The 14th International Workshop on Discrete Event Systems (WODES 2018) was held May 30– June 1, 2018, at the Towers Hotel Stabiae Sorrento Coast located on Sorrento Coast in Italy. The aim of WODES is to join researchers interested in Discrete Event Systems (DESs) field from all over the world to exchange information about their activities on formalisms, methodologies, tools and applications. The Workshop series started in Prague (1992). Since then, the following thirteen previous workshops were held every two years: Antibes (1994), Edinburgh (1996), Cagliari (1998), Ghent (2000), Zaragoza (2002), Reims (2004), Ann Arbor, Michigan (2006), Goteborg (2008), Berlin (2010), Guadalajara (2012), Cachan (2014), and Xi’an (2016). Twenty years after the one held in Cagliari, WODES’18 is the second one in the series held in Italy. A logo inspired to the view of Naples from Sorrento Coast was designed for WODES 2018. A call was issued for the logo design, the winner was Andrea Albinni. The volcano Vesuvio, the sun and the sea are represented in the logo.

WODES’18 (see http://wodes2018.unisa.it/) was sponsored by IFAC, the International Federation of Automatic Control, and was co-sponsored by IEEE Control Systems Society and by IEEE Italy Section, Italian Chapter IEEE Robotics and Automation, Italian Chapter IEEE Control Systems. It was locally organized by the Automatic Control Group of the Dipartimento di Ingegneria dell’informazione ed elettrica e Matematica applicata of Salerno University. For the first time in WODES history, the workshop was preceded by the 1st International school on Discrete Event Systems (http://schooldes2018.unisa.it/). The goal of this 3 day pre-conference event was to introduce the relevant areas and formalisms of DES (control, modeling, diagnosis, optimization, Petri nets, automata) in a series of 2-hours lectures. The event was a challenge, but turned out to be a success with 44 registrations from all over the world (29 attendees from Europe, 6 from China, 4 from USA & Canada, 3 from Brazil, 1 from Tunisia, 1 from Singapore).

 

Technical Program

WODES 2018 received 106 submissions, and each one was peer reviewed by three reviewers. Among all submissions, 76 papers were accepted and included in the proceedings that will be published on the open-access IFAC-PapersOnLine series hosted on ScienceDirect (http://www.sciencedirect.com). More than 130 people attended the opening session in the morning of May 30, 2018. The corresponding authors of the 76 accepted papers came from 18 countries, with the following distribution: 46 papers come from Europe (which represents about the 60.5% of the total), 10 from Latin America, 10 from Asia, 7 from US/Canada, 2 from Oceania, and 1 from Africa.

The program included three excellent plenary talks. Indeed, the workshop opened on Wednesday 30 May 2018 by the talk titled “The Science of Software and System Design”, by Prof. Stavros Tripakis. On May 31, Prof. Spyros Reveliotis gave his talk titled “Logical Control of Complex Resource Allocation Systems”. Finally, Prof. Carla Seatzu gave her plenary talk titled “Partially observed discrete-event systems: from state estimation to intrusion detection”. In addition to these plenary speeches, there were 71 oral presentations in nine regular and five invited sessions. All the papers in the special sessions went through the normal reviewing process.

Organisers and topics were:

  • Kai Cai and Eric Rutten, “Applications of Discrete-Event Systems” (I & II).
  • Jan Komeda,“(Max, +)-Algebra and Quantitative Issues in Discrete Event Systems”.
  • Dimitri Lefebvre, Pascal Marange and Gonzalo Mejia, “Modelling and Control with Discrete Event Systems for Scheduling Problems”
  • Maria Pia Fanti and Agostino Marcello Mangini, “Observability, Opacity and Liveness in Discrete Event Systems”

 

Demonstrator session

For the first time, a demonstrator session was organized to provide an opportunity for promoting research or educational-oriented devices, innovative prototypes and attractive transfer of technologies towards high-tech enterprise. The session, organized by Prof. Maria Grazia Dotoli and Christian Mahulea, received 5 contributions.

 

Awards and Social program

The Best Student Paper Award ceremony: prof. J.J. Lesage and Yingying Liu (winner)

The Best Student Paper Award, which was established at WODES 2012, recognizes excellence in a WODES conference paper whose primary author is a student. The award committee, chaired by Prof. Jean-Jacques Lesage, selected five finalists, and the winner of the WODES 2018 Best Student Paper Award was Yingying Liu for the paper “On Scalable Supervisory Control of Multi-Agent Discrete-Event Systems”. An interesting social program was offered to participants. In addition to the welcoming reception, a walking visit to the beautiful town of Sorrento, and a guided tour to Pompeii’s ruins, the conference organized a gala dinner on the last evening in a fine restaurant in Vico Equence, a beautiful town on Sorrento Coast.

 

Concluding Remarks

Prof Antonio Ramirez Trevino inviting the audience to Wodes 2020 in Brazil

During the closing ceremony Prof. Joerg Raisch, incumbent chair of the WODES steering committee, introduced his successor Prof. Antonio Ramirez Trevino, who announced the future conference. The 15th WODES will be held in 2020 in Brazil. We wish ever-increasing success to future WODES events. There were 6 members of Salerno University working in the local organization and 2 volunteers. We would like to give a big thanks to them all for the organization of an enjoyable and successful workshop.
