We present a framework for the formulation and solution of continuous process scheduling problems. We focus on modeling transient operations such as startups, shutdowns, and transitions between steady states. First, we show how the concept of processing tasks can be generalized to represent continuous processes, including their transient operations. Second, we discuss how to systematically calculate the parameters describing material consumption/production and utility consumption during transient operations. Finally, we present new mixed-integer linear programming formulations for the scheduling of continuous chemical production.

连续化学过程调度的通用框架和优化模型

我们提出了一个用于制定和解决连续进程调度问题的框架。我们专注于模拟瞬态操作，例如启动、关闭和稳态之间的转换。首先，我们展示了如何将处理任务的概念推广到表示连续过程，包括它们的瞬态操作。其次，我们讨论如何系统地计算描述瞬态操作期间的材料消耗/生产和公用事业消耗的参数。最后，我们提出了用于连续化学品生产调度的新混合整数线性规划公式。
