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

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...

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...

Outlines the development of the construction sector in the period 1980-2001, e.g. the employment in collective-owned vs. state-owned enterprises, the influx of rural workers, role of labour contractors, and the impact of using pre-fabricated concrete and interior fittings such as doors, flooring...

Let $(X_t)_{t\ge0}$ be a continuous-time, time-homogeneous strong Markov process with possible jumps and let $\tau$ be its first hitting time of a Borel subset of the state space. Suppose $X$ is sampled at random times and suppose also that $X$ has not hit the Borel set by time $t$. What is the...
