Abstract:In today's high-tech manufacturing landscape, increasingly complex and customised products are being made. OEMs often outsource the production of (parts of) their designs to contract manufacturers. These contract manufacturers are specialised in transforming an elaborate set of product specifications into a number of physical products, which requires machines and operators to work with extreme precision and within a narrow window of operation parameters. Because of the ambitious targets set by their clients, the high cost of poor quality and the relatively small production series, it is important for contract manufacturers to mature production processes as efficiently and quickly as possible in order to maintain their competitive position. Effective tracing and management of measurement data generated before, during and after the production activities is a fundamental prerequisite for acquiring insights to improve product and process designs. This study proposes a method for improving the traceability of information generated in high-mix, low-volume, high-precision and high-complexity contract manufacturing environments. After identifying the most significant conditions for achieving adequate information traceability, a framework of interlinking information contents is proposed. Furthermore, the research dives deeper into the necessary architecture of various IT systems in order to support this framework. A case study at NTS Norma Hengelo, a contract manufacturer that fits the described profile, is performed to validate the proposed information traceability method and supporting IT architecture.
