In this video, we'll talk about how to formulate a special type of LP problems with wide real-world applications. It's called the transportation problem. This type of problems can be solved using the traditional simplex method. However, due to their special structure, there exist specialized algorithms that are much more efficient to solve them.

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

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

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.

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

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

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

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

Is 830 the answer for this example?

How do you get the penalty when supply less than demand
@YongWang 5 жыл бұрын
we assume these penalties are known in this example. in real-world applications, you must estimate these numbers first

Why there is no penalty for unused cost??
@YongWang 5 жыл бұрын
Then you can set those penalties to zero

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

:( u didnt even show where u get those value behind the cost, are u sure this is legit?
@YongWang 5 жыл бұрын
Ruina, this is just a numerical example. we assume those cost values are already collected before we start to build the model
