Just in time vs. all in sync: an analysis of two types of synchronization in a minimal model of machine activity in industrial production based on excitable dynamics on graphs — •Sanghita Bose1, Annick Lesne2,3, Julia Arlinghaus4, and Marc-Thorsten Hütt1 — 1Department of Life Sciences and Chemistry, Jacobs University Bremen, Germany — 2Institut de Génétique Moléculaire de Montpellier, University of Montpellier, CNRS, F-34293, Montpellier, France — 3Sorbonne Université, CNRS, Laboratoire de Physique Théorique de la Matière Condensée, LPTMC, F-75252, Paris, France — 4Otto-von-Guericke University Magdeburg, Universitätsplatz 2, 31904, Magdeburg, Germany.
The notion of synchronization in logistics is distinct from that encountered in the natural sciences, and in particular, in physics. In logistics, synchronization is often associated with a 'just in time' paradigm in supply and production systems. A perfect synchronization therefore is that the arrival (of goods at a warehouse or parts at a machine) is a cue for a subsequent transportation or manufacturing event. Globally, this type of synchronization can be envisioned as a wave of activity running through a distribution network or a production network. Here our goal is a deeper theoretical understanding of these two types of synchronization, the one from logistics and the one from physics, as well as their interplay in the context of production systems. We employ a minimal model of propagating excitations (representing machine activity) in a graph (representing a production network).
