Integrated Logistic Support

Abstract

It is generally recognised that a very large proportion (often put as high as 90–95%) of the life-cycle costs (LCC) is determined during the concept and design stages; before the system has been manufactured and often long before entry into service (EIS). Having said that, however, there is still considerable opportunity for minimising the life-cycle cost during the operational life of the system but this optimisation is constrained by the inherent reliability, maintainability and supportability of the system and its components. The role of integrated logistic support (ILS) is very much concerned with both of these areas: of ensuring the system is conceived, designed and manufactured to be operationally effective and; to provide through life support of the system to ensure that it remains so, even unto its grave (or disposal).
