Abstract: In Guangdong-Hong Kong-Macao Greater Bay Area (GBA), labor-intensive enterprises, such as moving companies, are currently facing the historical stage of the labor market’s transition from the old to the new. The emerging young labor force has significantly different satisfaction functions of working hours and income from the previous generation of the labor force. Based on this background, this paper intends to explore how to make factories obtain high profits while ensuring workers’ job satisfaction at a high level. Considering the different characteristics of income-preferred workers and comfort-preferred workers, we combine operations research and the design of utility function that consists of workers’ overtime dissatisfaction and overtime tolerance, to evaluate workers’ job satisfaction quantitatively and formulate a factory employment model. Then we study the relationship between the task volume, employment plans of the factory, workers’ job satisfaction and factory revenues in different scenarios. Simulation results show that if the factory has a high variance of the task volume, the proportion of comfort-preferred workers in the employment plan should be increased, and if there is a high variance in the time of finishing one task, the proportion of income-preferred workers in the employment plan should be increased. The research in this paper has great significance of advancing labors’ employment, maintaining the regional stability and absorbing more enterprises and talents for GBA.

Key words: utility function, job satisfaction, factory employment plans, factory revenues
