为了解决在过程操作期间发生的各种破坏性事件，通常使用反应式调度。然而，现有的反应式调度技术的一个主要限制是响应时间，这可能会在生成新的调度时造成显著的延迟。为了提高反应调度的效率，避免在调度过程中发生不确定事件时求解复杂的优化问题，提出了一种新的方法。该方法从多参数规划问题的解中得到无功调度，提前求解，覆盖了未来不确定性的所有可能结果。多参数规划问题源于一种新的反应调度公式，该公式将扰乱事件(抢修和机器故障)作为不确定参数加入到过程建模中。最后给出了几个算例，说明了该方法的有效性。美国化学工程师学会学报，54：2610-2623,2008
To address the various disruptive events that occur during process operations, reactive scheduling is commonly used. However, a major limitation of the existing reactive scheduling techniques is the response time, which might cause significant delay while the generation of a new schedule takes place. In this article, a novel approach is proposed to improve the efficiency of reactive scheduling and to avoid the resolution of a complex optimization problem when uncertain event occurs during the scheduling period. In the proposed method, reactive schedule is obtained from the solution of multiparametric programming problem, which is solved ahead of time and covers all possible outcomes of future uncertainty. The multiparametric programming problem is derived from a new reactive scheduling formulation, which integrates disruptive events (rush order and machine breakdown) as uncertain parameters in the process modeling. Several examples are presented to illustrate the effectiveness of the proposed approach. 2008 American Institute of Chemical Engineers AIChE J, 54: 2610–2623, 2008
