Simulating the effect of workers' mood on the productivity of assembly lines

Production lines have various components, from workers to loads and machines, each of which can influence the productivity of the entire system either directly or indirectly. One of the most vulnerable parts of an assembly line is the human element. Studies have been conducted on the methods to improve assembly line productivity, both from a worker's ergonomic perspective and from a system simulation perspective, but neither approach has considered the worker's mood. This study uses systems simulation capabilities to address some of the major psychological difficulties that may affect worker efficiency beyond the ergonomic conditions, such as emotional and cognitive factors. This study aims to present feasible solutions for increasing the productivity of an assembly line in a backpack company in Montana, with regard to an employee's mood, and cognitive and physical states.
