 where rg and rs are used to require the general/special machine, lg and ls are used to leave the general/special machine, and S and G implement a semaphore on the two different machines.
 
 The resulting system is given by:
-$$Workers \triangleq (W|W|G|S) \setminus_{\{rg,rs,lg,ls  \}}$$
+$$Workers \triangleq (W|W|G|S) \setminus_{\{rg,rs,lg,ls  \}}$$
+We now want to show that:

+i.e., that the specification and the implementation of the factory behave the same (apart from internal actions).

+Let N denote {rg,rs,lg,ls} and x,y ∊ {E,M,D}
+We can prove that the following relation is a weak bisimulation:
