| 英文摘要: |
| A non-cooperative game model based on brittleness entropy is formulated for preventing cascading failure of complex systems. Subsystems of a complex system are mapped to the players of the game. The influence of collapsed subsystems to other subsystems is also taken into account in the definition of payoff function except for their own entropy increase. This influence is named brittleness entropy. Each player has two optional strategies: rational for negative entropy and irrational for negative entropy. The model is designed to identify the players who select an irrational strategy for negative entropy. The players who select the irrational strategy for negative entropy continue to compete for negative entropy after the recovery of ordered state and make other subsystems can’t get enough negative entropy to reduce entropy increase. It leads to cascading failure of the complex system in the end. Genetic algorithm is used to seek the solution of game model, and the simulation result verifies the effectiveness of the proposed model. The model provides a new way to prevent cascading failure of complex systems. |
