摘　　要：Petri网是一个功能强大的建模工具,已广泛应用于业务流程的建模与分析,但是原型Petri网对业务流程的成本分析却无能为力。首先介绍原型Petri网的定义,然后针对实际业务流程建模中成本预算分析的需要,对原型Petri网扩展价格因素,定义了价格Petri网及其变迁触发规则,而后定义了计价状态空间的概念,并给出计价状态可达空间的构造算法,最后通过一个例子说明价格Petri网可以有效地对业务流程进行成本分析。Petri net is a powerful modeling tool which is widely used in modeling and analysis of business processes, but prototype Petri nets are not appropriate for cost analysis. Firstly, the definition of prototype Petri nets is given, then for the need of cost analysis of actu- al business processes, this paper proposes Price Petri nets by extending the prototype Petri nets with price factor, and Price -state - space is defined, then a algorithm is given to construct the Price - state - space of Price Petri nets , finally, this paper gives an example and draws a conclusion that Price Petri nets can effectively analysis the cost of business process.
