化工行业产品生命周期缩短，导致需求在数量、地点和类型方面存在不确定性。模块化生产概念可用于更有效地满足此类多变的客户需求。与大规模工厂的集中生产相比，模块化工厂大大提高了供应链的战术灵活性。此外，生产设施可以灵活地打开、关闭和重新启动。模块化工厂可以在中期内搬迁，其生产能力可以通过工艺模块的变化进行重新配置。这项工作提出了新的混合整数规划配方的战术规划的生产网络在化工行业，这些配方规定的体积，位置和过程中的模块化工厂在生产网络中的多个周期的规划范围。以化工行业为例，在考虑不同需求结构的情况下，研究了模块化柔性的经济价值。研究结果对化工行业模块化生产技术的技术实施和发展具有一定的管理意义。
Shorter product life cycles in the chemical industry have led to uncertain demand in terms of volume, location and type. Modular production concepts can be used to serve such volatile customer demand more efficiently. Modular plants increase the tactical flexibility of the supply chain substantially compared to centralized production with large-scale plants. Furthermore, production facilities can be flexibly opened, deactivated and reactivated. Modular plants can be relocated in the medium term, and their production capabilities can be reconfigured via process module changes. This work proposes new mixed-integer programming formulations for the tactical planning of production networks in the chemical industry; these formulations prescribe the volume, location, and process of modular plants in the production network over a multi-period planning horizon. The economic value of modular flexibility is investigated in a case study from the chemical industry under the consideration of diverse demand structures. The results have several managerial implications for the technical implementation and development of modular production technology in the chemical industry.
