| Abstract(in English) | The paper proposes a heuristic algorithm RADQ^* for the Maximum Legal Firing Sequence problem of Petri nets (MAX LFS for short) and evaluates it experimentally. RADQ^* is improved from the existing one FSDC for MAX LFS by focusing on extended quasi-bottlenecks, and by repeatedly executing the procedures DEADLOCK-COMP, QUASI_BOTTLENECK and EX-QUASI_BOTTLENECK. As experimental evaluation, RADQ^* (k = 2) is applied to 1000 test problems to each of which existence of an exact solution is guaranteed, and it has produced an optimum solution to each of 770(77.0%) test problems, showing about 11% improvement from FSDC. |
