Aircrafts, trains, cars, plants, distributed telecommunication military or health care systems, and more, involve systems design as a critical step. Complexity has caused system design times and… (More)
This paper addresses the problem of distributed program synthesis. In the rst part, we formalize the distribution process and prove its correctness, i.e. that the initial centralized program's… (More)
The foremost motivation for introducing communication into the decentralized discrete-event control problem is to allow controllers to distinguish between behaviors of a system that remain within a… (More)
The numerical simulation of non-smooth hybrid systems exhibiting chattering behavior requires high computational costs. In the worst case, the simulation appears to come to a halt, since infinitely… (More)
Hybrid systems exhibit mode-dependent continuous-time dynamics. They are encountered in several phases of Cyber-Physical Systems design: physical system modeling, budgeting time over the computing… (More)
Modular design aims at building complex reactive systems by assembling components, possibly taken off-the-shelf. This approach can be supported by a specification theory in which requirements… (More)
In this paper we revisit the fundamentals of interface theories. Methodological considerations call for supporting “aspects” and “assume/guarantee” reasoning. From these considerations, we show that,… (More)
In this paper, we present an Assume/Guarantee contract formalism for systems combining nondeterministic and stochastic aspects. Contracts dictate how component variables behave, being either… (More)
