Operator fatigue and productivity

By Dr. Alin Posteucă

As is well known, productivity is also closely linked to the operator, equipment, and/ or line time cycle. Over time, significant time cycle variations (standard cycle time vs. real cycle time) result in amplification of the non-synchronization of the flow precesses (work centers) and, implicitly, a disturbance to the standardization of the minimum and maximum stock levels, the increase of the lead time, overtime, quipment problems and especially non-compliance in the takt time. In this context, situations of overworking of people, equipment, and storage spaces often occur creating waste along the entire production stream and beyond.
