Customer Retention is a major aspect of the growth of any business. It is always good to retain those customers who are more loyal or can be converted to be loyal. In this paper, a fuzzy decision tree based approach is proposed in combination with Z-shaped curved membership function to find the customer loyalty and has been compared with the approach of fuzzy decision tree with Gaussian members...

The linear multiobjective transportation problem is a special type of vector minimum problem in which constraints are all equality type and the objectives are conicting in nature. This paper presents an application of fuzzy goal programming to the linear multiobjective transportation problem. In this paper, we use a special type of nonlinear (hyperbolic and exponential) membership functions to ...

In this study, the roll, yaw and depth fuzzy control of an Au- tonomous Underwater Vehicle (AUV) are addressed. Yaw and roll angles are regulated only using their errors and rates, but due to the complexity of depth dynamic channel, additional pitch rate quantity is used to improve the depth loop performance. The discussed AUV has four aps at the rear of the vehicle as actuators. Two rule bases...
