Some Thoughts on the Reliability of Reconfigurable Manufacturing Systems
Résumé
Reliability of manufacturing systems, i.e. the analysis of their failures, is a key component to ensure the productivity and competitiveness of industrial companies. In an increasingly volatile global environment, the ability to control internal factors of uncertainty, such as system components breakdowns, is crucial. The structure of Reconfigurable Manufacturing Systems (RMS) should help in this matter, and this advantage is often mentioned, but few papers actually examine this question in depth. In this article, we discuss the link between scalability, one of the main features of RMS, and reliability and we present a new analytical method to assess their reliability. This method offers an interesting alternative to existing approaches since it is suitable for the design phase, when few data are available, and it could lead to the development of more computationally tractable procedures for reliability assessment. A didactic example illustrates its use and the conclusions that can be drawn from its application as well as future research directions.
