TECHNICAL PUBLICATION


For some years now, we have been hearing about the "S3000L". While this term is common parlance for those who are used to it, newcomers sometimes find it difficult to understand what is behind the 6 characters. Let's try to understand it together.

The S3000L specification is the backbone of the ? S-Series ILS (Integrated logistic support), also known as the "ASD corpus" (S1000D, S2000M, S3000L, S6000T etc.).

The ASD corpus is a common denominator for a set of specifications associated with different aspects of Integrated Logistic Support. It ensures the standardisation of different engineering disciplines to enable interoperable and sustainable product support engineering to manage complex systems throughout their life cycle. This applies to systems such as aircraft or ships, which may be operated for over 40 years. In this context, S3000L aims to standardise the processes for conducting and managing LSA (Logistics Support Analysis) studies. These studies identify the best fit between the main system, which needs to be supported to ensure its mission success, and the support system, which consists of the logistics products needed to support the main system. The ASL process covers both the creation of the support repository, but also the structuring of the data and the LSAB (Logistic Support Analysis Base).

Where does S3000L come from?

S3000L is a specification that originated from a working group of industrialists from the defence and aeronautics sectors. Historically, it has its roots in the early 2000s. At that time, the original standard, 1388-1A, was already cancelled by the US Department of Defense. The DEF-STAN 00-60, which was to replace it, was considered too focused on the needs of the British Ministry of Defence. All the programmes of this period, the Typhoon, the NH-90 and the A400M, therefore saw local processes and tools developed on a bespoke basis. The idea was therefore to bring together all the best practices proven by these different manufacturers in a generic specification that would meet the needs of a maximum number of players.
Currently, S3000L is a tool deployed on the majority of French defence programmes. This specification continues to evolve in order to adapt to today's challenges and to anticipate tomorrow's challenges.

Why use S3000L?

More than just a specification, S3000L is a tool for coordinating and carrying out ASL studies with regard to expected performance, both technically and financially. It provides all the resources needed to successfully complete an ASL study:

  • A clear steering process, integrating all parties and allowing the generation of support data to be controlled,

  • A process for carrying out the analyses, which includes all the activities that can be carried out in order to specify a support system that meets the expectations of the user in its context of use,

  • A set of tools including processes, checklists and recommendations for the correct application of the principle.

It should be noted that the specification is intended to be self-supporting, therefore all the analyses to be carried out are described in the document itself.


The second aspect to consider is the data model associated with the specification. Designed to support the ASL process and to guarantee data reusability, the model is an extension of the Common Data Model based on ISO 10303-239. The objective of this structure is to be able to initiate the support system based on a technology that can guarantee the digital continuity of support data. All the information contained in the BASL will be interpretable with peripheral tools, such as IETM, ERP or PLM. Of course, this interoperability is valid within the ASD corpus itself, with tools like CMMS supporting S5000F or procurement tools supporting S2000M.


In an increasingly complex and demanding context, S3000L is therefore the tool that must be mastered to guarantee the adequacy between support data from ASL analyses and other support products. Several programmes have already used S3000L to meet the challenges facing the support world. The feedback from these different programmes has already consolidated the specification, suggesting that S3000L has a bright future ahead of it.

LGM has been involved in the development and implementation of the S3000L specification for over 10 years. Our mastery of the specification and the ASD corpus has enabled us to participate in numerous projects implementing them. We are also the developer of the eLSA solution, an ASL tool based on S3000L.
