AS IEC 60300.3.12-2004 pdf – Dependability management Part 3.12: Application guide—Integrated logistic support.
1 Scope This part of IEC 60300-3 is an application guide intended for use by a wide range of suppliers including large and small companies wishing to offer a competitive and quality product which is optimized for the purchaser and supplier for the complete product life cycle. This standard can be applied to both commercial and military products. It describes the process of ILS, and the various minimal common practices and logistic data analyses that should be undertaken to meet this objective. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of IEC 60300. For dated references, subsequent amend- ments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of IEC 60300 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below.

3.2 integrated logistic support (ILS) management method by which all the logistic support services required by a customer can be brought together in a structured way and in harmony with a product 3.3 line replaceable unit (LRU) lowest level of assembly, subassembly or component which is recommended to be exchanged during maintenance to effect a repair at a specified repair level 3.4 logistic support all material and resources required for the operation and maintenance of a product including both hardware and software 3.5 logistic support analysis (LSA) selective application of a range of tasks undertaken to assist in complying with supportability and other ILS objectives 3.6 provisioning process of determining and acquiring the range and quantity of spares required to operate and maintain the product 3.7 supportability degree to which product design characteristics and planned logistic support resources meet product operational utilization requirements 3.8 trade-off determination of the optimum balance between product characteristics (cost, performance, and supportability) 3.9 support concept recommended support policy and procedure for a particular product specific to a particular user or application
5 Principles of Integrated Logistic Support (ILS) 5.1 ILS objectives The objectives of ILS are to a) permit support considerations to be integrated into product design; b) develop support arrangements that are consistently related to design and to each other; c) provide the necessary logistic support at the beginning and during customer use and disposal at optimum cost; d) allow improvements to be made in the support of a product throughout its life. Meeting these objectives should result in an improved product and support system that minimizes the through-life cost while meeting the needs of the customer and business. 5.2 Application of ILS The application of ILS to the design and development of a product aims to ensure that all the logistic implications of introducing the product have been properly considered so that it can be supported in the most cost-effective way. The application of ILS is also applicable to large systems, such as a power plant or a paper mill, and provides a methodology for the identification and optimization of the support requirements for the individual products that constitute the plant. Logistic Support Analysis (LSA) is an analytical process that is a part of ILS and comprises a series of analysis tasks to influence the design to improve its supportability and to ensure support requirements are adequately identified and provided. The degree of application of ILS and the associated LSA will vary accordingly with the degree of design freedom, technical complexity, cost of the product and other factors.
