The classic newsvendor problem focuses on maximizing the expected profit or minimizing the expected cost when the newsvendor faces myopic customers. However, it ignores the customer’s bargain-hunting behavior and risk preference measure of the news

We study a dyadic supply chain with firms following the Rawlsian principle of fairness and examine its impact on chain performance and firms’ profits. Different from the inequality-aversion model in the distributional fairness literature, the parti

Uncertainty is a main source of opportunistic behaviors in research and development cooperations, which challenges strategic decisions ranging from investments to operations. To avoid opportunism arising in cooperations, commitments (either formal co

We study a cardinality-constrained optimisation problem with nonnegative variables in this paper. This problem is often encountered in practice. Firstly, we study some properties on the optimal sol...

In this paper, we study complexity results of sparse optimization problems and reverse convex optimization problems. These problems are very important subjects of optimization problems. We prove that the complexity result of the sparsity constraint p

We have observed four modes of cost reduction in supply chains from practice. In particular, considering a supply chain with one manufacturer and one retailer, we identify four modes: the manufacturer solely invests, the retailer solely invests, or b

Problem Definition: Quick response is a classic operations strategy, under which a retailer can place a second order for rapid replenishment during the selling season after learning more about market demand. This paper examines the value of quick res
