I'm doing some performance evaluation of call handling systems
such as those we use for escalating customer problems to the local
DEC office, and then if no resources available, escalating the
problem to regional centres and then if no ressources available,
escalating to "country" level,and then if no ...... etc. The branching
between problem solving centres is according to a transition
probability matrix.
I'm trying to model this as a multichain BCMP queuing network
as I'm interested it chain thru'puts, queue sizes at each centre,
utilization factors etc.
That is, I'm assuming a product-form solution and wish to use
Mean Value Anaysis (MVA) approach where recursive relations can be
used without any danger of floating point overflow. I would also like
to deal with open, closed and mixed networks.
Can any one point me to an already existing SW package that does this
sort of thing. There are algorithms called MVA, RECAL, and MVAC.
Anyone know where these or similar ones have been implemented ?
Many thanks to all and one.
Brian

PAWS is, I believe the tool used most often within Digital, though I do
not know who you could contact about getting it. It is Third-party
software and has to be paid for.
As a start you could try the CAPACITY_PLANNING notes conference, or the
VINO::DECCP, or VINO::VPA conferences. You could also directly contact
Lindsey Stephens (on VINO::), who is one of the developers of the
modelling software in VPA. Also, Jee Pang, who is one of the
Developers of the DECcp modelling software (which does in fact
implement MVA for a mixed model (ie. VMS)).
