About The Customer
A global manufacturer
The Challenge

The company’s polymer mixing process was producing output of inconsistent quality, with yields sometimes dipping as low as 50% or 60%. The scrapping of poor batches created huge costs and was crippling production capacity. The root cause was traced to ever-changing product specifications, in addition to variations in a range of production parameters. Production engineers were unable to stabilize the process using traditional approaches as mixing polymer was stubbornly unstable and each new product formulation only exacerbated the problem. To solve this issue, this global manufacturer needed a solution that provided the following capabilities: • Ingest and integrate Internet of Things (IoT) data from machinery, sensors, the environment and other sources • Discover the critical factors and optimal process parameters through correlation, visual analysis, and optimization algorithms • Provide deep process insight, enabling daily decision support and continuous improvement • Dynamically and continuously optimize the process through machine learning

The Solution

Hitachi delivered an advanced analytics platform that integrated a wide range of production data and sensor data outputs to visualize, analyze, and diagnose the mixing process. This new insight enabled the production engineering team to understand the correlations and cause-and-effect from a wide number of variables. By adding machine-learning functionality, the solution was able to make continuous process adjustments to improve the yield over a period of several months.
