Operability Analysis of Chemical Process Supply Chain Systems

流程供应链是一个设施网络，涉及从原材料供应商向客户采购、加工、仓储和分发材料和产品。供应链的运作对企业的盈利能力有很大的影响。日益激烈的市场竞争、全球商业环境、市场波动和产品需求变化要求加工厂被放在整个供应链的背景下考虑，而不是孤立的实体。这些驱动因素也提高了化工过程系统研究界对供应链运作的认识，导致近年来对过程供应链系统的建模、优化和控制进行了几项研究。为了在竞争日益激烈的市场中保持盈利，生产过程及其供应链需要对客户的需求和市场趋势以及原料和过程的可变性做出反应。这项研究的目标是开发定量方法来分析流程供应链系统在这种动态市场环境中令人满意地运行的能力。人们已经开发了用于过程工厂操作和设计的可操作性分析工具，但它们在过程供应链系统的扩展环境中的应用在很大程度上还没有被探索。在这项研究中，将开发一个基于优化的框架，用于过程供应链系统的分析，借鉴已建立的过程工厂运营分析方法。

A process supply chain is a network of facilities involved in the procurement, processing, warehousing and distribution of materials and products from raw materials suppliers to customers. The profitability of an enterprise is strongly influenced by the operation of its supply chain. Increased market competition, global business environments, market volatility and product demand variation require process plants to be considered within the overall supply chain context rather than as isolated entities. These drivers have also raised the awareness of supply chain operation within the chemical process systems research community, leading to several studies in recent years on the modeling, optimization and control of process supply chain systems. In order to remain profitable in an increasingly competitive marketplace, production processes and their supply chains need to be responsive to customer demands and market trends, as well as feedstock and process variability. The goal of this research is to develop quantitative methodologies for analyzing the ability of process supply chain systems to operate satisfactorily within such dynamic market environments. Operability analysis tools have been developed for process plant operation and design, but their application to the extended environment of process supply chain systems is largely unexplored. In this research, an optimization-based framework will be developed for the analysis of process supply chain systems, drawing on approaches that have been established for process plant operability analysis.
