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...

Consumption theory and its optimization mechanism may be applied to the U.S. presidential elections. Based on Clower’s Dual-Decision Hypothesis (DDH), Wu (2017) derived the result showing change in savings is a function of labor income growth. Under DDH, consumers make optimal decision based...

Keynes’ General Theory (1936) is probably the most challenging economics book ever written, with an abundance of hypotheses, concepts and theories. Twenty five years after its publication, Clower proposed an insightful explanation on Keynes, the Dual-Decision Hypothesis (DDH). Hall (1978) and...

Though Wu (2017) has shown Clower’s Dual Decision Hypothesis leading to Keynes’ change in saving (and disequilibrium) conclusion, it is important to compare Clower’s budget constraint approach with other models, including those found in Hall’s consumption theorem and similar approach. In...

This new version uses the definitions and some of the results found in Sargent’s Macroeconomic Theory. Hall’s (1978) proof of the corollary 4, ct+1 = ct, can be found in Flavin (1981). Writing the same consumption stated in Flavin, for period t+1, in a different way for the summation of the...

During the 2016 U.S. election, many voters from democratic (‘blue wall’) states, which have voted consistently in the past elections for the democrats, suddenly moved back into the Republican fold. During this election, the primary economic issue was supposed to be NAFTA, both Bernie Sanders...

Rapid urbanization and industrialization lead to high emissions and accumulation of halogenated flame retardants (HFRs), which seriously stress the health of the eco-environment. To explore the impacts of urbanization and industrialization on the occurrence and health risks of HFRs, the...

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...
