On How to Not Prove Faulty Controllers Safe in Differential Dynamic Logic

no code implementations12 Jul 2022 Yuvaraj Selvaraj, Jonas Krook, Wolfgang Ahrendt, Martin Fabian

Differential dynamic logic is a formal specification and verification language for hybrid systems, which are mathematical models of cyber-physical systems.

Robust Stutter Bisimulation for Abstraction and Controller Synthesis with Disturbance: Proofs

no code implementations27 May 2022 Jonas Krook, Robi Malik, Sahar Mohajerani, Martin Fabian

This paper presents an algorithm to construct the corresponding robust stutter bisimulation quotient to solve the abstraction problem, and it is shown, by explicit construction, that there exists a controller enforcing a linear temporal logic formula for the original system if and only if a corresponding controller exists for the quotient system.

Formal Development of Safe Automated Driving using Differential Dynamic Logic

1 code implementation14 Apr 2022 Yuvaraj Selvaraj, Wolfgang Ahrendt, Martin Fabian

The challenges in providing convincing arguments for safe and correct behavior of automated driving (AD) systems have so far hindered their widespread commercial deployment.

A Compositional Algorithm for the Conflict-Free Electric Vehicle Routing Problem

no code implementations14 Mar 2022 Sabino Francesco Roselli, Per-Lage Götvall, Martin Fabian, Knut Åkesson

The CF-EVRP involves constraints such as time windows on the delivery to the customers, limited operating range of the vehicles, and limited capacity on the number of vehicles that a road segment can accommodate at the same time.

An SMT Based Compositional Algorithm to Solve a Conflict-Free Electric Vehicle Routing Problem

no code implementations10 Jun 2021 Sabino Francesco Roselli, Martin Fabian, Knut Åkesson

The Vehicle Routing Problem (VRP) is the combinatorial optimization problem of designing routes for vehicles to visit customers in such a fashion that a cost function, typically the number of vehicles, or the total travelled distance is minimized.

Leveraging Conflicting Constraints in Solving Vehicle Routing Problems

no code implementations15 Mar 2021 Sabino Francesco Roselli, Remco Vader, Martin Fabian, Knut Akesson

The Conflict-Free Electric Vehicle Routing Problem (CF-EVRP) is a combinatorial optimization problem of designing routes for vehicles to visit customers such that a cost function, typically the number of vehicles or the total travelled distance, is minimized.

Model Properties for Efficient Synthesis of Nonblocking Modular Supervisors

no code implementations11 Jul 2020 Martijn Goorden, Joanna van de Mortel-Fronczak, Michel Reniers, Martin Fabian, Wan Fokkink, Jacobus Rooda

Supervisory control theory provides means to synthesize supervisors for systems with discrete-event behavior from models of the uncontrolled plant and of the control requirements.
