In view of the problems that the timeliness exists in command and control square task coordination for multiple seats, and the complex command and control process are described and coded, regarding the task tree and task Gantt chart as a form from the perspective of time and status ,a multiseats task coordination model based on task sequence is established. A temporal logic scheduling algorithm is presented by the free event driven strategy. The living example simulation shows that the algorithm can reduce the free time by 9% and the execution time by 4.6%. The model and the algorithm can well describe and optimize the collaborative process, and reduce the free time and execution time in multiseats task coordination, and improve operational efficiency.
