Abstract Fluid (or Hybrid) Petri Nets are Petri net based models with two classesof places: discrete places that carry a natural number of distinctobjects (tokens), and fluid places that …
Restarts or retries are a common phenomenon in computing systems, for instance, in preventive maintenance, software rejuvenation, or when a failure is suspected. Typically …

Performance of a software system can deteriorate from higher to lower levels due to software aging. To counteract the aging effect, software rejuvenation is widely implemented to restore …
As modern society relies on the fault-free operation of complex computing systems, system fault-tolerance has become an indispensable requirement. Therefore, we need mechanisms …

Availability prediction in a telecommunication system plays a crucial role in its management, either by alerting the operator to potential failures or by proactively initiating preventive …
We analyse and optimise the completion time for a class of jobs whose conditional completion time is not always decreasing with the time invested in the job. For such jobs …
The usage of models is a fundamental activity in designing and verifying a system. Mastering different modeling techniques and scaling their application to complex systems is …
