The daily clearing price curve in electricity market varied with multi-period and strong fluctuation characteristic. When grey GM (1, 1) model is used in forecast, the forecast error exceeded the permitted precision. This is because GM (1, 1) model is invalidated only if the price series did not follow the rule of exponential growth. In this case, grey model with period residual modification is proposed,...
A predictive control algorithm for probability density function (PDF) is presented based on the rational square-root B-spline based PDF model. The rational square-root PDF model is studied first, based on the analysis of the relationship between the pseudo weight and the actual weight, the rational square-root B-spline model can be easily set up; then the predictive model is deduced; a performance...
Settlement of municipal solid waste landfill lasts a very long period of time, and it is of great importance to determine or predict the settlement process in order to reasonably design waste filling art and choose good prevention methods to ensure the safety of associated facilities built on the top of the landfill. In this paper, we deeply study the models for the settlement process. First, mathematical...
