Methodology, Applications & Progress
§1 Introduction
Background for New Methodology
Modern natural science methodology is mainly based on
matter and energy.
Even though matter and energy are still necessitate factors
in information system, yet the characteristic feature of
information systems, particularly plex ones, is
neither matter nor energy, but information.
Without information, plex information systems, like
brain and intelligent life, cannot be understood.
The Weakness of Old Methodology
Structuralism (Matter) – The Same Function May Have
Different Structure
Functionalism (Energy) – The Same Function May Have
Different Mechanisms
Information – Central Mechanism plex Systems
§2 Methodology of Informatics
-- Information (Mechanism) analysis plex systems
-- Information (Mechanism) synthesis plex systems
-- Information (Mechanism) evolution plex systems
The related criteria of the methodology include:
The main body of the methodology includes:
-- The trinity of matter, energy, and information;
-- The trinity of structure, function, and behavior.
Mechanism for Intelligent System
Information
Knowledge
Intelligence
§3 Implications of The Methodology
It plementary to the traditional methodology .
The applicability of the methodology is mainly in plex
systems, like intelligence, biological function and b
