There might be changed the α

α

β

and β

and tested, which composition corresponds to 
formula (36).
Example:


148 Int. J. of Advanced Management, Vol. 10, No. 2, 2018
148
J. Stašák and P. Schmidt

Let us consider the article production, where the values α
1, 
α
2, 
β

and β

play a role of 
principle importance and the ε

item value is 0,05 and α
1, 
α
2, 
β

and β

primary values are 
postulated as follows: α

=100, α

= 200, β

= 20 and β

=30. Furthermore let us apply 
formula (36)


+ β
2
)/( α
1 + 
α
2
) = (20+30)/(100+200) =50/300= 1/6 = 0, 17
(37)
When comparing the first result value with ε

value we can see, the composition of α
1, 
α
2, 
β

and β

values does not correspond to pre-defined ε

value. As a result of that, the α
1, 
α
2, 
β

and β

values should be changed as follows:
α

=150, α

= 250, β

= 10 and β

=10 = (10+10)/(150+250)= 20/400 = 0,05 (38)
The total sum of produced articles Σ

=420.
However, when comparing the second result, we can see the composition of α
1, 
α
2, 
β

and 
β

values corresponds to pre-defined ε

value and the composition of α
1, 
α
2, 
β

and β

values 
might be considered to be optimal and the following issues might be postulated
α

≥150, α

≥ 250, β

≤ 10 and β

≤ 10
(39)
while those values indicate how the production process should be led or conducted in order 
to assure the optimal production course. The above-mentioned algorithm creates an 
integral part of Business Process Linguistic Modelling Strategy Creator described within 
section 4.5. The principle layout of Optimization algorithm is shown in Fig.5a and Fig.5b.
