Abstract

Abstract: A method of designing operation process was worked out for improving safety in material handling operation at seaports with consideration of human's unsafe behaviors. Unsafe behaviors of operators were analyzed with the fuzzy fault tree method and the Bayesian network method to identify the reasons for the unsafe behaviors. A mathematical model, aiming at minimizing the probability of accidents and satisfying the working time constraint condition, was built for optimizing design of operation process. After this, an actual case based on the operation on a port in northern China was illustrated. The results show that the method can enhance the process safety by reducing about 30% occurrence probability of the top event under the condition that just top 7 unsafe behaviors were considered.

Key words: operation process, design method, Bayesian network (BN), fault tree, unsafe behavior, fuzzy number
