Supply Chain Coordination with CVaR Criterion
In a conditional value-at-risk (CVaR) framework, it is shown that the supply chain can be coordinated with the revenue-sharing, buy-back, two-part tariff and quantity flexibility contracts and that the risk-averse retailer can increase its profit by raising its risk- averse degree under mild conditions.

It is demonstrated that the sparsity decides the uniformity of the transformed data, and that could be a good reason to explain both the success of the bucket sort in PennySort 2003 and the failure for the same algorithm with the data modified.
Competitive Analysis of Two Special Online Device Replacement Problems
The two-stage model with and without the interest rate respectively is explored and the risk-reward model is introduced to analyze this problem and improve the competitive ratio performance.
Two Types of Risk-averse Newsvendor Models with Limited Capacity
Performance as a signal to Information Asymmetry Problem in Online Peer-to-Peer Lending
A model is proposed to evaluate how performance – individual and group can be used as signals to reduce information asymmetry problems and how these performance signals can interact with lenders risk attitude to affect funding success.

The classical newsvendor problem is extended by introducing a downside risk constraint from the perspective of inventory control by analyzing the form of the optimal order quantity when the probability that the cost level is larger than or equal to a fixed cost constant is less than a fixed value of probability.
