摘要

本研究的目的是证实粮食收获机服务恢复的信息动态管理模型。实际结果将形成智能技术工程管理,确保联合收割机的效率。研究方法。这项工作的方法论基础是对复杂技术系统,特别是联合收割机服务回收管理的信息和动态模型的已知科学结果进行概括和分析,并使用系统方法。采用分析法和比较分析法,形成科学问题,确定研究目的,设定研究目标。系统工程理论、系统分析方法论和图论研究的主要规定被用于经验模型的创建。研究结果。本文将具有统计可靠性的数据视为单峰数据,并根据Pearson准则符合随机变量的一个已知分布定律。在形成一组受控的单峰参数后,对其相互影响进行分析,以实现以下目标:检查所选参数的独立性,识别参数之间的模式,确定模型参数的使用顺序。从联合收割机技术准备系数损失的计算数据可以看出,40.3%的技术准备系数的损失是由于等待联合收割机维护和维修以及等待送去恢复联合收割机的停机时间造成的,维护和维修技术准备系数为32.5%。所有类型的维护和维修的准备就绪系数损失最大的是第二次维护次数9.5%,由于所研究的联合收割机可靠性低,计划外维修以及计划外维修和等待装运的预期损失占技术准备就绪损失的25.2%。结论。通过所进行的研究,获得了新的科学依据的技术决策和发展,这些决策和发展旨在提高农业企业联合收割机工作能力的恢复生产过程的运行效率。通过对研究对象和生产过程组织中的世界经验的分析,确定了应作为所提出模型一部分的基本功能子系统。组织监测联合收割机的操作和技术状况:收集有关联合收割机操作、联合收割机操作模式和车载智能开关单元技术状况的信息,以及(在缺乏信息的情况下)从在役的固定式和便携式自动技术诊断系统中收集信息。所提出的联合收割机服务恢复管理信息动态模型的结构与现代创新方法有着显著的区别,即侧重于实施智能技术工程管理,以确保联合收割机的效率。关键词:恢复,技术准备系数,联合收割机,可靠性,效率,维修。
