Level of repair analysis

In logistics support planning, Level of repair analysis (LORA) is a prescribed procedure used to determine optimal repair and maintenance policies for complex engineering systems. For systems containing large numbers of assemblies, subassemblies, and components organized into multiple levels of indenture and subject to multiple repair decisions, LORA seeks to determine an optimal provision of repair and maintenance facilities so as to minimize overall life-cycle costs.

Logistics personnel examine not only the cost of the part to be replaced or repaired but all of the elements required to make sure the job is done correctly. This includes the skill level of personnel, support equipment required to perform the task, test equipment required to test the repaired product, and the facilities required to house the entire operation.
