Dynamic grouping of parts in flexible manufacturing systems - a self-organizing neural networks approach

Article Abstract:

The use of a neural network, the self-organizing map (SOM) network, as a clustering tool in the application of group technology (GT) to flexible manufacturing systems was investigated. The approach, which was implemented in a problem with 43 parts and 16 machines to compare its performance with other GT methodologies, enables quick responses to modifications in parts design, process plans and operating conditions. A framework for constructing an intelligent decision support system based on SOMs and knowledge bases is likewise developed.

Knowledge-based DSS for construction contractor prescreening

Article Abstract:

A knowledge-based decision support system (DSS) that enables sureties to evaluate a contractor's probability to file a claim on its surety contract construction bonds is introduced. The DSS, which uses contractor financial data as input, is based on inductive learning, neural networks and statistical models of multiple discriminate, regression and logistic regression analysis. It carries out 'what-if' decision analysis based on the integrated outcome of each model and updated knowledge.

Editorial

Article Abstract:

Knowledge-based technology has greatly influenced the development of new approaches to decision analysis and decision support. At present, decision-making technology may be grouped into three classes, ranging from knowledge-based decision aids and intelligent decision-modeling systems to decision-analytic expert systems. Several examples of such systems are presented.
