Dismantling closed industrial plants of huge sizes and complexity (e. g. nuclear power plants or oil refineries) is a big challenge concerning the planning and scheduling of the logistical processes. If a plant is dismantled and the components are postprocessed on-site, e. g. due to safety regulations demanding special controlled areas in nuclear facilities, often logistical deficits are resulting. If disassembly and postprocessing are not coupled close enough often massive fluctuations of the working systems workload are resulting. A long duration of the whole dismantling process, high inventories of work in progress and alternating short- and over-capacities are the result. This can decrease the economic efficiency of a dismantling project. An approach for a combined control of disassembly and postprocessing considering the specialties of plant dismantling does not exist yet. The objective of this research proposal is to develop an approach for a combined control of disassembly and postprocessing processes in the field of plant dismantling. The approach shall start disassembly activities for specific parts of the plant considering sequence dependent restrictions in such a manner that a constant workload of the postprocessing working stations is achieved. It is also aspired to minimize the buffer stock of work in progress between disassembly and postprocessing. Also knowledge shall be generated concerning the limitations of the achieved approach. The question shall be answered, if a shifting of workloads by controlling the disassembly sequence can improve logistical goals compared to an isolated control of disassembly and postprocessing.

拆除大小和复杂性的封闭工厂（例如，核电站或石油炼油厂）是关于后勤过程的计划和安排的巨大挑战。如果拆除植物并且组件被后处理，则在现场进行处理。 g。由于要求在核设施中进行特殊控制区域的安全法规，通常会导致后勤缺陷。如果拆卸和后处理没有足够接近，则经常会导致工作系统的大规模波动。结果是整个拆卸过程的长时间，正在进行的工作中的高清单以及交替的短期和过度景点是结果。这可以降低拆卸项目的经济效率。考虑到植物拆卸的专业，拆卸和后处理的联合控制的方法尚不存在。这项研究建议的目的是开发一种方法，以共同控制植物拆卸领域的拆卸和后处理过程。该方法应开始为工厂的特定部分拆卸活动，以依赖序列限制的方式，以使后处理工作站的持续工作量。也渴望最大程度地减少拆卸和后处理之间正在进行的工作缓冲库存。同样，应就达到的方法的局限性产生知识。如果通过控制拆卸序列可以通过控制拆卸和拆卸后处理的拆卸序列来改善后勤目标，则应回答问题。
