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.

为了控制离散的事件系统，引入了主管，该主管可以启用和禁用事件，以防止不良行为，即违反安全性和其他约束的事件。 有人提出，在某些应用中，主管可以通过不防止发生极小可能发生的不良行为来冒险。 这可以带来更好的性能。 还提出了一个简洁而“逻辑”的模型，它使我们能够使用连词，脱节，洗牌和顺序组成组合受控系统。 然后引入有力的控制器，如果给定条件为真，则迫使事件。 最后，分散和分层控制被正式化。 将研究权力下放的条件。 如果这项研究成功，它将增强监督控制理论对复杂离散事件系统（例如制造系统，计算机和通信系统）的适用性。
