Following to article of “Fuzzy Delphi
Method to Design a Strategic Plan” posted on link: http://emfps.blogspot.com/2012/02/fuzzy-delphi-method-to-design-strategic.html,
the purpose of this article is to utilize a new simulation model to design the
strategic plan instead of FDM where I had already depicted this simulation
model in article of “Application of Pascal’s Triangular Plus Monte Carlo
Analysis to Appraise the Wisdom of Crowds” on link: http://emfps.blogspot.com/2012/05/application-of-pascals-triangular-plus_08.html.
The most important finding is to show the advantages of this simulation model
to design the strategic plan in which I have compared the results with FDM.
The template of this article is the same
“Fuzzy Delphi Method to Design a Strategic Plan”.
Methodology
As you remember, I started an example of
Driving Forces (DF) in article of “Fuzzy Delphi Method to Design a Strategic
Plan” where I chose 14 experts to respond my survey questionnaire about the
ranking of driving forces issues as follows:
DF
|
P
|
M
|
O
|
DF1
|
1
|
5.79
|
10
|
DF2
|

|
6.36
|

|

Now, I am willing to use this simulation model step
by step instead of FDM as follows:
I1
I look at the minimum and maximum of the ranking responses by experts for each
driving force. In this case, I do not need to repeat data collection from
experts just like to Delphi Method because the experts should only answer one
number. In fact, this method do not need to have Linguistic Values such as Pessimistic = P, Most likely = M,
and Optimistic = O. Therefore, the accuracy of the responses will increase only
by one time data collection.
I2
I assume that I have collected the data from 50, 100 and 200 experts so that I
expand the numbers into a limited range of the ranking by increase of the
experts where real number of the experts is 14. As the matter of fact, I can
say you that it can be the similar the repetitions in Delphi Method.
I3
I utilize the simulation model mentioned in article of “Application of Pascal’s
Triangular Plus Monte Carlo Analysis to Appraise the Wisdom of Crowds” on link:
http://emfps.blogspot.com/2012/05/application-of-pascals-triangular-plus_08.html.

continuation of this article)
Discussion and Data Analysis
Referring to the example included in article of “Fuzzy
Delphi Method to Design a Strategic Plan”, you can see that there are three
ranges of the ranking responded by the experts below cited:
Xmin = 1, Xmax
= 10
Ymin
= 2, Ymax
= 10
Zmin = 2, Zmax
= 9
By using of this simulation model, the final results
for 50, 100, and 200 experts will be as follows:
50 Experts:
Xmin= 1 to Xmax = 10

Regarding to the threshold as alpha-cut which was equal to 6 (alpha-cut = 6), the
appropriate driving forces for responses of 50, 100, and 200 experts are as
follows:
The appropriate driving forces 50
Experts:
All driving forces will be considered by the experts
as the most impact factors except (D13) which is “Regulatory influences government policies changes”.
The appropriate driving forces 100
Experts:
All driving forces will be considered by the experts
as the most impact factors except (D13) which is “Regulatory influences government policies changes”.
The
appropriate driving forces 200 Experts:
In this
case, the appropriate driving forces are:
DF2: Increasing globalization
DF7: Marketing innovation
DF11: Growing buyer preferences
for differentiated products instead of standardized commodity product (or for a
more standardized product instead of strongly differentiated products)
DF14: Changing societal concerns, attitudes, and
life styles
As you can see, the final results for 200 experts
are the similar to the final results of the article of “Delphi Method to Design
a Strategic Plan” posted on link: http://emfps.blogspot.com/2012/02/fuzzy-delphi-method-to-design-strategic.html
Conclusion
Finally, let me tell you about the advantages and disadvantage
of this simulation model in comparing with FDM as follows:
Advantages:
Ø To delete Linguistic Values such as Pessimistic
= P, Most likely = M, and
Optimistic = O
Ø To
eliminate the repetition of the experts’ responses
Ø To
increase the accuracy of the responses
Ø To
save the cost and the time
Disadvantage:
In the reference with above item (I1),
I have still doubt about the increase the accuracy of the responses collected
only in the first round because it is possible, in the second or third round,
the range of the ranking will increase. This simulation model is very sensitive
to be changed the minimum and maximum of the ranking.
