Planning of dynamic layouts for the field assembly of XXL-products under competing floor space demands

包装机、图书装订机等尺寸较大的产品（所谓的xxl产品）往往在现场组装。运行装配过程所需的区域，如材料缓冲区或装配区域，在装配过程中会改变其位置和大小。在同时装配多个产品的情况下，在布局规划阶段，通常每个产品静态保留的地板空间比实际需要的要多。到目前为止，还缺乏规划方法和指导方针，以规划多种产品共同使用一个共同的地板空间。这种情况阻碍了对瓶颈资源地板空间的有效利用。本研究项目旨在开发一种方法来规划动态布局的现场组装的xxl产品在竞争的地板空间需求。此外，如何设计装配过程和装配区域的结构，以实现高的地面空间利用率的知识是产生。为了实现这一目标，计划开发一种布局规划的分析方法，其中布局中的单个区域在一个公共区域上为多个产品进行动态变化。该方法应包含一个数学优化问题和求解该问题的算法。此外，采用应使用方法分析了优化问题中某些参数的变化对建筑空间利用效率的影响。研究项目应使用的结果是在xxl产品的现场装配中更好地利用瓶颈资源占地面积，从而在降低物流成本的同时实现高物流绩效。特别是在经济繁荣时期，这可能有助于公司产生更高的销售额。

Products with big dimensions such as packaging or book binding machines (so-called XXL-products) are often assembled in a field assembly. Areas needed for running the assembly process such as material buffers or assembly areas change their position and size during the assembly process. In the case of simultaneous assembly of more than one product, in the phase of layout planning often more floor space is reserved statically per product than is actually needed. So far planning methods and guidelines are missing for planning the cooperative use of one common floor space by more than one product. This circumstance prevents an efficient use of the bottleneck resource floor space. This research project aims for the development of a method for planning dynamic layouts for the field assembly of xxl-products under competing floor space demands. Furthermore knowledge on how to design the assembly process and the structure of assembling areas in order to achieve high floor space utilization is to be generated. To achieve this goal, it is planned, to develop an analytical method for the planning of layouts with a dynamic change of the single areas in the layout on one common area for more than one product. The method shall contain a mathematical optimization problem and an algorithm for solving this problem. In addition the method shall be used to analyze the impact of the variation of certain parameters of the optimization problem on the efficiency of floor space usage. The results of the research project shall be used to obtain a better usage of the bottleneck resource floor space in the field assembly of xxl-products and therefore to reduce logistical costs while simultaneously achieving a high logistical performance. Especially in times of an economic boom this may help companies to generate higher sales.
