Integrated Logistic
Support (ILS) is a structured, co-ordinated and iterative approach
to the procurement of supportability of systems whether they
are bespoke or off-the-shelf. The increasing cost of system
ownership has led major customers to apply the principles of
ILS to all new projects as a mater of policy.
The objectives
of ILS are to:
- Ensure that
supportability considerations influence the design of a system
or, where this is already fixed, to define the impact of the
design on supportability
- Identify and
develop support requirements which are related to system design
and readiness objectives
- Acquire the
necessary support
- Provide the
required support in-service at the optimum Life-cycle Cost
ILS ensures that
all the elements contributing to the support of a system are
defined, analysed and costed for their impact on supportability.
The elements included in ILS are:
- Availability,
Reliability and Maintainability (ARM)
- Safety
- Life-cycle Costing
(LCC)
- Logistic Support
Analysis (LSA)
- Spare part requirements
- Maintenance
policy
- Spares Support
- Technical Publications
- Support systems
and Equipment
- Personnel
- Support outsourcing
- Off-the-shelf
hardware and software end-of-production/support strategies
- Support Facilities
- Training
- Installation
& Field Support
- Packaging, Handling,
Storage & Transportation (relating to the support process)
ILS should normally
be conducted as a collaborative effort by the system customer
and the system supplier. Design for support can be optimised
only if there is a thorough understanding of the structure,
skills and costs of the support processes.
