Abstract: A weakest precondition based modelling and verification technique for a class of concurrent systems is proposed. A system in this class is defined by a set of non-terminating interactive sequential processes. The constituent processes are allowed to include both if-then-else and terminating while-do type control structures. The properties of the system are verified by proving the invariance of logical formulae. The technique is illustrated by considering Dekker|s two process mutual exclusion algorithm as an example.

Keywords: weakest precondition; program proving; program correctness; reactive systems; concurrent systems; verification; interactive sequential processes; mutual exclusion; mathematical modelling.
