Ship Security Information Integration And Comprehensive Decision-Making System Design And Implementation

Thanks to the unceasing advancement of science and technology,the information construction of maintenance management of electromechanical equipment for ships has delightful phase achievements.In the three-level maintenance guarantee system of selfrepair,aviation repair and factory repair,shipping enterprises set about studying how to efficiently address the issues of which level and where to repair the faulty parts,how to cut down the maintenance cost and how to shorten the maintenance time on the strength of computer technology.Although there are an increasing number of means for shipping enterprises to collect and gather data information by relying on ship management system,maintenance management system and other systems,the database scale of all sorts of information systems is expanding day by day,and the complexity is on the rise as well.However,the traditional database technology can not offer data support for the integration analysis of data and comprehensive decision-making,and it is hard to satisfy the requirements of decision makers for multi-angle data analysis.The ship security information integration and comprehensive decision-making system(hereinafter referred to as decisionmaking system)integrates the data of each separated related functional system into a unified system by virtue of big data technology,in a bid to fulfill comprehensive decision-making of maintenance level of electromechanical equipment of ships.Primarily,this thesis fully learns about the three-level maintenance security system,maintenance management workflow and existing subsystems of shipping enterprises,investigates the functional requirements of maintenance managers and maintenance personnel of shipping enterprises,and designs a decision-making system premised on B/S architecture through demand analysis.By building automatic data capture interface and manual data entry interface,the system selects HBase as comprehensive database to realize information integration,and sets up data service interface,in a bid to facilitate each business subsystem to access the comprehensive database;by building a simulation data source covering the data characteristics of existing business systems,it is intended to achieve the data simulation of each business system,and finally offer data support for comprehensive decision-making of maintenance level.Guided by the three-level maintenance security system of shipping enterprises,the economic decision-making model based on minimum cost flow,the non-economic decision-making model taking into account time and the comprehensive decision-making analysis model based on combination algorithm are used and implemented for the decision-making system.By analyzing the integrated data,the researcher conducts a comprehensive analysis of the maintenance level of electromechanical equipment,and works out the decision-making report of maintenance level for maintenance managers in light of the decision-making results.Furthermore,the researcher develops the decision-making system by means of JAVA programming language,Spring Boot and other frames,and verifies the data integration and access function through the system interface.Upon completion of the decision-making system,with a view to test the functions of the system,this thesis tests the functions of service node,cluster deployment and fault-tolerant policy configuration in 100-megabit LAN by using 2 computers to run 6 virtual machines to simulate 1 client and 5 servers as the test environment.After the decision-making system passes the test,the project acceptance work will be finished,and the system is put into use in the actual maintenance management activities of shipping enterprises.Based on the actual operation of the system,the decision-making system can cooperate with the decision-makers,help shipping enterprises cut down maintenance costs,enhance quality control capability,and lay a solid foundation for the informationization,networking and standardization of electromechanical equipment for ships,in a more efficient manner and conform to the requirements for the maintenance and information integration of modern shipping enterprises.
