For a deadlock problem in automated manufacturing systems (AMSs) with unreliable resources, the existing control methods mostly belong to the class of deadlock avoidance. This paper focuses on deadlock prevention for AMSs with an unreliable resource. We use Petri nets to model such AMSs and develop their robust deadlock prevention controller. The controller is designed in three layers. In the first...
Interaction property is a natural feature of many distributed systems which finish their work on network. But most of them face state explosion when the test work is analyzed and developed with a formal model such as Petri net. In order to avoid such problems, test based on interaction property is considered. It can focus on the interesting features of a system and ignore the other irrelevant part...
The aim of property based testing is to validate an IUT with respect to a target property, to observe whether the property is violated or not. Many distributed systems have a natural feature-Interactive property. But most distributed systems face state explosion when the test work is analyzed and developed with a formal model. In order to avoid such problems, this paper presents a testing method that...
