A Generalized Model for Fuzzy Linear Programs with Trapezoidal Fuzzy Numbers

open access: yesJournal of Applied Research on Industrial Engineering, 2017
In this paper, we generalize a linear programming problem with symmetric trapezoidal ‎fuzzy number which is introduced by Ganesan and et al. in [3] to a general kind of trapezoidal fuzzy number. In this way, we first establish a new ‏arithmetic operation

Sparsity Prevention Pivoting Method for Linear Programming

open access: yesIEEE Access, 2018
When the simplex algorithm is used to calculate a linear programming (LP) problem, if the matrix is a sparse matrix, it will be possible to lead to many zero-length calculation steps, and even iterative cycle will appear.

Gaussian and Lerch Models for Unimodal Time Series Forcasting

open access: yesEntropy, 2023
We consider unimodal time series forecasting. We propose Gaussian and Lerch models for this forecasting problem. The Gaussian model depends on three parameters and the Lerch model depends on four parameters.

A modified simplex based direct search optimization algorithm for adaptive transversal FIR filters

open access: yesScience Progress, 2021
In this paper, a novel modified optimization algorithm is presented, which combines Nelder-Mead (NM) method with a gradient-based approach. The well-known Nelder Mead optimization technique is widely used but it suffers from convergence issues in higher ...

On the simplex, interior-point and objective space approaches to multiobjective linear programming

open access: yesJournal of Algorithms & Computational Technology, 2021
Most Multiple Objective Linear Programming (MOLP) algorithms working in the decision variable space, are based on the simplex algorithm or interior-point method of Linear Programming.
