Introduction
Manufacturing efficiency in discrete operations depends heavily on accurate data capture, classification, and real-time measurement of performance metrics such as OEE (Overall Equipment Effectiveness). However, inconsistent data capture, manual interventions, and unreliable PLC logic often lead to incorrect insights, masking true efficiency and impacting decision-making. This case study highlights how an AI–IIoT–enabled framework was conceptualized to address these challenges. By improving data accuracy, automating classification, and standardizing implementation across plants, the organization aimed to unlock true production visibility and operational efficiency.
