An expert system for group technology

One way of solving the group technology (GT) problem is by using an expert system combined with algorithms. According to the tandem system architecture, the expert system selects an appropriate model and algorithm for solving the GT problem. In addition, the expert system closely interacts with the model selected. For example, it may modify constraints, evaluate partial solutions or change the parameters of the model. In EXGT, which is under development, GT problems have been divided into three classes.
