Problems solved by technology

But logical Petri nets lack the ability of fuzzy reasoning. Fuzzy Petri nets use production rules for reasoning, but they are only used to deal with an uncertain thing or a complete process.

Embodiment Construction

[0109] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0110] 1. Petri net is a mathematical representation of discrete parallel systems. Petri nets were invented by Carl A. Petri in the 1960s and are suitable for describing asynchronous and concurrent computer system models. Petri nets not only have strict mathematical expressions, but also have intuitive graphic expressions, have rich system description means and system behavior analysis techniques, and provide a solid conceptual foundation for computer science. The Petri net model describes the state-behavior technology in the analysis of parallel systems in a natural, intuitive and easy-to-understand manner. It is mainly used in computer protocol models, flexible system models, computer integrated manufacturing, artificial intelligence, system analysis and other fields.

Abstract

The invention discloses a service flow analysis method based on a fuzzy logic Petri network, which belongs to the field of service flow analysis of the fuzzy logic Petri network and comprises the following steps of firstly proposing a fuzzy logic Petri network theory; secondly, modeling the order processing problem of the merchant; according to the reachable graph generation algorithm, making a reachable identification graph of the order processing model based on the fuzzy logic Petri network; and finally, through a forward reasoning algorithm, reasoning to obtain the credibility of each decision of the order processing model based on the fuzzy logic Petri network, obtaining the possibility that the merchant delivers the order, further obtaining the optimal decision of the merchant for processing the order, and achieving the goal of process optimization. The fuzzy logic Petri network not only can perform fuzzy reasoning, but also has the characteristics of batch processing and value transmission uncertainty, and Tokine is used for corresponding to propositions in the modeling process, so that the Petri network has the stronger expressive force, and the complexity of the model is simplified.

Description

technical field [0001] The invention belongs to the field of business process analysis of fuzzy logic Petri nets, and in particular relates to a business process analysis method based on fuzzy logic Petri nets. Background technique [0002] Petri nets are a mathematical representation of discrete parallel systems. Petri nets were invented by Carl A. Petri in the 1960s and are suitable for describing asynchronous and concurrent computer system models. Petri nets not only have strict mathematical expressions, but also have intuitive graphic expressions. They have rich system description methods and system behavior analysis techniques, and provide a solid conceptual foundation for computer science. Compared with other net system models, one of the outstanding advantages of Petri net is that it is easier to describe concurrency and conflict. [0003] Simple Petri net is a model describing the process, which is composed of places, transitions, flow relations, and tokens. With ...
