According to the traditional consumption function theory, his paper makes an empirical research. Based on the existing study, selecte resident's consumption data of China, using China's provincial panel consumer data from 2000 to 2008 to analysis the relationship between population age structure and consumer behavior. The results showed that the youth dependency ratio and the old dependency ratio...
The purpose of the present study was to develop new statistically validated in silico models to predict the toxicity of organic chemicals using multiple linear regression (MLR) and principal components analysis (PCA). This model applied a diverse set of theoretical molecular descriptors for a set of 468 heterogeneous chemicals with the toxicity data of (LC50)96h in Pimephales promela. The established...
A new optimal power flow (OPF) model accounts for electro-thermal coupling relationship is established based on electro-thermal coordination (ETC) concept in this paper This new OPF model organically combines the traditional OPF with heat balance equation (HBE) which reflects thermal dynamic process of transmission component. It considers the temperature limit of transmission component as its security...
This study investigates the moderating role of personality traits on the relationship between customer satisfaction and loyalty. Survey data were collected from shoppers of two supermarkets in Beijing, China. The results show that consumers' characteristic of extraversion is positively related to the level of accrued loyalty, while consumer's characteristic of neuroticism attenuates the association...
As information and communication technologies, the rapid development of service "may be trade-related" elements to improve on a global scale with high-end services has set off a new round of industry, characterized by the transfer of wave, namely, "service outsourcing." Based on the basic theory of CAS, as well as gathering together the main characteristics of the proposed service...
In a construction project where duration truly equals money, the management of duration is critical, thus predicting the likelihood of duration may play a key role towards project success. On the basis of the researches of other scholars, this paper analyzed the traditional probability analysis method for duration risk in program evaluation and review technique(PERT). On basis of that it simulates...
It is well known that construction project management involves such objectives as duration, cost, quality, resource leveling and so on. It is necessary to integrate and balance multiple objectives in management process. So this paper firstly analyzes single-objective optimization models such as duration-cost model, duration-quality model and resource leveling model and the relationship between duration,...
