Presentation Transcript

  1. Principles of System Analysis and their applicationto Economic Problems Solving

  2. Content • System Approach • System; System-wide patterns • System Modeling • Regulation and Control • Problems of Description of Complex Systems

  3. Types of Systems • causal | goal – aspiring • natural | artificial • real | abstract • static | dynamic • centralized | decentralized • well organized | poorly organized (diffuse) • adaptive systems | self-organized systems • complex systems

  4. System-wide Patterns • integrity • divisibility • hierarchy • emergence

  5. Model – a system designed to understanding properties of some other system

  6. Types of models • models of interaction with environment • content models • models of structure • cause – effect models • dynamic models

  7. Regulation and Control • Feedback mechanism • Feed-forward mechanism • Degree of ordering:

  8. Characteristics of Complex Systems • difficult to determine boundaries • (usually) non-equilibrium • (often) exhibit hysteresis • cascading failure • (may be) nested; economy -> organizations -> people • nonlinear relationships (butterfly effect) • complex feedback loops

  9. Behaviour of a Complex System • stable zone • intermediate layer (phase transition, “edge of chaos”) • Instability zone
