面向动态MRO活动的SBOM演化研究

Research on SBOM evolution oriented to dynamic MRO activities

摘要:

为了解决静态服务物料清单（Service BOM,SBOM）不能实时反映动态维修、维护和大修（Maintenance,Repair and Overhaul,MRO）服务过程的问题,针对动态MRO业务中不同的管理需求和服务需求,设计了面向产品服务生命周期的SBOM演化模型。通过分析批次产品、单件产品以及单次MRO服务三类管理需求下SBOM结构的差异性,从装配位置、供应商和MRO任务角度,对SBOM的节点和节点间约束进行分类并给出定义,建立不同类型SBOM的演化关系模型。基于MRO服务需求对通用SBOM和实例SBOM节点的变更影响,描述了SBOM在动态服务过程中的两种变更类型以及每种变更类型下的节点状态,构建随时间而变化的SBOM动态演化模型。最后,以某型号机车转向架为例验证了演化模型的可行性,并基于节点追溯目的提出两种MRO服务追溯机制,大大提高了机车MRO服务中动态数据信息的管理和追溯能力。

Abstract:

To solve the problem that the static service bill of material (service BOM, SBOM) cannot reflect the service process of dynamic maintenance, repair and overhaul (Maintenance, Repair and Overhaul, MRO) in real time, a SBOM evolution model in the product service life cycle for different management and service requirements in the dynamic MRO business is designed. By analyzing the difference of SBOM structure under the three management requirements of batch product, single product and single MRO service, from the perspective of assembly location, supplier and MRO tasks, the nodes and constraints of SBOM are classified and defined, and the evolution relationship model of different types of SBOM is established. Based on the influence of MRO service requirements on the changes of general SBOM and instance SBOM nodes, two types of SBOM changes in the dynamic service process and the node states under each type of changes are described, and the dynamic evolution model of SBOM changing with time is constructed. Finally, a locomotive bogie is taken as an example to prove the feasibility of the evolutionary model, and two MRO service traceability mechanisms are proposed according to the node traceability purpose, which greatly improves the management and traceability ability of dynamic data information in locomotive MRO service.
