ASSESSMENT OF THE REGIONAL NETWORK MODEL
Applying Sugeno integral we have obtained a separate
mark for every input parameter and observed
network. Th e marks are based on diff erent groups of
criteria in order to show the correlation between input
parameters within the same group. We have got
the fi nal mark for every network as arithmetic mean
of all other marks for diff erent groups of criteria,
which is shown in the following formula
Evaluation of input parameters
Keeping in mind the literal mark defi ned in Table
1 and the previously mentioned equation, we can
calculate the fuzzy number for input parameters-criteria.
Th e fuzzy number is calculated for the group of
input parameters, so we would consider the mutual
infl uence of parameters inside every group.
Th e criteria for establishing the optimal network
choice are divided into four groups, as it is shown in
Table 5. We apply the Sugeno integral on the groups
with literal marks, while the group with numerically
shown marks was defi ned in the previous chapter.
In Table 5 are shown linguistic marks for the
infl uence of the observed parameter on the model,
which came to be as expertise of set out advantages
and disadvantages for every suggested model.
For the evaluation of every individual input parameter
it is necessary to defi ne the function of the
network mark f
NETWORK . To this function, the values
from the group of marks {0.11, 0.33, 0.66, 0.88}
are added, which are received based on the group of
available literal marks and transformations of those
marks in the fuzzy value.
By scaling the infl uence of infrastructure spreading
(SI) in the range from 0 (no aff ect on the fi nal choice)
to 1 (it only aff ects the fi nal choice), we received results
showcased in Table 11. Th e table shows that for
any coeffi cient k (k), the optimal future network
choice is the FTTH access network. Th e received results
show the nonexistence of breaking points.
Conclusion
In this paper, a completely new model of input
parameters evaluation is represented. It has a goal to
choose the future telecommunication network. Th e
results are received by applying the model to an actual
situation. Th ey confi rmed the initial expectations
that were received in the previous analysis.
Th is paper represents a systemized approach to
the future telecommunication access network choice,
which has usage in the business environment. Th e
suggested methodology and the defi ned input parameter
evaluation model can represent a base for
making the decision about the access network choice
in other environments as well, with the input parameters
correction.
