LORA considers 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.
Maintenance planning relies on Level Of Repair
Analysis (LORA) as a function of the system acquisition
process. LORA is used in the US Department of Defense (DoD)
as an analytical methodology to determine when an item
will be replaced, repaired, or discarded based on cost
considerations and operational readiness.
Conduct a LORA repair
analysis to optimize the
support system, in terms
of LCC, readiness
objectives, design for
support equipment and
ATE, and manpower and
a complex engineering system containing thousands of assemblies, sub-assemblies,
components, organized into several levels of indenture and with a number of
possible repair decisions, LORA seeks to determine an optimal provision of
repair and maintenance facilities to minimize overall system 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
"Reliability is, after all, engineering in its most practical
form." stated by James R. Schlesinger, Former US
Secretary of State for Defense.
Reliability is defined as the probability of failure, the frequency of
failures or, in terms of availability, a probability
derived from reliability and maintainability. Maintainability and maintenance
may be defined as a part of reliability engineering.
Reliability plays a key role in cost-effectiveness of systems.
Reliability engineering is an engineering field that
deals with the study, evaluation, and life-cycle support
of a system or component to perform under stated
conditions for a specified period of time.
Reliability engineering for complex systems requires a
different, more elaborate systems approach than for
non-complex systems. Reliability analysis has important
||Manufacture / quality
||Work skills training
Effective reliability engineering requires experience,
broad engineering skills and knowledge from many
different fields of engineering.
engineering focuses on costs of failure caused by system downtime, cost of
spares, repair equipment, personnel and cost of warranty claims.
