Expert system (ES) is a consultation intelligent system uses the artificial intelligence concepts and reasoning methodologies to solve problems in a specific domain. This system contains the knowledge and experiences of many experts in such domain. The purpose of an ES is not to replace the experts, but simply to make their knowledge and experience more widely available. ES permits others to in...

We describe the development of a ten-question diagnostic designed to characterize the estimation skills of undergraduate students in science and engineering. In order to establish a baseline and look for possible gains in skill level we have developed a multiple-choice assessment designed to probe student ability and confidence in estimating physical quantities such as mass, size, and time. The...

Finding the right software is often hindered by different criteria as well as by technology changes. We performed an analytic hierarchy process (AHP) analysis using Expert Choice to determine which data mining package was best suitable for us. Deliberating a dozen alternatives and objectives led us to a series of pair-wise comparisons. When further synthesizing the results, Expert Choice helped...

In many retail situations, customers today face vast assortments and often have limited ability to find exactly what they need. By implementing a need-based toolkit for assortment matching, retailers can limit this complexity of choice, increasing the satisfaction of consumers with the goods acquired. Building such a need-based system however is costly and time-consuming, as expert knowledge an...

In applied mathematics, electronic and chemical engineering, the modelling process can produce a number of mathematical problems which require numerical solutions for which symbolic methods are either not possible or not obvious. With the plethora of numerical library routines for the solution of these problems often the numerical analyst has to answer the question Which routine to choose? and ...
