The Path from Data to Actionable Information as a Driver for the Industrial Ecosystem
Prescriptive analytics is often referred to as wisdom because they transition the analytical process from reactive to proactive and allow systems to make judgments based on historical evidence and learning . When prescriptive AI models are utilized at the enrichment stage of analysis , they can create self-aware , self-organizing equipment that can dynamically orchestrate to perform complex tasks without involving the ecosystem ; the ecosystem , in this case , is providing high-level business requirements .
CASE STUDIES used to improve processes and equipment use . The Association for Manufacturing Technology ( AMT ), the trade association for the machine tool builders , set out to define how OEE was to be computed for their membership , specifying that OEE is to be used as a benchmarking and continuous improvement metric , not as a way to compare machines from different builders .
AMT published the standard methodology to calculate OEE for discrete manufacturing in the Production Equipment Availability report ( now at edition 4 ) in 2011 20 . They define OEE as follows :
OVERALL EQUIPMENT EFFECTIVENESS ( OEE ) – HOW TO MAKE IT A VALUABLE KPI USING TRUEOEE™
OEE is one of the most common key performance indicators ( KPI ) manufactures
OEE = Overall Availability × Performance Efficiency × Quality × 100 [ 1 ] Where the terms are defined as follows :
Overall Availabilty =
Performance Efficiency =
Quality =
Production Time
Scheduled Operating Time Planned Process Time Actual Process Time
Good Parts Introduced Parts
Measured Output or
Target Output
