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.

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!

@joshemman Жыл бұрын

You're very correct. The cost should be added to the objective function as well.

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

@joshemman Жыл бұрын

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

Good video One question, do the constraints cover supplier, demand, and transshipment?

@joshemman Жыл бұрын

Yes

@siddhantsingh275 9 ай бұрын

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

@joshemman 9 ай бұрын

Any of those two will work. They will produce the same result.

@akinbodeolubunmi5010 9 ай бұрын

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?

@joshemman 9 ай бұрын

@@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 7 ай бұрын

Than you have to define variables for each product type.

@oxygenabuser5446 7 ай бұрын

@@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😁)
