Based on the traditional trip attraction model, a new method of operation condition evaluation and supply scale forecasting for public parking facilities is proposed. It begins with the operation condition investigation of existing parking facilities, and then analyzes qualitatively the existing parking facilities supply scale by four indexes. Finally, it can calculate the supply scale in predi...
The establish of the indicator system, the selection of evaluation forecasting model and the integration of the system are the three main problems in the regional sustainable development decision support system. A great deal of indicator systems and professional models have been put forward in many special researches and reports. How to supply the government departments with a reasonable indica...
In this article, we develop and study methods for evaluating forecasters and forecasting questions in dynamic environments. These methods, based on item response models, are useful in situations where items vary in difficulty, and we wish to evaluate forecasters based on the difficulty of the items that they forecasted correctly. In addition, the methods are useful in situations where we need t...
This paper utilizes the nonparametric functional autoregressive approach (FAR) to model the time-varying distribution of UK monthly inflation rates using disaggregated cross-sectional data. Our approach is free of any assumptions on the class or structure of the density functions themselves, or the number of dimensions in which the densities may vary. The “pseudo real time” in-sample forecastin...
The transmission lines are exposed to the atmosphere nature and will be affected by adverse weather such as lightning storm, so that it will affect the reliability of transmission system. This paper studies the fault probability model of transmission line during the lightning storm, and evaluates the short-term reliability of transmission system in the forecasting weather condition. Firstly, bu...
This chapter reviews the econometric methods that are used by health economists to model health care costs. These methods are used for prediction, projection and forecasting, in the context of risk adjustment, resource allocation, technology assessment and policy evaluation. The chapter reviews the literature on the comparative performance of the methods, especially in the context of forecastin...
Electricity demand forecasting model based on single algorithm at least have two problems related to local optima and computational cost. We consider to utilised the hybrid real value genetic algorithm and extended Nelder-Mead to solved local optima and reduced the number of iteration. The model is known as the hybrid Real-Value GA and Extended Nelder-Mead (RVGA-ENM). The GA has been enhanced t...
The transmission line project cost index, which reflects price changes of transmission line project components affecting project cost, is an integrated indicator. Based on the constitution of the transmission line project cost index, 324 transmission line project cost index during 2002 and 2010 were selected, in order to describe variation tendency of the transmission line project cost index in...
