Reliability, Availability, Maintainability (RAM)

RAM is the assessment of the inherent reliability of an item or system,

  • Reliability: how long it can be expected to operated before failure, based on the individual components from which it is comprised
  • Availability: its expected or required availability for operations, and
  • Maintainability: the maintenance time and complexity of repair of individual items,

which are then used to determine redundancy requirements, equipment quantity and maintenance resources required.

Failure Modes Effects Analysis
Failure Modes Effects Analysisis is the analysis of HOW the equipment can fail and what is the effect of failure.

It is designed to identify potential failure modes for an item or system, to assess the risks involved with those failures, to categorise and order in terms of importance, and to identify and either put in place mitigations or institute corrective actions to address those that can be addressed.

Failure Modes Effects Criticality Analysis
Failure Modes Effects Criticality Analysis (FMECA) is the analysis of HOW the equipment can fail, what is the effect of failure and how critical is the failure.
It is designed to identify potential failure modes for an item or system, to assess the risks involved with those failures, to categorise and order in terms of importance, identify the criticality of the failure, and to identify and either put in place mitigations or institute corrective actions to address those that can be addressed.

Level of Repair Analysis

What is Level Of Repair Analysis?

Level Of Repair Analysis combines two elements:

  •  Cost Analysis
  •  Repair Level Analysis

Cost Analysis determines Whether maintenance should be performed; which includes all costs incurred:

  • to establish and utilise a repair venue
  • the tooling required for the repair
  •  the skill of the repairer
  • in obtaining the Training required in order to perform the repair
  • in the Rates of pay of personnel conducting the repair
  • in the Cost of conducting the repair – i.e. time
  • in the Cost of the repair parts
  • in the Transport costs of getting the equipment to and from the repair base
  • in Other overheads

Repair Level Analysis (RLA) determines Where the maintenance should be performed; this in turn determines where the equipment can be repaired:

  • Operational/Organisational Level Maintenance •Light Grade Repair
  • Organic (On-board ship)
  • On the Flight Line

 

  • •Intermediate Level Maintenance •Medium Grade Repair – Mobile workshop
    •External (Along side dock )

 

  • •Deeper/Depot Level Maintenance •Heavy Grade Repair
    •Contractor (External )
    •Maintenance Depot

Reliability Centred Maintenance

Reliability Centred Maintenance
Reliability Centred Maintenance is the analysis and execution of Maintenance tasks focused on preventive replacements in order to maximise the operational period.

The focus on preventive maintenance is easily understood when consideration is given to the typical reactive type maintenance, ie “fix it when it breaks”.

In the typical reactive maintenance situation, the planned preventive maintenance gets delayed while resources are sidetracked performing emergency repairs to keep the system running after something has failed.

The delayed or cancelled preventive maintenance tasks then cause the system to be put at further risk due to it now operating beyond the planned / calculated maintenance periods. These operations beyond expected maintenance periods may place extra stress on the system, resulting in failure, diversion of maintenance resources to fix the failure, and a constant downward spiral in reliability. eg

  • An oil change that is normally scheduled to be performed at 250 operating hours gets postponed due to a separate failure elsewhere in the system.
  • The system is put back into service but the planned maintenance window for oil change has been missed and the system is now unable to be taken off-line for another 250 hours due to operational requirements.
  • So now the equipment has to run on the same oil for 500 hours rather than the planned 250.
  • If the original design did not allow for a maintenance period of twice the planned period, this may result in higher levels of contaminants and lower lubrication performance, and hence higher wear.
  • This higher level of wear may show up quickly in terms of an earlier failure of an associated piece of equipment, or it may not show up for years, instead resulting in perhaps a major overhaul at 5 years instead of the planned 10 year expected life.
  • Repeated maintenance delays may compound the unseen wear or degradation.
  • Had the oil change been able to be performed at the same time as the initial failure, the costs involved as a result of the early overhaul, or equipment failure, could probably have been avoided.

It is the desire to avoid this type of downward spiral that drives Reliability Centred Maintenance, particularly for system critical functions. (Sometimes a failure in a piece of equipment is not critical to the operation of the system, so repair on failure is acceptable. eg a light bulb failure when there is sufficient light from surrounding light bulbs to allow operations in the area to continue.)

Life Cycle Cost Analysis

Life Cycle Cost Analysis
The Real Cost of a Materiel System
Costs can be attributed to three major factors:

  •  Technology Lead
  •  Time In-service
  •  Technology Lag

Technology Lead
To achieve a technological edge, significant funds are invested in research and development (R&D).
This can lead to increased risks and hence costs and cost blow-outs.
There is a significant difference between ‘Leading edge’ and ‘Bleeding edge’ and development costs will generally be reflected in ‘Leading edge’.

Time In-service
The heavy investment in seeking leading edge technologies demands an effective return on investment.
This can lead to Materiel Systems being kept in service longer than equivalent commercial equipment.

Technology Lag

Towards the end of the capabilities life, support costs can significantly increase.
This can create problems in the identification of replacement Mission Systems.

Life Cycle Costing

Life Cycle Costing (LCC) Analysis comprises estimation and analysis techniques applied to the financial management of a capability.

It provides for the structured collection, analysis and presentation of Life Cycle Cost LCC data, to assist in decision making for mission system capabilities

When done well, LCC provides the evidence to support the expenditure on the capability.

Materiel Life Cycle

The life cycle phases are:

  •  Needs
  •  Requirements
  • Acquisition
  • In-Service
  • Disposal

The Needs Phase
The Materiel Life Cycle (MLC) starts when the capability gap is identified and a materiel solution is required.

The Requirements Phase
Proposals are developed for Government consideration.
This is generally a Two pass approval system:

  •  1st Pass Approval to investigate possible solutions
  •  2nd Pass Approval given to acquire (money is usually assigned at this point)

The Acquisition Phase
Acquisition is the process of procuring an appropriate materiel system:

  •  to meet the identified requirements
  •  value for money over the life of system
  • includes the Mission and Support Systems

Transition Into Service
Transition Plan – addresses transfer of:

  •  ILS procedures & resources
  •  management responsibility

From:
Acquisition ILS Manager to In-Service Support providers and the Project Office

In-Service Phase
The In-Service phase generally starts when the supplier delivers a materiel system.

In-Service support aims to:

  • Optimise cost of ownership
  • Ensure the capability remains fit for purpose

The Disposal Phase
Disposal is to be carefully considered, taking into account:

  • financial, environmental, security, archival, safety, and
    third-party transfer issues, e.g.
  • Foreign Military Sales (FMS)
  • International Traffic in Arms Regulations (ITARS)
