Abstract

In this research, it has been tried to optimize the efficiency of employees by considering the concept of human factor engineering in scheduling. Due to the importance of human parameters such as learning and forgetting in employees' skills, especially during job rotation, these factors have been studied and modeled in the issue of staff job rotation scheduling. For this purpose, a nonlinear integer programming model is proposed for scheduling problem of employees with two types of skills. The objective function of the model is to maximize the employee performance. Different examples are solved by considering different parameters to analyze the effects of staff costs, learning and forgetting on staff scheduling efficiency. To solve this problem, GAMZ software is used. The results showed that the proposed model has the ability to provide employee scheduling plans with the aim of maximizing employees. The computational results also indicated that learning and forgetting rate play an important role in determining the optimal scheduling plan and the use or non-use of semi-skilled workers and the movement of employees between machines. The proposed model and the results of this research help employers in using a variety of scheduling schemes and system optimization with dual constraints.
