摘　　要：在航天装备在役考核试验执行中,对于存在时空重叠的多个任务以及子任务,需要应用并行执行支撑技术,从而完善任务分配的合理性、提高任务处理的效率、数据处理的实时性等约束性质;以典型航天装备在役考核综合评估任务为对象,从任务流层面和数据流层面,对并行控制与处理算法进行研究,采用基于预留缓存的多线程并行并发技术,对多任务进行并行处理和执行;实现任务的合理自主规划、数据处理与读写的多线程触发与执行;依托自主研发的航天装备在役考核综合评估系统,对方法进行验证;系统运行结果表明,采用基于预留缓存的并发访问及多任务并行支撑技术可以高效、快速地对大纲设计、数据采集等多个过程进行并发执行控制,对多源数据进行并行处理计算,有效提高了在役考核试验执行和综合评估的效率。Multi-Task Concurrent Execution Technology(MTCET)is applied to support time-space-overlapped tasks and subtasks of analysis and evaluation for In-Service Inspection(ISI)of Space Equipment,which is able to improve the rationality of task assignment,efficiency of task execution and instantaneity of data process.Concurrent technology based on Multi-thread and reserving cache is adapted to execute multi-task in the aspects of both task flow and data flow of overall assessment of Space Equipment.The method is verified based on the self-developed Overall Evaluating System of Space Equipment,whose result shows that several processes such as outline design and data collection can be concurrently executed and controlled effectively by applying presented multi-task concurrent execution technology,and multi-source data can be processed and calculated concurrently,which lifts the efficiency of in-service inspection test and overall evaluation.
