....is an important supplier of elementary unit based interlockings, among other things, work is done on verification by means of process algebra [18] A free wired system used in the U.K. by British Rail is the Solid State Interlocking (SSI ) SSIs received considerable attention in the literature [1, 12, 14, 28, 34, 35]. The SSI is a more complex machine than the VPI , one reason for this is that the SSI is used to take more complex scheduling decisions than the VPI . Therefore, the more involved methods for verification as presented in these documents were not followed in this paper. But the route using the HOL ....
