There is a great diversity of ways to use fuzzy inference in robot control systems, either in the place where it is applied in the control scheme or in the form or type of inference algorithms used. On the other hand, artificial neural networks ability to simulate nonlinear systems is used in different researches in order to develop automated control systems of industrial processes. In these applications of neural networks, there are two important

Mathematical model of multiple objective linear fractional programming problem is analyzed with respect to linguistic variables based solving methods. Two propositions are formulated related to choosing possibilities of aggregation coefficients for fractional criteria; membership functions. Computational results are developed in order to highlight theoretical remarks related to membership functions; for efficiency needed properties.
