本文介绍了状态空间方法在过程综合中的概念框架和应用。结果表明，状态空间方法包含了作为特例的网络上层建筑的概念。此外，通过不同的操作员，它被证明在制定过程网络综合问题时提供了更大的灵活性。作为例子，证明了赋值算子可以用来简化大规模问题的求解。在求解热质交换网络综合问题时，也采用了夹点算子。为了证明这种新方法的有效性，我们讨论了两个重要的问题。首先，开发了最小化热/质交换网络的年化总成本(TAC)的一步法。其次，解决了一个新的问题，即基于夹点的可分离热质交换网络最小效用成本的计算。
In this paper, the conceptual framework and applications of the State Space Approach to Process Synthesis are presented. It is shown that the State Space Approach contains the concept of a Network Superstructure as a special case. Additionally, through various operators, it is shown to provide increased flexibility in formulating process network synthesis problems. As an example, it is demonstrated that an Assignment Operator can be used to facilitate the solution of large-scale problems. Pinch Operators are also employed in solving combined heat and mass exchange network synthesis problems. To demonstrate the usefulness of this new approach, two important problems are discussed. First, a one-step procedure is developed that minimizes the total annualized cost (TAC) of heat/mass exchange networks. Next, a novel problem, namely the pinch-based calculation of Minimum Utility Cost for a separable heat and mass exchange network, is solved.
