example of expert system in business

The problems the developers encounter are sometimes so great that they have to redesign the system from scratch. One can expect consistency from an ES, but ESs mimic the frailties as well as the strengths of human judgment. The entire process starts by extracting knowledge from a human expert, converting the acquired knowledge into rules and injecting the developed rules into the knowledge base. Meaning of Expert System 2. It provides reasoning about the information in the knowledge base. It is a person or group of people who are using the expert system to get to get advice which will not be provided by the expert. (An ES shell is a software tool that provides an integrated set of building blocks that can be used to create an ES program.). Expert System is an interactive and reliable computer-based decision-making system which uses both facts and heuristics to solve complex decision-making problems. But MUDMAN gave Baroid something unique to offer customers. They are “expert systems”—programs that mimic the thinking of the human experts who would otherwise have to perform the analysis, design, or monitoring (see the ruled insert for a detailed definition). The Expert System in AI can resolve many issues which generally would require a human expert. The rep simply specifies the machine types and the location-specific factors and the system generates a bid. Coopers & Lybrand has an ES called ExperTAX that helps accountants in reviewing the way their clients accrue taxes and in offering tax planning advice. …we had more time? Unable to make a creative response in an extraordinary situation, Errors in the knowledge base can lead to wrong decision, The maintenance cost of an expert system is too expensive, Each problem is different therefore the solution from a human expert can also be different and more creative, Useful for repair and maintenance projects, The configuration of manufactured objects, Financial decision making Knowledge publishing, Supervise the operation of the plant and controller, An Expert System is an interactive and reliable computer-based decision-making system which uses both facts and heuristics to solve complex decision-making problem, Key components of an Expert System are 1) User Interface, 2) Inference Engine, 3) Knowledge Base, Key participants in Artificial Intelligence Expert Systems Development are 1) Domain Expert 2) Knowledge Engineer 3) End User, Improved decision quality, reduce cost, consistency, reliability, speed are key benefits of an Expert System. Suddenly the company could differentiate itself from competitors. MUDMAN and XCON are not ordinary computer programs though. When technical experts alone determine the performance and application characteristics, the applications often fail to meet a real business need. Of course, this long incubation period can constitute a competitive advantage. These prices were the starting point for negotiations among the customer, the field service representative, and service management. Many ESs are written in computer languages like LISP and Prolog, which are good at manipulating symbols as well as numbers. A help desk is a type of expert system which allows customers to obtain service or help when detect problems relating to a certain object, for example, a person is having problems connecting to the internet, there will be a message that appears on the screen that may give a specific error number, and the system will allow the customer to go through a series of questions and tries to solve the problem. Major oil companies shop for price and ration purchases among many eager suppliers. Sometimes projects begun with one objective in mind have led to the other. One such benefit is the way an ES can help people in the organization understand a problem better. When a turbine fails, it sometimes throws pieces of steel, whirling at thousands of revolutions per minute, into protective castings, causing tens of thousands of dollars worth of damage and weeks of downtime. An expert system shell is a programming environment that contains the necessary utilities for both developing and running an expert system. Some of them are given below: MYCIN: One of the earliest expert systems based on backward chaining. Companies don’t always have enough of the expertise they need. However, discerning the subtle irregularities that were visible to an expert’s eye proved beyond the operators’ capabilities, and the developers could not write software to perform that expert task. Often more interesting—and ultimately more valuable—than the hoped-for gains in productivity and effectiveness are the many unexpected benefits that flow from ESs. Following are examples of Expert Systems 1. Cuts the expense of consulting experts for problem-solving. The relationships shown here are … Problem solving is only a small part of what an expert does in a company. Outside experts are expected to have a deep understanding of ES tools and methodology so they can develop a working system quickly, and they bring a fresh perspective. Finally, building an ES is a foot in the door to artificial intelligence. In the early days at Stanford, the knowledge base consisted of medical “rules” in the form of IF-THEN statements with an associated confidence factor. The ES provides a complete and consistent set of questions covering all aspects of any proposal. It was originally intended to be used by salespeople to check the configuration at the time they created a new order for a computer system. Knowledge database and the processing mechanism are two separate components. It refers the knowledge from the Knowledge Base. Only when XCON was revised to make two checks—one for review and approval by sales and one for manufacturing—did it perform adequately. The money DuPont might otherwise have spent on consultants it spends on training people in the use of the shells. It could also recommend drugs based on the patient's weight. Texas Instruments uses its Capital Investment Expert System to help employees who are making capital budgeting requests. It stores all the knowledge about the problem domain. Once expertise is outside someone’s head, more people can work at refining it, and as it is fine-tuned, problem solving moves from art to science. An Expert System can be used for broad applications like Stock Market, Warehouse, HR, etc. Organizations that build one system learn in the process how to do it faster and better the next time. Expert systems … Knowledge base– a set of rules as representation of the expertise, mostly in IF THEN statements. Probably the most famous business application is XCON (for eXpert CONfigurer). But to take that position is usually to misunderstand (and underestimate) the process by which expertise is captured. Making the distinction is necessary because you must know what experts should be involved in building a system and you must have a clear idea of what standard to use when measuring its performance. As these examples show, expert systems can support various competitive strategies by differentiating a product or by lowering costs. Limitations of Expert System. Steam power removed horsepower and manpower. The best ESs to date capture only a portion of the expert’s knowledge. It is like a large container of knowledge which is obtained from different experts of a specific field. If a human expert is hired away or is too busy to teach younger colleagues, an ES can help by serving as a training tool. A third test of feasibility is whether you can identify the abilities that differentiate an expert from a novice. The projects that succeed are usually driven by a domain expert or business manager. AMEX’s Authorizer’s Assistant can use the rules and data much faster than a human expert. All rights reserved. As exciting and promising as ESs are, overenthusiasm can sometimes lead to unfounded assumptions and unrealistic expectations.2 A typical claim is that expert systems help companies “clone experts.” That claim is overblown. In some instances, new businesses have sprung up. The system also helps individual managers analyze their situations more completely. Some managers use the total number of users or amount of usage as measures of success. Some companies contract with university researchers to create prototypes that are developed in-house; MUDMAN and XCON both began with prototypes developed at Carnegie-Mellon University. And the organizational impact—the creation of new job categories, the necessity for training programs, or the alteration of career paths—also varies. Working storage– the data which is specific to a problem being solved. The technical editors at Digital couldn’t use the first version of XCON. MYCIN: Historically, the MYCIN system played a major role in stimulating research interest in rule-based expert systems. An expert system is an example of a knowledge-based system. The result was XCON, an expert system that checks sales orders and designs the layout of each computer order it analyzes. The project overseer must be able to tolerate the high degree of ambiguity inherent in developing ESs. The new system, along with the creation of a data base and an improvement in component quality, allows Digital to ship most components directly to the customer site for final assembly, thereby eliminating the need for additional final assembly facilities. The idea is that, as people become comfortable with the technology, they will discover useful applications on their own. Example # 1. Just as a poem can be translated from one language to another, it is possible to achieve comparable functions with Fortran, COBOL, or any other computer language, but symbolic programming languages are often more efficient at solving tasks requiring large amounts of human knowledge to be encoded. When a drilling rig is having trouble with a well, the people involved must stay on the job sometimes for days at a time. But ESs also generate evaluations and recommendations based on the data and models. But once the information has been drawn from the expert and the software created, the rules, examples, and data provide a mental mirror with which the expert can explore, explain, and elucidate the nature of his or her expertise. The system is operational only when fully developed. In some cases, they have helped organizations understand vital processes and procedures. The development team for large-scale projects should have three types of talent: domain, technical, and managerial. Expert systems (ESs) have been used successfully for design, diagnosis, and monitoring in a range of industries—from computers to accounting. Managers may find that uncertainty frustrating. After that, it displays the results to the user. XCON allows the company to apply expert knowledge to a task that is routine but important. The organizational prototyping mentioned earlier can help to highlight the best measures of success. Their experience shows that expert systems are indeed a valuable tool for capturing and disseminating skill and knowledge, often to create competitive advantage. Step by step execution according to fixed algorithms is required. Expert systems are a subset of AI projects that attempt to achieve expert-level results in solving tough problems like contract estimation or air freight scheduling. There is no precise demarcation between an ES and a traditional software system. For pragmatic reasons, most companies turn to experts outside the company who are practiced at eliciting and encoding an expert’s rules of thumb. This has occurred in many cases in which the roles of individuals who used the ES have changed greatly. Once they passed this test, the computers were disassembled and shipped to the customers. AMEX employees understood well the process of credit authorization. The experts must evaluate each version of the system and compare the reasoning that is being embedded in the system with their own thinking. Most ESs currently in wide use in companies originated in a functional area, not the MIS department. Meaning of Business Expert System: A business expert system has been designed to provide expert advice to the business executive. DuPont, for instance, gives employees small, PC-based ES shells and encourages them to build systems tailored to their specific needs. There are numerous examples of expert systems. Once you’ve identified the ES opportunities, you must assess the feasibility of applying the new technology to those tasks. For example, some ESs are used like a training tool: novices use the ES extensively for a few months until they’ve learned all it has to offer, after which usage drops off until a new batch of beginners appears on the scene. Moreover, the learning garnered in the process of questioning experts and structuring their knowledge provides valuable insight that often leads to efficiencies in task execution. The ability to process symbols is important because knowledge is usually built into ESs by “if…then” rules. 2. It is considered at the highest level of human intelligence and expertise. As we have seen, expert systems have already allowed novices to perform expertlike tasks. It provides in-house training and uses consultants. Among the earliest users in Europe, three different patterns of usage emerged. One that can be solved in a few minutes to a few hours is a reasonable candidate. …we had consistent decisions? In 1973, faced with the prospect of adding tens of millions of dollars worth of assembly and test facilities to accommodate sales growth, Digital sought an alternative. The term knowledge acquisition means how to get required domain knowledge by the expert system. IBM field service employees needed a better shared understanding of how to price complex jobs or how far to alter the standard price. Through use of PlanPower, for example, a clerk began to acquire the expertise of a financial planner. They also cite XCON as an important contributor to Digital’s long-time strategy of offering customers many options. It has the ability to identify various bacteria that cause severe infections. Drawing talent from any of these sources has its advantages and drawbacks. And think about whether the problem can be described in words. Meaning of Business Expert System 2. Targeting a particular task doesn’t always tell you who the system users will be, because actual usage often diverges from the plan. He is a person or group whose expertise and knowledge is taken to develop an expert system. Classes of Expert System 3. Limitations of Computerized Business Expert System 3. The knowledge base is a repository of facts. Authorization requests outside the normal buying pattern require a search of the data bases for more information. The understanding revealed is therefore of value both to the expert and to the members of the organization dependent on the expertise. The insight gained can translate into productivity gains, tailoring of job roles, and a better sense of users’ needs for future systems. The first step is to identify the opportunities. The domain expertise, or knowledge of how to perform the task, is usually provided by the expert who has been doing the job. Expert systems, or decision support systems, are artificial intelligence systems that have been trained with real cases to perform complicated tasks. While it was technically accurate, it did not fit the way business was customarily conducted. That feature is important for competitive reasons, but determining the credit level for each customer poses a stiff administrative challenge. They are used in a variety of areas and are among the most popular application fields in artificial intelligence. They had assumed operators could detect defects which could then be diagnosed by the software. The exploratory nature of the development process makes it hard to predict how useful the project will be. But observation of dozens of systems in development and use indicates that the more mundane tasks are among the most fruitful areas for new applications. CaDet: Expert system that could identify cancer at early stages The need for domain and technical talent is so obvious that these two are never overlooked. The major components of expert system are: 1. MYCIN: It was based on backward chaining and could identify various bacteria that could cause acute infections. AMEX expects its Authorizer’s Assistant not only to raise an authorizer’s productivity by as much as 20% but also to reduce losses from overextension of credit (the exact financial benefit is kept secret). Digital’s XSEL (eXpert SELling assistant) was designed to interact with XCON. Organizations are replete with tasks for which doing things faster means doing them better. People who are afraid to ask questions because they are expected to know the answers can consult with an ES in private. A Business Expert System (BES) is a knowledge based information system, which is based on artificial intelligence. Some popular Application of Expert System: What is Data Mining? Such systems are expected to be small, have a short development time (months, at most), and provide a quick payback. Computers removed clerical staff in industries like insurance. Determining the characteristics of the problem, Knowledge engineer and domain expert work in coherence to define the problem. If the expert needs to see or touch the data, the task may not be well suited to an ES. The system might help experts work faster, apprentices work more consistently, or novices get started at the job. It evaluates the data the engineer enters and, by combining these with historical data for that particular well, identifies trends. They have much less experience managing expertise when machines help record and animate human efforts to capture and transfer knowledge. Thus we can say that the success of the Expert System Software mainly depends on the highly accurate and precise knowledge. It can be functional with sufficient or insufficient information. The following diagram displaying expert system components and human interfaces. Think of an economics academic who is working away in obscurity for decades before finally winning a Nobel Prize. 3. Besides, assessing whether an answer is “correct” is often a matter of opinion. An ES used by novices differs from one used by the experts themselves. An early version of a system can appear to be more impressive than its true capabilities warrant, leading people to underestimate the amount of work left to be done before the system is ready for use. The engineer analyzes readings on some 20 parameters including viscosity, specific gravity, and silt content. The next wave of ESs may be even more powerful and valuable. Knowledge engineer is a technical person who integrates knowledge into computer systems. Clipping is a handy way to collect important slides you want to go back to later. Examples include agriculture, education, environment, law, manufacturing, medicine, power systems, tax assessments and loan applications. Prospector 3. Expert systems generally consist of three main parts: 1) the explanation generator and user interface, 2) the inference engine, and 3) the knowledge base. Companies including IBM and Texas Instruments have a combination of large-scale and small-scale projects. The oil company customer was so impressed that it bent its policy and invited Baroid to bid on “more than the normal” share of business. General Motors purchased an equity stake in Teknowledge, Inc., an ES consulting firm it had been using. Some managers find this horribly wasteful. Today's increase in computing power and Internet technology have given expert systems a new lease of life, and many applications can be accessed by personal computer or even smartphones. And hiring a full-time staff that knows ESs is for most companies prohibitively expensive. The AMEX employee then has to make a quick judgment call. These projects require a team of people with the right mix of talent and take from six months to at least two years to create and implement. For years IBM had a set of standard prices for provision of after-sales services to install, relocate, or remove computers. Inference engine contains rules to solve a specific problem. Muds are a commodity business whose buyers are few and powerful. During the early 1970s, human experts—known as technical editors—ensured that each computer system on order had all the necessary components and no extras and made diagrams showing how to assemble the system.
