The grant provides funding to develop methodology and tools to improve the material and product flows in collection and processing recycling/reuse networks. Collection system growth and perseverance decisions along with product lifecycles are key determinants of overall system flow potential, and will be modeled via stochastic dynamic programming with an hierarchical approach to plan strategic collection network growth while lower levels determine network operation and logistics. Long term system success requires relationship negotiation among various interdependent collection and processing agents with individual profit objectives and unwillingness to reveal confidential information as products, transportation/processing costs, and markets shift, so a methodology will be developed to determine equilibrium acquisition prices as well as mathematical flow allocation mechanisms between tiers of collectors and processors. Understanding the potential impact of uncertainty on key decisions will be facilitated by determining pivotal scenarios using state of the art methodology for large scale robust optimization. These approaches will be used to develop a deeper understanding of global material flows over time and product lifecycles. Interactions with the carpet and electronic companies will allow these tools to be tested and refined in a variety of contexts.Working with companies, non-profits, and government agencies, the results will enable better decision making for growing collection networks and connecting them with processing capabilities, with practical application to the carpet and electronics industries. The results contribute to the knowledge base for complex supply chain decision-making, both by making the problem representation richer and by developing new approaches for solving large-scale problems in the context of supply chain design. Student researchers and industrial partners will gain exposure to a rich class of problems of significant importance to modern industrialized societies and a set of techniques that can be brought to bear on a wide range of decision-making problems.

该赠款提供资金，用于开发方法和工具，以改善收集和加工回收/再利用网络中的材料和产品流动。 收集系统的增长和毅力的决定沿着产品的生命周期是整个系统的流量潜力的关键决定因素，并将通过随机动态规划建模与层次的方法来规划战略收集网络的增长，而较低的水平确定网络的运作和物流。 长期系统的成功需要各种相互依赖的收集和处理代理商与个人的利润目标和不愿意透露机密信息的产品，运输/加工成本和市场的变化之间的关系谈判，因此，将开发一种方法来确定均衡收购价格以及数学流之间的分配机制层的收藏家和处理器。 了解不确定性对关键决策的潜在影响，将有助于确定关键的情况下，使用最先进的大规模鲁棒优化的方法。 这些方法将被用来加深对全球材料流动随时间和产品生命周期的理解。 与地毯和电子公司的互动将使这些工具能够在各种环境中进行测试和改进。与公司，非营利组织和政府机构合作，结果将有助于更好地制定不断增长的收集网络的决策，并将其与处理能力联系起来，并实际应用于地毯和电子行业。 结果有助于复杂的供应链决策的知识库，无论是通过使问题的表示更丰富，并通过开发新的方法来解决大规模的问题，在供应链设计的背景下。 学生研究人员和工业合作伙伴将接触到对现代工业化社会具有重要意义的丰富一类问题，以及一套可以用于解决各种决策问题的技术。
