Abstract: In aviation Maintenance, Repair, and Overhaul (MRO) systems, spare parts inventory management faces highly stochastic demand, significant tail risks, supply delays, and complex contractual constraints, making it difficult for traditional deterministic or risk-neutral models to balance high service levels with low costs. This paper proposes a multi-... 展开更多 -

Abstract: The upgrading of ethanol into gasoline-range biofuels relies critically on efficient carbon–carbon coupling strategies, among which the Guerbet reaction and ethylene oligomerization pathways play central and complementary roles. This review focuses on these two mechanistic platforms as core routes for controlled carbon chain growth from ethanol-der... 展开更多
