SP.o_MM1KK: Returns the saturation point of a M/M/1/K/K queueing model

Description

Returns the saturation point, or the maximum number of customers that the M/M/1/K/K queueing model can support with no interference or syncronization between themselves

Usage

# S3 method for o_MM1KK
SP(x, …)

Arguments

x

a object of class o_MM1KK

…

aditional arguments

Details

The value returned is the optimal number of customers of a M/M/1/K/K queueing model. It coincides with the inverse of the serialization parameter of Amdahl's Law. That is, the value which converges the speedup func(k) = k/(1 + ser * (k-1)). It makes sense, because the saturation point is the maximun value in which no syncronization happens.
