Continuous inspection planning methodology for quality inspection during product development process

检验计划被定义为考虑技术、组织和经济问题的质量检验计划[VDI85，第2条；DIN08，第7条]。质量检查提供关于单个部件在多大程度上符合各自提供的预定义要求的信息[VDI85，S.4]。在研究中，检查计划被分配到生产开始前的工艺计划领域[BERN05，S.14]。它基于产品创建过程中位于检验计划上游的过程和计划活动(如蓝图)的数据。然而，为了有效地计划产品的质量检验，检验规划还依赖于产品创建过程中后续过程的信息集成。这些数据提供了关于生产和现场的当前产品状态(即最终客户使用的产品)的信息。除了考虑生产流程中收集的检验数据(即进行的检验的结果)，以确定必要的检验量外，迄今为止还没有系统和持续地调整基于工序数据的检验计划，这些工序数据是检验计划(例如，客户投诉)之后的数据。由于到目前为止，将后续工序数据整合到检验计划中一直被忽视，KorPus研究项目旨在缩小这一研究差距。这应通过开发能够持续学习的检查计划系统来实现。系统地、持续地将来自后续工序的数据转移到检验计划中，能够使产品的检验计划适应生产和现场的当前情况。这种适应不仅基于对检验数据的分析，还基于消除错误过程、客户投诉过程的数据以及其他提供产品S状态信息的数据。通过不断更新检验计划，可以修改或消除效率低下的检验。另一个基本优势是，检查可以更快地根据现场新出现的错误进行调整。因此，与现状相比，响应时间可以缩短。为了最大限度地减少检查和错误成本的总和，将开发另一种方法，对与更改检查有关的工作和产品缺陷的后果进行经济比较。

Inspection planning is defined as the planning of quality inspections [VDI85, S. 2; DIN08, S.7] taking technical, organizational and economical issues into account. Quality inspections give information on the extent to which a single unit conforms to provided respectively predefined requirements [VDI85, S. 4]. In Research inspection planning is assigned to the field of process planning before production starts [BERN05, S. 14]. It is based on data of processes and planning activities (e.g. blue prints) which are located upstream to inspection planning in the product creation process.However, in order to plan quality inspections of products efficiently inspection planning is also dependent on the integration of information from processes which are subsequent in the product creation process. These data provide information on the current product status in the production and in the field (i.e. product use by the final customer). Except for the consideration of inspection data collected in the production flow (i.e. results of carried out inspections), which is used to determine the necessary amount of inspection, there is so far no systematical and continuous adjustment of the inspection plan based on data from processes, which are subsequent (in terms of the product creation process) to inspection planning (e.g. customer complaints).As the integration of subsequent processes data into inspection planning has been neglected so far the research project KorPus aims to close this research gap. This shall be done by developing an inspection planning system, which is able to learn continuously. A systematical and continuous transfer of the data coming from subsequent processes into inspection planning enables to adapt inspection plans of products to the current situation in the production and in the field. The adaption is not only based on the analysis of inspection data but also on data of error elimination processes, customer complaint processes and other data which provide information on the product s status.By continuously updating the inspection plans inefficient inspections can be revised or rather eliminated. Another essential advantage is that inspections can faster be adjusted to newly occurring errors in the field. Thus, the response time can be reduced in comparison to the status quo. An additional method on an economical comparison between the effort that is related to changing the inspections and the consequences of product defects will be developed in order to minimize the sum of the inspection and the error costs.
