We present a new method for the accurate analysis of the quality-of-service (QoS) properties
of component-based systems. Our method takes as input a QoS property of interest and a …

Software systems, especially service-based software systems, need to guarantee runtime
performance. If their performance is degraded, some reconfiguration countermeasures …

We introduce a tool-supported method for the automated refinement of continuous-time
Markov chains (CTMCs) used to assess quality properties of component-based software …

结合民用飞机运行可靠性研究的技术现状与发展趋势, 根据现有的型号设计,
研制和在役飞机的具体情况, 阐述了民用飞机运行可靠性研究需求. 通过梳理民用飞机运行可靠 …

Various algorithms and tools for the formal verification of systems with respect to their
quantitative behavior have been developed in the past decades. Many of these techniques …

Labeled continuous-time Markov chains (CTMCs) describe processes subject to random
timing and partial observability. In applications such as runtime monitoring, we must …

Abstract The Communist Party of China proposed the concept of “speeding up the industrial
transformation and changing economic development mode” in its 17 th Congress. Against …

In an expected reachability-time game (ERTG) two players, Min and Max, move a token
along the transitions of a probabilistic timed automaton, so as to minimise and maximise …

Probabilistic timed automata are a suitable formalism to model systems with real-time,
nondeterministic and probabilistic behaviour. We study two-player zero-sum games on such …

Continuous-time Markov chains with alarms (ACTMCs) allow for alarm events that can be
non-exponentially distributed. Within parametric ACTMCs, the parameters of alarm-event …
