Hi, I am an application developer and need to create a computer application which output should be the best possible combination of orders that would fit in a a metal stick. I have tried by sorting the order qty in descending order, but found that this approach was very simplistic. I need to know if there is any Math model or formula to make this calculation. Example of what I need to accomplish: I have a metal sticks of 2100 MM (Stick are always the same length) The orders could be of different lengths: 1210 MM 860 " 320 " 650 " 540 " The goal is to cut the orders using the 2100 MM stick by scrapping the list qty of material. In this case the ideal recomendation would be: STICK LENGTH: 2,100 MM =========================================== To cut the stick like this: One order: 1,210 MM & One order: 860 MM Total qty used: 2,070 MM Scrap Qty: 30 MM Someone recomended me to use the Monte Carlo simulation, but I found that this will not work for this scenario. Someone else told me this would be a combinatory analysis, but I am not sure either of this one. I hope you can point me to the right direction. Thanks, Roddy.
