In this paper, Trajectory Scheduling Methods (TSMs) are proposed for the permutation flowshop scheduling problem with total tardiness minimization criterion. TSMs belong to an iterative local search framework, in which local search is performed on an initial solution, a perturbation operator is...

This study aims to investigate the characteristics of the efficient evolution of China's iron and steel industry against the backdrop of limited openness and regulation and to discuss the important effects of regulatory policy and total factor productivity (TFP) of China's iron and steel...

According to spatial distribution of climate disasters in Nanning City and physiological and ecological indicator demands of sugarcane, with the aid of HJ-1 CCD satellite remote sensing images, basic meteorological data and geographic information data, this paper established the model for...

This paper studies the performance of hybrid methods combining normal and non-normal GARCH-type filters with extreme value theory (EVT) in predicting VaRs of four major stock indices in Chinese stock market. Based on the out-of-sample VaR forecasts results over the 24 models considered, we find...

Interfacial reaction and morphology are investigated between pure iron sheet and aluminum alloy with different silicon additions in hot-dip aluminizing at 700°C. The intermetallic reaction layer hot-dipped in a pure aluminum bath is mainly governed by the diffusion controlled growth of the...

Shiziyang Bay, located in the upstream of the Pearl River Estuary, has frequently suffered from hypoxia since 2000, which has persisted in recent years despite effective controls on anthropogenic pollutant loads. To explore the underlying causes, we investigated changes in dissolved oxygen (DO),...

This paper is an exploratory analysis of the efficacy of parliamentary representation as a means to moderate ethnic conflict in new democracies. We agree with many others that the interests of an ethnic minority group are better protected when the group has access to decision makers, can block...
