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，定义了工厂的技术和社会要素以及它们之间的关系。例如，材料流和信息流受到选定的生产控制系统和采购概念的影响。由于工厂结构受到多个影响因素的影响，其结构要素及其相互关系不断受到影响，因此必须进行相应的调整。现有的方法仅对工厂结构进行了粗略的描述，忽略了现有工厂结构可能发生的变化对工厂结构的影响。拟议的研究项目将处理的问题，在何种方式和如何强烈的变化，在工厂环境影响工厂结构的要素和它们之间的关系。此外，该项目还将详细说明一种方法，该方法可以预测工厂结构的最终和必要的结构调整。在第一步中，将开发工厂结构的描述模型。除此之外，还评估并记录了可能的调整。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，并描述它们之间的相互影响。使用该功能模型，可以检测必要的调整并按照预定义的流程执行。通过使用该模型，不仅可以识别必要的结构调整，还可以将其转换为措施并在工厂中实施。对受影响要素的调整得到了系统的支持。刨经验的质量依赖性降低。可以避免或至少减少潜在的堵塞，这些堵塞会导致工厂在重组过程后的爬坡过程中减速，从而导致销售短缺或大量的错误调整成本。透明度还允许为重组过程采取有效和高效的措施，这将降低公司浪费的资源量。
