To control a discrete event system, a supervisor is introduced which enables and disables events in order to prevent undesirable behavior, that is, the events that violate safety and other constraints. It is proposed that, in some applications, a supervisor can take chances by not preventing undesirable behavior that has very small probability of occurring. This can lead to better performance. A concise and "logical" model is also proposed, which allows us to combine controlled systems using conjunction, disjunction, shuffle and sequential compositions. Forceful controllers are then introduced, which force an event if a given condition is true. Finally, decentralized and hierarchical control are formalized. Conditions for decentralization will be investigated. If this research is successful, it will enhance the applicability of the theory of supervisory control to complex discrete event systems such as manufacturing systems, computer and communication systems.

为了控制离散事件系统， 引入了管理程序， 禁用事件以防止 不受欢迎的行为，即， 违反安全和其他限制。 是 建议，在某些应用中， 监管者可以冒险不去阻止 不受欢迎的行为，有很小的 发生的概率。 这可能导致 更好的性能。 一个简洁而“逻辑”的 还提出了一个模型，它允许我们 使用合取来联合收割机控制系统， 析取、混洗和顺序 组合物的 强有力的控制者 如果一个给定的 条件为真。 最后，去中心化和 形式化分级控制。 权力下放的条件将是 研究了 如果这项研究成功， 它将增强 复杂系统监控理论 离散事件系统，如制造业 系统、计算机和通信系统。
