Abstract
| Accelerator driven facilities are and will have to be designed to a very high level of reliability and beam availability to meet expectations of the users and experiments. In order to fulfil these demanding requirements on reliability and overall beam avai lability, statistical models have been developed. We compare different statistical reliability models as well as tools in terms of their performance, capacity and user - friendliness. In addition we also benchmarked some of the existing models. We will pres ent in detail a tool being used f or LHC and LINAC4, which is based on the commercially available software package Isograph, and a tool using Excel Visual Basics for Applications. |
