Sigmafine Virtual Summit 2020

This presentation shows Codelco’s journey in adopting Sigmafine as its corporate metallurgical balance system, the difficulties faced, the benefits obtained, the actual state of the overall implementation, as well as the challenges for the coming years.

At the Billings refinery, Sigmafine is used to facilitate communication and drive data-informed decisions across the organization.   Accounting for timely and accurate inventory and production numbers involves taking disparate Data inputs from multiple sources and departments.  This information then needs to be conditioned in a manner that can provide a meaningful and accurate dataset to the data consumers.  The information needs to be timely, accurate, verifiable, and consistent with P66 business processes.  This presentation will discuss how Sigmafine is used to achieve this and the benefits derived.

A look inside on how Hemlock Semiconductor uses Sigmafine for day to day production of highly pure polysilicon for the electronic and solar power industry

We will review the basic validation checks for missing data (I/O timeout), flat-line data (sensor malfunction), out-of-range data etc., and issues in source instrumentation/control system, network connectivity, faulty data collection configuration (scan rate, unit-of-measure, exception/compression specs) etc.  We will also cover advanced analytics, including machine learning and data reconciliation with illustrative use cases.
