept of the Integrated Economic Rationality" as the management principle to the Journal of Business Management No.9. I got the Integrated Economic Rationality as the integrated concept consisting of four sub principles, that is, Environmental Principle, Human Principle, Social Principle and Economic Rational Principle. In former thesis, however, I had the following themes to dig. (1) to dig into four sub principles. (2) How to put the Integrated Economic Rationality into practice. I will make a study of Rationality in this thesis. The summary of this thesis is as follows. 1. Rationality mentioned in dictionaries: What does rationality mean in dictionaries (Japanese dictionaries and philosophical dictionaries), and then, after reference of the above -mentioned, I summarized the rationality. 2. Meaning of Rationality by management: In this section, I will make clear the following, management system from its active side and the meaning of rationality from the point of management-view. 3. The relations between the Integrated Economic Rationality, and H. A. Simon's rationalities and its premises. I understand the integrated economic rationality as what we take into consideration when we make a decision. I think that Simon's rationalities are to be also considered in case of the decision-making. Simon lists the following rationalities, that is, objective rationality, bounded rationality, substantive rationality, procedural rationality. I tried to make clear the relations between Integrated Economic Rationality, and Simon's rationalities and its premises. Integrated Economic Rationality corresponds to Simon's bounded rationality, and the means to realize the integrated economic rationality correspond to Simon's procedural rationality, and the success of the means to realize it corresponds to Simon's substantive rationality. Simon says that a rational decision can be viewed as a conclusion reached from premises of two different kinds; value premises and factual premises. I think, therefore, that the decision based on integrated economic rationality corresponds to the decision derived from Simon's two premises.
