1159244IerapetritouSummary: Given the strenuous economic environment and the fierce competition that almost all industrial sectors have to face, a lot of research and development have recently focused on advanced manufacturing. The initiative that the president announced this summer to invest $500M on the Advanced Manufacturing Partnership (AMP) points in this direction. More specifically this effort targets the collaboration of industry, universities, and the federal government "to invest in emerging technologies such as information technology, biotechnology, and nanotechnology". There are already some steps towards this direction that aim in reducing the time to the market and increasing the efficiency of manufacturing processes. This proposal's objective is to develop approaches that can lead to more efficient product operations by incorporating the process dynamics into the production scheduling problem. The full coupling of process control and production scheduling can substantially increase production feasibility and optimality. However, simultaneous consideration of process control and scheduling problems is currently plagued by (a) the lack of communication between the associated research communities; (b) its computational intensity, and (c) the inherently complex nature of manufacturing processes.Intellectual Merit: We propose an integrated approach to address the problem of scheduling considering a closed loop implementation of control in a process level. This will result in more efficient utilization of resources most importantly in the face of disturbances. However the incorporation of control within the already complex scheduling problem results in a very difficult problem and conventional solution methods turn out to be inefficient. The main outcome we are targeting is to provide the decision maker solutions that are optimal in terms of production capacity and feasible in terms of process dynamics in the face of disturbance.To achieve this target, the following ideas will be investigated:1. Integration of closed loop control with short term scheduling following the basic idea of Model Predictive Control (MPC) strategy.2. Investigation of MPC integration using multi-parametric programming.3. Investigation of efficient solution methodologies for the integrated scheduling andcontrol problem.Broader Impact: The ultimate goal of this work is to optimize the production scheduling considering the details of process dynamics. Realistic case studies from chemical and pharmaceutical manufacturing will be utilized to test and verify the results of the proposed analysis tools. The impact of the proposed work goes beyond specific industrial sector since the general ideas and findings can be applied or extended to different types of production facilities. The educational component of the proposed work involves one graduate and two undergraduate students. Funding for the undergraduate students would be pursued through REU initiative. Students affiliated with program SUPER (Science for Undergraduates a Program for Excellence in Research) of Douglass College of Women will be actively involved with this project.

1159244Ierapetritou总结：鉴于严峻的经济环境和几乎所有工业部门都必须面对的激烈竞争，许多研发最近都集中在先进制造上。总统今年夏天宣布向先进制造合作伙伴关系 (AMP) 投资 5 亿美元的倡议就指向了这个方向。更具体地说，这项工作的目标是工业界、大学和联邦政府的合作“投资信息技术、生物技术和纳米技术等新兴技术”。已经朝着这个方向采取了一些措施，旨在缩短上市时间并提高制造流程的效率。该提案的目标是开发通过将流程动态纳入生产调度问题来提高产品运营效率的方法。过程控制和生产调度的充分耦合可以大幅提高生产的可行性和优化性。然而，同时考虑过程控制和调度问题目前受到以下问题的困扰：（a）相关研究团体之间缺乏沟通； (b) 其计算强度，以及 (c) 制造过程固有的复杂性。 智力优点：我们提出了一种综合方法来解决调度问题，考虑过程级别控制的闭环实现。这将导致在面对干扰时更有效地利用资源。然而，在已经很复杂的调度问题中加入控制会导致一个非常困难的问题，并且传统的解决方法效率低下。我们的主要目标是为决策者提供在面对干扰时在生产能力方面最优且在过程动态方面可行的解决方案。为了实现这一目标，将研究以下想法： 1．遵循模型预测控制(MPC)策略的基本思想，将闭环控制与短期调度相结合。 2．使用多参数规划研究MPC集成。 3．研究集成调度和控制问题的有效解决方法。更广泛的影响：这项工作的最终目标是考虑过程动态的细节来优化生产调度。将利用化学和制药制造的实际案例研究来测试和验证所提出的分析工具的结果。拟议工作的影响超出了特定的工业部门，因为一般想法和研究结果可以应用或扩展到不同类型的生产设施。拟议工作的教育部分涉及一名研究生和两名本科生。本科生的资助将通过 REU 倡议获得。道格拉斯女子学院 SUPER（本科生科学卓越研究计划）项目的学生将积极参与该项目。
