摘要 S-不变量是进行Petri网结构性质分析的重要工具,但S-不变量的求取尚无有效算法。作者在S-不变量的极小支集的判定、极小支集上S-不变量的求取等方面创新性地提出了一些多项式解决算法。将在上述工作的基础上,结合枚举思想给出一个求取S-不变量基的算法,并提出一些筛选规则以提高枚举的性能。 S-invariant is an important tool for the structual property analysis of Petri nets.Unfortunately there is no effective algorithm for the computation of S-invariants.Several polynomial algorithms were put forward to determine the minimal support of S-invariants and a concrete S-invariants supported by a given minimal S-invariant Support was computed.Based on the above work,combined with enumeration method,a new algorithm for the computation of S-invariants generators was proposed.Furthermore some sieve rules were provided to improve the performance of enumeration.
