摘要
以连续Petri网概念为基础,引入带弧权和禁止弧的扩展连续Petri网,将扩展连续Petri网作为工具对随机数生成器进行研究。选用随机数学中的乘同余法产生服从[0,1]均匀分布的随机变量,从而解决Petri网的规模因随机变量的精度增加而急剧增大的问题,针对某些逆变换法无法实现的分布,引入拒绝法,对现有的随机数发生器Petri网模型进行改进。
On basis of concepts of continuous Petri nets, an expanded continuous Petri nets with inhibitor arcs and variables of arcs weight is introduced. A deeply research is made on random number generator with continuous Petri nets as a tool. The random variables in range between 0 and 1 is generated with multiplicative congruential method of random maths, and the problem of increasing number of Petri nets with precise random number is settled. A denial method to work out the problem which the inverse transformation does not work with is introduced. The improvement of simulation of random number generator with Petri nets is made.
