摘要： 1.Can agiven diagnostic model be implemented on the basis of the available sensors? This problem is commonly referred to as diagnosability,and had been studied in a variety of works.2.We see diagnosability as a disambiguation problem for sets of states that don't necessarily partition the states 阅读全文

摘要： 1.An automaton that is both accessible and coaccessible is said to be trim.2.We define two operations on automata:product,denoted by ×,and parallel componsition,denoted by ||.3.The || operation involves all events in E1∪E2 while the × operation involves only events in E1∩E2. 阅读全文

摘要： 1.There is a set of unmarked states in G that forms a strongly connected component,but with no transition going out of the set ,If the system enters this set of states, then we get what is called a livelock.2.An automaton G could reach a state x where Γ(x)=∅ but x/∈Xm ,this is called a deadlock beca 阅读全文

摘要： 1.A Deterministic Automaton,defined by G,isa six-tuple G=(X,E,f,Γ,x0,Xm)where: X is the set of states E the finite set of events associated with G f:X×E→X is the transition function:f(x,e)=y means that there is a transition labeled by event e from state x to state y;in general,f is a partial fu 阅读全文

摘要： 1.Using the automaton formalism,we will present solution techniques for three kinds of verification problems.those of safety(avoidance of illegal behavior),liveness(avoidance of deadlock and livelock),and diagnosis(ability to detect occurrences of unobservable events).2.One of the formal ways to stu 阅读全文

摘要： 1.Systems that combine time-driven with event-driven dynamics are referred to as Hybrid Systems.2.Summary of system classifications: Static and Dynamic Systems.In static systems the output is always independent of past values of the input.In dynamic systems,the output does depend on past values of . 阅读全文

摘要： 1.A queueing systemcomprises by three elements:entities,resources,and space.2.In order to fully specify the characteristics of a queueing system ,we need to define the capacityof the queue,and the queueing disicipline.3.DBMS :database management system.next :software system :telephony P64 阅读全文
