how to do a level of repair analysis

What is level of repair analysis?

Level of repair analysis is a method for finding the right level and amount of maintenance you invest in an asset, so you have the smallest possible life cycle costs. It's how you decide if you need to repair or replace things, and when you do repairs, where you do them.

What is Lora (level of repair analysis)?

What is O level and I level maintenance?

These levels are essentially where repair work is performed: Organizational level (O-level), which is performed on the asset on site. Intermediate level (I-level), which is performed in dedicated maintenance areas or backshops. Depot level (D-level), which is performed off site, such as at an OEM factory.

What is repair cycle analysis?

Repair cycle refers to the stages through which a repairable item passes from the time of its removal or replacement until it is reinstalled or placed in stock in a serviceable condition. Definition (2): “From the perspective of logistics, a model of the life cycle of parts in a supply chain can be developed.

What is maintenance task analysis?

What is level of repair analysis (LORA)?

Level of repair analysis is a method for finding the right level and amount of maintenance you invest in an asset, so you have the smallest possible life cycle costs. It's how you decide if you need to repair or replace things, and when you do repairs, where you do them.

What do you include in LORA calculations?

When it fails, you have several different maintenance options, and to find the best one, you need to build different cost models.

What is a level of repair analysis?

The Level of Repair Analysis (LORA) can be performed as either a non-economic or an economic analysis. The non-economic LORA is performed to assess and influence design from a Supportability standpoint and typically occurs in the Technology Maturation and Risk Reduction (TMRR) phase of the Life Cycle Management Framework. The economic LORA is performed to identify the most economic repair alternative for components and typically occurs in the Engineering & Manufacturing Development phase of the Life Cycle Management Framework.

What is reliability measured as?

Reliability, measured as Mean Time between Failures (MTBF)

What is the Better Buying Power Guidance?

The Better Buying Power Guidance requires programs to establish an affordability target . This target is not only acquisition costs, but also must include operation and support cost in the affordability calculation. The LORA calculates Total Maintenance Policy Cost and includes repair costs, sparing, holding, transportation, requisition and cataloging. Although it does not comprise all Operation and Support costs, LORA modeling efforts represent a verifiable and repeatable estimate that is needed in the affordability calculation of Better Buying Power and Affordability.

What is technical performance?

Technical Performance, which is comprised of Functions and Capabilities from the Capability Development Document (CDD) requirements

Why is I level maintenance important?

Because it is more specialized , I-level maintenance allows for more thorough and time-consuming diagnostic testing and repair procedures, usually in support of failed items removed at the organizational level of repair. Test equipment is more common at this level of repair, and is used to automate many test procedures. Spare parts maintained at this level of repair are known as bench stock .

Where does D level maintenance occur?

Depot, or D-level maintenance typically occurs in highly specialized repair depots, or at original equipment manufacturer (OEM) facilities. These sites are typically not at operating locations, and extensive diagnostic equipment and possibly even manufacturing capabilities exist.

What is Lora analysis?

LORA establishes when and where each unit will be repaired and determines if it is more cost effective to discard an item than attempt to repair it. While this kind of analysis seems costly and unnecessary, at enterprise scales over many years, significant cost savings can be realized.

What is the purpose of evaluating alternative economic models?

Evaluate alternative economic models to determine the most cost effective support solution for the system.

Where does organizational maintenance occur?

Organizational, or O-level maintenance occurs at the organizational unit level, for example by a single maintenance squadron as part of an aircraft wing .

What is step 2 in maintenance?

Step two compiles the hard costs of maintenance, including the cost per man hour of on-site and consultant labor, the time it takes each type of labor to complete a task, and at what total cost.

What is LORA analysis?

Level of Repair Analysis (LORA) is a decades-old strategy of asset management that examines not just the level of criticality of an asset but the business case around its upkeep. You can think of it as a decision-making logic that drives what level of maintenance is applied to various assets.

Process

LORA analysis establishes who and where each unit will be repaired and determines if it is more cost effective to discard an item than attempt to repair it. While this kind of analysis seems costly and unnecessary, at enterprise scales over many years, significant cost savings can be realized. [citation needed]

Decision considerations

Non-economic LORA decision criteria are a list of rules or guidelines that are used to determine if there is an overriding reason why maintenance should be performed. Some organizations have policies that any item costing less than a predetermined price level will be discarded and replaced rather than be repaired.

How to understand level of effort?

The best way to understand level of effort is by looking at common support activities that take place in almost any project. We’ve a few level of effort examples below.

How to estimate effort?

Assign Numerical Value: Perhaps the most clear-cut method of effort estimation is assigning each task a numerical value on a predetermined scale. Many teams use the default 1-10 scale, but it’s not uncommon to see smaller or larger scales. When a scale has been set, individual team members will then assign tasks values and compare their estimations with each other. Together, the entire team will come to a consensus on where each task should fall on the scale.

When Should LOE Be Calculated?

The level of effort should be calculated during the planning phase of a project when tasks are being created. Tasks with a higher level of effort require more work to be completed. Generally, this work takes place at regular intervals throughout the task or project, so it’s important to understand how much total effort it will require.

What is the purpose of the level of effort scale?

This scale should be used to show LOE for all tasks in comparison to one another. Different projects may use different forms of level of effort scales depending on their size, scope and other characteristics. This is fine, so long as the team understands the level of effort scale being used and the criteria for plotting tasks on the scale is consistent.

How to rank tasks in teams?

Rank by Priority: It’s always a good idea to get the team on the same page about the priority of tasks. One way to do this is by having them assign each task a level of priority in the form of a number. Then, tasks can be listed in order of highest priority or lowest priority. The higher priority a task is, the higher level of effort it may require to get it done.

How to know a task's LOE?

In order to know a task’s LOE, you must practice something called effort estimation. Effort estimation is the process through which we approximate how much time, energy or money deliverables will demand so that we can rank this on a scale.

Why is it important to establish the level of effort during the planning phase?

Establishing the level of effort during the planning phase helps spread workload evenly and allows for a more accurate schedule. If certain team members are assigned to too many high LOE tasks in their workflow, it may be time to redistribute tasks.
