•Develops a DRC system with human factors (HFs) and product quality.•HFs are: learning, forgetting, fatigue and recovery.•System performance is a twofold cost function.•Worker flexibility, transfer policy, and workstation configuration affect performance.
This paper studies the effects of some human characteristics on production planning in a Dual-Resource Constrained (DRC) system and the quality of products. Human behavior is captured by the learning–forgetting–fatigue–recovery model (LFFRM). The production process is modeled through a Quality Learning Curve (QLC) model while the quality deficits are the result of human error and machine malfunction. The system performance is presented with a twofold cost function considering direct (time) and indirect (quality) costs. The results indicate that the system performance is concave over a production run, which represents the optimum flexibility level, transfer policy, and the workstation configuration.
