Manufacturing has been rejuvenated by automation and digitalization. This has brought forth the new industrial era also called Industry 4.0. During the last few years, we have collaborated with companies from various industries that have all been going through this transformation. Through these collaborations, we have collected numerous examples of (sometimes troublesome) experiences with Big Data applications of production analytics. These experiences reflect the current state of production data and the challenges it poses. Our goal in this paper is to share those experiences and lessons learned in dealing with practical issues from data acquisition to data management and finally to data analytics.

自动化和数字化使制造业焕发了青春。这带来了也称为工业4.0的新工业时代。在过去的几年中，我们与各个行业的公司进行了合作，这些公司都在经历着这种转型。通过这些合作，我们收集了许多生产分析大数据应用程序（有时很麻烦）的示例。这些经验反映了生产数据的当前状态及其带来的挑战。我们在本文中的目标是分享在处理从数据采集到数据管理到最终到数据分析的实际问题中的经验和教训。
