Integrated Logistic Support - The Source
Integrated Logistic Support or ILS is defined as - "An integrated and iterative process for developing a support strategy that optimizes functional support, leverages existing resources, and guides the system engineering process to quantify and lower life cycle costs by decreasing the demand for logistics thereby making the system easier to support."
The above definition can be more simply put as:
ILS is a technique originally developed by the US Army in the 1960s.
It arose from the need to ensure that almost any manufactured item should have supportability considered during its design and development, as well as throughout its entire life cycle. In this way the lowest affordable life cycle cost is achieved for an item or system.
Through a series of modelling techniques, the ILS process tries to identify as early as possible in the system engineering process any reliability, maintainability, testability, and availability issues in order to influence the system design and to add improvements.
The ILS management process facilitates the specification, design, development, acquisition, testing, implementation, and support of systems. Although originally developed for complex military systems, ILS is now widely used in commercial product support and in customer service organisations.
The goal of ILS is creating products and systems that last longer and that require less support, thereby reducing costs and increasing the return on investment. To achieve this, the ILS process employs a number of metrics that interact with each other to assure the highest level of system availability.
The logistic analyst employs a series of tools and procedures within the LSA (Logistic Support Analysis) process to analyse all aspects of the equipment to achieve the highest level of system maintainability and availability. Among these are the following:
The data obtained from the processes listed above feed into the following ILS elements:
When all the LSA process outputs are combined into a single, Integrated Logistic Support Plan (ILSP), the plan ensures that each of the elements is correctly addressed, resourced, and implemented to enable the system to achieve the defined operational readiness levels from commissioning through to the end of the product or system's operational life.
The Final Word
Logistic support analysts are specialists that process data to provide vital inputs to the design and support of the product or system. The more complex the system, the more vital is the role that they play as part of the greater design, manufacturing, and support team.
It could be argued that the time and money spent on a process such as LSA could be better spent elsewhere. But such a statement ignores "the bigger picture", which is the long-term support of the product or system. On a system such as a ship or commercial airliner, the support costs incurred over the 30 or more years that the equipment will be in service, are substantial. Therefore the proper implementation of LSA in the early stages of a project will result in potentially huge savings throughout the life cycle of the equipment. Further benefits are the efficient supply of ILS elements such as spares provisioning, training, and maintenance.
