Detailed Description

struct line::ctmc::NetworkStruct< T >::Region

FINITE CAPACITY REGIONS, MATLAB's refreshRegions output.

A region caps the jobs (and the memory) held ACROSS a set of stations, which no per-station capacity can express: three stations each able to hold 5 jobs but at most 6 between them is a region, not three caps.

cap(i,r) is the class-r bound at station i, cap(i,K) the station's global bound, and -1 means unbounded – the reference's sentinel, kept rather than translated to infinity because it is compared with ~= -1 to test MEMBERSHIP as well as boundedness.

rule(r) decides what an arrival that would violate the region does: DROP loses it, WAITQ parks it outside every station's own queue, which is why the CTMC needs a separate waiting-room state per region and not just a filter on the enumerated space.
