Hi,
I want to Creation a algorithm or use existing ??

I have
customer 1
customer 2
customer 3

order of customer 1

Item quantity
item1 10
item2 2
item3 3

Vendor1 Amount on order

Item quantity cost total min-deliver
item1 10 50 500 100
item2 2 40 80
item3 3 40 120

Vendor2 Amount on order
Item quantity cost total min-deliver
item1 10 60 600 50
item2 2 30 60
item3 3 50 150

Vendor3 Amount on order
Item quantity cost total min-deliver
item1 10 70 700 200
item2 2 50 100
item3 3 30 90


From above we see that
for

item1 vendor1 has low cost 500 and min-deliver 100
so we give it to vendor1

item2 give it to vendor2

item3 vendor1 total 120 and min-deliver 100
vendor3 total 90 and min-deliver 200
So give it to vendor1

For this type of calculation which algorithm is use??
Or how to create it any sample link or sample code please?

Write now i am not starting for coding..
just collecting information...
Is it use to job scheduling or another algorithm to find solution??
