EU-MATHS-IN: MATHEMATICS FOR INDUSTRY IN EUROPE (MS-66)
We will show how a method is derived and applied to the case of a tanker berthing at the liquid
jetty in the port of Koper. The results will discuss the dynamics of a coupled system.
Suboptimal scheduling of a fleet of AGVs to serve online requests

In the talk we consider an online problem in which a fleet of vehicles must serve transportation
requests arriving over time. We propose a dynamic scheduling strategy, which continuously
updates the running schedule each time a new request arrives, or a vehicle completes a request.
The vehicles move on the edges of a mixed graph modeling the transportation network of a
workshop. Our strategy is complete in the sense that deadlock avoidence is guaranteed, and
all requests get served. The primary objective is to minimize the total tardiness of serving the
requests, and the secondary objective is to minimize the total distance traveled. We provide
qualitative results and a comparison to another complete strategy from the literature. The main
novelty of our approach is that we optimize the schedule to get better results, and we measure
solution quality which is very rare in the AGV literature.
Overview of HU-MATHS-IN, the Hungarian Service Network of
Mathematics for Industry and Innovation

Inspired by the creation of EU-MATHS-IN, HU-MATHS-IN was established in 2013. Initially,
the activities of the Hungarian network were based on the decades-long industrial collaborations
of the national mathematical research groups. Since 2017 its activities are intensified by an EU
and Hungary-supported project (EFOP 3.6.2-16-2017-00015) in which best practices of the EU-
MATHS-IN national networks were analysed and some of them adapted. The main results of
the project include, among others, the following ones:
• more than 50 short-term aimed basic research projects with industry,
• two collaborative projects of the HU-MATHS-IN research groups,
• national one-stop-shop for services to industry with mathematical technologies.
HU-MATHS-IN has been participating in the EU-MATHS-IN activities strongly, e.g. with
succesfull research and innovation actions projects within the H2020 framework program.
In this talk an overview of the organization of the network and its activities will be given.
In addition, some short-term industrial projects of HU-MATHS-IN will be overviewed from
the fields of computational acoustics and model order reduction for compressible fluids, with
mathematical details.
