This project continues the principal investigator's experimentation with algorithmic methods for the design of complex processes that are difficult to operate and control; that is, processes that are often overdesigned because process engineers are reluctant to design near or within regimes of complex operation, where these processes are often economically optimal. To achieve better designs, work will continue to investigate development of design methodologies that involve the coordination of design, operations, and control optimizations. The prototype software system, PRODOC, will be extended to permit experimentation with new methodologies for eliminating overdesign in a broader class of chemical processes. In these new methodologies, models for design and control are refined in a coordinated fashion as the design evolves. A Model Predictive Controller (MPC) developed previously, enables the improved control needed to operate near or within complex nonlinear regimes. MPC optimization is coordinated with economic optimization to efficiently evaluate the controllability of the most promising designs as the economic optimization proceeds. The project is concerned with two typical chemical processes for experimentation with the new algorithms and design methodologies. It extends and perfects the optimization techniques for locating all solutions, including the global optimum, of complex nonlinear programs, such as arise when implementing the new design methodologies. The contributions, which can be expected to advance the state-of-the-art for all design engineers, are beginning to have an impact on chemical process engineers, who are gaining the ability to reliably design more highly-integrated chemical processes that are more energy- efficient and profitable.

该项目继续使用算法方法进行主要研究者的实验，以设计难以操作和控制的复杂过程；也就是说，由于过程工程师不愿意在复杂操作的方案附近或之内设计，这些过程通常在经济上是最佳的。 为了实现更好的设计，工作将继续研究涉及设计，操作和控制优化的设计方法的开发。 原型软件系统（Prodoc）将扩展，以允许使用新方法进行实验，以消除在更广泛的化学过程中过度设计的方法。 在这些新方法中，随着设计的发展，设计和控制模型以协调的方式进行了完善。 先前开发的模型预测控制器（MPC），可以在复杂的非线性方案附近或内部操作所需的改进控制。 随着经济优化的进行，MPC优化与经济优化协调，以有效评估最有前途的设计的可控性。 该项目与新算法和设计方法相关的两个典型的化学过程有关。 它扩展并完善了用于定位复杂非线性程序的所有解决方案（包括全局最佳）的优化技术，例如在实施新设计方法时出现。 可以期望为所有设计工程师推动最先进的贡献，他们开始对化学工艺工程师产生影响，这些工程师正在获得可靠设计更高度综合化的化学工艺的能力，这些工艺具有更高的能源和有利可图的。
