전통적 그리고 인터넷 기반 관광정보시스템은 각각 관광에 대한 포괄적이고 유용한 정보를 제공한다. 그러나 이들 시스템은 사용이 어렵고 사용자의 요구에 적절하게 대응하는 융통성을 갖지 못하고 정형화된 정보를 보여줄 뿐이다. 본 연구는 이러한 문제점을 해결하기 위하여 지식기반 전문가시스템 접근방식을 도입하고 있다. 이 방식을 이용하여 뉴질랜드 관광안내를 위한 한 전문가시스템이 사례로 제시되고 있다. EXSYS로 구현된 이 시스템은 사용자의 맞춤 여행계획을 제공한다.

본 논문의 목적은 지상작전 시 피아간 상대적 전투력을 분석하는데 전문가 시스템을 이용하는 방안을 제시하는 것이다. 상대적 전투력 분석은 지휘관 및 참모들이 부대를 어떻게 운용할 것인가에 대한 방향을 설정할 수 있기 때문에, 그 절차는 신속하고 이성적인 의사결정의 과정을 필요로 한다. 여러 애플리케이션들이 탑재될 수 있는 전술정보통신체계가 10년 동안 개발되고 있지만, 상대적 전투력 분석의 절차는 의사결정에 관여한 일부인원들에 의해 수작업으로 진행되어왔다. 본 연구에서는 이론적으로 3가지 상대적 전투력 분석방법을 고찰하고 이를 시스템에 지식(Knowledge)롤 사용될 수 있도록 수치적으로 표현하고, 유형뿐만 아니라 무형의 전투력도 지식에 포함될 수 있는 방안이 연구되었다. 기존의 대대급 전투력 지수와 수치적으로 표현된 지식을 이용하여 상대적 전투력 분석을 위한 전문가 시스템은 EXSYS Corvid로 구현되었다. 의사결정의 오류를 줄이고 빠른 의사결정을 가능하게 하며 유형뿐만 아니라 무형의 전투력까지 의사결정에 반영할 수 있을 것으로 기대된다. 향후에는 전투력 분석뿐만 아니라 인사분야나 정보 분석 분야에도 전문가 시스템을 도입하는 방안이 연구되어 객관적이고 합리적인 군 의사결정체계에 기여해야 한다.

Overhead cranes which carry heavy items in construction or production areas consist of structure and electric modules. More than 80% of breakdowns bring out of the electric module. As operators do not know all about cranes, it sometimes takes much time to repair the cranes. In order to resolve this problem, the expert system which can diagnose causes of faults and give instructions for repair to operators, has been developed. The scope of the paper is limited to the electric module. First of all, analyzing symptoms and causes, we have developed a rule base with the expert system shell, EXSYS. Furthermore, for the facility maintenance including repair instructions against the causes, the instruction data base was developed with FOXPRO. On the other hand, for the help of user's understanding the fault causes, the graphic animation module which shows malfunctioning component ports or motions in 3D was developed with the graphic software, TOPAS VGA.

A computer expert system for guiding Japanese style meal menu has been developed by using EXSYS Professional which is one of expert system developing software tools. The expert system nunderstands the situations of clients, and can guide the menu as human experts do by its software program with expert knowledge about the meal menu. In developing the expert system, the elements the clients consider when selecting menu were arranged as questions of the expert system, and the final outcome of the expert system resulted in selecting the final menu appropriate for the client demand, weather, health, etc. In hotel, the expert system can be shared by whole restaurants, and be directly a computer guider to the clients to tell the best choice of the menu. Besides, it can be used for various kinds of bangquets and events. Expert system has been developed and studied by business managers, manufactures, medical fields, and military field. But the studies for applying the expert system in the fields of foods have been scare. Through this study, therefore, the expert system is going to be applied more widely in many fields fo food events.

A prototype expert system for normal concrete mix design was developed using an technical consulting system development tool, EXSYS Professional. The knowledge contained in the system was obtained from the standard specifications of Korea Concrete Institute, American Concrete Institute and from the related British Standards. The knowledge base and user interface will be expanded to cover wider scopes of the problems. If the system is successfully developed as an operational system, it will produce a great deal of economic benefits by reducing the time and money needed to obtain an expert's judgement and experience in decision making for repetitive tasks related to concrete mix proportions.

The control chart has been used widely and importantly as a tool for statistical process control(SPC). Most companies are concerned with improving the quality and the productivity as well as reducing the cost, especially in today's highly competitive environment. Though SPC is known as a technique for consistent quality, it is not used properly due to lack of knowledge about it. It is required to develop a support system for control chart selection and interpretation that can be utilized by non-specialist without hard training or experiences. The support system was developed by applying the expert system tool to popular control charts. Though some researches on this area has been performed, the implemented results expose many problems in field applications due to the unsatisfactory explanation of the selected control chart and limited knowledge base for resolving the problems. This thesis presented an expert system for control chart as solution for these problems. The expert system for the control chart selection and interpretation is developed by using Turbo C and EXSYS which is an expert system development tool.

Setup planning for machining processes is a part of fixture planning which is also a part of process planning. A setup of a part is defined as a group of features which are machined while the part is fixtured in one single fixture. Setup planning includes a number of tasks such as the selection of setup, sequence of setups and datum frame for each setup. Setup planning is an important function in fixture planning which must be able to support and to clamp a workpiece to prevent deflections caused by machining and clamping loads. This paper presents setup planning system using expert system approach(SPES) for prismatic parts which can be machined on vertical milling machine. SPES consists of preprocessing module and main processing module. Preprocessing module executes the conversion of feature data to frame type data and the determination of setups, and main processing module executes the determination of datum frame of each setup and sequance of setups. Preprocessing module is coded by C language and main processing module is a rule-based expert system using EXSYS pro. The performance of SPES is evaluated through case studies and the results show successful work except for operation sequence of machining holes. This is due to the limited rules for machining holes.
