Logistic Support Analysis (LSA) is the principal tool of ILS. It is the primary means by which the objectives of ILS are achieved and comprises a series of structured analytical tasks aimed at developing the optimum support by:
• Identifying support planning and management requirements for a system/equipment project;
• Defining the support requirements for a system/equipment, identifying major cost drivers and risks;
• Developing alternative support solutions and determining the optimum solution through the use of trade-off analysis;
• Identifying the required resources to implement the chosen support solution
• Validating the support solution adopted, once the system/equipment enters service.

The result of the analyses is recorded within an Logistic Support Analysis Record (LSAR) database and provides the information necessary for the logistic support resources such as:
• Initial provisioning of spares;
• Support and Test Equipment;
• Publications;
• Training;
• Manpower;
• Facilities;
• Packaging, Handling, Storage and Transportation

The LSAR will be subject to regular review and update via PDS activity throughout the life of the system/equipment.

Failure Modes, Effects and Criticality Analysis (FMECA)
The FMECA is a tool used to examine systems or processes and provides a method of identification and assessment of potential design weaknesses. It is used to support a number of different engineering activities. These include:
• Reliability Analyses - to identifying all the required logistic support resources from a logistic and / or safety viewpoint. Such areas should then be targeted for possible design changes which may improve reliability.
• Maintainability Analyses – to records and/or detail any areas of the design which require some form of scheduled maintenance activity.
• Testability Analyses – to include a detailed analysis of detection methods including any Built in Test (BIT).
• Safety Analyses – using failure mode criticality results to feed the Fault Tree Analyses.
• It is important to ensure that all components, sub-assemblies, modules, LRUs etc. are represented within the system and at the correct level in the system hierarchy. There are a number of different tools and techniques used to assist this process, such as Equipment Breakdown Structure (EBS), Reliability Block Diagrams (RBD) and Functional Block Diagrams (FBD).

Quorum can conduct the FMECA to the customer defined requirements or in accordance with any military or defence standard.

FMECA is normally conducted as part of the ARM Programme.

Reliability Centred Maintenance (RCM)
RCM methodology is the analytical tool used in the generation of scheduled maintenance tasks based on the outputs from the platform or system FMECA.

RCM is used to develop an optimum scheduled maintenance regime, based on a given environment that will reduce corrective maintenance activity, usually resulting in increased platform or system availability.

The ‘effects of failure’ outputs from the FMECA are analysed using sequential algorithms to precisely identify the most relevant preventive maintenance task and its optimal frequency.

Quorum Logistic Support recommends that RCM activity should be based on the foundation of ‘zero based maintenance’ in order to provide any major benefit, otherwise RCM will only increase the preventive maintenance burden as opposed to optimising preventive maintenance.

Quorum Logistic Support has Aladon trained consultants and facilitators who have applied the RCM methodology to accomplish major cost savings on behalf of Defence Suppliers.

Quorum Logistic Support provides expertise to support major defence contractors by managing or assisting in the preparation and development of:
• Assessment Studies;
• RCM Analysis;
• Evaluation Studies.

Level of Repair Analysis (LORA)
Economic LORA is an analytical methodology used to establish the most cost effective maintenance line at which an Item will be replaced, repaired or discarded based on the input of economic cost data elements modelled over a life cycle considerations.

Operational LORA takes into account the Authority’s operational requirement to conduct maintenance activity at given lines of repair irrespective of economic considerations.
