This paper presents a multi-objective optimization model for a green supply chain management scheme that minimizes the inherent risk occurred by hazardous materials, associated carbon emission and economic cost. The model related parameters are capitalized on a big data analysis. Three scenarios are proposed to improve green supply chain management. The first scenario divides optimization into three options: the first involves minimizing risk and then dealing with carbon emissions (and thus economic cost); the second minimizes both risk and carbon emissions first, with the ultimate goal of minimizing overall cost; and the third option attempts to minimize risk, carbon emissions, and economic cost simultaneously. This paper provides a case study to verify the optimization model. Finally, the limitations of this research and approach are discussed to lay a foundation for further improvement.

The study proposes an evolutionary game model to investigate the possible, responses of enterprises to incentive policies related to the implementation of a carbon reduction labeling scheme, such as a direct subsidy and preferential taxation rates. System dynamics is applied to simulate the created game model and we analyze two scenarios, namely the individual and combined intervention of incentive policies. A case study of China's air conditioner enterprises is then examined, with the simulation results highlighting that both a direct subsidy and preferential taxation positively influence the implementation of the carbon reduction labeling scheme. In particular, the combination of these two incentive policies is efficient compared with individual policy making. Finally, the limitations of the game theoretical analysis are discussed and future research directions are provided. (C) 2016 Elsevier Inc. All rights reserved.

This report described a facile process for the preparation of 2D/OD MoS2-SiO2 hybrids using a simple in situ growth method, with the purpose of promoting the dispersion of MoS2 in polymer matrices and improving the properties of polymer materials. FTIR, XPS, TGA and TEM measurements were performed to characterize the structure and morphology of the synthesized hybrids which were then introduced into epoxy to reduce flammability. The hybrids dispersed well in the epoxy matrix. No obvious agglomerations were observed. In comparison with those of neat epoxy, the incorporation of a low loading of MoS2-SiO2 hybrids resulted in significant decrements in heat release rate, total heat release and volume of toxic effluents released during combustion, which indicated that the fire hazards of epoxy composites were strongly reduced. The good dispersion, labyrinth barrier effect and the catalytic effect of MoS2-SiO2 hybrids on char formation may contribute to the observed decrease in the flammability of epoxy resin.
