The analysis of Tobit model with non-normal error distribution is extended to the case of asymmetric Laplace distribution (ALD). Since the ALD probability density function is known to be continuous but not differentiable, the usual mode-finding algorithms such as maximum likelihood can be...

Based on the conventional ground observational data, a numerical simulation and moist potential vorticity (MPV) analysis has been carried on heavy rainfall event over Jiangxi province from 19 June to 20 June 2010, with a meso-scale rainstorm model. The results show that this rare rainstorm is a...

This paper investigates minimization of both the makespan and delivery costs in on-line supply chain scheduling for single-machine and parallel-machine configurations in a transportation system with a single customer. The jobs are released as they arrive, which implies that no information on...

A stochastic model with hidden discrete Markov processes is constructed to understand the behavior of debtors.

As a major contributor to productivity and employment in China, the petroleum refining industry consumes approximately 15% of industrial fuel oil and 10% of industrial coal. Given this energy-intensive characteristic, cost-effective investments for energy-efficient technologies may be a useful...
