The Reference Designation System (RDS) A common naming convention for systems and their elements

This paper introduces the Reference Designation System (RDS) as defined in the ISO/IEC 81346 standard series. The 81346 standard is a horizontal standard within ISO and IEC, and thereby a reference document for all other international standards. RDS identifies systems and their elements. A reference designation (a TAG number) is the output of RDS. The TAG numbers act as labels for the system and the system elements, and are used for instant and unambiguous recognition across different kinds of documentation and labelling of tangible products as well as non‐ tangible products such as different models in a software tool. RDS is an international “naming convention” designed for systems and their elements and a practical technique to underpin a common understanding among different disciplines. The use of RDS as a fundamental system naming convention is not widely known within the INCOSE environment. By this paper, the author wishes to reach out to INCOSE and systems engineering in general, so the principles of RDS is to be better understood and recognized as a basic part of systems engineering tool box. RDS provides generic principles and are applicable in more or less all technical disciplines; among these are civil engineering, mechanical engineering, electrical engineering and software engineering. Application examples are provided and a case example showing the economic benefit is presented.
