This paper investigates the pricing and production game in a decentralized assembly system that consists of one assembler and two independent suppliers. One supplier is able to exert the push contract on the assembler so as to transfer all his inventory risk, while the other supplier has to...

This paper considers the inventory management in a VMI programme consisting of a vendor, a retailer and a VMI warehouse near the retailer. Specifically, the vendor is authorised to manage the inventory of the VMI warehouse through (Q, r) policy, and the retailer controls the service level of the...

Consider a semiparametric model yi = xi' beta + g(ti )+ei; i = 1;2..., n, error ei are i.i.d. random variables from unknown distribution f(e). In this paper, we propose a nonlinear wavelet estimator ^f(e) of f(e) based on residuals ê =yi - ^yi here restriction of uniformly continuous on f(e)...

In this paper, synthetic aperture radar (SAR) data from ENVISAT ASAR ascending, descending and ALOS PALSAR ascending orbits are collected to investigate the coseismic displacements of the Mw 6.4 earthquake occurred in Gaize, Tibet on January 9, 2008 and the Mw 5.9 aftershock on January 16, 2008....

Differential interferometric synthetic aperture radar (D-InSAR) has been viewed as a promising technique in monitoring sudden geo-hazards (e.g., earthquake and landslide) in mountainous areas. However, the tough natural settings (e.g., steep slopes and vegetation) pose the D-InSAR technique to...

Debris flow with intermittent surges is a major natural hazard. Accurate estimation of the total volume of debris flow is a challenge for academic researchers and engineering practitioners. This paper has proposed a new model for the total volume estimation based on 15 years of observations in...
