A Fuzzy-Neural Ensemble and Geometric Rule Fusion Approach for Scheduling a Wafer Fabrication Factory

Table 2

The differences between the proposed methodology and the previous methods.

Method	Way of fusing rules	Estimating the remaining cycle time	Optimization method	Heuristic	Digital manufacturing model is used for	Required evaluation rime
Hsieh et al. [5]	NA	NA	NA	Simulation	Evaluating/comparing scheduling performances	Lengthy
Dabbas et al. [26]	Linear	NA	DOE + the desirability function	Simulation	Evaluating/comparing scheduling performances	Lengthy
Harrath et al. [7]	Linear	NA	Enumeration	Association rule	Evaluating/comparing scheduling performances	Lengthy
Chen [29]	Nonlinear	FCM-BPN	Maximize the standard deviation of slacks	NLP	Confirmation study	Moderate
The proposed methodology	Nonlinear	FCM-BPN ensemble	Maximizing the geometric mean of the neighboring distances of slacks	NLP + systematic procedure	Confirmation study	Short
