Balancing worker and producer benefits in economic production quantity

International Journal of Production Economics, 2025, vol. 283, issue C

Abstract: Worker welfare and operational efficiency are critical components of production systems, yet they are often considered separately in the literature. This paper integrates these two aspects by extending the classical Economic Production Quantity (EPQ) model to account for worker fatigue accumulation and recovery. We use a linear function to model fatigue, estimated using the least squares method, as it provides a practical representation of fatigue pattern. By explicitly incorporating fatigue as a time-varying factor, this study provides a more accurate description of production dynamics, providing practical insights for labour-intensive industries such as manufacturing.
