ELSA is an application concerning avalanche path analysis which takes advantages of a reason maintenance system. In order to fully describe it, the tool on which the ELSA application is developed - Shirka/TMS - is first described. It is noteworthy that the RMS on Shirka is a special one. It is only used for cache consistency maintenance. As a consequence, the importance of Shirka/TMS in ELSA is in preserving cache consistency rather than defaults assumptions and backtracking. Then, the processing of the ELSA system is presented, emphasizing on the use of the RMS: the RMS of Shirka is critical for the performances of the whole system. This is illustrated in the third part in which are given some comparison of the use of ELSA with and without its RMS, in order to highlight the advantages of such a device.
