Which technique could be used in analysing capacity planning data?

A.
Combinatorics

B.
Category Theory

C.
Gate Control Theory

D.
Queueing Theory

Explanation:

Queueing Theory
Analytic models are based on a set of formulas and computational algorithms used to generate performance metrics from model parameters. Such models are normally based on the theory of queueing networks and are used to predict the performance of a system as a function of the system’s description and workload parameters.
Category Theory
Jack Park writes See http//www.tunes.org
in particluar the paper on the Arrows system by Brian Rice. IMHO this is the software project closest to the Rosen’s ideas (which use Category Theory as a Mathematics of Knowledge)
