Current trends, such as customers' demand for individual products and shorter product life cycles, are addressed by companies through a greater variety of products and variants. With regard to the line balancing of synchronized flow assembly systems, however, adjustments are associated with high investments, which requires a new methodology for assembly line balancing. Existing approaches do not consider the reallocation of work operations or the dimensioning of system-inherent flexibility and changeability according to requirements. Furthermore, they neglect the uncertainty of the future market situation. The proposed project aims at a methodology for the line balancing of synchronized flow assembly systems, taking into account the potential need for adaptation in order to meet this uncertain planning environment. For this purpose, the exchange of occurring costs as well as flexibility and changeability of the system is focused. Based on scenarios, potential future compositions of the variant mix are investigated and the resulting implications for the assembly system are derived. Within the proposed planning methodology, an adequate adaptable assembly line balancing is generated by conducting a mixed-integer optimization. Since the evaluation and identification of adequacy are subject to subjective factors, several potentially adequate solutions are generated, which differ in terms of costs, flexibility and changeability. Using post-processing methods, the generated solutions are subsequently processed and transferred to a multi-criteria selection method for evaluating the alternatives.

目前的趋势，如客户对个别产品的需求和较短的产品生命周期，是由公司通过更多种类的产品和变种。然而，关于同步流装配系统的生产线平衡，调整与高投资相关联，这需要用于装配线平衡的新方法。现有的方法不考虑重新分配的工作操作或尺寸的系统固有的灵活性和可变性，根据要求。此外，他们忽视了未来市场形势的不确定性。拟议项目的目的是同步流装配系统的生产线平衡的方法，考虑到潜在的需要，以适应这种不确定的规划环境。为此，重点讨论了发生成本的交换以及系统的灵活性和可变性。基于方案，未来可能的组合物的变体组合进行了研究，并得出所产生的影响的装配系统。在所提出的规划方法中，通过进行混合整数优化来生成足够的自适应装配线平衡。由于充分性的评价和确定受到主观因素的影响，因此产生了几种可能充分的解决方案，这些解决方案在成本、灵活性和可变性方面有所不同。使用后处理方法，生成的解决方案随后进行处理，并转移到一个多标准的选择方法来评估的替代品。
