Culture is a term for the set of traditional and habitual ways of thinking, feeling, reacting to opportunities and problems that confront an organization. Both structure and culture might influence the way information flows through the organization. Computers have been used in the clothing industry since the earliest introduction of IT.

In those days only the very large tailoring companies had the resource to take up this technology. They used them mainly for business data processing. During this decade, the textile industry has progressively taken up computerization. The application of computers is wide ranging covering almost all activities necessary to run a textile business: accounting and transaction processing, sales and marketing, production planning, computer-aided management, real-time management etc.

Over time the nature of computer systems in their implementation has taken several forms: standalone applications based on one computer; an integrated centralized system where one large computer handles a range of applications; applications catered for by having ones data processing distributed over a network of computers. A lot of clothing companies continued to invest not only in very latest production technology, but also in design technology and computer systems.

MIS in clothing companies should include the control of the stock, processing of each individual order, accounting etc. Most of the tailoring enterprises have a web site and in this way e-commerce is widening. Electronic commerce is global and requires increased international coordination. Its implementation opens not only new markets, but it also changes the way in which business is made.

E-commerce over the World Wide Web is growing at an astronomical pace. Many of the top e-commerce sites report revenue growth exceeding percent per year. Europe is late in developing and implementing of the modern IT. So, by using the ES productivity and relationship with the customer increases which is the main principle of business.

Amount of fat depends on breed, food, placement of the animals, weather, and many other factors. Animal scientists know what they want, but they cannot find the correlation between these factors. So, developing the neural network, or fuzzy logic or expert system to guide decision during the raising of the animals will help to achieve the quality and cut down cost.

This will be done by using Expert system, neural network that will firstly do identification and modeling and then will consider other various factors together with mammogram results to give accurate result and helps us in making decision. And system that must be able to understand from environment and to make such an expert system those are able to maintain itself and able to update itself. Today’s expert systems deal with domains of narrow specialization. For expert systems to perform competently over a broad range of tasks, they will have to be given very much more knowledge.

The next generation of expert systems will require large knowledge bases. And research is being going on it. ES can be cheaper, faster, more accessible, and more reliable than humans Intelligence. A large number of expert systems are in real use and quite a few even being sold for individual use. In the future one is likely to see more expert systems packaged with domain knowledge being sold.

Further, these systems are also likely to carry out specialized tasks as parts of much larger software systems. With ES productivity and relationship with the customer increases which is a main principle of business. ES agents teach the student in same way as a teacher teaches to them. References [1] Dutta.

The most common form of semantic networks uses the links between nodes to represent IS-A and HAS relationships between objects.

Example of Semantic Network The Fig. This kind of relationship establishes an inheritance hierarchy in the network, with the objects lower down in the network inheriting properties from the objects higher up. A frame-based representation is ideally suited for objected-oriented programming techniques. An example of Frame-based representation of knowledge is shown in next slide. Working Memory.

Consequently, ab kr ha it is the most dynamic component of an expert system, assuming that it is C C R kept current.

Inference Engine. The Forward chaining, Backward chaining and Tree searches are some of the techniques used for drawing inferences from the knowledge base.

However they are relooked in the context of expert system. Forward-chaining inference is often called data driven. Backward-chaining inference is often called goal driven. C C R Note : Here these two search are briefly mentioned since they were described with examples in the previous lectures. Expert System Shells. It ty or contains the basic components of expert systems. A shell is associated ab kr ha with a prescribed method for building applications by configuring and C C R instantiating these components.

The knowledge base and reasoning engine are the core components. Expert system tool or ab provides one or more knowledge representation schemes for kr ha C expressing knowledge about the application domain. However, collecting knowledge, needed to solve problems and build the knowledge base, is the biggest bottleneck in building expert systems. The explanation can range from how the final or intermediate solutions were arrived at justifying the need for additional data.

The user interface is generally not a part of the expert system technology. It was not given much attention in the past. However, the user interface can make a critical difference in the perceived utility of an Expert system. The rules typically reflect empirical, or “compiled” knowledge.

They are codes of an expert’s rules of thumb, not the expert’s deeper understanding. Example : Dialog with an expert system designed to give advice on car problems. System Does the car start? User No. System Does the engine turn over? User Yes. System Do you smell gas? User Yes System Recommendation – Wait 5 minutes and try again. User Why? Types of Explanation There are four types of explanations commonly used in expert systems.

Application of Expert Systems. The applications of expert systems technology have widely proliferated ab kr ha to industrial and commercial problems, and even helping NASA to plan C C R the maintenance of a space shuttle for its next flight. The main applications are stated in next few slides.

However, the diagnosis of engineering systems quickly surpassed medical diagnosis. The Expert systems have been very useful to find solutions. For example, modular home building and manufacturing involving complex engineering design.

Insurance companies to assess the risk presented by R the customer and to determine a price for the insurance. Here the primary function of the Expert system is to deliver knowledge that is relevant to the user’s problem. The two most widely known Expert systems are : one, an advisor on appropriate grammatical usage in a text; and the other, is a tax advisor on tax strategy, tactics, and individual tax policy.

This rule-based programming technique has been applied in such diverse fields as medical diagnostic systems, insurance and banking systems, as well as automated design and configuration systems. Rule-based programming is also helpful in bridging the semantic gap between an application and a program, allowing domain specialists to understand programs and participate more closely in their development.

Over sixty programs are presented and all programs are available from an ftp site. Rule-Based Programming will be of interest to programmers, systems analysts and other developers of expert systems as well as to researchers and practitioners in artificial intelligence, computer science professionals and educators. The development of an expert system is viewed as containing three separate, but highly interacting components: knowledge capture, programming and debugging the system, and finally placing the system before an active user community.

Some of the issues in each of the three components, the application of general human factors principles in the design of expert systems, the special needs in the design of expert systems, and the efficacy of these interfaces. AI expert and consultant William Taylor provides a practical explanation of the parts of AI research that are ready for use by anyone with an engineering degree and that can help engineers do their jobs better. Taylor tours the field of artificial intelligence in a highly readable and engaging manner, outlining in detail how engineers can work with AI.

In separate chapters he discusses the three basic programming styles – function-based programming, object-oriented programming, and rulebased programming – as well as the use of Lisp and Prolog.

He concludes by offering several suggestions for getting started in the field. As Taylor defines it, AI is a programming style that has much in common with engineering practice: programs operate on data according to rules in order to accomplish goals.

While the term “artificial intelligence” is generally defined as meaning the design of computers to think the way people do, Taylor points out that for engineering purposes it is more accurately defined as a few software ideas that work well enough to be used.

And as AI technology matures, computers will be able to provide actual design help. They will, in effect, serve as design apprentices, offering suggestions and handling actual parts of the design. William A. Taylor is an international consultant on the practical applications of artificial intelligence and has spent several years giving seminars on AI to senior engineers and engineering management. All Rights Reserved. They form a wide survey of methods Regarding the differences between writing a program in a designed for both reasoning under uncertainty and inexact procedural language and implementing an expert system, it is reasoning.

In contrast with logical approach described in the very important for students to complete one or two small previous chapters, these methods are important for expert expert systems of their choice. Their task should not be only system application involving uncertain information. The the implementation of the given techniques but the project uncertainty may apply to facts data , knowledge rules or should consist primarily of choosing the most appropriate both.

A number of techniques has been suggested to deal method for the problem in question. For this purpose, a with uncertainty in expert system but some of them are wide range of methods and techniques used for knowledge heuristic, not supported by a mathematical theory.

It is a representation and processing in expert systems constitutes virtue of the book that it emphasizes theoretically sound the content of the first part of the book, approaches based on either classical probability theory, As already mentioned above, there is no exact definition of Dempster-Shafer theory or Zadeh’s fuzzy theory. All the expert system. To be called an expert system, a program three approaches are introduced in the book with help of product has to meet several requirements.

There is a examples some of which are used several times to show the common consensus about some of them; others are claimed differences between the individual models. And yet, it is very difficult, almost I have hitherto commented mainly positive aspects of the impossible, to say that some requirements are more book.

Now, I would like to mention a certain imperfection important than others. All this wavering is reflected quite affecting presentation of some theoretical parts and issuing naturally in the first part of the introductory Chapter 1. Though there is only one paragraph entitled “What is an For example, when the classical probability theory is expert system”, it takes, in fact, nine of them to answer the presented, basic terms like sample space, random variable, question.

The remainder of Chapter 1 is devoted to probability distribution, conditional probability or explanation of the most popular techniques and paradigms independent events are explained and illustrated with employed in expert systems today. In addition, as an examples. Nevertheless, the authors do not introduce example of a prospective technique, artificial neural systems concepts like multidimensional distribution which would are introduced. Whenever a new term is of the probabilistic expert systems.

Similarly, when mentioned, it is illustrated with examples and relations to discussing resolution as the principal inference rule in other similar concepts are explained. When, for example, PROLOG it might be useful to mention its ways of production systems are introduced, the authors do not restrict implementation and connected problems though it can be themselves only to stating that knowledge is represented in a found quite easily almost in any PROLOG manual.

To offset the subjectivity of Giarratano and G. Statistical Software Newsletter 19, 2, There is no doubt that from this point of view the book is a success.

This About the reviewer feeling is increased also by the fact that each chapter is Radim Jirougek was born in Prague, Czechoslovakia. He supplemented with exercises and problems. Nevertheless, the graduated in mathematics from Charles University, Prague, book taken as the only source of information may leave a in , and received the CSc an equivalent of Ph.

Let us stress that this fact does not, however, Academy of Sciences in Zadeh’s foreword: where he researched mathematical methods of diagnosis. Department of Decision Systems Theory.

His present interest lies in uncertainty processing in expert systems with Reference emphasis on probabilistic methods. He has published over 40 Streitbcrg, B.

Amos Reviewer: E. The iterative procedure between AUTOMATIC control of large flexible space structures is one of control system design and modelling approximation is the key issues in future spacecraft design. The problem is therefore the first key issue in control-structure interaction. Examples for control systems of the first type disturbing environment. Robustness is required to assume are in-orbit manufacturing facilities with large solar panels stability and minimum in-orbit performance in the first place and of the second type are very large space telescopes and while fine tuning can be done later by in-orbit identification laser pointing systems requiring pointing and target tracking and adaptation of control configuration and parameters with to an accuracy of 0.

The problem to be the spacecraft already flying in its real environment. Even with the powerful engineering requirements in an optimal way. This has to be design tools available nowadays, the importance of doing the kept in mind in order to frame the right question and solve right tests on a component as well as on a control system the real problem.

Only by testing can it be For this new type of space systems, control engineers and proven that the control system design problems have been mechanical engineers have to come together early on a solved correctly and that the right problems have been system engineering level to properly match control systems solved. Concerning dynamics and control of large flexible and structural design parameters to meet overall require- space structures, we are, with all three key issues, just in the ments, and to predict on orbit performance of the space beginning.
