Logistics Support Analysis

Logistics Support Analysis (LSA) identifies and sizes the resources required to operate and maintain a system.

It contributes to defining the support system and to optimising overall ownership cost.

Maintenance needs analysis

Maintenance requirements are determined from system characteristics, functions and identified failure modes.

Maintenance tasks are then defined according to performance objectives and operating constraints.

Logistics breakdown structure

The logistics breakdown structure organises the system into the different levels required for support analysis.

Support database

Support information is centralised in a logistics database containing equipment, maintenance tasks, spare parts and support resources.

Life Cycle Cost

Life Cycle Cost analysis considers acquisition, operation, maintenance and support costs.

The objective is to identify solutions providing the appropriate balance between performance, availability and overall cost.

Reliability-Centered Maintenance

Reliability-Centered Maintenance (RCM) defines maintenance policies based on system functions, failure modes and their consequences.

viattech Q&S combines RCM with FMECA studies to define and optimise maintenance tasks.

Failure mode identification

Failure modes that may affect system operation are identified and their consequences analysed.

FMECA and functional analysis

FMECA analyses systematically failure modes, effects and criticality.

Maintenance task definition

Analysis results are used to define maintenance tasks, intervals and required resources.

Maintenance plan optimisation

Maintenance plans are optimised according to availability objectives, operating constraints and associated costs.

Maintainability and testability

Maintainability and testability are essential characteristics for optimising maintenance activities.

Maintainability analysis

Maintainability analysis evaluates how easily equipment can be diagnosed, repaired and returned to service.

Equipment testability

Testability is the ability of a system to support fault detection, localisation and identification.

Test and diagnostic resources

Test, diagnostic and troubleshooting resources are defined according to maintenance requirements and availability objectives.

Level of Repair Analysis

Level of Repair Analysis (LORA) determines the level at which a repair should be performed.

The objective is to compare possible maintenance solutions and to identify the most appropriate technical and economic organisation.

Repair-level analysis

The analysis determines whether equipment should be repaired on site, in a specialised workshop or by the manufacturer.

Maintenance resources

LORA results are used to size the human, technical and logistical resources required at each maintenance level.

Maintenance plan and operational readiness

The maintenance plan translates study results into practical activities during operation.

viattech Q&S supports customers in defining and optimising their maintenance policy.

Preventive maintenance

Preventive maintenance is performed before a failure occurs or according to predefined criteria.

Corrective maintenance

Corrective maintenance is performed following failure detection.

The objective is to reduce diagnosis, repair and restoration time.

Maintenance performance monitoring

Performance indicators are used to monitor maintenance effectiveness and identify opportunities to improve equipment availability.

Maintenance engineering and RAMS

Maintenance engineering is closely connected with RAMS engineering.

Reliability and maintainability studies provide an important basis for defining maintenance strategies.

Maintenance directly contributes to system availability and performance.

These activities are closely related to our RAMS and dependability engineering services.
