Abstract: Under the condition that the proportion of position rank promotion and dismissal is stable, study on enterprise position rank structure change is conducted. A homogeneous Markov chain model is established for this problem. For ideal position rank structure, this problem can be converted into a set of linear equations. With this model, then to optimize the enterprise position rank structure is to dynamically regulate the recruitment rate of every position rank for every year. With the position rank structure data from a large information technology (IT) enterprise, empirical analysis is conducted to verify the effectiveness of the proposed method.

Key words: Markov chain, position rank structure of enterprise, dynamic regulation
