(0.3,12),(0.3,13),(0.3,14) you choose (0.3,12)

And here (0.5,14),(1,15),(0.5,16) you (1,15)

And here you said max again u had choose (0.5,17)

Why please explain it

Compute the value of adding the following two fuzzy integers:

A={(0.3,1), (0.6,2), (1,3), (0.7,4), (0.2,5)}

B={(0.5,11), (1, 12), (0.5, 13)}

Where fuzzy addition is defined as

$\mu_{A+B} (z) = max_{x+y=z} (min (\mu_A(x), \mu_b(x)))$

Then, f(A+B) is equal to

- {(0.5, 12), (0.6, 13), (1, 14), (0.7, 15), (0.7, 16), (1, 17), (1, 18)}
- {(0.5, 12), (0.6, 13), (1, 14), (1, 15), (1, 16), (1, 17), (1, 18)}
- {(0.3, 12), (0.5, 13), (0.5, 14), (1, 15), (0.7, 16), (0.5, 17), (0.2, 18)}
- {(0.3, 12), (0.5, 13), (0.6, 14), (1, 15), (0.7, 16), (0.5, 17), (0.2, 18)}

Best answer

μA+B(z)=max x+y=z(min(μA(x),μB(x)))

A={(0.3,1), (0.6,2), (1,3), (0.7,4), (0.2,5)}

B={(0.5,11), (1, 12), (0.5, 13)}

first add the numbers(x+y=z) and write the min membership value since function is min((μA(x),μB(x)) u will get follwing 15 terms

{**(0.3,12)**,(0.3,13),(0.3,14),**(0.5,13**),**(0.6,14)**,(0.5,15),(0.5,14),**(1,15),**(0.5,16),(0.5,15),(**0.7,16),(0.5,17),**(0.2,16),(0.2,17),**(0.2,18)**}

now write all distinct elements with max membership (written in bold) value since max is there in the question

ANS WILL BE D {(0.3, 12), (0.5, 13), (0.6, 14), (1, 15), (0.7, 16), (0.5, 17), (0.2, 18)}

Please explain this step

(0.3,12),(0.3,13),(0.3,14) you choose (0.3,12)

And here (0.5,14),(1,15),(0.5,16) you (1,15)

And here you said max again u had choose (0.5,17)

Why please explain it

(0.3,12),(0.3,13),(0.3,14) you choose (0.3,12)

And here (0.5,14),(1,15),(0.5,16) you (1,15)

And here you said max again u had choose (0.5,17)

see there is no other instance of 12 other than (0.3,12) so it is directly taken as it is and

it is not chosen among (0.3,12),(0.3,13),(0.3,14)

and in the case of 15 there are 3 instances with membership .5,1, .5 and among these max i.e 1 is taken

and so on

it is not chosen among (0.3,12),(0.3,13),(0.3,14)

and in the case of 15 there are 3 instances with membership .5,1, .5 and among these max i.e 1 is taken

and so on

+1

It has been taken like,

with 12, there is only (0.3, 12)

with 13, there are (0.3,13) (0.5,13). thus max is (0.5,13)

with 14, there are (0.3,14) (0.6,14) (0.5,14). thus max is (0.6,14)

this continues for all the terms.

Last we will get,

{(0.3, 12), (0.5, 13), (0.6, 14), (1, 15), (0.7, 16), (0.5, 17), (0.2, 18)}
