Paper Title
Effect of Worker Fatigue on Economicproduction Quantity

Abstract
Due to fatigue accumulation, the performance of a worker declines with time as he/she performs work tasks. As a solution, companies usually allow short rest breaks for workers during the working hours. These rest breaks usually improve worker productivity, reduce work incidents at the workplace, reduce the long-run effects of fatigue on worker health, reduce defect rate, and consequently reduce cost. In this paper, we propose a mathematical model that integtares the worker fatigue level with the classical economic production quantity.
