Evaluation of Grey Forecasting Method in Total Indonesian Production Crude Oil and Condensate

“…The Grey forecasting method has been successfully applied in many areas of research including finance [9,11,16,17], engineer [2,12,13,14,20,21,23,24], and management [3,10,15,19,22,25].…”

Objective Grey Prediction Filtering Algorithm Based on Combined Model

“…Grey prediction method is a simple and practical prediction method which focuses on the future behavior of the system [2], it can dig out the inherent movement law of target through Supported processing historical position information of the moving target , and it has no limit to target motion, so it can objectively predict the trajectory of maneuvering target when it is in battle, however, the Kalman prediction filtering method often assumes that the target does uniform motion and uniformly accelerated motion [3], but in practice because of the perspective of camera, the equidistant points along a certain direction in geodetic coordinate system is hard to be equidistant when it mappings to the Axis coordinate system of stable platform, so the actual predictive accuracy in tracking maneuvering target is low. In this paper, we take a certain type of triaxial TVguide target tracking device for practical subjects, through the analysis of photoelectric tracking target signal, combining with the method of grey prediction theory, analyze the problems of traditional grey prediction algorithm, put forward a improved algorithm based on GM(1,1) model, and design a target grey prediction filtering algorithm based on combination model through using time-series method to establish residual error model of grey prediction, not only ensure the real time of algorithm, but also improve the prediction accuracy.…”

Evaluation of Grey Forecasting Method of Total Domestic Coffee Consumption in Indonesia

“…On the other hand, a longitudinal study by Deng [3,4,5,6] reported that the first systematic study of Grey theory in 1982, which has been recognized and applied by many academicians in different subjects such as economic prediction [20,24,25,29,31], material science [11,12,14,15], electrical power [2,8,9,10], traffic [7,17,21,26], technological progress [1,13,16], engineering [18,19] and agriculture [22], chosen Grey prediction as an ability forecasting means because of having relatively low data requirements, and a GM model constructed from a sample of just four pieces of data.…”
