The representation of conceptual product based on component-connector design feature with P/T net approach

Abstract

In this paper, the entity-connector and non-entityconnector of design feature are defined and the connector is divided into two classes. The P/T net-based hierarchy structure model of the component-connector design feature and the energy flowing P/T net model of the primitive mechanism are built up. The product model is mathematically described from the perspectives of the function, design feature, attribute and their relationships. Then the P/T net-based hierarchy structural model is applied to represent the conceptual product, and the energy flowing P/T net is established to simulate the working status of the conceptual product.

A grammar approach for combining product configuration modelling with behavioural aspects and simulations

“…A compound designed object can be represented by a set of features and can be completed by some other ones, which supply an appropriate approach for design representation [45]. There are different definitions of features.…”

“…Csabai et al [52] consider a connection feature as a form feature that is attached to an interface feature of a design space. Guangming et al [45] view a connector feature both as a functional element and a design feature during the conceptual design phase. Based on properties 1 and 2, primitive and non-primitive structures possess two sets of configuration features: tie configuration features and joint configuration features.…”
