@Carl Love    Thank you so muc...

@Carl Love    Thank you so much!  :)

I am so sorry to cause you trouble...

I am so sorry to cause you trouble, I appreciate your time and concern and your comprehensive explanation. Thank you so much.

Thanks a lot.

I am really grateful....

Thank you so much. It was so useful.

yes, of course and thank you...

I have formulated my problem as a LP model, something like this:

Max z=cx

Ax>=B

A'x=B'

x>=0

but one of the parameters for example A' follows a lognormal distribution function and takes stochastic values. but the other parameters are deterministic. How can reformulate this problem to include this in it and when you look at the model you can understand the stochastic or deterministic nature of parameters?

Thank you so much...

@tomleslie

Would you please show me how can I  formulate it as a mathematical stochastic program rather than maple code? (for example in constraints)

Genius...

@tomleslie @Kitonum you guys are genius...dunno how to thank you...:)

Thank you!...

@Kitonum thank you very much, i thought that it would result one scalar as if production of two vectors...i wonder how it works..thank you anyway for your time and concern.

OMG!...

how did you do that?!  I really apreciate your the brilliant idea, thank you very much..

just how did you defined the product..can you explain it a little bit more please?

Thank you...

Thank you so much for your comprehensive explanations...it was great.

@Rouben Rostamian   Thank you ... i...

Thank you ... i meant the first condition that contains "x3>=2" but i can't understand how do you find the proper plotting range...can you please help me?!

Thank you very much...

Thanks alot for your time and concern.

Still not working..:(...

@Markiyan Hirnyk Thank you very much, I edited the mentioned mistakes and i got this...

Mu(x1, x2, x3) = piecewise(`or`(`or`(x1 > 55, x2 > 10), x3 >= 2), 1, x1 < 35 and x2 <= 10 and x3 < 1, (1/10)*x2, `and`(`and`(x1 < 35 and x2 <= 10, x3 >= 1), x3 <= 2), max((1/10)*x2, x3-1), `and`(`and`(`and`(x1 >= 35, x1 <= 55), x2 <= 10), x3 <= 1), 1-((55-x1)*(1/20))*((10-x2)*(1/10)), `and`(`and`(`and`(`and`(x1 >= 35, x1 <= 55), x2 <= 10), x3 >= 1), x3 <= 2), max(x3-1, 1-((55-x1)*(1/20))*((10-x2)*(1/10))))

but still can't get a 3D plot of it...I think it's because i have 4 parameters here...i want to plot it for just 3 values of Mu (0,0.5,1) but i don't know how to put it in code...can you help me please?!
