| With the rapid development of information technology,a variety of resources,including computing,storage,network,application,data and so on,generally show the trend of servitization.In order to meet the requirements of rapid scheduling and capacity reorganization of task system resources in a rapidly changing environment,real-time,dynamic planning and flexible scheduling of these resources,task completion through resource combination and reliability guarantee have become one of the research focuses in the field of intelligent resource planning.Based on the example of civil aircraft anti-hijacking task,a task resource intelligent planning and reliability guarantee system is designed and implemented to meet the dynamic demand for computing,network and application resources in the process of anti-hijacking,and to realize resource combination optimization,dynamic selection,conflict resolution of antihijacking task system resources and resource adaptive processing caused by environmental changes.In order to obtain the above research objectives,the research work of this paper can be mainly listed as follows:1.Analyze and compare the advantages and disadvantages of different service composition methods,describe the concept of the intelligent planning method,semantic service description method,resource servitization technology and reliability assurance technology.2.Propose an adaptive dynamic resource composition model,extending resource domain and resource type to OWL-S resource semantic model,proposing OWL-R+ resource semantic model,which can realize resource registration and management.3.Study the task-oriented intelligent planning,decompose the task through the multi-scheme HTN planning method of the extended scheme library,and generate the solution composed of the sequence of resource types,completing the association between tasks and resources.The resource matching algorithm that introduces priority parameters of task and resource selection is used to select the optimal resource through functional matching and QoS matching.4.In order to guarantee the reliability of resource planning results,this paper extends non-functional parameters,resource conflict resolution,adaptive processing and other methods to guarantee the reliability of resources and resource combination results.5.Design and implement an intelligent planning system of task resources based on the example of anti-hijacking mission of civil aircraft.Give the detailed design and implementation of the system and related experimental analysis through the application of scenarios. |
