The invention discloses a method and a system for generating crane running strategies. The method comprises the following steps: acquiring the running information and the characteristic parameters ofcranes, wherein the running information comprises the information of at least one working task; sequencing the at least one working task according to the running information, so that the information of each two adjacent sequenced working tasks is mutually connected; determining the running time period of each sequenced working task according to the characteristic parameters and the running information; determining the number of running cranes according to the characteristic parameters and the running information; carrying out task allocation on the cranes according to the number of the cranesand the at least one sequenced working task, and determining a first running strategy for each crane; and judging whether the first running strategy for each crane meets predetermined standards or not, and if not, adjusting the working tasks corresponding to the cranes or the running time periods corresponding to the working tasks, and determining a second running strategy for each crane. The method and the system realize intelligent generation for the running strategies, and eliminate objective human errors, thereby guaranteeing crane running accuracy.
