Cardinality constrained mean-variance (CCMV) portfolio selection problem is commonly formulated as a mixed integer quadratic program (MIQP) that can be solved by a branch-and-bound scheme or metaheuristics. Yet, computational efficiency remains to be a major issue. In this study, we propose a...

In this paper, we study a novel network design problem for the fourth-party logistics network (4PLN) to cope with accidental demand surges. A chance-constrained stochastic programming model is established to minimize the overall cost for 4PLN under service-level targets, where the stochastic...

This paper studies a pricing game in which two sellers compete to sell a product to a customer with bounded rationality. The sellers have different production costs in determining their respective prices to offer to the buyer. The buyer prefers the seller offering a lower price, but may suffer...
