在化学工艺系统的设计和操作中，两类不确定性很重要：（1）连续工艺参数（产品需求、原料质量、反应动力学）的实现； (2) 离散状态（通常与设备可用性相关）。本文提出了一个将两种类型的不确定性纳入过程系统设计的通用框架。引入组合灵活性-可靠性指数（FRI）来衡量过程系统同时应对以下情况的能力：（1）（随机）参数变化； (2) 设备故障，通过明确考虑过程操作相互作用和约束。然后提出设计优化程序，以最小的投资成本和最大的平均利润获得灵活、可靠的工艺系统；简要讨论了可能包含的维护考虑因素。 >
In the design and operation of chemical process systems, two categories of uncertainty are important: (1) realization of continuous process parameters (product demands, feedstock qualities, reaction kinetics); and (2) discrete states (typically related to equipment availability). This paper presents a general framework for incorporating both types of uncertainty in process system design. A combined flexibility-reliability index (FRI) is introduced to measure the capability of a process system to cope simultaneously with: (1) (stochastic) parameter variations; and (2) equipment failures, by explicitly accounting for process operational interactions and constraints. A design optimization procedure is then proposed for obtaining flexible, reliable process systems at minimum investment cost and maximum average profit; the potential inclusion of maintenance considerations is briefly discussed. >
