ABSTRACTPI: Luke E. Achenie Institution: University of ConnecticutProposal Number: 0438367Title: Collaborative Proposal: Large-Scale Optimization Strategies for DesignUnder UncertaintyResearch: Optimal design under unknown information is a key task in process systems engineering. This project considers formulations that incorporate two types of unknown information, uncertainty in the modeling information and variability in the operation of the process. Uncertainty requires an overdesign of the process so that it can operate over the entire uncertainty range. On the other hand, variability can be mitigated through effective control strategies. Nevertheless, both issues are present in most engineering systems and must be confronted at the design stage. To address this problem the PIs plan extend a two-stage formulation for design under uncertainty and derive new optimization strategies for this formulation. A key component of this proposal is the application of novel optimization algorithms, recently developed by the investigators.Broader Impacts: This approach will be applied to a number of important research problems in chemical processing, including modeling and optimization for fuel cells, carbon nanotubes and CVD reactors for the manufacture of semiconductors. In addition two important outreach activities include:- Distribution of developed software to assess the influence of uncertainty and variability in industrially-relevant processes- An educational program for high school students, undergraduates and high school teachers to recognize the impact of uncertainty and process variability on process performance, economics, safety and environmental impact.

摘要：卢克E。Achenie机构：美国康涅狄格大学提案编号：0438367题目：合作提案：不确定条件下设计的大规模优化策略研究：未知信息下的优化设计是过程系统工程中的一项关键任务。 该项目考虑了两种类型的未知信息，建模信息的不确定性和过程操作的可变性的配方。 不确定性要求对过程进行过度设计，以便它可以在整个不确定性范围内运行。另一方面，可变性可以通过有效的控制策略来减轻。然而，这两个问题都存在于大多数工程系统中，必须在设计阶段面对。 为了解决这个问题，PI计划扩展两阶段的配方设计下的不确定性，并得出新的优化策略，这个配方。这项建议的一个关键组成部分是新的优化算法的应用，最近开发的研究人员。更广泛的影响：这种方法将被应用到一些重要的研究问题，在化学处理，包括建模和优化燃料电池，碳纳米管和化学气相沉积反应器的半导体制造。此外，两个重要的推广活动包括：-分发开发的软件，以评估工业相关过程中的不确定性和可变性的影响-高中学生，本科生和高中教师的教育计划，以认识到不确定性和过程可变性对过程性能，经济，安全和环境影响的影响。
