Event Processing in an Object-Oriented Rule-Based System
نویسنده
چکیده
This paper describes concepts being developed for processing events in a rule-based system, to be deployed in an embedded system that is part of a railway interlocking system, used as a safety-motivated secondary software channel. Events are either status notifications or operator commands, both of which operate on elements in a railway interlocking plant. It is shown that an object-oriented hierarchy of fact types results in a compact set of rules for processing both event types, illustrated by a prototype implementation.

Modeling and simulation of processing plants are widely used in industry. Construction of a mathematical model for a plant is a time-consuming and error-prone task. In light of extensive advancements in computer science (both hardware and software), computers are becoming a necessary instrument in industrial activities. Many software tools for modeling, simulation and optimization of proces...
متن کاملDeclarative Semantics in Object-Oriented Software Development - A Taxonomy and Survey
One of the modern paradigms to develop an application is object oriented analysis and design. In this paradigm, there are several objects and each object plays some specific roles in applications. In an application, we must distinguish between procedural semantics and declarative semantics for their implementation in a specific programming language. For the procedural semantics, we can write a ...

As the information carried in a high spatial resolution image is not represented by single pixels but by meaningful image objects, which include the association of multiple pixels and their mutual relations, the object based method has become one of the most commonly used strategies for the processing of high resolution imagery. This processing comprises two fundamental and critical steps towar...
متن کاملOn Attributes of Objects in Object-Oriented Software Analysis
One of the modern paradigms to develop a system is object oriented analysis and design. In this paradigm, there are several objects and each object plays some specific roles. There is a sequence of activities to develop an analysis model. In the first step, we work in developing an initial use case model. Then in the second step, they identify a number of concepts and build a glossary of partic...
متن کاملObjects Identification in Object-Oriented Software Development - A Taxonomy and Survey on Techniques
Analysis and design of object oriented is onemodern paradigms for developing a system. In this paradigm, there are several objects and each object plays some specific roles. Identifying objects (and classes) is one of the most important steps in the object-oriented paradigm. This paper makes a literature review over techniques to identify objects and then presents six taxonomies for them. The f...
