Embodiment

[0025] Before describing the product behavior flow modeling method, the basic concept of the product behavior flow modeling framework is firstly explained.

[0026] 1. Substance, Behavior and Behavior Flow State in the Behavior Flow Model

[0027] (1) Behavior

[0028] Learn from the understanding of the behavior of the FBS model, and at the same time use the ontology point of view to look at the behavior. First of all, it is considered that behavior is objective, which is an objective description of the objective effect achieved by the product. We adopt a device ontology concept to describe behavior, which is extended to system engineering ontology and component-oriented ontology. The device ontology specifies a device-centric point of view to look at products, thinking that any product or component is a component of a device, and the device processes the input and produces the output we need. We call the process of changing the substance from the entrance to the exit of t...

Abstract

The invention discloses a product behavior flow modeling method based on a hybrid Petri network. The method is characterized by including: in the horizontal direction, mapping objective behaviors to subjective functional areas to build functional models which fit with human cognition, and converting from objective behavior models to behavior realizing-structure models to realize specific products; and in the vertical direction including at least two levels, starting from a single abstract behavior which is capable of realizing conversion from an initiate state to a target state from the top level, and finishing at that each behavior at the bottom layer directly corresponds to one simple realizing structure. Product behavior flow models are built through product behaviors, an accurate mathematic model representation is provided, a novel thought is provided for computer application of mathematical modeling, and universality and practicality of product modeling are improved.

Description

technical field [0001] The invention relates to product modeling technology, in particular to a product behavior flow modeling method based on mixed Petri net. Background technique [0002] Product design is a complex mental work that requires the comprehensive application of various experiences and professional knowledge. It is a process of analysis, synthesis, and reasoning. Traditional CAD systems cannot reflect this kind of intelligence. The goal of ICAD is to make computers participate in design activities as much as possible, and use the knowledge, experience, and data of design experts to complete product design tasks such as program decision-making, structural design, performance analysis, and graphics processing. The salient feature of ICAD is that it has a knowledge base to solve product design problems, and has a reasoning and decision-making mechanism for selecting knowledge and coordinating engineering database and graphics library to complete design tasks. Sin...
