项目摘要

Within the factory planning process, the technical and social elements of a factory as well as their relations are defined. For example, the material- and information-flows are influenced by the selected production control system and the procurement concept. Due to the fact, that the factory structure is exposed to several influencing factors, its structure elements and their relations among each other are affected continuously and thus have to be adapted accordingly. By just using descriptive process models, these adaptions cannot be implemented according to modern requirements.Existing approaches only include a rough description of the factory structure and neglect the effects of possible changes for established factory structures. The proposed research project is going to deal with the question, in which way and how strong changes in the factory environment influence the factory structure in terms of its elements and their relations. Furthermore a method, which enables the anticipation of resulting and necessary structural adaptions of the factory structure is going to be elaborated within this project. In a first step, a description model for the factory structure is going to be developed. In addition to that, possible adaptions are evaluated and documented. In a second step, a functional model, detailing the relations among all factory elements and describing their effects on each other is going to be designed. Using this functional model, necessary adaptions can be detected and executed following a predefined process.By the use of the model, necessary structural adjustments cannot only be identified but also transferred into measures and implemented in the factory. The adjustment of the affected elements is methodically supported. The quality dependence of the planer experience is reduced. Potential blockages, which lead to decelerations during the ramp-up of a factory after a restructuring process and by this to sales shortfalls or extensive error adjustment costs can be avoided or at least reduced. The transparency also allows the deduction of effective and efficient measures for the restructuring process, which will lower the amount of wasted resources in the company.

在工厂规划过程中，工厂的技术和社会要素以及它们之间的关系被定义。例如，物料流和信息流受到所选择的生产控制系统和采购概念的影响。由于工厂结构受到多种影响因素的影响，其结构要素及其相互之间的关系不断受到影响，因此必须进行相应的调整。通过仅仅使用描述性流程模型，这些调整不能根据现代需求来实现。现有的方法只包括对工厂结构的粗略描述，而忽略了对现有工厂结构可能发生的变化的影响。所提议的研究项目将会处理这样一个问题，即工厂环境的变化以何种方式以及有多强烈地影响工厂结构的要素及其关系。此外，该项目还将详细阐述一种方法，该方法能够预测工厂结构的结果和必要的结构调整。在第一步中，将开发工厂结构的描述模型。除此之外，还要评估和记录可能的调整。在第二步中，将设计一个功能模型，详细描述所有工厂元素之间的关系，并描述它们彼此之间的影响。使用此功能模型，可以按照预定义的流程检测和执行必要的调整。通过使用该模型，不仅可以识别必要的结构调整，而且可以转化为措施并在工厂中实施。系统地支持对受影响元素的调整。刨工经验的质量依赖性降低了。可以避免或至少减少潜在的阻塞，这些阻塞会导致工厂在重组过程后的加速过程中减速，从而导致销售不足或广泛的错误调整成本。透明度还允许扣除重组过程中有效和高效的措施，这将减少公司浪费的资源数量。
