This paper presents new approaches for construction of knowledge-oriented control systems. The AND/OR-graph model is improved for control rules visualization and interactive processing. The knowledge-oriented system for the dispatcher that regulates the safe operation with electrical equipment made it possible to increase the reliability of decisions taken by the dispatcher by 12%.
Smart cities and smart homes are booming fields of development of pervasive systems. With the high stakes these systems have to manage, and their sheer complexity, anomalies have to be considered. In these complex systems are many connected components with computing capacities. They can manage anomalies, even if partially, and can act as some kind of expert systems. These expert systems can be relied...
Gene expression datasets contain a lot of gene expressions. It is very important to identify only relevant genes on huge datasets. Thus, feature selection is very important process. In this study, it is suggested a method which obtains both fast and high classification accuracy. For this reason, it is suggested a method which uses together statistical methods and wrapper methods. The experiments are...
The article is concerned with problems associated with expert system implementation for technical state and reliability assessment of power networks complex object, such as substation. The article presents operation algorithm and structure of designed expert system. The article also contains calculation example of technical state assessment of power transformer by means of neural fuzzy inference based...
This paper outlines the architecture of the ARISTON expert system shell for vocational counselling. The information system prompts the user to answer a series of psychometric questions, for a period of approximately 40 minutes. The system then analyses the answers and creates a report automatically and sends this to the e-mail address of the user, with no human intervention. The report contains analytical...
Human behavior understanding is the basis for the robot to provide intelligent service. According to the shortcoming of human behavior understanding with image processing, an expert system is built with the combination of CLIPS and VC++. Firstly, the context information provided by sensors in the intelligent space oriented to home service robot are collected and processed with VC. Since the information...
The incessant increment of the population and lack of the reliable bus position notification system in big cities is causing the boost of the privately owned cars, has created major traffic problems. First ever time, Response Surface Methodology (RSM) is adopted in this study to present a new real time intelligent buses notification system using routes' coordinates optimization and wireless mesh network...
Power transformers are the most important and expensive equipment in the electrical transmission systems. The transformers average age in the power system in Hungary is approximately 25 years. It is not economical to replace these equipment only because of their age. We have to know and manage more information about the insulation, because the status of the insulation is determines the expected lifetime.
Reliability parameters, such as the failure rates of power system components, are vital in evaluating power system reliability. This paper summarizes the research of the authors in using fuzzy inference systems to infer the failure rates of transmission lines in the power systems affected by hurricanes. The emphasis is on using fuzzy clustering methods to build fuzzy inference systems automatically...
Web services are the key technologies for the web applications developed using Service Oriented Architecture (SOA). Many outsourced web services can be combined to provide value added services to the users. There are many challenges involved in its implementations. One of the essential challenges is service discovery which involves finding a set of suitable web service candidates faster. When a large...
With the development of large-scale, intelligent and complex systems, the conventional fault tree analysis method is incapable of analyzing the fault tree model of systems with vague data and multi-state. As a solution, this paper proposes a new approach of fuzzy multi-state fault tree analysis method based on a fuzzy expert system. Fuzzy theory is applied to representing the degree of fault tree...
Every design engineer has an experience of facing common problems of short lead times, clear specification, sufficient design criteria, material costing, environmental regulations, and product reliability constraints. However, for maintaining sustainable growth of a company, a new product should be time-in-market that keeping business growth strategy. Under such environment, it is clear that more...
This paper shows the advantage of using Intelligent Systems while developing engineering projects. The paper is based on three examples and it is focus into one of them: The E-learning Migration application, developed as a teaching aid tool in different organizations where various platforms coexist; this is the case of some Spanish universities. This tool solves three basic problems, which are shown...
A system of Multiple Neural Networks has been proposed to solve the face recognition problem. Our idea is that a set of expert networks specialized to recognize specific parts of face are better than a single network. This is because a single network could no longer be able to correctly recognize the subject when some characteristics partially change. For this purpose we assume that each network has...
The model of EPC has been used in our construction industry for 20 years. In the bidding of the practical EPC, the prequalification is usually realized by the traditional procedure and method, which need complicated calculation and implementation process. On the basic process of EPC prequalification tender, this article develops the system of prequalification tender by means of Excel VBA, determines...
The accuracy and fairness of the assessment results to a large extent limited by the choice of methods of assessment data processing. In the current practice of the equipment support core competencies (ESCC) assessment, there are two methods of assessment data processing mainly used, which are named the simple arithmetic average method and the weighted arithmetic average method. In this paper, an...
The paper presents a platform, which offers to the possibilities to connect remotely via Internet to an industrial process in order to monitor, diagnose and control it remotely. In this way, several expensive resources like experts and powerful computers that simulate the complex processes from the customer site can be shared at distance through Internet in order to optimize the costs and to increase...
We propose a method of probability logic reasoning with threshold-surety to the problem of making inference from a knowledge base in experts system, which treats a finite set of premises in the knowledge base as assertions that are true with probability at least some primary threshold, and consider as a finite set of alternative conclusions those assertions probabilistically entailed to have probability...
Failure Mode Effects and Criticality Analysis (FMECA) is one of most widely used methods in modern engineering system to investigate potential failure modes and its severity upon the system. Although there are several FMECA standards, the most popular one is MIL-STD-1629A from U.S. department of defense. While carrying out FMECA, experts evaluate criticality and severity of each failure mode and visualize...
Based on the background of analysing "expert power" in data fusion technology, we put forward the problem of "expert power" fusion to be solved in real estate appraisal. By determining the fusion criteria and building the information model of reliability, we establish the appraised algorithm of information fusion. This method can improve the accuracy of evaluation, reduce the error...
