Coevolution of digitalisation, organisations and Product Development Cycle

Over the past 70 years, product design has undergone many important changes due to the impact of contemporary digital technologies (i.e. digital design). To support digital design and information flow throughout the product lifecycle, the digital…

Influence of the CNC behaviour on the laser spot trajectory in LPBF process

The quality of the parts produced in additive manufacturing by laser powder bed fusion (LPBF) depends on the understanding of all the physics involved in the process. In LPBF, the effective path of the laser spot is rarely studied and existing works…

Costs analysis of stealthy attacks with bounded output synchronized Petri nets

This paper concerns the security analysis of discrete event systems modeled with a particular class of synchronized Petri nets that include output functions, called Output Synchonized Petri nets. Such a formalism is suitable and tractable to…

A flash-based thermal simulation of scanning paths in LPBF additive manufacturing

During manufacturing by Laser Powder Bed Fusion (LPBF), the laser-scanning path influences the thermomechanical behavior of parts. Therefore, it is necessary to validate the path generation considering the thermal behavior induced by this process to…

Min-Plus realizable control design for partially observable timed event graphs under marking constraints.

This paper deals with a control problem of discrete event systems subject to capacity constraints. Combined use of timed event graphs and Min-Plus algebra is a well-known approach and efficient for handling timed behavior and mathematical modelling…
