Transportation Problem - LP Formulation

[@FTK2010]

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.

[@keriliusleslie8977]

Quite literally!

[@abramswee]

same here!

True, my lecture is going on and i am listening to this.

[@ye4us]

Explained in a 6minute video that took my Lecturer a whole week. Thanks

[@AldosWorldTV]

10/10 explanation, very simple clear voice love it

[@f4rhan_179]

AldosWorld TV lmao

[@vinayhirve6459]

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.

[@Danny-ex3tj]

The simplest explanation ever. It covers the fundamentals needed to understand the model, whereas my prof confuses with symbols and no definition/explanation.

[@natanielataseven7844]

I went through 4 hours of slides from my university lectures and then I found your video. THANK YOU!!!!

[@khanhhuyentran1323]

It's just 6:40 minutes but it covers all the information I need. Love this. Thank you so much

[@adnanesra1]

wish my professor explains like this

[@turboyess5208]

Wish my professor even explain anything rather than talk about his life.

[@ninabanana5802]

me too hhaha !! my professor took 3 hours to explain this and I still didnt get it. this video saved me.

[@tboogie5775]

You helped me pass my class with an A+. Thank you so much!!

[@New_Genesis_dev]

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!

[@camilaparola2781]

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!!

[@Somalinomad416]

Mr Joshua you are a life saver God bless you my African brother !!!!

[@Jmazz25]

Passed my math modeling final because of this dude.

[@ritujatripathi3075]

Thank you so much for summarising a 1 hour lecture so beautifully in a 6 minute video! Best explanation in the simplest way possible!

[@chinasaikelu2958]

You just saved my life. Thank you for the simplified and detailed explanation. Look forward to more videos from you!

[@okiedokie1875]

GOD BLESS YOU. I have a project proposal due in 2 days and now I know exactly how to model the problem. Thank you!

[@maticulex5713]

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.

[@saintmearl8518]

you've covered a lot in less than 7 minutes. Thanks.

[@CaseyFogarty]

Super helpful, thanks!!!!! Beats my hours long online lectures that im paying thousands to attend!

[@aidanbreen1723]

Thanks for posting, really helping me out for finals!

[@emekaoputa4963]

WOW , just less than a minute in, and I appreciate the clarity of voice and explanations!!!!! Well done

[@claughlin]

Joshua - thanks so much for this, and for all your superb videos. You explain so clearly and it's incredibly helpful.

[@mnjrupp]

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.

[@exiledknight6850]

You are talented in simplifying these topics

[@sial78617]

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.

[@joshemman]

Glad to hear, Mr Globerus. All the best in your course.

[@alexiafoley3448]

Seriously, so clear and concise, thank you so much!

[@jasoncysiu]

Simple, clear, and concise. Thanks, Joshua!

[@Mase2805]

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...

[@slash12387]

You're saving my life man!!!!

[@ramesaed3880]

Saaaaaaaame

[@ivanasaraber2095]

Like your explanation!!! Makes me understand the concept in just 6.40 minutes.

[@khaledqaraman]

Your explanation is just amazing 👍I wish you were my professor... Thanks a lot brother

[@TheProcessMan]

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.

[@johnahn7323]

I wish you're my professor.. You will be the best professor of the course.. My prof sucks..

[@deliavasquez1512]

BEST VIDEO EVER! It made it so simple to understand.

[@joshemman]

Glad it helped!

[@delphinedemeulenaere7090]

thank you! The professor only gave the solution but no explanation

[@jewelsantiago8849]

I gotta say, you really saved my time and brain effort. Kudos!

[@ZaneKumar-km3uf]

Very clear explanation with good visuals. Liked

[@joshemman]

Thanks for liking

[@Kakumark]

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

[@draculina97]

Thank you! I feel a lot better about my upcoming test, thanks to you!

[@laurenpraiz]

Simple, Clear and concise. Thank you❤️

[@joshemman]

You're welcome, Lauren.

[@sjyotihembrom8767]

You are a saviour, Joshua

[@kulskirt]

thanks man. if only KZbin gives diplomas, i would not go waste my time in college for dummy certificate.

[@akinkayode6557]

You made it as simple as possible. you are good!!!

[@pmbees7454]

Wow incredible man 👍👍👍👍

[@DP-yg4pu]

Hi Joshua..I must say you are doing fabulous job

[@meandmynibbas2599]

mans doing gods work

[@nyahhbinghi]

Great video!!!! Shouldn't the dummy plant have Big M for shipping cost to deter its being assigned?

[@joshemman]

You're right. It should.

[@OG_Chaleb]

Explained like a Lion🦁

[@AeroscopeAviation]

Very well done! Concise and objective.

[@BoonyanitSittiphan]

Thank you so much! This video help me to pass the test 😊

[@peace58489]

Amazing video! Saving me for my midterm coming up!! You are the best!! You helped me for stats too!! Cheers man, thank you!!

[@chelvaravi2506]

What a expalanation it was very clear wish my teacher will teach like this

[@learner718]

Thank you so much sir for explaining in such a simple way.

[@aaaengineering8892]

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.

[@jilljoestar5925]

Thank you from a distanced learner bc of quarantine

[@hassanalianees5530]

That was really helpful. Thanks for making such a nice video. Thanks again Sir.

[@LiveTheWeekend]

Really Good Stuff. I enjoy all of your videos. Wish my professor broke it down like this

[@vicvivixchan373]

wow!! this helped me so much in my revision for my exams :D

[@abramswee]

thank you very much for such clear explanation.

[@patelkishann]

THANK YOU SIR. IT WAS REALLY VERY HELPFUL TO ME.....

[@Ali68g]

Thanks for the smooth presentation, also very informative

[@tyronewallace6167]

fantastic brother, you explained that beautifully.

[@kingsleyudeh6043]

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.

[@joshemman]

+Kingsley Udeh Sorry I don't have videos for those. My students only learn LP at introductory level.

[@kingsleyudeh6043]

+Joshua Emmanuel Okay, thanks, Joshua

[@mannysingh2133]

[@rlabatt]

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.

[@aramh3376]

as always great explanation brother, thank you!

[@joshemman]

You're welcome, Aram.

[@dgfcl56ify]

wow............ you are God sent, thank you

[@ch0po54]

Amazing and simple. Thank you!

[@강인수-t9n]

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.

[@joshemman]

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.

[@강인수-t9n]

@@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.

[@joshemman]

@@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.

[@h_githma]

Thank you so much. This really helped!

[@paintgirl1442]

Interesting video. Can you tell me how you can apply your LP to the Vogel's Approximation Method or the Least Cost Cell method?

[@JadyGrudd]

Thanks. That was definitely worth the time.

[@aliguzel8463]

Just Excellent !!! Bravo!

[@rsadsultanov3071]

Could you please let me know which method have you used in this video, Northwest, Minimum Cost or Vogel's? Thanks

[@belinaeasdown8987]

Thank you for the video Joshua

[@thobiemapoulo7920]

Incredible 👌🏾 thank you 😊

[@arunendrachakraborty1332]

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

usually I'm not leaving comments in KZbin videos. But, you really worth likes, share & subscribe. 👍 great explanation; thanks man

[@fidanmuradova7306]

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.

[@svitlanapshenychna2156]

Perfect. Thanks

[@joshemman]

My pleasure Svitlana

[@mohammedalmashibi1727]

So easy so smooth ,,, thank you

[@Zen_Math]

Great presentation! Thanks.

[@MrMando-dk1vr]

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?

[@joshemman]

800 = 800 is fine since ≤ includes equality.
