一种航天侦察任务-资源匹配的负载均衡方法
A Load Balancing Method for Matching Reconnaissance Tasks and Satellite Resources
摘要
Abstract
In current space-based reconnaissance task pretreatment process, resource allocation generally lies on task requimnents,which may lead to load imbalance. In light of this, a matching method that considers both task requirements and resource load was preseted. Fof the sake of load balancing, the key task elements and their description method were analyzed. Based on the task flow model, formula and algorithm for calculating the probability of the executed task were available, then the execuaion probability were used to measure the load status of satellite resources. Finally, the research put forward a load balancing model and a corresponding heuristic algorithm for matching reconnaissance tasks and satellite resources, which takes into consideration the workload, priority, quality of tasks and execution probability. Simulation results show that the proposed load balancing method can effectively improve the utilization of satellite resources and reconnaissance benefit.关键词
