Enhancing Operational Performance in Industry 4.0: The Mediating Role of Total Quality Management and Total Productive Maintenance at Zarharan Industrial Complex

Industry 4.0 represents the integration of cyber-physical systems, enabling real-time data exchange and automation, enhancing efficiency and productivity while fostering innovation in manufacturing processes. Its significance lies in optimizing production, minimizing errors, and facilitating adaptive manufacturing, crucial for competitive edge and sustainable growth in modern industries. The objective of this research is to explore the effects of implementing Industry 4.0 on enhancing operational performance through the implementation of Total Quality Management (TQM) and Total Productive Maintenance and Repairs (TPM). The study focuses on Zarharan Industrial Parts Renovation-Optimization Complex employees, employing a simple random sampling method for data collection. The research employed field methods to gather information, utilizing a Likert scale questionnaire as the primary data collection tool. Content validity was used to establish questionnaire consistency, while Cronbach s alpha coefficient and composite reliability index were utilized for reliability assessment. Additionally, construct validity was verified. With regards to investigating the mediating role of comprehensive quality management and TPM and repairs between Industry 4.0 and operational performance, seven hypotheses were formulated.
