Linear assignment problems (AP) arise in different situations to find an optimality to assign k-objects to m-other objects in a one to one manner. It is a combinatorial optimization. The assignment problems find a tremendous application of production planning, telecommunication, economics and so on. In view of this paper, a newly approach this is to say fractional-restriction method is proposed for linear fractional assignment problems (LFAP). Then it is transformed to two linear objective functions of the assignment problem so as to get the optimal solution. The solution procedure is illustrated with the numerical examples. © 2020 IJSTR.

Preference solution for linear fractional assignment problem

A new approach namely, row-column minima method is suggested to find an optimal interval solution for fully interval integer transportation problem (FIITP). In the proposed method, the given FIITP is decomposed into two transportation problem as upper (UBITP) and lower (LBITP) and by applying row-column minima method so as to get the optimal interval solution. Fuzzy concept, midpoint, centre, width, interval ordering and multiobjective technique were not used. The proposed method is easier and also, simply because of arithmetic calculation. Using the proposed method, the numerical example is illustrated. © IJSTR 2020.

Fully interval integer transportation problem for finding optimal interval solution using row-column minima method

Induction motors are generally employed in industries for various applications due to their enhanced performance, intrinsic ruggedness and reliability. Usually monitoring the condition of the induction motor is an arduous task. Also, it is an indispensable need for maintaining the performance of the machine. In this paper, a model for monitoring the condition of the DTC based induction motor drive is proposed using advanced soft computing technique, fuzzy logic. This paper signifies the mathematical modeling of a three phase induction motor drive fed by three phase voltage source inverter using direct torque control strategy. It is necessary that these machines work efficiently with superior quality all the time. Also, If any fault occurs in machine it is essential to identify and diagnose the particular fault within the minimum possible time. Using MATLAB/SIMULINK software, here direct torque control of induction motor is implemented and the various fault issues of induction motor is presented with the help of fuzzy based fault detection system. An intelligent modeling technique is adopted as an identifier for different types of faults. The three phase stator currents are estimated and applied as an input to the fuzzy detector system. In this model, time acts as an important parameter in fault detection and in decision making. It plays a vital role for taking suitable corrective action according to the nature of the fault that occurs in the machine. © 2019 Author(s).

We present a new method namely separation and addition method to solve fully intuitionistic fuzzy linear programming (IFLP) problems. The main advantage is that the nature of the intuitionistic variables were not changed in to crisp by ranking functions. Further, it is decomposed into multi-objective linear programming (MOLP) and linear programming (LP) technique by its arithmetic operation and ordering relations. Numerical example will explain clearly about the proposed method. © 2019 Author(s).

This study is based upon the responses from the students, and teachers in colleges. The survey of colleges: ICT in Education provides detailed and reliable benchmarking of Information and communication Technologies in college level education across Chennai and Vellore districts. We tried to paint a picture on educational technology in colleges: from infrastructure provision to use, confidence and attitudes of students and teachers. The picture of structured model is from unstructured information, leads us to list out the misfits which are in distorted. The correlation errors are traced out and the model is fitted for ICT in education. Inferential statistics are used to validate the model. © 2019 Author(s).
