Objective To optimize the constitutions of the rescue process and medical support teams for submarine rescue, so as to provide new method for evaluating the medical service performance. Methods Using the MedModel software, we established the simulation model of rescue process according to the constitution and work flow for submarine rescue and five ways of getting out of the water. The mean waiting time of 5 ways was calculated. Results According to the ways of getting out of water, the mean waiting time of each way were calculated and the allocation of medical resources were optimized, making the total waiting time meeting the need of medical rescue team. Conclusion This paper optimizes the rescue process and constitution of the rescue team, saving the medical resources, reducing the total waiting time of the wounded, and providing a new method for evaluating medical serves.
