复杂产品维修构型变更管控方法

Maintenance configuration change management methods for complex product

针对复杂产品维修数据变更频次低、影响范围大和记录准确性要求高的问题,提出利用基线方法管理多次维修中构型变更的连续性,利用过程分析方法阐释单次维修过程中数据变更内容和方向,并利用IDEF0方法将维修业务分解到具体作业上,建立作业层面的维修数据变更模型。最后,以多次维修中动车组转向架轮对组成变更为例,说明在维修作业驱动下修前基线如何变更生成修后基线,形成履历信息和更新实例维修构型。所提出的构型变更管控方法兼顾了单次维修构型变更的准确性和多次维修构型变更的连续性,为实现维修数据自动化变更提供了理论和方法基础。

For complex product maintenance data change in a low frequency with a wide range effect and high accuracy requirements,the baseline method was proposed to manage the change continuity of configuration data in multiple maintenance events,and the process analysis approach was put forward to explain the content and direction of the data changes in the single maintenance process,and the IDEF0 method was used to decompose maintenance business to specific tasks for establishing a maintenance data change model at the operation level.Taking the change of wheel set composition during multiple maintenance events as an example,how to change the baseline before maintenance to generate the baseline after maintenance was explained,the maintenance record information was formed and the instance maintenance configuration was updated under the driving of maintenance operations.The proposed configuration change control method both considered the accuracy of a single maintenance configuration change and the continuity of multiple maintenance configuration changes,which provided a theoretical and methodological basis for automatic maintenance data change.
