Abstract: Performance ranking is the most concerned part of the performance appraisal process, which is also an “active volcano” causing controversy. Therefore, this paper uses the Hasse graph of partial order set method to identify ranking disputes and control ranking risks, so as to improve the sense of organizational justice and employee satisfaction. First, this paper takes the uncertain weight as the starting point, and reconstructs the performance appraisal model using the theory of partial order set method to obtain the Hasse graph of employee performance ranking which can visually show the hierarchical clustering and unrobust ranking of employees. And in addition, this paper discusses the layering methods and properties of Hasse graphs. The results show that the ranking of comparable employees in Hasse graph is stable. For non-comparable employees, performance ranking is unstable. The example analysis shows that the performance appraisal model constructed by partial order set method can help control the risk points in the evaluation ranking and improve the quality of employee performance evaluation.
