In [[applied physics]], the concept of '''controlling self-organized criticality''' refers to the control of processes by which a [[self-organized]] system dissipates [[energy]]. The objective of the control is to reduce the probability of occurrence of and size of [[energy dissipation]] bursts, often called ''avalanches'', of self-organized systems.  Dissipation of energy in a [[self-organized criticality|self-organized critical]] system into a lower energy state can be costly for society, since it depends on avalanches of all sizes usually following a kind of [[power law]] distribution and large avalanches can be damaging and disruptive.<ref name=cajand10a>

Several strategies have been proposed to deal with the issue of controlling self-organized criticality:

有人提出了几个策略来处理控制自组织临界性的问题:



  1. The design of controlled avalanches. Daniel O. Cajueiro and Roberto F. S. Andrade show that if well-formulated small and medium avalanches are exogenously triggered in the system, the energy of the system is released in a way that large avalanches are rarer.[1][2][3]

控制雪崩的设计 Daniel O. Cajueiro和Roberto F. S. Andrade的研究表明，如果配方良好的中小规模雪崩是由系统外部触发的，那么系统的能量释放方式将使大规模雪崩更为罕见。

  1. The modification of the degree of interdependence of the network where the avalanche spreads. Charles D. Brummitt, Raissa M. D'Souza and E. A. Leicht show that the dynamics of self-organized critical systems on complex networks depend on connectivity of the complex network. They find that while some connectivity is beneficial (since it suppresses the largest cascades in the system), too much connectivity gives space for the development of very large cascades and increases the size of capacity of the system.引用错误：没有找到与</ref>对应的<ref>标签

  1. The modification of the deposition process of the self-organized system. Pierre-Andre Noel, Charles D. Brummitt and Raissa M. D'Souza show that it is possible to control the self-organized system by modifying the natural deposition process of the self-organized system adjusting the place where the avalanche starts.引用错误：没有找到与</ref>对应的<ref>标签

  1. Dynamically modifying the local thresholds of cascading failures. In a model of an electric transmission network, Heiko Hoffmann and David W. Payton demonstrated that either randomly upgrading lines (sort of like preventive maintenance) or upgrading broken lines to a random breakage threshold suppresses self-organized criticality.引用错误：没有找到与</ref>对应的<ref>标签 Apparently, these strategies undermine the self-organization of large critical clusters. Here, a critical cluster is a collection of transmission lines that are near the failure threshold and that collapse entirely if triggered.

显然，这些策略破坏了大型关键集群的自我组织。在这里，一个临界集群是一组接近故障阈值的传输线，一旦触发，这些传输线就会完全崩溃。
