Maintenance Planning

Maintenance planning services in the supply chain

Maintenance Planning

Maintenance planning begins early in the acquisition process with development of the maintenance concept and the anticipation of maintenance needs. It is conducted to evolve and establish requirements and tasks to be accomplished for achieving, restoring, and maintaining the operational capability for the life of the system.

Define the actions and support necessary to ensure that the system attains the specified system readiness objectives with minimum Life Cycle Cost (LCC)
Set up specific criteria for repair, including Built-In Test Equipment (BITE) requirements, testability, reliability, and maintainability; support equipment requirements; automatic test equipment; and manpower skills and facility requirements
State specific maintenance tasks, to be performed on the system
Define actions and support required for fielding and marketing the system
Address warranty considerations

The maintenance concept must ensure prudent use of manpower and resources. When formulating the maintenance concept, analysis of the proposed work environment on the health and safety of maintenance personnel must be considered.

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 discard, maintenance task distribution, support equipment and ATE, and manpower and personnel requirements.

 For 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 correctly.

"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 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 links with

Functional analysis Storage
Specification requirements Spare parts
Information delivery Operations research
Manufacture / quality Human factors
Maintenance Technical documentation
Transport Work skills training

Effective reliability engineering requires experience, broad engineering skills and knowledge from many different fields of engineering.

Reliability engineering focuses on costs of failure caused by system downtime, cost of spares, repair equipment, personnel and cost of warranty claims.
