Abstract Declining birthrate, aging population, and outflow of young people have caused industrial labor shortages, which have been a longstanding issue in Tottori Prefecture, Japan. Increasing the number of personnel in small- and medium-sized enterprises (SMEs) in rural cities such as Tottori Prefecture is difficult; SMEs should focus on improving labor productivity using their existing personnel and equipment. However, SMEs often conduct their operations based on habits and experience and a scientific optimization method to quantitatively evaluate them is needed. In this study, the quality verification of electronic products was treated as a queuing model, and a queuing simulation was performed using event-driven programming to support decision-making on appropriate personnel arrangement in the manufacturing industry. The data on the detection and correction times of each fault in quality verification were used for simulation. Moreover, the upper limit of the number of faults that could be simultaneously corrected were changed, and interrupt processing by considering the impact of faults on the product was implemented. The simulation results were visualized to clarify the queue length, occurrence time, and waiting time for the queue constituted by faults waiting to be corrected.
