Team Teachings: Improving Process Operator Competency

Polymer chip manufacturing is a multi-step, large-volume process that makes hundreds of millions of pounds of products annually at a typical plant. Unlike fiber extrusion, which requires the use of multiple units of specialized equipment, chip manufacturing involves fewer machines operated in either continuous or batch modes. Chip manufacturing is often driven by operator decisions,…

Process Data Mining: Partitioning Variance

Manufacturing facilities can be faced with major challenges when it comes to process improvement, largely because practitioners don’t always know enough about the underlying process factors (x’s) are that drive the improvement metric (Y). Practitioners might have a brainstorming session to tap into the collective experience of experts involved in the process, and design experiments…

Effective Brainstorming: Building an Opportunity Matrix

Manufacturing facilities often are faced with major challenges when it comes to large-scale process improvement. Improving yields at a large manufacturing plant – one that produces millions of pounds of product annually – might require modifications for every step in its process: production equipment, maintenance strategies, operational procedures, process control strategies and analytical support strategies,…

Reducing Sampling Costs: Implementing a Variable Sampling Interval Strategy

Most manufacturing processes are controlled by sampling a product at some regular interval. Often, when a process is running normally, this interval is once every shift. It is not too surprising that in today’s economic climate, where cutting cost is of paramount importance, reducing sampling to save money is inviting, especially at large manufacturing facilities,…
