ABSTRACT
The DEMATEL method has been applied in the Decision Sciences in several studies. However, one has not been able to apply DEMATEL directly to a multi-criteria matrix formed by a set of alternatives and a set of criteria yet. In order to approach this, we propose a novel way to apply DEMATEL to a multi-criteria matrix for ranking a set of alternatives according to their performances in a set of criteria. For accomplishing this, we consider the set of alternatives in a classical multi-criteria problem as the set of components used in a usual DEMATEL application. To set up the influence degree among studied components, we used the preference index of PROMÉTHÉE II. Such preference index takes into consideration the performances of alternatives on all criteria to establish each influence degree. Thereby, we denote the influence degree by preference degree. This new approach is applied to a case study and results are compared against those of three multi-criteria methods. It is then possible to note small, understandable differences among the rankings. This hybrid approach has therefore shown to be theoretically sound and feasible to be used in the practice of Multi-Criteria Decision Analysis.

INTRODUCTION
The DEMATEL (Decision
Making Trial and Evaluation Laboratory) method was developed by Gabus and Fontela (1972) for the
structuring of complex problems (GABUS; FONTELA, 1973; FONTELA; GABUS, 1976).
The complex problems studied by DEMATEL are based on a set of components in
which each component can exert an influence degree over each other (LI et al.,
2014; Gölcük; Baykasoğlu, 2016). That is, this
method can be used whenever there is a cause-effect relation among the studied
components. DEMATEL can therefore confirm the interdependence between variables
in a decision system (TSENG, 2011).
In the cases studied by
DEMATEL, one seeks to identify the received and exerted impacts from each
component. After this, this method computes the full involvement and the net
effect of each component in the decision system (Altuntas; Dereli, 2015). Through these attributes, it is
possible to develop the impact-relationship map, a two-dimensional chart used
to illustrate the causal relations among components in the studied system
(WANG, 2012). The DEMATEL method has thus been applied in several fields of
study for selection, industrial planning, competence evaluation, etc. (SALLUM;
GOMES; MACHADO, 2018; SHIEH; WU; HUANG, 2010).
Among the various cases
that have been approached by DEMATEL, one should highlight problems of a
multiple criteria nature as some of the most important ones. It is important to
emphasize that DEMATEL is not a multiple criteria method in itself. However, it
has been applied in combination with Multiple Criteria Decision Making (MCDM)
methods in many situations (QUEZADA et al., 2018; Baykasoğlu; Gölcük, 2017). DEMATEL has been used in
MCDM field mainly to identify interrelations in a set of criteria (HSU, 2012).
Besides, DEMATEL results can also be used in many other steps of a hybrid MCDM
template.
Considering the
potential for compatibility between DEMATEL and the MCDM field, we propose in
this paper an approach to use directly the DEMATEL method in a classical MCDM
problem. In order to accomplish this, the influence degree between the studied
components (alternatives) must be determined through the behavior of each
alternative on all criteria of a multiple criteria matrix. We go to reinterpret
some DEMATEL issues in order to take its methodology for obtain a ranking of
alternatives based in the mutual influence between alternatives, according to
their behaviors in the criteria.
A classical MCDM
problem is given in a multi-criteria matrix, a matrix formed by a set of
alternatives and a set of criteria (VELASQUEZ; HESTER, 2013; BELTON; STEWART,
2002). Then, to identify the influence degree between studied alternatives we
use a MCDM method. For this, we use the PROMÉTHÉE II (Preference Ranking
Organization Method for Enrichment of Evaluations II) method’s preference index
in order to obtain the influence degree of each alternative over the others.
For this reason, we call the influence degree as preference degree. This happen
because the preference degree is performed without there is a formal
cause-effect relation between alternatives. The preference degree measures how
much an alternative is preferable to the other according to its behaviors on
all criteria.
As the PROMÉTHÉE II
method performs a pairwise comparison between alternatives criterion by
criterion, it is possible to know on a 0 to 1 level the preference of each
alternative over the others through its preference index (BRANS; VINCKE, 1985).
Thus, with this methodology, we can perform the preference degree between
studied alternatives and, after that, to apply DEMATEL. For test this approach,
we use a part of the Jati and Dominic’s article
(2017) database as a case study and to apply it in order to obtain a ranking of
alternatives through DEMATEL methodology from a multi-criteria matrix.

DEMATEL
The basic element to apply the
DEMATEL method is a set with 2 or more components (alternatives or criteria)
forming a decision system. In this set, the decision maker should establish the
influence degree that each component exerts over the each other. For this, it
should be used a verbal scale from 0 to 4 in which: 0 is no influence; 1 is low
influence; 2 is moderate influence; 3 is high influence; and 4 is very high
influence. This scale can be extended according to the decision maker’s
preference. Through the influence degree values the direct-influence matrix A should be built. The matrix A is a square matrix where the numbers
of rows and columns are equal to the components number n. Thus, aij
is the influence that element i in the matrix’s row exerts over element j in the matrix’s column. The diagonal
of the matrix values must be 0, because one component cannot exert influence
over itself.
After to build the matrix A, it should be calibrate according to
the Equations 1 and 2 generating the direct-relation matrix D.

Where
Next, the total-influence matrix T should be calculated through the
Equation 3:
(3) |
In Equation 3, I is an identity matrix and (I-D)-1
is an inverse matrix. Then, the sum of each row ri of matrix T
(Equation 4) should be calculated as well as the sum of each column ci of
matrix T (Equation 5).
(4) |
|
(5) |
The sum of rows of each component (ri)
represents the impact of one component over the others in the system. The sum
of each column (ci)
represents the received impact of each component by the others in the system.
The addition ri+ci
should also be made for each component, representing the full involvement of a
component in the system. Similarly, the subtraction ri-ci represents the net effect of a component in the
system.
In addition, an impact-relations
graph can be built. This graph is created to visualize the causal relationships
between components in the system, where ri+ci is the horizontal axis and ri-ci the vertical axis. The
result of ri-ci, if positive, classifies
a component as an influencer inside the system. That is because its exerted
impact is higher than its received impact.
Moreover, the result of ri-ci,
if negative, classifies a component as influenced inside the system, that is,
its exerted impact is lower than its received impact.

THE PROMÉTHÉE II-DEMATEL APPROACH
The approach here presented aims to
apply DEMATEL directly in a MCDM problem. Although DEMTAEL works with
cause-effect relations between its studied components, we believe that the
classical MCDM problems are questions that can be solved by DEMATEL. This
occurs because in a set of alternatives studied in a multi-criteria matrix some
alternatives can be obtain a good performance just in some criteria and other
alternatives can be obtain a good performance on other criteria, framing the
decision-making difficult (Pomerol;
Barba-Romero, 2000; Belton;
Stewart, 2002). This kind of conflict observed in those cases remits to
the problems of interrelations between components that can be solved by
DEMATEL.
By doing this, for apply DEMATEL,
firstly, we should establish the influence degree that each component exerts
over the others. As we work with a MCDM problem, the studied components are a
set of alternatives and the influence degree of each alternative over the
others should be extracted from the behaviors of studied alternatives on
designed criteria for the studying.
As in a MCDM problem there is not,
necessarily, a formal cause-effect relation between alternatives, considering
the interdependence between criteria, we call the influence degree as
preference degree. The goal of preference degree is identifying how much an
alternative is better the other in a multi-criteria context. When we have the
preference degree of each alternative over the others in a decision system,
this problem can be solved by the DEMATEL methodology.
Then, for measure the preference
degree of each alternative over the others through their behaviors on the
studied criteria; we use the PROMÉTHÉE II method’s preference index. This index
is used because measures the value of all differences between pair of
alternatives on all criteria. Besides, positives and negatives values are measure
reciprocally.
Not all MCDM methods measure the
values of all performance differences between alternative pairs, criterion by
criterion, for example the ELECTRE (ÉLimination Et Choix Traduissant la REalité) methods (POMEROL; BARBA-ROMERO, 2000). Besides,
other multi-criteria methods do not make all possible comparisons between
alternatives. That is, after to designee the first distance or preference
between two alternatives on a certain criterion, the second of the same pair is
an inverse value from the first. As examples this, we can notice the AHP
(Analytic Hierarchy Process), ANP (Analytic Network Process) and MACBETH
(Measuring Attractiveness by a Categorical Based Evaluation Technique) methods
(BELTON; STEWART, 2002; SAATY, 1980; SHARMA; GARG, 2015; AKYÜZ; TOSUN; AKA,
2018).
The TODIM (TOmada
de Decisão Interativa e Multicritério) method makes a comparison between pairs of
alternatives, criterion by criterion, but it measures in a dissimilarity way
positive and negative differences (GOMES; LIMA, 1991). Some methods, such as
TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) and
VIKOR (VlseKriterijuska Optimizacija
I Komoromisno Resenje), do
not make a pairwise comparison between pair of alternatives, because they are
based on a compromise solution (OPRICOVIC; TZENG, 2004). For those reasons, we
understand the PROMÉTHÉE II methodology as the best representative way to
measure the preference degree.
3.1.
Setting the preference degree
through PROMÉTHÉE II method’s preference index
For the PROMÉTHÉE II method’s
preference index calculating is necessary a set of alternatives A = {ak |k=1, …, n}, where k is a generic alternative’s ordinal number and n is the maximum number of alternatives
in the multi-criteria matrix; a set of criteria C = {cj
|j=1, …, m}, where j is each
criterion cj’s ordinal number and m is the maximum number of criteria in
the same multi-criteria matrix; X = {xkj
|k=1, …, n; j=1, …, m}, where xkj is the
performance evaluation of each alternative k
according to each criterion j; and W
= {wj |j=1, …, m} is the set of weights wj
assigned to each criterion according to the decision maker's preferences.
After that, the decision maker must
choose a preference function for each criterion. The preference function is the
way to measure the difference of performances between alternatives on each
criterion. There are 6 preference function types. We suggest in this approach
the use of the V-Shape (Type 3) preference function on all criteria. This
preference function measures the difference of performances between
alternatives on each criterion using all values from 0 to 1 with only one
threshold, the preference threshold p.
Some preference functions use just
some specific values to measure those differences. Thus, the V-Shape preference
function measures the differences between alternatives in a more sensitive way
than those. The Linear (Type 5) preference function also uses all values from 0
to 1 but using 2 thresholds. It is important emphasize here that we do not
express decision maker’s preferences. That is, we use a part of PROMÉTHÉE II
method in order to calculate the preference degree that each alternative exerts
over the others according to their behaviors in the studied criteria.
For compute the threshold p for each criterion using V-Shape
preference function, the threshold p
should be computed by Equation 6.
(6) |
In the Equation 6, pj is
the preference threshold of the criterion j;
aj+ is the value of the best
performance in criterion j; and the aj- is the worst performance in
criterion j. In this way, the larger
difference between 2 performances is measured as 1. Differences between
performances that results 0 are measured as 0. Any other value from those
differences is measured proportionally between the larger difference value and
the difference equals to 0.
Next, the value of the V-Shape
preference function for each pair of alternatives must be computed according to
Equation 7.
(7) |
In Equation 7, Pj (a1,a2) is the value of the preference index
of a1 over a2 in criterion j; dj (a1,a2) is the performance differences
between the alternatives a1
and a2 in criterion j; p
is the preference threshold of the criterion j.
Finally, we can perform the
preference degree for each pair of alternatives through the preference index
following Equation 8.
In Equation 8, π (a1,a2) is the preference index of a1 over a2; wj is the weight of the criterion j. By doing this, π (a1,a2) is the value of the preference
degree of a1 over a2, which is a number from 0
to 1.
After calculating the preference
degree of each alternative over the others, the direct-influence matrix A of
the DEMATEL method can be build. Now, to provide continuity to this approach,
it is enough to apply DEMATEL following the steps outlined in the Section 2.

CASE SUDY
Jati and
Dominic (2017) approached in their article the problem of to rank 27 Indonesian
universities’ websites considering 4 criteria. For this, they applied the
PROMÉTHÉE II method. The criteria used by those authors with their weights
computed by Entropy method and their sense (maximization or minimization) were:
· C1: Presence: number of
pages of the main web domain of the institution, it includes all sub domains
that share the web domain and all types of files including PDF. Its weight is
0.17. This criterion should be maximized;
· C2: Visibility: number of
external networks that have backlinks to the institutions' web pages. Its
weight is 0.33. This criterion should be maximized;
· C3: Openness: number of citations from the main
authors by Google Scholar citations. Its weight is 0.23. This criterion should
be maximizing; and
· C4: Excellence: number of
academic articles published in international journals of high impact among the
10% most cited in their respective scientific disciplines which data is
provided by Grup Scimago
(2010-2014). Its weight is 0.27. This criterion should be maximized.
For this case study, we use the 10
best universities ranked by Jati and Dominic (2017)
in order to form the set of alternatives. We also use the same criteria and
their respective weights. Then, our goal is to rank those 10 universities
through their performances on the criteria explained above by DEMATEL. The name
of each university and their performances on each criterion are shown by Table
1.

Preference Degree Setting
Now, before applying DEMATEL, we
should establish the preference degree of each alternative over each other one.
For this, we must calculate the preference index of the PROMÉTHÉE II method.
The first step for this is to calculate the threshold p for each one of 4 criteria that is necessary to use the V-Shape
preference function. Table 2 shows the threshold values for each criterion
calculated according Equation 6.
Table 2:

After to calculate the threshold of
each criterion, we should perform the value of preference function following
Equation 7. Next, we can achieve the preference index value that is the
preference degree value accordingly with Equation 8. Table 3 presents the value
which each alternative exerts over each other alternative.

In Table 3, the diagonals are equal
0 because one alternative does not exert influence on itself. In addition, when
we see the first row with second column, we see the number 0.4534 that is the
preference degree from UI over ITB and as so on for the other cases.
Then, through the Table 3 data, we
can apply DEMATEL following the Section 2 steps. Table 3 is the
direct-influence matrix A. The

As our goal is to establish a
ranking of alternatives, we use the net effect value r-c in order to obtain this ranking. The net effect represents the
difference between the exerted and received impacts of each alternative. For
this reason, we choose it to rank the set of alternatives. Table 6 presents the
ranking of alternatives performed by DEMATEL.

Observing the ranking in Table 6, we
can notice that UI, UGM, and ITB are better alternatives than the others. This
is happening because those universities are classified by DEMATEL as
influencers. In the influencers group, UI is the best university.

Comparing PROMÉTHÉE II-DEMATEL
Approach with other MCDM Methods
In this Section, we compare the
PROMÉTHÉE II-DEMATEL approach results against the results reached by other MCDM
methods for the same database presented in Table 1 using the same weights of
criteria. Next, we use the PROMÉTHÉE II method using the Usual Preference
Function (Type I) for all criteria. The Usual Preference Function will be used
because the authors Jati and Dominic (2017) also use
this preference function for all criteria in their original database.
We then use the TOPSIS method (Hwang; Yoon, 1981; SREENIVASULU;
SRINIVASARAO, 2016) and the TODIM method (Gomes;
RANGEL, 2009). In the TODIM application we use θ equal 1.0 for all
criteria. Table 7 presents the rankings reached by PROMÉTHÉE II-DEMATEL approach,
PROMÉTHÉE II method, TOPSIS method and TODIM method.

Observing the results from Table 7,
PROMÉTHÉE II, TOPSIS and TODIM are unanimous in ranking UI, UGM and ITB as the
three top universities just like the
PROMÉTHÉE II-DEMATEL approach did. This fact is more telling in the
PROMÉTHÉE II-DEMATEL approach, because this approach classifies those
universities as influencers inside the decision system. There are some
divergences among the rankings in other positions, except in eighth position
that is always occupied by ITS. The TODIM method is the single method that
classifies UNAIR and UNHAS, respectively, in last positions. Those positions
are opposite in the other methods. TODIM also diverges from the other methods
about the seventh place, ranking UNPAD in a position below UB.

CONCLUSION
We proposed a new approach to apply
DEMATEL in order to solve MCDM problems called PROMÉTHÉE II-DEMATEL. We present
that in a MCDM problem an alternative can exert an influence degree over
another alternative without there is a formal cause-effect relation between
them. For this reason, we called the influence degree as preference degree. The
PROMÉTHÉE II method’s preference index is used for setting the preference
degrees between components in the decision system. This occurs because the
preference degree is setting from the behaviors of alternatives on each
criterion in a multi-criteria-matrix.
We applied the PROMÉTHÉE II-DEMATEL
approach in a MCDM problem to rank a set of 10 universities according to their
performances on a set of 4 criteria. The resulting methodology is theoretically
sound and provides meaningful results when applied in a MCDM problem. Besides,
we applied PROMÉTHÉE II, TOPSIS and TODIM multi-criteria methods to the same
problem and the results ratify the PROMÉTHÉE II-DEMATEL approach consistency.
Thus, this approach opens a new way to study MCDM problems using the DEMATEL
method.
