The successful design of complex cooperative planning process on daily dispatching plan allows multi dispatchers in railway bureaus to cooperatively make daily dispatching plans. This is helpful to improve the accuracy of daily dispatching plan and further to improve the overall efficiency of railway transportation in China. And building the cooperative planning process is also important for the configuration of the transporting dispatching management information system (TDMS 4.0) used in railway bureaus in China. However, designing such a process is very difficult, considering the complexity of the process. In this paper, a new design method based on roles, activities and time sequences is provided. Finally, the new cooperative planning process is constructed by re-arranging the time sequences relationships among roles, activities in the current process.Keywords -the relation of roles, activities and time sequences" complex cooperative planning processes, daily dispatching plans, railway bureaus.
