In this paper we consider a single machine scheduling problem with two criteria; minimizing both maximum tardiness and the number of tardy jobs. We present both heuristic and branch-and-bound algorithms to find the schedule which minimizes the number of taedy jobs among all schedules having minimal maximum tardiness. Computational results show thatproblems with up to 40 jobs can be solved in less than one minute of computer time, and soultion difficulty tends to increase as the range of due dates increases relative to the total processing time. We extend our results to ge nerate all nondominated schedules for the two criteria. Computational experiments indicate that all non-dominated solutions to problems with 40 jobs can be generated. However, solution difficculty for these problems is highly dependent on problem parameters. |

This work focused on obtaining fermented oil cake (cotton or Jatropha) via macrofungi growth with potential characteristics for animal feed formulations, such as the presence of extracellular enzymes, bioactive (ergosterol and antioxidants), and detoxification of antinutritional compounds. The concentration of phorbol esters was reduced by four macrofungi in Jatropha seed cake (JSC) to non-toxic levels. At least two macrofungi efficiently degraded free gossypol in cottonseed cake (CSC). Fermentation with Coriolopsis sp. INPA1646 and Tyromyces sp. INPA1696 resulted in increased ergosterol concentrations, antioxidant activity reduction, and high activity of laccases and proteases. Bromatological analysis indicated high crude protein concentrations, with partial solubilization by fungal proteases. Fermented products from Coriolopsis sp. and Tyromyces sp. in JSC or CSC can be considered important biological inputs for monogastric and polygastric animal feed. |
