Research On Maritime Safety Information Broadcast Benefit Assessment Methods

In recent years, the growing number of ships at sea trips are increasing, with ship communication system upgrades and ship update conditions change, maritime safety information broadcast mode has also undergone changes. These factors will generate a certain extent, the impact of maritime safety information broadcast effective, thus using the scientific method is correct and reasonable evaluation of this effect, as well as an accurate assessment of advertisement effectiveness under various conditions, future planning and design process for maritime security important reference. Of maritime safety information watching ratio is the maritime information center target information covering the waters, in a certain period of time, at least a way to watching the ships of the Maritime Safety Information trips all the stops in the period, the ratio of trips through the target area of the ship. Some watching ratio of the broadcast business refers to a period of time, to listen to the ships of maritime safety information in the way of vessels docked within the period, the ratio of ship voyages through goals waters. Maritime safety information broadcast effectiveness research ship watching ratio as an important reference for the relevant departments to provide a basis for decision making.The main goal of this project is to study maritime safety information broadcast effective, the type of start of maritime safety information broadcast from coast stations, based on the port environmental factors such as ship security analysis, summarized the law of demand summarizes information. Coast stations radio broadcast information covering the passage through maritime space ship total number questionnaire basic data collection, classification statistical analysis based on the data collected, and then build a statistical model to draw watching ratio, and finally re-establish The prediction model watching ratio forecast. This paper from the collection of the data, the data start to obtain basic information as well as data, scientific data analysis of the collected data and other information, calculated by reference to the television ratings developed ship watching ratio ship questionnaire information through statistical records, the use of statistics Principles of statistics over the years the ship watching ratio coast stations, developed the statistical model will cover the various types of vessels within the waters watching ratio out. Quarterly historical data according to the statistics, linear regression algorithm developed prediction model to forecast the ship in the next year watching ratio, and verify the correctness of the statistics and forecast results. The appropriate choice of programming language, database and development platform, sampling models, statistical models and predictive models, and other auxiliary functions in the software platform to achieve its function.To achieve these objectives, the integrated design and realize a set of sampling survey, statistical models, predictive models, and a variety of additional features as one of the maritime safety information broadcast effective evaluation system, with a strong practical value and a testing the system.
