The increasing damage caused by disasters is a major challenge for disaster management authorities, especially in instances where simultaneous disasters affect different geographical areas. The uncertainty and chaotic conditions caused by t...
Sourcing decisions with loss aversion under yield and demand randomness [0.03%]
具有损失厌恶的随机产能及市场需求中的外包决策研究
