A novel approach, based upon fuzzy logic and frames, for the creation of fuzzy expert shell is being proposed in this paper. The fuzzy logic effectively deals with the type of communication normally used by humans, whereas the frames have been used to store the correlated information in the form of a block. This shell uses a local inference mechanism within the frame with the help of a multicri...

The aim of this study was to improve efficiency of the food aid distribution process of international food relief organizations. An overall objective of this study was to develop a prototype expert system for monitoring and evaluating food aid by international disaster relief organizations. The research identifies data related to monitoring and evaluation processes of various international food...

This paper describes a shell that has been developed for the purpose of fuzzy qualitative reasoning. The relation among object predicates is defined by object trees that are fully capable of dynamic growth and maintenance. The qualitatively fuzzy inference engine and the developed expert system can then acquire a virtual-rule space that is exponentially (subject to machine implementation consta...

Successful machine diagnosis consists not only of sound diagnostic reasoning, but also the selection of appropriate repairs, sequencing the repairs correctly, interactively validating the success of each repair, and performing follow-on diagnosis in case of repair failure. We discuss some of the issues involved in formulating a repair strategy for an expert system, review some aspects of expert...

In this paper, we present the FOLtoNL system, which converts first order logic (FOL) sentences into natural language (NL) ones. The motivation comes from an intelligent tutoring system teaching logic as a knowledge representation language, where we use it as a means for feedback to the users. FOL to NL conversion is achieved by using a rule-based approach, where we exploit the pattern matching ...

The paper describes the application of an expert system to develop the carbide cutting tools selection system for computer numerical control (CNC) lathe machine. The aim of the development is to select the optimum tool holder, carbide cutting tools, insert, feed rate, and turning speed for CNC lathe machine. The system is able to select the suitable tips tool based on the dimension, machining p...

Methods and tools for the static and dynamic verification and validation of software systems are commonplace in the field of software engineering. In the field of expert systems, where it is more difficult to ensure that a system meets the specifications and expectations than in traditional software engineering, such tools are generally not available. In this paper, the need for more support of...

The ISO 9000 quality management system has been widely accepted and adapted as a national standard by most industrial countries. Despite its high popularity and the urgent demand from customers to implement ISO 9000, some major concerns for those organizations that are seeking registration to ISO 9000 include the expensive cost and the lengthy time to implement. The purpose of this paper is to ...
