A STUDY FOR SECURING RATIONALITY IN PLAN-DECISION-MAKING

Abstract

Rationality of planning and plan itself for securing justifiability in plan-decision-making for an infrastructure, has not been clarified sufficiently. The paper constructs a body of notions consisting rationality in plan-decision-making and gives a theoretical suggestion for planning or a system or guidance for planning. On the basis of the knowledge about rationality developed in some fields and the characteristics of planning, four notions consisting the rationality in plan-decision-making are defined, and thirteen normative notions consisting these four notions are presented by considering rationalities defined in the past. Furthermore, how the notion of rationality is applied in legal judgments is analyzed.
