چکیده
This paper demonstrates the enhancement in ;maintainability made possible by introducing metal-level control architectures to production systems. We msess t h e amount of eflort expended in upgrading a rule base through the range referred to b y maintenance staff f o r d e base upgrading. The rule base of an Intelligent C A I System currently in operation that employs the raeta-level control architecture and an identical one without the architecture have been upgraded so that they satisfy the same upgraded specifications. Tihe measured range confirms that the meta-level control architecture curtails the effort expended in upgrading the rule base b y 19%. In particular, the effort expended in upgrading control flow is reduced b y 41%.

A rule-based evaluation of ladder logic diagram and timed petri nets for programmable logic controllers
This paper describes an evaluation through a case study by measuring a rule-based approach, which proposed for ladder logic diagrams and Petri nets. In the beginning, programmable logic controllers were widely designed by ladder logic diagrams. When complexity and functionality of manufacturing systems increases, developing their software is becoming more difficult. Thus, Petri nets as a high l...
متن کاملReliability and Performance Evaluation of Fault-aware Routing Methods for Network-on-Chip Architectures (RESEARCH NOTE)
Nowadays, faults and failures are increasing especially in complex systems such as Network-on-Chip (NoC) based Systems-on-a-Chip due to the increasing susceptibility and decreasing feature sizes. On the other hand, fault-tolerant routing algorithms have an evident effect on tolerating permanent faults and improving the reliability of a Network-on-Chip based system. This paper presents reliabili...
متن کاملMeta - level Inference Systems
In this book we will be concerned with a particular type of architecture for reasoning systems, known as meta-level architectures. The book is divided in two parts. The first part discusses general properties of metalevel systems, whereas the second part concentrates on a particular efficiency problem associated with meta-level systems. After presenting the arguments for meta-level systems (cha...
متن کاملUsing Rule-Based Concepts as Foundation for Higher-Level Agent Architectures
Declarative programming using rules has advantages in certain application domains and has been successfully applied in many real world software projects. Besides building rule-based applications, rule concepts also provide a proven basis for the development of higher-level architectures, which enrich the existing production rule metaphor with further abstractions. One especially interesting app...
متن کاملAnalysis of Applying Event-triggered Strategy on the Model Predictive Control
In this paper, the event-triggered strategy in the case of finite-horizon model predictive control (MPC) is studied and its advantages over the input to state stability (ISS) Lyapunov based triggering rule is discussed. In the MPC triggering rule, all the state trajectories in the receding horizon are considered to obtain the triggering rule. Clearly, the finite horizon MPC is sub-optimal with ...
