This video is only 6 minutes and 40 seconds long and yet I learned more from you than I did from my university lecturer. Incredible! Credit to you Joshua! Many thanks.
This Video is uploaded 7 Years back but still, your teaching methodology is way better than that of my professor at the university. Thank you so much for your explanations.
The simplest explanation ever. It covers the fundamentals needed to understand the model, whereas my prof confuses with symbols and no definition/explanation.
Congratulations Joshua for the content and the well-made framework !! Your video is a good example of how difficult explanations could be converted into easy ones...
Thankyou so much dear mentor Joshua your teaching strategy was surprising for me i got everything in this single lecture i was trying to find a lecture to clear my concepts about PL model you are the who helps me to finishing my topic .Thankyou so .Keep growing.
Great explain sir. I was impressed with how clearly you explained it in less than 7 minutes. This is the hard part, now putting this into a solver is the simple part.
Thank you so much.This is so clear and clean.I am struggling hard to solve the transportation problem and this made me feel it's is so easy.thaks a lot for this work you did
My model on my solver proved infeasible for your second solution when demand exceed supply. I used greater than or equal sign for the demand constraints and less than and equal sign for the supply constraints, then I got an optimal solution.
HI,I have a question.Is this one of the types of transportation problem?I mix the methods of the Transportation problem.For example I don't know that what is the difference between Northwest method and This.
Thanks so much for the tutorials. Joshua, I have a couple of questions for you: 1. Do you also have videos for solving Integer Linear Programming problems and showing how it's related to NP-Complete problems? 2. Do you also have videos for solving Linear Programming problems using Simplex approach? Again, thank you for the tutorials.
Fantastic videos Joshua. Thank you. Question: what if demand and supply are always equal (e.g., a package delivery network where all packages must get to their destinations), how might we minimize the cost of collecting the packages from (n) distribution centers and delivering them to (n) cross dock facilities. For bonus points, we have 3 different vehicle sizes (S, M, L) with different operating costs. The DCs have different quantities of packages to deliver to each cross-dock. As a result S sized vehicle may get full before the end of it's run and it may have been more efficient to send a M or L sized vehicle, etc. I'd love your perspective (or anyone here) on how to solve this riddle. Thank you in advance and keep the great videos coming.
Thanks for the great video! How could I use this concept when the cost for each route(eg. 5,6,4,6,3,7 in your video) depends on the amount of item (xij)? I am wondering if the linear programming can be applied for the case where fundamental input data(cost in this case) is subject to change.
Unfortunately, no. The prices in an LP transportation problem must be fixed irrespective of volume. If the prices change with volume, it will no longer be a linear program.
@@joshemman Thanks for your kind reply. What model or method can I use for non-linear example? If there is one, It would be greatly appreciated if you can let me know the specific name of it with any kind of example.
@@강인수-t9n Non-linear programs (NLPs) are similar to linear programs in that they both contain algebraic functions and inequalities. The only difference is that linear programs contain only linear expressions such that if X and Y are decision variables, then XY or X^2 are invalid. In your case, if X = quantity and Y = Price, then total price XY is nonlinear. You can then solve it in Excel’s Solver by using the GRG Nonlinear method.

It's just 6:40 minutes but it covers all the information I need. Love this. Thank you so much
The simplest explanation ever. It covers the fundamentals needed to understand the model, whereas my prof confuses with symbols and no definition/explanation.
I went through 4 hours of slides from my university lectures and then I found your video. THANK YOU!!!!
You helped me pass my class with an A+. Thank you so much!!
Brooooo!!!!!!. How are you this good? In 6 minutes I've covered a good section of a course. My lecturers don't come close.Keep up the good work!
Thank you so much for summarising a 1 hour lecture so beautifully in a 6 minute video! Best explanation in the simplest way possible!
Wow, you are the best. I got an A on my exam thanks to your fantastic explanations. I need another A for my final. Thank you sooo much!!
WOW, this video was so clear and concise that it made me feel stupid for ever struggling with this at all. You are a great teacher. Instant sub.
You just saved my life. Thank you for the simplified and detailed explanation. Look forward to more videos from you!
WOW , just less than a minute in, and I appreciate the clarity of voice and explanations!!!!! Well done
Joshua - thanks so much for this, and for all your superb videos. You explain so clearly and it's incredibly helpful.
wish my professor explains like this
Wish my professor even explain anything rather than talk about his life.
me too hhaha !! my professor took 3 hours to explain this and I still didnt get it. this video saved me.
Mr Joshua you are a life saver God bless you my African brother !!!!
Super helpful, thanks!!!!! Beats my hours long online lectures that im paying thousands to attend!
you've covered a lot in less than 7 minutes. Thanks.
GOD BLESS YOU. I have a project proposal due in 2 days and now I know exactly how to model the problem. Thank you!

Glad to hear, Mr Globerus. All the best in your course.
I used the Excel Solver using the variables and constraints proposed, looking for the min and it came back with the exact same variables. Great video.
Thanks for posting, really helping me out for finals!
Passed my math modeling final because of this dude.
You are talented in simplifying these topics
Seriously, so clear and concise, thank you so much!
I gotta say, you really saved my time and brain effort. Kudos!
You're saving my life man!!!!
Saaaaaaaame

Simple, Clear and concise. Thank you❤️
You're welcome, Lauren.
Very well done! Concise and objective.
thank you! The professor only gave the solution but no explanation
wow!! this helped me so much in my revision for my exams :D
That was really helpful. Thanks for making such a nice video. Thanks again Sir.
Thank you! I feel a lot better about my upcoming test, thanks to you!
Really Good Stuff. I enjoy all of your videos. Wish my professor broke it down like this
Wow incredible man 👍👍👍👍
as always great explanation brother, thank you!
You're welcome, Aram.
What a expalanation it was very clear wish my teacher will teach like this
Great video! Made everything simple. Keep producing great content!
Great video!!!! Shouldn't the dummy plant have Big M for shipping cost to deter its being assigned?
You're right. It should.
fantastic brother, you explained that beautifully.
Thanks for the smooth presentation, also very informative
mans doing gods work
You're a savior bro!
Thank you so much sir for explaining in such a simple way.
thanks man. if only RUclips gives diplomas, i would not go waste my time in college for dummy certificate.
thank you very much for such clear explanation.
Thank you from a distanced learner bc of quarantine
Explained like a Lion🦁

You make my exam much easier
THANK YOU SIR. IT WAS REALLY VERY HELPFUL TO ME.....
wow............ you are God sent, thank you
Thanks, Joshua. Great explanations.
Thank you so much. This really helped!
very clear and understandable
Thanks so much for the tutorials.
Joshua, I have a couple of questions for you:

Thank you in advance and keep the great videos coming.
You are a star mate!. thank you.
Could you please let me know which method have you used in this video, Northwest, Minimum Cost or Vogel's?
Thanks
Excellent and clear expression,
Thanks. That was definitely worth the time.
If demand is equal to supply then what will be the inequality sign in constraints?
what do we have to do after making equations ?
I subscribed after watching this video!
Me too
You just saved me.... thank you very much
Amazing and simple. Thank you!
Just Excellent !!! Bravo!
you made a great video! Thanks for your effort!

in java which frmula is used
So easy so smooth ,,, thank you
This was incredibly helpful
Interesting video. Can you tell me how you can apply your LP to the Vogel's Approximation Method or the Least Cost Cell method?
Great presentation! Thanks.
Great explanation! Thanks. 👍
If it is a multi model??
Does anyone know where this linear equation was first formulated and by who?
Hey man, it's a great video. Have you made a part 2 and onward? Why don't you complete the whole model and show us the solution to the problem
How do you create the circles in excel?

THANK YOU SO MUCH but i got a question in a case that the demand and the supply is the same in ur case 800 = 800 does it many any difference?
800 = 800 is fine since ≤ includes equality.
