Tropical Abstractions of Max-Plus-Linear Systems
For researchers working on discrete-event systems and tropical algebra, this provides a novel abstraction technique that reduces computational complexity.
This paper develops finite abstractions of Max-Plus-Linear systems using tropical algebra, enabling efficient generation of abstract states and transitions. The proposed method shows improved computational performance compared to existing approaches on numerical benchmarks.
This paper describes the development of finite abstractions of Max-Plus-Linear (MPL) systems using tropical operations. The idea of tropical abstraction is inspired by the fact that an MPL system is a discrete-event model updating its state with operations in the tropical algebra. The abstract model is a finite-state transition system: we show that the abstract states can be generated by operations on the tropical algebra, and that the generation of transitions can be established by tropical multiplications of matrices. The complexity of the algorithms based on tropical algebra is discussed and their performance is tested on a numerical benchmark against an existing alternative abstraction approach.
