Hi Guys, please comment and let me know what you think about this Operations Research Open Course. Your feedback is really appreciated. If you enjoy the video, please subscribe and share. All my replies here are only related to the content in my own videos. I am afraid I won't be able to answer other questions. Thanks for your understanding.

Crisp , Clear , Concise , To the point ... Thank you except for the slight error at 1:46 while writing the Cost Function

[@olgertaprendi9329]

When you find the minimum of the function: It is min (8*x11+6*x12+10*x13+9*x21+12*x22+13*x23)

[@YongWang]

Thanks, Olgerta. You are right. The second row of the objective function should be 9*x21+12*x22+13*x23 at 1:45. I'll pin your comment to the top.

[@rsadsultanov3071]

Thank you, sir. What a video! Literally taught me everything about the lesson within just 9 minutes whereas my teacher could not be able to convey the gist within whole lecture :xD

[@karl-x8p]

How did you get 20, 22, 23 for the dummy?

[@IbrahimShh]

at 1:45 why does the second line start at 9X11 and not 9X21?

[@YongWang]

You are right. This is an error. See my reply to Olgerta's comment

[@sakshikumari4805]

Is 830 the answer for this example?

[@lschan9242]

How do you get the penalty when supply less than demand

[@YongWang]

we assume these penalties are known in this example. in real-world applications, you must estimate these numbers first

[@govamurali2309]

Why there is no penalty for unused cost??

[@YongWang]

Then you can set those penalties to zero

I serch thé historique of the transportation probleme, fan you help me, thankyou

[@YongWang]

[@soryugaming7375]

I don't understand :(

[@1firat7]

I appreciate your work but I must say this is the most boring lecture in OR history.

[@rsadsultanov3071]

Yes

[@teucerceoofgenshincreative8019]

:( u didnt even show where u get those value behind the cost, are u sure this is legit?

[@YongWang]

Ruina, this is just a numerical example. we assume those cost values are already collected before we start to build the model
