Research And Implementation Of A SAAS-based Aircraft Defect Management System

In the process of airlines operation,aircraft maintenance management information system as directly related to the aircraft flight safety and maintenance cost,applied more and more widely attention and research.With the rapid development of digital communication technology and computer and aviation market competition intensifying,maintenance management information system has developed to a new stage of the application,and now to get further development in the civil aviation enterprise.The aircraft defect management system as a subsystem of maintenance management information system,the purpose is to assist aircraft maintenance worker to complete the aircraft defect monitoring and defect deferring,etc.Based on SaaS(Software as a Service)model aircraft defect management system with the development of the computer cloud technology,not only can reduce the threshold of the aviation enterprise into the system,but also can improve the work efficiency,so as to provide a powerful guarantee to protect the safety of flight.Firstly,the article expatiates the background of the aircraft defect management system,analysis of the present reality airlines aircraft maintenance work ma nagement and problems,and according to the characteristics of the aircraft defect management,combining with the SaaS model,put forward a design of aircraft defect management system based on SaaS.In the process of software design,take ensure flight safety and improve work efficiency as the aircraft defect management system design goal,in accordance with the requirements of the software design for aircraft defect management system demand analysis and detailed design of main function module.Adopt the method of UML for system analysis,and further to determine the system functional requirements,non-functional requirements,hierarchical structure,andother requirements.Through analyzing each layer architecture in detail respectively,using Spring,DAO and other technology,implementation of the system architecture design.By designing the database table to complete system multi-tenancy,extensibility and the demand of the configurability,and design the system data security,make the design of aircraft defect information management system can meet the needs of the maintenance enterprise actual work.Then,the article expounds the implementation of themulti-tenant data isolation code and using the sequence diagram for data security,takes flight log book input and deferred defect management as an example,elaborates the implementation details of the system by using activity diagram.Finally,this article introduces the functionality and performance testing.From the operation of the aircraft defect management system,it is basically achieved the design goals,meets the need of the aircraft defect management,completes the aircraft defect monitoring and defect deferring by the network,eliminates the phenomenon of information independent with each other.Through the use of the system,effectively achieve the goal of maintenance defect management,promote the development of aircraft maintenance enterprise's informatization.In the future,using the cross-platform features of HTML5 on the mobile devices(mobile phone?iPad)support the design of the project,to provide service for the maintenance of the network in real time.
