This note suggests faster algorithms for two integrated production/distribution problems studied earlier, improving their complexities from O(n2V + 4) and O(n2(L + V)2) to O(n) and O(n + Vmin {V, n}) respectively, where n is the number of products to be delivered, V is the number of vehicles...

It is now widely recognized that the increase of greenhouse gases in the atmosphere is due to the consumption of fossil fuels since the beginning of the 20th century. In this context, research on new energies and their development on a large scale is a priority. Hydrogen is a potential candidate...

We consider the the two-machine ow-shop serial-batching scheduling problem where the batches have limited size. Two criteria are considered here. The rst criterion is to minimize the number of batches. This criterion re ects situations where processing of any batch induces a xed cost, which...
