I'm taking a Graduate Quantitative Analysis class, and I'm filled with gratitude that I found your channel. You present your material with such clarity and it's so easy to understand. Thank you so much! Sending blessings from Upstate New York ⭐️🙏🌞
I came here to take a screenshot of the diagram for a presentation. But i have to say, this is by far the most useful videos on this topic I've ever seen.
Not gonna lie, I really love your videos!!! Personally, you are probably the best math teacher I know in the world. Thank you so much for uploading these videos, we appreciate it, sir!!!🙏
Quick Question: In the video @5:03 --> when you add a connection between node 3 & node 6 to ship certain demand and add that to the constraints, shoudn't you add X36(units shipped form 3 to 6) * unit cost of shipping from node 3 to node 6 in the objective function as well? Thanks for the amazing explanations!
Thanks so much for this.. please what do we do in a case where we have to ship from warehouse 4 and 5 to warehouse 4 and 5 before shipping to the final destination
In the capacitated routes section, if it is written that no more than 40,000 units can be moved each week through node 4? Will the constraint be the same as X14+X24+X34
Will the constraint of x14+x24+x34-x46-x47-x48 be totally ignored and then replaced with either of the one @siddhantsingh275 mentioned if it is written that no more than 40,000 units can be moved each week through node 4 ? or will either of the constraints @siddhantsingh275 mentioned be inputted along with x14+x24+x34-x46-x47-x48?
@@akinbodeolubunmi5010 If a node is truly a transshipment node, then it must give up whatever it receives; it can’t keep any. Thus, you must still include x14+x24+x34-x46-x47-x48=0.
@joshemman what if the plants manufactured different types of products and every delivery zone had different demand for each product? how can i formulate that?
@@joshemman Thank you for the quick reply really appreciate it. But I still can't figure it out.Perhaps I didn't state my question clearly. Lets say that we have Plant A making product A, Plant B making product B and Plant C making product C. There are 3 warehouses and 3 Delivery Zones and Each Delivery Zone demands a certain amount of each product and the supply is equal to demand. In this case do I need to consider a different solving method (some new constraints maybe) or can I apply the things you do in your video without making any changes? I'm really not getting the difference between having a single product in different plants and having different products in each plant. (sorry for the long question😁)

Thanks so much, Claudia, for taking time to make this generous donation.
That kind gesture means a lot to me.
Much appreciated.

You're very correct. The cost should be added to the objective function as well.
Very Crisp and well explained!!
Save time in my life best🎉❤
I hope i found your videos earlier in the semester, but I'll crush the finals!
Thank you, sir! Very helpful.
This was really helpful , Thank you😭😭😭😭😭😭😭😭🙏🙏🙏🙏🙏🙏
Thanks so much for this.. please what do we do in a case where we have to ship from warehouse 4 and 5 to warehouse 4 and 5 before shipping to the final destination
If node 4 can ship to node 5, and node 4 can ship to node 5:
then for node 4,
X14 + X24 + X34 + X54 = X45 + X46 + X47 + X48
and for node 5,
X15 + X25 + X35 + X45 = X54 + X56 + X57 + X58

Hello sir
I like your work.
Which software do you use to make these videos..
Thanks
I designed it in Powepoint and edited in Camtasia Studio.
Thank you
Can you please help me out with which transport route will cost least and which cost most per trip
Cost least: Minimize
Cost most: Maximize
You talking about over all cost ...can you please help me out for per trip...single route which cost more or which cost less
@@hussainshaikh5992 Do you have distance information as well?
clear explanation thanks.

Any of those two will work. They will produce the same result.
Will the constraint of x14+x24+x34-x46-x47-x48 be totally ignored and then replaced with either of the one @siddhantsingh275 mentioned if it is written that no more than 40,000 units can be moved each week through node 4 ? or will either of the constraints @siddhantsingh275 mentioned be inputted along with x14+x24+x34-x46-x47-x48?

Good video
One question, do the constraints cover supplier, demand, and transshipment?
Yes
Thanks for this great video
You're welcome Gg
Thank you.
Thank you so much!
love the video, could you make one solving it through excel solver? thank you
Sure. I will work on that.

@joshemman what if the plants manufactured different types of products and every delivery zone had different demand for each product? how can i formulate that?
Than you have to define variables for each product type.

@@oxygenabuser5446 Something like …
Plant: A, B, C
Warehouses: U, V, W
Delivery Zones: D, E, F
Plants:
AU + AV + AW = A’s Supply
BU + BV + BW = B’s Supply
CU + CV + CW = C’s Supply
Warehouse U:
AUD + AUE + AUF = AU
BUD + BUE + BUF = BU
CUD + CUE + CUF = CU
Similarly for V and W
Delivery Zone D:
AUD + AVD + AWD = A required at D
BUD + BVD + BWD = B required at D
CUD + CVD + CWD = C required at D
Similarly for E and F.
Very explicit
Thanks!
Thanks, Mo. I really appreciate the kind gesture.
Nice
