| Abstract: | The broadcast business of maritime safety information has always occupied an important position in the shipping industry. Through getting the statistics of receiving security information in the radio coverage area, the utilization rate of the the appropriate eal model of the with a practical information resources broadcasted by information center can be learned. It is helpful for the staff to choose way to broadcast maritime security information for more coverage of information. In this paper, a statisti ship watching ratio for maritime safety information based on the statistics theory is proposed and analyzed example, which verifies the reliability and the practical value of the proposed model. |
