Modification of the Grey Evaluation Model Based on the Optimization of a Center-point Triangular Whitenization Weight Function

摘要

We study the modification of the grey evaluation method with the aim of defining the center of the triangular whitenization weight function. We characterize the centers and weights of the attribute distribution ranges based on interval numbers. A grey entropy optimization model for the center-points and attribute weights is established using the minimum grey entropy of the evaluation results. To solve the model, a particle swarm optimization (PSO) algorithm is developed. We provide an example that illustrates the application and feasibility of the suggested method.
