Product modeling method based on behavior flow spatial sequence coloring Petri network

Abstract

The invention provides a product modeling method based on a behavior flow spatial sequence coloring Petri network. The method at least comprises the following steps of: I, encoding parts related to a product and connecting relations among the parts; II, establishing a semantic network of a behavior flow spatial sequence in the product on the basis of the encoding; III, establishing a behavior flow spatial connecting relation predicate matrix on the basis of the establishment of the semantic network for expressing the connecting relations among product structural units, wherein rows and columns are structural unit codes related to the product parts, and data in the matrix are connecting relation codes; and IV, converting the behavior flow spatial connecting relation predicate matrix into a coloring Petri network model of a spatial sequence. A more intelligent behavior flow product modeling method is adopted, and display expression of flow is performed through the establishment of the semantic network of the behavior flow spatial sequence and Petri network modeling, so that a transmitting sequence of a spatial structure state in a behavior flow modeling process is obtained.

Description

technical field [0001] The invention relates to the field of product modeling, in particular to a product modeling method based on behavior flow space sequence coloring Petri net. Background technique [0002] Complex products refer to a class of products with complex structures, intensive technology, high manufacturing requirements and costs, complex process management, and changing customer needs. The conceptual design is the core stage of the complex product design process and the fundamental link to enhance product competitiveness. Statistics show that the conceptual design stage, which accounts for only 5% of the cost, determines 85% of the product life cycle cost, and more than 70% of the product design quality. Time and cost are the key factors that determine the success of a product just like quality. Since conceptual design is in the earliest stage of the product life cycle, it has a great influence on the subsequent design process. Conceptual design fundamentally...

Problems solved by technology

[0005] Although the concept of product behavior flow modeling has been proposed, it has not been analyzed in depth. Therefore, this paper is dedicated to the in-depth study of the expression of behavior flow. This paper proposes the spatial sequence of behavior flow A new concept, from the perspective of the evolution of spatial sequences to describe the intelligent design process of products based on behavioral flow, the subsequent chapters of this paper will propose two expressions of behavioral flow spatial sequences and the conversion principles of these two expressions
