Detection of time shift failures in (max, +)-linear systems with time intervals applied to the supervision of assembly lines
Claire Paya, Euriell Le Corronc, Yannick Pencolé · 2019
In this paper, we address the problem of failure detection in assembly lines modeled as Timed Event Graphs (TEG). The proposed method represents TEGs as (max,+)linear systems with time intervals and aims at detecting time shift failures in the underlying assembly lines. To do so, we propose the definition of a set of indicators relying on the residuation theory on (max,+) linear systems that handle certain and uncertain observable outputs.
