A ROBUST OPTIMIZATION MODEL FOR WORKFORCE CAPACITY PLANNING PROBLEM WITH TURNOVER IN EXPRESS COMPANIES

摘要

Workforce capacity planning to deal with high turnover rate is critical and essential for express companies in China. This paper sets up a robust model to plan the work force capacity so as to reduce the turnover and maintain the stability of operations. The advantage of the model is that it immunizes against the effect of uncertain turnover rates and reflects the employees of different types including promotion, transfer, leave and practice among different positions. Meanwhile, the model with the objective of maximization of couriers’ salary is helpful to reduce the number of voluntarily leaving employees. Then, an empirical analysis of a business department of SF express company is carried out to validate the robust model.
