Purpose: This study investigates the impact of unplanned and planned downtimes on PR (Production Reliability) performance in the tobacco industry, focusing on a company facing challenges due to COVID-19. Methodology/approach: A mixed-method approach is employed, combining quantitative data analysis of production lines (Q1 2024) with qualitative interviews. Root cause analysis (Current Reality Tree) and prioritization (Analytical Hierarchy Process) are used to identify and evaluate solutions. Results/findings: The research reveals maintenance focus on critical parts only and untested new materials as key contributors to low PR. Limitations: The study focuses on one company during a specific timeframe. Contribution: This research proposes a framework for improving PR by recommending a comprehensive maintenance plan, thorough material testing, and an implementation plan based on the PDCA cycle. This is expected to lead to enhanced PR, reduced downtimes, and improved operational efficiency.
