Hello Sir,
I can send you a file where you can enter your stock length and your pieces lengths and run the program to obtain your optimal quantities to minimize waste.
Here are some results with the example you provided:
-Type A: 1 * 1600 mm, 0 * 1200 mm, 2 * 1800 mm ; 0 mm wasted
-Type B: 2 * 580 mm, 2 * 1800 mm ; 340 mm wasted
-Type C (with same piece sizes as type A): 3 * 1200 mm, 1 * 1800 mm ; 100 mm wasted
Best regards,
Benoit Spiess
