Abstract
The joint buffer and server optimization problem (BCAP) is a non-linear optimization
problem with integer decision variables that optimizes the numbers of buffers
and servers such that the resulting throughput is greater than a pre-defined threshold
throughput. This work presents a detailed review of the current literature that
addresses allocation problems, particularly the BCAP, and a quite effective methodology
for solving this problem, which consists of a combination of approximate
methods and the Powell algorithm, a derivative-free optimization algorithm. The
methodology was applied to networks of queues in the basic topologies series, split,
and merge, producing very encouraging results that pointed at robust and homogeneous
solutions.
