This paper investigates technology investment under flexible capacity strategy with demand uncertainty. Technology investment enables a firm to reduce its total production cost, while flexible capacity strategy aims to reduce a firm׳s production waste by postponing production until demand is...

This paper investigates an electricity time-of-use (TOU) tariff problem with the consideration of consumer behavior. Under the TOU tariff, we consider two periods: the peak and base periods. A two-level model is established to solve the TOU tariff problem: in the upper level, the producer...

We study the problem of scheduling n non-preemptive jobs on m unrelated parallel machines. Each machine can process a specified subset of the jobs. If a job is assigned to a machine, then it occupies a specified time interval on the machine. Each assignment of a job to a machine yields a value....

We develop a non-linear forecast combination rule based on copulas that incorporate the dynamic interaction between individual predictors. This approach is optimal in the sense that the resulting combined forecast produces the highest discriminatory power as measured by the receiver operating...

In order to fully understand sugarcane production in Guangxi in 2013, the sample survey combined with data collection and field survey was carried out in sugarcane production areas in Nanning, Hechi, Liuzhou, Chongzuo, Baise and Laibin from May 28 to June 36 in 2013. It was found that the...

We propose autocorrelation-robust asymptotic variances of the Brier score and Brier skill score, which are generally applicable in circumstances with weak serial correlation. An empirical application in macroeconomics underscores the importance of taking care of serial correlation. We find that...

Buildings account for about 40% of the global energy consumption and contribute over 30% of the CO2 emissions. A large proportion of this energy is used for thermal comfort in buildings. This paper reviews thermal comfort research work and discusses the implications for building energy...

Correlation between clearness index and sunshine duration is useful to the estimation of the solar radiation for areas where measured solar radiation data are not available. Regression techniques were used to investigate the correlations between daily global solar radiation and sunshine duration...

This short technical note presents an attempt to develop a new climatic variable Z for assessing climate change (global warming) with respect to the built environment. Principal component analysis of long-term (30-year) dry-bulb temperature (DBT), wet-bulb temperature and global solar radiation...
