In this paper, the authors wish to discuss the knowledge involved in the design process and methods to represent it into computer aiding systems. In particular, knowledge based engineering systems and their functioning logic are inspected. This is in order to clarify the evolutionary path of the systems and understand a possible further evolution. The paper is subdivided into four main sections where at first a distinction of data, information and knowledge and the state of the art of knowledge classification are reported; then, the level of knowledge representation in aiding systems pointing out a basic distinction between algorithmic systems and object oriented systems is presented. Finally a practical example based on the design of a sheetmetal press brake machine is reported.

Abstract
In this paper, the authors wish to discuss the knowledge involved in the design process and methods to represent it into computer aiding systems. In particular, knowledge based engineering systems and their functioning logic are inspected. This is in order to clarify the evolutionary path of the systems and understand a possible further evolution. The paper is subdivided into four main sections where at first a distinction of data, information and knowledge and the state of the art of knowledge classification are reported; then, the level of knowledge representation in aiding systems pointing out a basic distinction between algorithmic systems and object oriented systems is presented. Finally a practical example based on the design of a sheetmetal press brake machine is reported.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
