Match the 'golden'batch

摘要

MANY DIFFERENT METRICS OR KEY PERFORMANCE indicators(KPIs)can be used to measure the effectiveness of batch production.These include: batch cycle times;actual results versus expectations;capacity utilization;batch exceptions;conformance to schedule;and attainment to standard [1,2].Some of these are very general categories - an item like "attainment" can include various criteria,such as critical process-measurement trends,laboratory results for a recipe,and product and labor costs,with the standard defined by an exceptional or "gold" batch.
