Strategies for Using Advanced Computer Architectures in Designing Complex Chemical Processes

开发使用先进计算机体系结构的机器，例如使用矢量和并行处理的机器，可以使复杂化学过程的设计、模拟和优化变得更加有效，无论是稳态还是非稳态。然而，为了充分利用这种体系结构，流程流程图问题的表述，以及更重要的是，用于解决这些问题的求解算法，必须完全重新编写。这在化工工艺设计领域是一个重要的挑战和机遇。通过使用为这些架构开发的技术，可以实现真正的交互设计能力，这将极大地提高设计工程师的生产率，从而产生更安全、更高效和更低成本的设计。为了最有效地利用先进的计算机体系结构，使用基于方程的方法对复杂的化学过程进行稳态和非稳态设计、模拟和优化，制定了各种策略。这些技术涉及新的、复杂的重新排序方法，用于解决作为化学过程模拟基础的稀疏矩阵问题，以及许多其他解决这些问题的新想法。这样的技术正在各种各样的先进架构机器上实施。

The design, simulation, and optimization of complex chemical processes, whether steady-state or unsteady-state, can be made much more effective by the exploitation of machines that use advanced- computer architectures, such as those using vector and parallel processing. However, to take full advantage of such architectures, the formulation of the process flowsheeting problem, and, more importantly, the solution algorithms used to solve these problems, must be totally reworked. This is an important challenge and opportunity in the area of chemical process design. By using techniques developed for these architectures truly interactive design capabilities can be achieved that will greatly enhance the productivity of the design engineer and thus produce designs that are safer, more efficient and less costly. Strategies are developed for most effectively taking advantage of advanced computer architectures for the steady-state and unsteady state design, simulation and optimization of complex chemical processes using the equation-based approach. The techniques involve new, and sophisticated reordering methods for the sparse matrix problem that underlies chemical process simulation, as well as many other new ideas for the solution of these problems. Such techniques are being implemented on a wide variety of advanced-architecture machines.
