known to be NP-hard, heuristics have become a main research interest. Unfortunately, there has not been done much research …

feasible solutions as well. Hence, we also have two optimization guided heuristics. A computational study consisting of a set …

, two heuristics are presented. One heuristic is based on the result of the column generation procedura while the other is …

. Priority rule-based methods still constitute the most important class of these heuristics. Of these, in turn, parameterized … their effectiveness considerably. We extend this approach by integrating heuristics and case-based reasoning (CBR), an … performance similar or close to state-of-the-art heuristics. In addition, the analysis undertaken provides new insight into the …

heuristics do better. In priority rule-based scheduling, attempts to remedy this have been made by combining simple priority …
